Question

从图库或相机中挑选图像后 - 需要启用旋转，翻转编辑我该如何使用它。这是我的代码：

-(void)photofromCamera
{

    @try
    {
         NSLog(@"2");
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.allowsEditing = YES;
        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
        [self presentViewController:picker animated:YES completion:nil];

    }
    @catch (NSException *exception)
    {

        [self showAlert:@"Camera is not available"];
    }

}



-(void)photofromGallery
{

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentViewController:picker animated:YES completion:NULL];
}

所以在委托方法之后：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [self.imageDeletionButton setHidden:NO];
    UIImage *chosenImage = [info valueForKey:UIImagePickerControllerEditedImage];
     self.PostImageView.image = chosenImage;
     [picker dismissViewControllerAnimated:YES completion:nil];
}

好像现在，如果我从画廊选择任何图像，相机 - 我需要显示裁剪，翻转，旋转。请帮助我如何实现。

提前致谢!!!

您可以使用基于swift的框架IGRPhotoTweaks来旋转，翻转和裁剪图像。您可以查看http://docs.nwjs.io/en/latest/References/Window/#winreloadignoringcache获取git和对于cocoapods https://github.com/IGRSoft/IGRPhotoTweaks。在框架cropAction()和changedAngel(value: radians)中，您需要尝试两种方法来实现您的要求。
