我是新的iPhone开发人员.我收到了这个错误.

请帮我

我有一个UILabel,我需要在其中显示两个不同颜色的字符串:下面是我的代码:

NSMutableAttributedString *text = [[NSMutableAttributedString alloc] initWithAttributedString: lbl_question.attributedText];

[text addAttribute: NSForegroundColorAttributeName value: [UIColor colorWithRed:52.0f/255.0f green:104.0f/255.0f blue:165.0f/255.0f alpha:1.0f] range: NSMakeRange(0,[result integerValue]+1)];

[text addAttribute: NSForegroundColorAttributeName value: [UIColor colorWithRed:75.0f/255.0f green:75.0f/255.0f blue:75.0f/255.0f alpha:2.0f] range: NSMakeRange([result integerValue]+1,[strq length])];
[lbl_question setAttributedText: text];

在iOS 6中它可以正常工作,但在ios 5和早期版本中,这两个字符串每次都被忽略了.我也希望根据文字和字体获得宽度.根据文字增加高度.

我相信必须有解决方案......请帮我解决这个问题....

我想在uitableview中创建加载更多数据,比如在当时显示活动指示器并再次加载更多数据.我在ios开发中使用asihttp请求进行Web服务.所以请帮帮我......
