1. sdwebImage使用：
1.1.基本使用
#import "ViewController2.h"
#import "UIImageView+WebCache.h"
#import "MJExtension.h"
#import "XmgVideo.h"
#import "GDataXMLNode.h"
#include "Main.h"
#import "AFNetworking.h"
#import "Person.h"
#import "Reachability.h"
#import "NSString+Hash.h"
- (void)viewDidLoad {
[super viewDidLoad];
// 1. 图片 下载 简单方法
[self.myWebImage sd_setImageWithURL:[NSURL URLWithString:@"http://img5.mtime.cn/mg/2019/06/27/224744.68512147_120X90X4.jpg"]];
// options 图片下载策略
/*
// 下载失败重新下载
SDWebImageRetryFailed = 1 << 0,

SDWebImageLowPriority = 1 << 1,
不做沙盒缓存
SDWebImageCacheMemoryOnly = 1 << 2,

SDWebImageHighPriority = 1 << 8,
SDWebImageDelayPlaceholder = 1 << 9,
SDWebImageTransformAnimatedImage = 1 << 10,
SDWebImageAvoidAutoSetImage = 1 << 11,
SDWebImageScaleDownLargeImages = 1 << 12
*/
// 2. 图片下载 完整方法
// [self.myWebImage sd_setImageWithURL:[NSURL URLWithString:@"http://img5.mtime.cn/mg/2019/06/27/224744.68512147_120X90X4.jpg"] placeholderImage:nil options:kNilOptions progress:^(NSInteger receivedSize, NSInteger expectedSize, NSURL * _Nullable targetURL) {
// //receivedSize 已经下载大小
// //expectedSize 总的大小
// } completed:^(UIImage * _Nullable image, NSError * _Nullable error, SDImageCacheType cacheType, NSURL * _Nullable imageURL) {
//
// }];
}button设置图片 可以设置状态：UIControlStateNormal ，请求网络图片的时候
// 通过 <UIButton+WebCache.h>
[button sd_setImageWithURL:[NSURL URLWithString:square.icon] forState:UIControlStateNormal placeholderImage:[UIImage imageNamed:@"setup-head-default"]];
// 通过<UIImageView +WebCache.h>
// [button.imageView sd_setImageWithURL:[NSURL URLWithString:square.icon] placeholderImage:[UIImage imageNamed:@"setup-head-default"]];2. 缓存清理 AppDelegate 内存告急回调
-(void)applicationDidReceiveMemoryWarning:(UIApplication *)application{
// 1.取消当前所有任务
[[SDWebImageManager sharedManager] cancelAll];
// 2. 清理缓存
// 直接删除文件夹
[[SDWebImageManager sharedManager].imageCache clearDiskOnCompletion:^{
}];
}2. ios Json解析方案:
苹果原生： NSJSONSerialization
2.1. json 字符串 转 oc 对象
2.2. oc 对象 转 jons字符串
-(void)touchesBegan1:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
NSString* test=@"{\"username\":\"xiaming\"}";
// NSString* test=@"[\"xiaonig\",\"xiaohei\"]"; // __NSSingleEntryDictionaryI
// NSString* test=@"\"error\""; // NSTaggedPointerString
// NSString* test=@"true"; // __NSCFBoolean
// NSString* test=@"null"; // NSNull
// 把Json 转化为 OC 对象
// NSJSONReadingAllowFragments: 如果直接返回一个"error",不是标准json，一定要用这个,不用这个返回nil
//kNilOptions : 默认是这个,性能是最后的
id obj = [NSJSONSerialization JSONObjectWithData:[test dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingAllowFragments error:nil];
NSLog(@"%@",[obj class]);
// OC 对象 转化 json 字符串
NSDictionary* dict= @{
@"username:":@"xiaming"
};
/* Returns YES if the given object can be converted to JSON data, NO otherwise. The object must have the following properties:
- Top level object is an NSArray or NSDictionary
- All objects are NSString, NSNumber, NSArray, NSDictionary, or NSNull
- All dictionary keys are NSStrings
- NSNumbers are not NaN or infinity
Other rules may apply. Calling this method or attempting a conversion are the definitive ways to tell if a given object can be converted to JSON data.
