Iphone 如何从我的相机中保存裁剪的图像？

在我的应用程序中，我使用相机功能，我使用overlayview来拍摄每一件事情

问题是，在保存图像时，我不想保存整个图像，我只想保存覆盖视图中显示的图片

请查看下面两个屏幕之间的差异

1）以下是我在叠加视图中显示的内容：

2）以下是我得到的信息：

谢谢！提前

创建UIImagePickerController的对象

CGRect rect = self.overlayimage.frame;

UIGraphicsBeginImageContext(CGSizeMake(self.overlayimage.frame.size.width, self.overlayimage.frame.size.height));
// This is where we resize captured image
[(UIImage *)[info objectForKey:UIImagePickerControllerOriginalImage] drawInRect:rect];


captureimage.image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

imagePickerController.allowsEditing = YES;

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

并在UIImagePickerController的委托方法中获取裁剪后的图像

imagePickerController.allowsEditing = YES;

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

UIImage*croppedImg=[info objectForKey:@“UIImagePickerControllerEditedImage”]；
