iphone - 在事件处理程序中获取 UIButton 的标题

Question

我创建了一个按钮并将标题设置为“单击此处”。当我按下那个按钮时，我想得到那个按钮的标题并记录下来。这是我的代码，我哪里出错了？

-(void)clicketbutton {
    UIButton *mybutton = [UIButton buttonWithType:UIButtonTypeCustom];
    [mybutton setTitle:@"Click here"  forState:UIControlStateNormal];
    [mybutton addTarget:self  
       action:@selector(displayvalue:)forControlEvents:UIControlEventTouchUpInside]; 
}

-(void)displayvalue:(id)sender {       
    UIButton *resultebutton= [UIButton buttonWithType:UIButtonTypeCustom];

    resultebutton=sender;// pls clear here.. my question here , it it possible or not. if possible how ?
    NSLog(@" The buttontitile is %@ ", [resultebutton.Title] // here also.
}

Answer 1

您的 displayvalue: 方法应如下所示:

-(void)displayvalue:(id)sender {       
    UIButton *resultButton = (UIButton *)sender;
    NSLog(@" The button's title is %@.",  resultButton.currentTitle);
}

(请查看 XCode 中的文档，它会给您正确的答案。)