oc - > json 条件
1. 最外层是 字段或者 数组
2. 元素必须是 NString NSNumber NSArray NSDictionary, or NSNull
3. 所有的字典key 必须是 NString
4. NSNumbers 不能是null 或者 无穷大
*/
BOOL isValid= [NSJSONSerialization isValidJSONObject:dict];
NSLog(@"isValid=%d",isValid);
NSData* data= [NSJSONSerialization dataWithJSONObject:dict options:kNilOptions error:nil];
NSLog(@"%@",[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
}3. ios xml 解析:
3.1. XSXMLParser: sax 方式解析
// 1.创建 sax 解析器
// 2. 设置代理
3. 开始解析
4. 代理中监听解析方法即可
person.xml 本地文件：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE students SYSTEM "student.dtd">
<students>
<student ID="1" movieName="xiaming" ></student>
<student ID="2" movieName="xiaohei" ></student>
<student ID="3" movieName="xiaoze" ></student>
</students>
XmgVideo:
#import <Foundation/Foundation.h>
NS_ASSUME_NONNULL_BEGIN
@interface XmgVideo : NSObject
@property(nonatomic,assign) NSInteger ID;
@property(nonatomic,copy) NSString* movieName;
@end
NS_ASSUME_NONNULL_ENDOC代码：
@interface ViewController2 ()<NSXMLParserDelegate>
@property (weak, nonatomic) IBOutlet UIImageView *myWebImage;
@property(nonatomic,strong) NSMutableArray* videos;
@end
@implementation ViewController2
-(void)touchesBegan6:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
NSString* xmlPath = [[NSBundle mainBundle] pathForResource:@"person.xml" ofType:nil];
NSString* str1 = [[NSString alloc] initWithContentsOfFile:xmlPath encoding:NSUTF8StringEncoding error:nil];
NSData* data= [str1 dataUsingEncoding:NSUTF8StringEncoding];
// 1.创建 sax 解析器
NSXMLParser* parser= [[ NSXMLParser alloc] initWithData:data];
// 2. 设置代理
parser.delegate= self;
// 3. 开始解析
[parser parse];
// NSLog(@"%@",str1);
}
// 开始解析 xml 文档
-(void)parserDidStartDocument:(NSXMLParser *)parser{
NSLog(@"start xml parse");
}
// 解析xml 每一个元素
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary<NSString *,NSString *> *)attributeDict{
// 每一个元素名字 每一个标签属性集合 attributeDict
NSLog(@"start--%@---%@",elementName,attributeDict);
[self.videos addObject: [XmgVideo mj_objectWithKeyValues:attributeDict]];
}
// 解析xml 每一个元素的结束
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
NSLog(@"end");
}
// 解析完成了
-(void)parserDidEndDocument:(NSXMLParser *)parser{
NSLog(@"start xml end");
NSLog(@"result==%@",self.videos);
}
@end3.2. 第三方库：
libxml2 : 存 c 的 ， 支持dom/sax解析， 默认包含在ios sdk中
Gdataxml: dom方式解析，google开发,基于 libxml2
1. 拖入 Gdataxml 库以后出现 问题
错误 提示： 提示：
// libxml includes require that the target Header Search Paths contain
//
// /usr/include/libxml2
//
// and Other Linker Flags contain 搜索 Other Linker Flags 添加 -lxml2
//
// -lxml2
解决方式：
1. 添加 /usr/include/libxml2 配置 -lxml2 同理
报错： Gdataxml 为MRC， 把MRC 不用管，直接ARC 编译
错误：
解决：
OC 代码：
-(void)touchesBegan7:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{ NSString* xmlPath = [[NSBundle mainBundle] pathForResource:@"person.xml" ofType:nil]; NSString* str1 = [[NSString alloc] initWithContentsOfFile:xmlPath encoding:NSUTF8StringEncoding error:nil]; NSData* data= [str1 dataUsingEncoding:NSUTF8StringEncoding]; GDataXMLDocument* doc= [[GDataXMLDocument alloc] initWithData:data options:kNilOptions error:nil]; NSArray* eles= [doc.rootElement elementsForName:@"student"]; for (GDataXMLElement* ele in eles) { NSLog(@"%@", ele); XmgVideo* video= [XmgVideo new]; video.movieName= [ele attributeForName:@"movieName"].stringValue; video.ID = [ele attributeForName:@"ID"].stringValue.integerValue ; [self.videos addObject:video]; } NSLog(@"结果:%@",self.videos); }
