从相机胶卷装入的照片在纵向模式下过度拉伸

我在使用相机胶卷中的图像进行UIView时遇到了问题 .

当我选择以纵向模式拍摄的照片时，视图总是将图像拉得太高，但是当我旋转设备时，图像被拉伸得很好 .

- (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];

任何帮助表示赞赏 .

    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];
    }
}

    你的代码看起来很好，除了它泄漏，你有太多的开口括号和没有关闭括号 .

    您可能希望它看起来像这样：

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

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

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

    UIViewContentModeScaleAspectFill 不应该拉伸图像 . 它应该剪辑它 . 也许 UIViewContentModeScaleAspectFit 正是您要找的？
