您好，希望这是一个容易解决的问题。
我想做的是在按钮操作上有一个选择器，该选择器用要播放的电影的fileName调用我的其他方法。如果我将文件名移回该方法，它将可以正常工作。
我认为我绊脚石是将选择器添加到Button的正确方法。任何意见/建议或建议，将不胜感激。
提前致谢。
//The Button
infobuttonTwo = [UIButton buttonWithType:UIButtonTypeRoundedRect];
infobuttonTwo.frame = CGRectMake(405, 204, 49, 58);
[infobuttonTwo addTarget:self
action:@selector(buttonInfo:) withObject:@"VTS_02_1"
forControlEvents:UIControlEventTouchUpInside];
//The Method It's calling
-(void)buttonInfo:(NSString *) fileName {
//The Error it's showing.

最佳答案
好吧，您的问题是addTarget:action:withObject:forControlEvents:不是UIControl上存在的方法。您需要找到其他方式来跟踪对象值，无论是在ivar，某些中间数据源还是其他方式中。
前段时间有一个similar question，其中包含一些建议。