4. 文件压缩： 第三方压缩框架 ZipArchive
如果报错，添加第三方库：
OC代码实现 ：
-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
[self zip];
}
-(void)unZip
{
/*
第一个参数:要解压的文件在哪里
第二个参数:文件要放到什么地方
*/
[Main unzipFileAtPath:@"/Users/xiaomage/Desktop/vvv.zip" toDestination:@"/Users/xiaomage/Desktop/yy"];
}
-(void)zip
{
NSArray *arrayM =@[
@"/Users/denganzhi/Desktop/from/1.png",
@"/Users/denganzhi/Desktop/from/2.png",
@"/Users/denganzhi/Desktop/from/3.png"
];
/*
第一个参数:创建的zip放在哪里
第二个参数:要压缩哪些文件
*/
[Main createZipFileAtPath:@"/Users/denganzhi/Desktop/demo.zip" withFilesAtPaths:arrayM];
}
-(void)zip2
{
/*
第一个参数:创建的zip放在哪里
第二个参数:要压缩的文件路径
*/
[Main createZipFileAtPath:@"/Users/denganzhi/Desktop/vvv.zip" withContentsOfDirectory:@"/Users/denganzhi/Desktop/from"];
}5. NSURLSessionTask 和 mj 字典转模型使用
// NSURLSessionTask 和 mj 字典转模型使用
-(void)touchesBegan9:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
NSLog(@"%@",@"发送网络请求");
// MJEXtensio 别名配置，字典中名字 和模型中 对应不上
[XmgVideo mj_setupReplacedKeyFromPropertyName:^NSDictionary *{
return @{
@"ID":@"id"
};
}];
//1. 创建 NSURLSession
NSURLSession * session= [NSURLSession sharedSession];
// 2. 根据请求对象 创建 task
NSURLRequest* request= [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://api.m.mtime.cn/PageSubArea/TrailerList.api"]];
NSURLSessionTask* dataTask= [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
// 解析数据
// NSLog(@"%@",[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
NSDictionary* dictM = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
// 字典转模型 MJExension
NSArray *arrayM = dictM[@"trailers"];
//字典转模型, 通过类工厂方法 或者
// kvc
// NSMutableArray *arr = [NSMutableArray arrayWithCapacity:arrayM.count];
// for (NSDictionary *dict in arrayM) {
// [arr addObject:[XMGVideo videoWithDict:dict]];
// }
// mj NSarray 字典 转 模型
self.videos = [XmgVideo mj_objectArrayWithKeyValuesArray:arrayM];
NSLog(@"%@",self.videos);
}];
// 启动任务
[dataTask resume];
}6 AFN 使用
6.1. AFN 发送 GET 请求 | AFN 下载文件
-(void)touchesBegan10:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
NSDictionary *paramDict = @{
@"username":@"Cehae",
@"password":@"Cehae"
}; //2.发送GET请求/*
AFHTTPSessionManager* manager= [AFHTTPSessionManager manager];
// 1. AFN 发送 GET 请求
[manager GET:@"http://192.168.1.162:8080/JsonServlet/GsonServlet" parameters:paramDict progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//AFN 返回字典，直接字典转模型即可
Person* person=[Person mj_objectWithKeyValues:responseObject];
NSLog(@"person=%@",person);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"%@",error);
}];
//2. AFN 下载文件
NSURL *url = [NSURL URLWithString:@"http://img5.mtime.cn/mg/2019/06/27/104649.48931556_120X90X4.jpg"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLSessionDownloadTask *download = [manager downloadTaskWithRequest:request progress:^(NSProgress * _Nonnull downloadProgress) {
