ios - Objective-C 通过绘图裁剪图像

Question

我是 iOS 新手。我想通过从用户那里绘制来裁剪图像。我在谷歌上搜索了一天，但没有得到结果。 谢谢您的回答。

Answer 1

试试这段代码

  UIImagePickerController *picker=[[UIImagePickerController alloc] init];
    picker.delegate = self;
    [picker setAllowsEditing:YES];
    picker.sourceType=UIImagePickerControllerSourceTypeCamera;
    [self presentViewController:picker animated:YES completion:nil];

然后你可以从

中获取裁剪图像

  - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
 {
  UIImage *image = [info valueForKey:UIImagePickerControllerEditedImage];
 picker dismissViewControllerAnimated:YES completion:^{}];

}
