标题: ios - 图像的裁剪选项

我想从相册中选择图片并用相机拍摄。它的代码运行良好，但我只需要选择部分图像意味着裁剪图像集我的 imageView。

-(IBAction)chooseAlbumid)sender
{
    imagePicker=[[UIImagePickerController alloc]init];
    imagePicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
    imagePicker.delegate=self;
    [self presentViewController:imagePicker animated:YES completion:nil];
}

-(IBAction)takePictureid)sender
{
    imagePicker=[[UIImagePickerController alloc]init];
    imagePicker.sourceType=UIImagePickerControllerSourceTypeCamera;
    imagePicker.delegate = self;

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

-(void)imagePickerControllerUIImagePickerController*)picker didFinishPickingMediaWithInfoNSDictionary*)info
{
     profileImageView.image=[info objectForKey:UIImagePickerControllerOriginalImage];

    [self dismissViewControllerAnimated:YES completion:nil];
}

Best Answer-推荐答案

开启编辑模式

imagePicker.allowsEditing = YES;

然后在您的委托(delegate)方法中使用 UIImagePickerControllerEditedImage 键

-(void)imagePickerControllerUIImagePickerController*)picker didFinishPickingMediaWithInfoNSDictionary*)info {
    profileImageView.image=[info objectForKey:UIImagePickerControllerEditedImage];
    [self dismissViewControllerAnimated:YES completion:nil];
}