//监听下载进度
/*
downloadProgress.completedUnitCount 已经下载的数据大小
downloadProgress.totalUnitCount); 文件数据的总大小
*/
// NSLog(@"%f",1.0 *downloadProgress.completedUnitCount/downloadProgress.totalUnitCount);
// kvo 监听属性变化
[downloadProgress addObserver:self forKeyPath:@"completedUnitCount" options:kNilOptions context:nil];
} destination:^NSURL * _Nonnull(NSURL * _Nonnull targetPath, NSURLResponse * _Nonnull response) {
NSString *fullPath = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:response.suggestedFilename];
//targetPath 临时文件路径
NSLog(@"targetPath:%@",targetPath); NSLog(@"fullPath:%@",fullPath);
// 真实文件路径，返回真实文件路径即可，会自动拷贝到真实文件路径中
return [NSURL fileURLWithPath:fullPath];
} completionHandler:^(NSURLResponse * _Nonnull response, NSURL * _Nullable filePath, NSError * _Nullable error) { NSLog(@"%@",filePath);
}]; //3.执行Task
[download resume];
}
-(void)observeValueForKeyPath:(NSString *)keyPath ofObject:(NSProgress*)object change:(NSDictionary<NSKeyValueChangeKey,id> *)change context:(void *)context{
NSLog(@"kvo--%f", object.completedUnitCount*1.0/object.totalUnitCount);
}6.2. AFN 上传文件 POST 使用
-(void)touchesBegan11:(NSSet<UITouch *> *)touches11 withEvent:(UIEvent *)event{
AFHTTPSessionManager* manager= [AFHTTPSessionManager manager];
NSString* url=@"http://192.168.2.236:8080/JsonServlet/FileUploadServlet";
/**
<form action="FileUploadServlet" method="post" enctype="multipart/form-data">
用户名 <input type="text" name="name" /> <br /> <br />
照片 <input type="file" name="photo1" /> <br /> <br />
</form>
*/
// 这里相当于用户名
NSDictionary* dict= @{
@"name":@"yyy"
};
//1. OC 封装上传文件方法
// [manager uploadTaskWithRequest:<#(nonnull NSURLRequest *)#> fromData:<#(nullable NSData *)#> progress:<#^(NSProgress * _Nonnull uploadProgress)uploadProgressBlock#> completionHandler:<#^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error)completionHandler#>]
// 2. OC 模拟表单方式上传文件
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"];
[manager POST:url parameters:dict
constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
UIImage* image= [UIImage imageNamed:@"setting_about_pic"];
NSData* imageData= UIImagePNGRepresentation(image);
// 这里 设置 type
[formData appendPartWithFileData:imageData name:@"file" fileName:@"setting_about_pic.png" mimeType:@"image/png"];
// 上传本地文件，单做 application/octet-stream 流处理即可，不用管图片类型
NSURL* url=[NSURL fileURLWithPath:@"/Users/denganzhi/Desktop/ios开发.txt"];
// [formData appendPartWithFileURL:url name:@"file" fileName:@"wwww" mimeType:@"application/octet-stream" error:nil];
[formData appendPartWithFileURL:url name:@"file" error:nil];
} progress:^(NSProgress * _Nonnull uploadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"suc");
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"%@",error);
}];
}6.3. AFN序列化:
AFN自动把json 转化为oc 对象默认
如果是xml: manager.requestSerializer= [AFXMLParserResponseSerializer serializer];
如果不是xml、json :
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
// 自己添加 执行类型
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"];
6.4. 网络监测： 可以用苹果提供demo ，也可以用AFN
-(void)afn
