Loop--Banner循环自动滚动视图

Loop

无限滚动视图, 适用于Banner的滚动
项目地址:https://github.com/whde/Loop

使用说明:

• 1.下载项目,打开项目
• 2.command+B打包Loop.Framework
• 3.将Loop.Framework导入到自己的项目中

• 4.导入头文件

#import <Loop/CLoopScrollView.h>
#import <Loop/CLoopCell.h>

• 5.创建一个继承于CLoopCell的Cell
• 6.实现CLoopCell中的两个方法
  例如简单的Banner:

#import "CBannerLoopCell.h"
#import "CTopModel.h"
@interface CBannerLoopCell() {
    UIImageView *imgView;
}
@end

@implementation CBannerLoopCell

- (id)initWith:(id)model withScrollViewFrame:(CGRect)rect{
    self = [super initWith:model withScrollViewFrame:rect];
    imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0,
                                                            0,
                                                            rect.size.width,
                                                            rect.size.height)];
    imgView.contentMode = UIViewContentModeScaleAspectFill;
    imgView.clipsToBounds = YES;
    [self addSubview:imgView];
    [self reloadWith:model];
    return self;
}

- (void)reloadWith:(id)model{
    [super reloadWith:model];
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@", ((CTopModel *)model).imageUrl]];
    [imgView setImageWithURL:url placeholderImage:nil];
}

@end

• 7.创建LoopScrollView并addSubView

_topView = [[CLoopScrollView alloc] initWithFrame:CGRectMake(0, 0, ScreenWidth, ScreenWidth*0.5)
                                  scrollDirection:LoopScrollViewScrollDirectionLandscape 
                                           models:_mainModel.topArray
                                      ofCellClass:[CBannerLoopCell class]];
[_topView setRollingDelayTime:4.0];
[_topView setSquare:0];
[header addSubview:_topView];
__block UILabel *weekTopPage = _topPage;
[_topView setScrollBlock:^(CLoopScrollView *loopScrollView, NSInteger index, id model) {
    NSLog(@"%d/%lu", (int)index+1, (unsigned long)[loopScrollView.models count]);
}];
__block CViewController *weekSelf = self;
[_topView setSelectBlock:^(CLoopScrollView *loopScrollView, CLoopCell *view, NSInteger index, id model) {
    [weekSelf doSomething]
}];
