iphone - 重定向 UIAlertView 按钮推送通知
<p><p>我已经阅读了很多关于这个问题的帖子，但没有一个能真正帮助我。这似乎很容易做到，但不知何故我无法弄清楚。</p>
<p>我想在这里做什么？
好吧，我向我的应用程序发送推送通知。一切正常。
我可以在它处于后台、非事件状态甚至应用程序未运行时处理它。
但是另一种状态——前台应用程序——让我头疼。</p>
<p>我有这个正在使用的代码片段。一切都好。
当应用程序在前台运行时，用户会获得 UIAlertview。
但是如何向 View 按钮添加操作？
我的意思是这个特定的 Action :当有人点击查看按钮时，他/她会被重定向到通过推送通知传递的 url。</p>
<p>就像我之前在代码片段中使用的一样(准确地说是这部分):</p>
<pre><code>NSString *notifUrl = ;
NSLog(@"Received Push Url: %@", notifUrl);
</code></pre>
<p>我希望这是有道理的，有人可以帮助我。我迷失了这个......这是与这个主题相关的整个代码片段。</p>
<pre><code>-(void)Redirect:(NSString*)url{
[ openURL:];
NSLog(@"%@",url);
}
/**
* Remote Notification Received while application was open.
*/
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
#if !TARGET_IPHONE_SIMULATOR
NSLog(@"remote notification: %@",);
NSDictionary *apsInfo = ;
NSString *alert = ;
NSLog(@"Received Push Alert: %@", alert);
NSString *sound = ;
NSLog(@"Received Push Sound: %@", sound);
AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
NSString *badge = ;
NSLog(@"Received Push Badge: %@", badge);
application.applicationIconBadgeNumber = [ integerValue];
NSString *notifUrl = ;
NSLog(@"Received Push Url: %@", notifUrl);
// app was already in the foreground
if ( application.applicationState == UIApplicationStateActive ) {
UIAlertView *alertPush = [initWithTitle: @"Message"
message: alert
delegate: self
cancelButtonTitle:@"View"
otherButtonTitles: @"Cancel", nil];
;
;
}
// app is inactive or in the background
else {
;
}
#endif
}
// what to do if user taps the viewbutton in push notification alert view
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if(buttonIndex == 0) {
NSLog(@"View Button has been tapped");
// We need the url that has been passed by the push notification
}
else {
// Do something
}
}
</code></pre></p>

<p><p>只需在 .h 文件中定义您的变量 <code>notifUrl</code> ，以便您也可以在类的其他方法中访问它。然后将 url 存储在该变量中并在 alertview 委托(delegate)方法中使用它。</p>
<pre><code>//Add this in .h file
NSString *notifUrl;
//Add this in .m file
-(void)Redirect:(NSString*)url{
[ openURL:];
NSLog(@"%@",url);
}
/**
* Remote Notification Received while application was open.
*/
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
#if !TARGET_IPHONE_SIMULATOR
NSLog(@"remote notification: %@",);
NSDictionary *apsInfo = ;
NSString *alert = ;
NSLog(@"Received Push Alert: %@", alert);
NSString *sound = ;
NSLog(@"Received Push Sound: %@", sound);
AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
NSString *badge = ;
NSLog(@"Received Push Badge: %@", badge);
application.applicationIconBadgeNumber = [ integerValue];
//Define this variable in .h file so that you can access this in other methods as well
notifUrl = ;
NSLog(@"Received Push Url: %@", notifUrl);
; // this is retain value of notifUrl so that you can use it later
// app was already in the foreground
if ( application.applicationState == UIApplicationStateActive ) {
UIAlertView *alertPush = [initWithTitle: @"Message"
message: alert
delegate: self
cancelButtonTitle:@"View"
otherButtonTitles: @"Cancel", nil];
;
;
}
// app is inactive or in the background
else {
;
}
#endif
}
// what to do if user taps the viewbutton in push notification alert view
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if(buttonIndex == 0) {
NSLog(@"View Button has been tapped");
NSLog(@"Received Push Url: %@", notifUrl);
;
}
else {
// Do something
}
}
