iOS8的UIAlertController标题总是为零 [英] UIAlertController title is always nil with iOS8

问题描述

我有一个问题，因为iOS8和Xcode 6.0.1，我的警报对话框的标题没有出现。所以我将我的UIAlertView更改为UIAlertController，但我遇到了同样的问题...

警报的标题总是为零，显示非常难看，因为我不知道有serparator行。

你知道为什么我有这个吗？

  UIAlertController * alert = [UIAlertController alertControllerWithTitle：@title消息：@messagepreferredStyle：UIAlertControllerStyleAlert]; 
 
 [alert addAction：[UIAlertAction actionWithTitle：@OKstyle：UIAlertActionStyleDefault handler：^（UIAlertAction * action）{
 [self dismissViewControllerAnimated：YES completion：nil]; 
}]]; 
 
 [self presentViewController：alert animated：YES completion：nil]; 
  

但这是结果

< img src =https://i.stack.imgur.com/U31cE.pngalt =没有标题的Alertview>

 （lldb）po alert.title 
 nil 
（lldb）po alert.message 
 message 
  

谢谢。

解决方案

感谢@Myaaoonn解决了我的问题！

UIAlertView标题不显示

我刚刚从我的ViewController中删除了以下方法
类别类及其工作fyn！

   - （void）setTitle：（NSString *）title 
 {
 //我的代码
} 
  

I have a problem since iOS8 and Xcode 6.0.1, the title of my alert dialogs doesn't appear. So I changed my UIAlertView to UIAlertController but I have the same issue...

The title of my alert is always to nil and the displaying is very ugly because I don't have the serparator lines.

Do you know why i have this ?

    UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"title" message:@"message" preferredStyle:UIAlertControllerStyleAlert];

    [alert addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        [self dismissViewControllerAnimated:YES completion:nil];
    }]];

    [self presentViewController:alert animated:YES completion:nil];

But this is the result

(lldb) po alert.title
nil
(lldb) po alert.message
message

Thank you.
