我正在使用 UIImagePickerController 拍摄和编辑照片。它在风景中工作正常，但在肖像中它会将图片裁剪成正方形(不允许像在风景中那样缩小图像以完全适合方形裁剪区域。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];
}
最佳答案
查看 GKImagePicker库，它允许设置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];
