I create a button and set title as "Click here". When I press that button I want to get that button title and log it. Here's my code, where am I going wrong?

-(void)clicketbutton {
    UIButton *mybutton = [UIButton buttonWithType:UIButtonTypeCustom];

    [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.
}

推荐答案

你的 displayvalue: 方法应该是这样的:

Your displayvalue: method should look something like this:

-(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.)
