我正在使用此代码来制作自定义相机裁剪：

UIImagePickerController 编辑视图圆圈叠加

这在相机胶卷中效果很好，但不能拍照

如果我更改 [navigationController.viewControllers count] == 3 --> [navigationController.viewControllers count] == 1 也适用于相机，但不适用于下一个视图（您接受使用照片的预览视图）

谁来帮帮我？？

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex == 0) {
    NSLog(@"Camara");
    UIImagePickerController * imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.allowsEditing = YES;
    imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePicker.delegate = self;
    self.isCamera = YES;

    [self presentViewController:imagePicker animated:YES completion:nil];

}else{
    NSLog(@"Carrete");
    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc]init];
    imagePickerController.allowsEditing = YES;
    imagePickerController.delegate = self;
    imagePickerController.sourceType =  UIImagePickerControllerSourceTypePhotoLibrary;
    self.isCamera = NO;
    [self presentViewController:imagePickerController animated:YES completion:nil];
}

}
