这是我的代码：
-(void) takePhoto
{
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
//imagePickerController.editing = YES;
imagePickerController.allowsEditing=YES;
imagePickerController.delegate = self;
[self presentViewController:imagePickerController animated:YES completion:NULL];
}
#pragma mark - Image picker delegate methods
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediawithInfo:(NSDictionary *)info {
[picker dismissViewControllerAnimated:NO completion:nil];
[self.Picture setimage:[info objectForKey:UIImagePickerControllerOriginalImage]];
}
我已经执行了代表们
UINavigationControllerDelegate,UIImagePickerControllerDelegate
图像被拍摄,我可以看到移动和缩放框,但是当我移动它时,框返回到初始位置 – 喜欢它反弹.
这是为什么？
解决方法
看起来这是因为您要求UIImagePickerControllerOriginalImage,根据文档返回“由用户选择的原始的未裁剪图像”.
尝试将其更改为UIImagePickerControllerEditedImage.

编辑：实际上,在重新阅读问题几次后,如果问题出现在选择器本身,这可能不会有帮助.
