获取发送按钮tag/name/ID

在下面方法中获取发送按钮的 Tag/Name/ID

-(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info
{
// I Want to get the sender button reference here
}

根据tag取控件，使用

id control = [self.view viewWithTag:yourTag];

1.创建按钮的时候，给到按钮一个tag值，button.tag=111;
2.在要得到按钮对象的地方获取按钮 UIButton *bu=(UIButton *)[self.view viewWithTag:111];
