所以这就是我所拥有的。我创建了一个按钮并将其设置为一个动作,但每次我单击该按钮时都会使程序崩溃。为什么我的按钮不起作用?提前致谢。

UIButton *currentGamesButton = [UIButton buttonWithType:UIButtonTypeCustom];
currentGamesButton.frame = CGRectMake(124,18,72,65);
[currentGamesButton addTarget:self
                       action:@selector(goToCurrentGamesViewController:)
             forControlEvents:UIControlEventTouchDown];
UIImage *currentGamesPNG = [UIImage imageNamed:@"CurrentGamesHighlightedState.png"];
[currentGamesButton setBackgroundImage:currentGamesPNG forState:UIControlStateNormal];
[self.view addSubview:currentGamesButton];

如果 for 的方法goToCurrentGamesViewController不带参数,请更改此行:

[currentGamesButton addTarget:self
                   action:@selector(goToCurrentGamesViewController:)

到:

[currentGamesButton addTarget:self
                   action:@selector(goToCurrentGamesViewController)

:(从选择器中的方法中删除冒号)
