In stead of messing with UIAlertView, you should use a custom presented (or a modal) view. Apple also doesn't like you to mess up with UIAlertView.

So, my (and also the best) suggestion for you is to go with a custom presented (or a modal) view which is also a correct approach in your case also.

试试这个代码

  UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Enter Student Name"
                                                message:@""
                                               delegate:self
                                      cancelButtonTitle:@"Cancel"
                                      otherButtonTitles:@"Save",@"Save & Add",nil];

alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];



-(void)willPresentAlertView:(UIAlertView *)alertView {

if ([[[UIDevice currentDevice] systemVersion] floatValue] <7) 

   {
    [alertView setFrame:CGRectMake(17, 30, 286, 280)];
    NSArray *subviewArray = [alertView subviews];
    UILabel *message = (UILabel *)[subviewArray objectAtIndex:2];
    [message setFrame:CGRectMake(10, 46, 260, 20)];
    UIButton *cancelbutton = (UIButton *)[subviewArray objectAtIndex:3];
    [cancelbutton setFrame:CGRectMake(10, 125, 260, 42)];
    UIButton *savebutton = (UIButton *)[subviewArray objectAtIndex:4];
    [savebutton setFrame:CGRectMake(10, 170, 260, 42)];
    UIButton *saveAddbutton = (UIButton *)[subviewArray objectAtIndex:5];
    [saveAddbutton setFrame:CGRectMake(10, 220, 260, 42)];
    UITextField *textfield = (UITextField *)[subviewArray objectAtIndex:6];
    [textfield setFrame:CGRectMake(10, 80, 266, 50)];
    UITextField *placeTF = (UITextField *)[subviewArray objectAtIndex:7];
    [placeTF setFrame:CGRectMake(15, 70, 256, 50)];
   }

}

    [searchBT setFrame:CGRectMake(10, 220, 260, 42)];
    UITextField *plateTF = (UITextField *)[subviewArray objectAtIndex:6];
    [plateTF setFrame:CGRectMake(10, 80, 266, 50)];
    UITextField *placeTF = (UITextField *)[subviewArray objectAtIndex:7];
    [placeTF setFrame:CGRectMake(15, 70, 256, 50)];

我也在这里尝试过，似乎 UIAlertView 中的 3 个或更多按钮的样式“UIAlertViewStylePlainTextInput”不适合。

您的问题似乎与此直接相关：
iOS5：有人设法用三个按钮和文本字段（UIAlertViewStylePlainTextInput）修复 UIAlertView？

不建议弄乱 UIAlertView 的视图层次结构（因为某些状态的 App Store 拒绝）
参考：如何在 UIAlertView 中向下移动按钮

您可以创建自己的自定义警报视图：http:
//iosdevtricks.blogspot.in/2013/04/creating-custom-alert-view-for-iphone.html

或使用预制的，例如：
https ://github.com/TomSwift/TSAlertView

如果您仍然想冒险，请按照 Kalpesh 的建议（但我不会推荐）

你做错了什么是你试图自定义 UIAlertView 并将子视图放入其中。苹果通常不喜欢并禁止这种方法。您可以尝试执行以下操作：

  1. 您可以尝试像这样的自定义警报视图“复制”

  2. 编写您自己的警报视图“复制”，以满足您的需求，并且在 iOS6/7 上都可以正常工作。
