关于 ios:UIImagePickerController – 将图片裁剪为正方形(纵向)

UIImagePickerController - crops picture to square (in portrait)

我正在使用 UIImagePickerController 来拍摄和编辑图片。它在横向工作正常，但在纵向它将图片裁剪成正方形(不允许像横向一样缩小图像以完全适合方形裁剪字段。有什么想法吗？

代码：

-(IBAction)initCamera:(id)sender{

//Init imagePicker instance
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
[imagePicker setDelegate:self];

[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setShowsCameraControls:YES];
[imagePicker setAllowsEditing:YES];

[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];
}

查看 GKImagePicker 库，它允许设置您的自定义图像裁剪区域，如下所示：

self.imagePicker = [[GKImagePicker alloc] init];
self.imagePicker.cropSize = CGSizeMake(320, 90);
self.imagePicker.delegate = self;

[self presentModalViewController:self.imagePicker.imagePickerController animated:YES];
