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];
