iphone - 从相机胶卷加载的图片在纵向模式下过于拉伸(stretch)

Question

我在使用 UIView 时遇到问题，它正在从相机胶卷中获取图像。

当我选择一张在肖像模式下拍摄的照片时， View 总是将图片拉伸(stretch)得太高，但当我旋转我的设备时，图片拉伸(stretch)得很好。

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    if(info){
        {
            [artView removeFromSuperview];
            artView = nil;
            artView = [[UIImageView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];

            artView.image = [info objectForKey:UIImagePickerControllerOriginalImage];
            artView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
            artView.contentMode = UIViewContentModeScaleAspectFill;

[self.contentView addSubview:artView];

感谢任何帮助。

如果其他人仍然遇到此问题，请尝试在 contentMode 之后设置图像。

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    if (info) {
        [artView removeFromSuperview];
        artView = [[UIImageView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];

        artView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
        artView.contentMode = UIViewContentModeScaleAspectFill;
        artView.image = [info objectForKey:UIImagePickerControllerOriginalImage];

        [self.contentView addSubview:artView];
        [artView release];
    }
}