{
//1.创建网络监听管理者
AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager];
/*
AFNetworkReachabilityStatusUnknown = 未知
AFNetworkReachabilityStatusNotReachable = 没有联网
AFNetworkReachabilityStatusReachableViaWWAN = 3G
AFNetworkReachabilityStatusReachableViaWiFi = wifi
*/
[manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
switch (status) {
case AFNetworkReachabilityStatusUnknown:
NSLog(@"未知");
break;
case AFNetworkReachabilityStatusNotReachable:
NSLog(@" 没有联网");
break;
case AFNetworkReachabilityStatusReachableViaWWAN:
NSLog(@"3G");
break;
case AFNetworkReachabilityStatusReachableViaWiFi:
NSLog(@"wifi");
break;
default:
break;
}
}];
[manager startMonitoring];
}7. UIWevView 使用
1.UIWebView 使用： 案例，前进、后退功能
#import "ViewController.h"
@interface ViewController ()<UIWebViewDelegate>
@property (weak, nonatomic) IBOutlet UIWebView *myWebView;
@property (weak, nonatomic) IBOutlet UIBarButtonItem *goBackBtn;
@property (weak, nonatomic) IBOutlet UIBarButtonItem *foWard;
@end
@implementation ViewController
- (IBAction)goBack:(id)sender {
[self.myWebView goBack];
}
- (IBAction)forWard:(id)sender {
[self.myWebView goForward];
}
- (IBAction)reload:(id)sender {
[self.myWebView reload];
}
- (void)viewDidLoad {
[super viewDidLoad];
NSURLRequest* rq= [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.baidu.com"]];
// NSURL *url = [[NSBundle mainBundle]URLForResource:@"text.html" withExtension:nil];
// [self.myWebView loadRequest:[NSURLRequest requestWithURL:url]];
// https://www.jianshu.com/p/f328f4ae397f
//添加 网页 UIDataDetectorTypeAll检测电话、网址和邮箱
self.webView.dataDetectorTypes = UIDataDetectorTypeAll;
[self.myWebView loadRequest:rq];
self.myWebView.delegate= self;
// 网页自动适应webview
self.myWebView.scalesPageToFit = YES;
}
//1.开始加载的时候调用
-(void)webViewDidStartLoad:(UIWebView *)webView
{
NSLog(@"webViewDidStartLoad");
}
//加载完成
-(void)webViewDidFinishLoad:(UIWebView *)webView
{
NSLog(@"webViewDidFinishLoad");
// 设置是否可以前进、后退按钮
self.goBackBtn.enabled = self.myWebView.canGoBack;
self.foWard.enabled = self.myWebView.canGoForward;
NSString* str= [self.myWebView stringByEvaluatingJavaScriptFromString:@"sum();"];
NSLog(@"sum=%@",str);
}
//加载失败
-(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
NSLog(@"didFailLoadWithError");
}
//
//每次加载请求的时候会先带哟, 请求拦截
-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
NSLog(@"=-----%@",request.URL.absoluteString);
if ([request.URL.absoluteString containsString:@"life"]) {
return NO;
}
return YES;
}
@end效果图：
7.2. oc 与js 的互相调用：
7.2.1 oc 对js 调用：
//加载完成 , 直接 调用js 中方法即可
-(void)webViewDidFinishLoad:(UIWebView *)webView
{
NSString* str= [self.myWebView stringByEvaluatingJavaScriptFromString:@"sum();"];
}
js 对oc 调用:
//js 每次加载请求的时候 该代理 方法会回调, 请求拦截，获取拦截js 中协议 ，解析，调用oc 即可
-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{}
text.html:
<html>
<!-- 网页的描述信息 -->
<head>
<meta charset="UTF8">
<title>123</title>
<script>
function show()
{
alert(document.title);
}
// 这里是 js 调用 oc
function repost()

// 这里不能用 xmg://callWithNumber:andContent:?10086&1122333
// 这里不能用： 会报错
location.href = "xmg://callWithNumber_andContent_?10086&1122333";
