您好！第一次点击小图弹出正常，点击图片dismiss之后再次点击小图，小图也会出现在屏幕上，点击大图使其dismiss没有了动画效果。 代码如下： `_taskImgThumbnail = [[UIImageView alloc] init]; //先截取原图正方形图片，再转化为200宽缩略图，转化为50的话图片模糊 _taskImgThumbnail.image = [self thumbnailWithImage:[self thumbnailCenterImage:[UIImage imageNamed:@"IMG_0065"] centerInSize:CGSizeMake([UIImage imageNamed:@"IMG_0065"].size.width, [UIImage imageNamed:@"IMG_0065"].size.width)] size:CGSizeMake(200,200)]; [self.view addSubview:_taskImgThumbnail]; [_taskImgThumbnail mas_makeConstraints:^(MASConstraintMaker *make) { make.centerX.equalTo(taskImgTip); make.top.equalTo(taskImgTip.bottom).offset(7*WIDTHRATE); make.size.equalTo(CGSizeMake(50*WIDTHRATE, 50*WIDTHRATE)); }];...
