在事件处理程序中获取UIButton的标题

Question

我创建一个按钮并将标题设置为"单击此处".当我按下该按钮时,我想获得该按钮标题并记录下来.这是我的代码,我哪里错了？

-(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

你的displayvalue:方法应该是这样的:

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

(请查看XCode中的文档,它会给你正确的答案.)

Answer 2

-(void)displayvalue:(id)sender 
{
    UIButton *resultebutton= (UIButton*)sender;
    NSLog(@"The button title is %@ ", resultebutton.titleLabel.text);
}
