iOS 自定义相册图片编辑页面

//从相册中选取图片或拍照

- (void)btnActionForEditPortrait:(id) sender {

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];

    picker.delegate = self;

    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    picker.allowsEditing = YES;

    

    [self presentViewController:picker animated:YES completion:NULL];

}

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

    

    _avatar = info[UIImagePickerControllerEditedImage];

    [self saveImage:_avatar WithName:@"userAvatar"];

    //处理完毕，回到个人信息页面

    [picker dismissViewControllerAnimated:YES completion:NULL];

    [_tableView reloadData];

}

以上代码是先选择照片，然后用系统自带的编辑页面进行剪切。如果我们想自定义图片编辑页面怎么办呢？

picker.allowsEditing = NO;

设置为no之后就可以在didFinishPickingMediaWithInfo中切换到自定义图片编辑页面了。
