IOS 类似驾考宝典题目切换控件实现
当我们题目切换控件时候，很多时候我们会看下驾考宝典的效果
具体如何实现该效果呢，手势控制及切换view
下面给出具体代码如下
- 1、内容控件UIView。JJDQContentView.h
#import "BaseView.h"
@interface JJDQContentView : BaseView
@property (nonatomic, strong) NSString *title;
@property (nonatomic, strong) NSString *content;
@property (nonatomic, assign) NSInteger contentTag;
@end
- 2、内容控件UIView。JJDQContentView.m
#import "JJDQContentView.h"
@interface JJDQContentView ()
@property (nonatomic, strong) UILabel *titleLabel;
@property (nonatomic, strong) UILabel *contentLabel;
@end
@implementation JJDQContentView
- (instancetype)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
_titleLabel = [[UILabel alloc] initWithFrame:CGRectZero];
_titleLabel.backgroundColor = [UIColor clearColor];
_titleLabel.textAlignment = NSTextAlignmentCenter;
_titleLabel.font = [UIFont systemFontOfSize:16];
_titleLabel.textColor = [UIColor colorWithHexString:@"555555"];
[self addSubview:_titleLabel];
_contentLabel = [[UILabel alloc] initWithFrame:CGRectZero];
_contentLabel.backgroundColor = [UIColor clearColor];
_contentLabel.textAlignment = NSTextAlignmentCenter;
_contentLabel.font = [UIFont systemFontOfSize:14];
_contentLabel.textColor = [UIColor colorWithHexString:@"7a7a7a"];
_contentLabel.numberOfLines = 0;
_contentLabel.lineBreakMode = NSLineBreakByCharWrapping;
[self addSubview:_contentLabel];
}
return self;
}
- (void)layoutSubviews {
[super layoutSubviews];
self.titleLabel.frame = CGRectMake(30.0, 50.0, CGRectGetWidth(self.bounds) - 60.0, 50.0);
self.contentLabel.frame = CGRectMake(30.0, 0.0, CGRectGetWidth(self.bounds) - 60.0, CGRectGetHeight(self.bounds) - CGRectGetMaxY(self.titleLabel.frame));
}
- (void)setTitle:(NSString *)title {
_title = title;
self.titleLabel.text = [NSString stringWithFormat:@"%@",title];
[self setNeedsLayout];
}
- (void)setContent:(NSString *)content {
_content = content;
self.contentLabel.text = [NSString stringWithFormat:@"%@",content];
[self setNeedsLayout];
}
- (void)dealloc {
}
@end
- 3、实现切换及手势控制的UIView。JJDQSwitchView.h
#import "JJDBaseView.h"
@interface JJDQSwitchView : JJDBaseView
@end
- 4、实现切换及手势控制的UIView。JJDQSwitchView.m
#import "JJDQSwitchView.h"
#import "JJDQContentView.h"
@interface JJDQSwitchView ()
@property (nonatomic, strong) JJDQContentView *leftView;
@property (nonatomic, strong) JJDQContentView *centerView;
@property (nonatomic, strong) JJDQContentView *rightView;
@property (nonatomic, assign) CGPoint startPoint;
@property (nonatomic, assign) NSInteger contentTag;
@property (nonatomic, strong) NSMutableArray *qLists;
@end
@implementation JJDQSwitchView

break;

self.rightView = view;
view.contentTag = 1;
view.title = [NSString stringWithFormat:@"第%ld页",(long)self.contentTag + 1];
break;
default:
break;
}
}
