UIButton建立动态变化

Question

我有一个uibutton，我正在将其标题更改为我从webservice收到的数据我已经打印了uibutton当前磁贴和我要显示的标题，但它没有更改按钮标题

NSString *str = [NSString stringWithFormat:@"%@",[[status objectForKey:@"detail"] valueForKey:@"goalDetailText"]];
[goalButton setTitle:str forState:UIControlStateSelected];
NSLog(@"title is %@ and value is %@",goalButton.currentTitle,str);                [goalButton setTitle:str forState:UIControlStateSelected];

控制台是

2013-11-25 12:13:04.666 = sdad [3389:1003] title is Loading ... and value is Learn and practise how to minimize "emotional eating"

但问题是uibutton标题需要时间来改变标题就像一个龙时间，但我已经检查了webservice的值不是null并且它的打印绝对没问题，但是它的设置花费了太多时间。我的项目是在IOS7上。

如果您的按钮状态更改为正常，则在您点按内部后，您需要使用UIControlStateNormal状态作为标题：

[goalButton setTitle:str forState:UIControlStateNormal];
