在UIAlertView上显示UIActionSheet [英] Showing UIActionSheet over UIAlertView

问题描述

对于特定的服务器通知，我应该显示一个UIActionSheet.但是这里的问题是该事件到来的同时，如果任何UIAlertView已经显示在任何视图控制器上，则会使UIActionSheet禁用(在为警报视图按ok之后，我无法在视图控制器上选择任何内容，因为该视图被禁用，因为UIActionSheet).任何人都面临此类问题，有什么解决方案的想法吗?

Anyone faced this kind of problem, Any idea how to solve it?

注意:iPod不会出现相同的问题，因为它不允许在响应UIActionSheet之前单击确定".

推荐答案

获取一个名为AlertAlertView的全局警报视图.现在，当您显示警报视图时，请检查该警报视图，然后显示并分配.像

Take a Global Alert view named it as activeAlertView. Now when you show a alert view please check that alert view and then show and assign. Like

在.h中声明一个属性并对其进行合成

declare a property in .h and synthesize it

@property (nonatomic, retain) UIAlertView *activeAlertView;

然后在尝试显示警报时使用以下代码.

then use the below code when try to show an alert.

if(self.activeAlertView){
    [self.activeAlertView dismissWithClickedButtonIndex:0 animated:YES];
}
UIAlertView *localAlert = [[UIAlertView alloc] initWithTitle:@"Title" message:@"Your message" delegate:nil cancelButtonTitle:@"cancel" otherButtonTitles:nil, nil ];
[localAlert show];
self.activeAlertView = localAlert;
[localAlert release];

这样，您的activeAlertview将保留当前aler视图的引用，并在显示actionSheet之前关闭警报视图.

this way your activeAlertview will keep the current aler view's reference and before show the actionSheet dismiss the alert view.
