objective-c - 图像被拉伸(stretch)

Question

我有一张图片(从我们的服务器获取)，我想将它放入 UIImageView 中。图片为 373x500。 UIImageView 是 443x290 并且 View 正在拉伸(stretch)它。

UIImageView *myImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 
                                                                         0, 
                                                                         500, 
                                                                         300)];

myImageView.image = [UIImage imageWithData:photoData];
myImageView.backgroundColor = [UIColor viewBackgroundColor];
myImageView.contentMode = UIViewContentModeScaleAspectFit;

NSLog(@"myImageView.image.size: %@", NSStringFromCGSize(myImageView.image.size));
NSLog(@"myImageView.frame.size: %@", NSStringFromCGSize(myImageView.frame.size));

[wrapperView addSubview:myImageView];

日志读取:

2012-05-09 11:32:52.621[89145:1a303] myImageView.image.size: {373, 500}
2012-05-09 11:32:52.622[89145:1a303] myImageView.frame.size: {443, 290}

看起来像:

“UIViewContentModeScaleAspectFit”不应该告诉它保持比例而不拉伸(stretch)图像吗？

您还应该在 View 上设置 clipsToBounds = YES。
