快速集成图片浏览器快速集成图片浏览器->MJPhotoBrowser的使用

Posted 2020-06-28 高晓牛

介绍：

    一个比较完整的图片浏览器，高仿了新浪微博的图片浏览效果，功能包括：下载浏览互联网图片，点击缩略图全屏显示图片、当加载较大图片时会出现圆形进度条，滑动浏览所有图片、保存图片到本地相册、GIF图片播放等。而且仅需几行代码就能添加图片浏览器功能。

使用:

        
        for (int i = 0; i<3; i++) {
            UIImageView *img = [[UIImageView alloc]init];
            img.tag = i;
            //单击 添加手势
            UITapGestureRecognizer *singleTapGestureRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapPhoto:)];
            [singleTapGestureRecognizer setNumberOfTapsRequired:1];
            [img addGestureRecognizer:singleTapGestureRecognizer];
//这一行很重要  imageview默认不能进行交互
            img.userInteractionEnabled = YES;
            [img setContentMode:UIViewContentModeScaleAspectFill];
            img.clipsToBounds = YES;
            [CDUtils displayIconImageWithUrl:model.photos[i] imageView:img];
            
            img.frame = CGRectMake((([UIScreen mainScreen].bounds.size.width-2)/3+1)*i, 0, ([UIScreen mainScreen].bounds.size.width-2)/3,([UIScreen mainScreen].bounds.size.width-2)/3);
            [self.imagePicView addSubview:img];
        }

/**
 *  监听图片的点击
 */
- (void)tapPhoto:(UITapGestureRecognizer *)recognizer
{
    //1.创建图片浏览器
    MJPhotoBrowser *brower = [[MJPhotoBrowser alloc] init];
    
    //2.告诉图片浏览器显示所有的图片
    NSMutableArray *photos = [NSMutableArray array];
    for (int i = 0 ; i < self.picAry.count; i++) {
        //传递数据给浏览器
        MJPhoto *photo = [[MJPhoto alloc] init];
        photo.url = [NSURL URLWithString:self.picAry[i]];
        NSLog(@"%@",photo.url);
        photo.srcImageView = (UIImageView *)recognizer.view; //设置来源哪一个UIImageView
        [photos addObject:photo];
    }
    brower.photos = photos;
    
    //3.设置默认显示的图片索引
    brower.currentPhotoIndex = recognizer.view.tag;
    
    //4.显示浏览器
    [brower show];
}

要包含这两个头文件:

#import "MJPhoto.h"

#import "MJPhotoBrowser.h"
