Please try this...

Add this code to appdelegate.m => didFinishLaunchingWithOptions

<pre><code>if ([launchOptions valueForKey:@"UIApplicationLaunchOptionsRemoteNotificationKey"]) {

 [self application:application didReceiveRemoteNotification:launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]];

}
</code></pre>

blocks|key|2442059|text|在ios7中，我们使用下面的委托方法来处理应用程序处于后台或未运行时的推送通知|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2442060|-+(void)application:(UIApplication+*)application+didReceiveRemoteNotification:(NSDictionary+*)userInfo+fetchCompletionHandler:(void+(%5E)(UIBackgroundFetchResult+result))handler+|code-block|syntax|javascript|2442061|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

From ios7 we have the below delegate method to handle the push notification when the app is in back ground or not running

<pre><code>- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler 
</code></pre>

blocks|key|2357983|text|我不完全理解您的要求，但您可以使用应用程序委托中的函数来处理正在推送的内容|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2357984|-+(void)application:(UIApplication*)application+didReceiveRemoteNotification:+
(NSDictionary*)userInfo
{
NSLog(@"Received+notification:+%25@",+userInfo);
[self+addMessageFromRemoteNotification:userInfo+updateUI:YES];
}|code-block|syntax|javascript|2357985|现在，您可以将该数据添加到核心数据或sqlite。这可能与你的问题无关，但根据你在问题中提出的问题，这是我能给出的最好的答案。|2357986|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

I don't totally understand what your asking but you can do stuff with what is being being push with a function in the app delegate

<pre><code>- (void)application:(UIApplication*)application didReceiveRemoteNotification: 
(NSDictionary*)userInfo
{
NSLog(@"Received notification: %@", userInfo);
[self addMessageFromRemoteNotification:userInfo updateUI:YES];
}
</code></pre>

Now you can add that data to core data or sqlite. This may not be relevant to your question but it's the best I can give based on what you've asked in your question.

blocks|key|1412740|text|请看我对上面答案的评论。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1412741|以下是苹果的文档：|1412742|1412743|如果推送通知到达时应用程序未运行，则此方法将启动应用程序，并在启动选项字典中提供相应的信息。应用程序不会调用此方法来处理推送通知。相反，您的应用程序:willFinishLaunchingWithOptions:或application:didFinishLaunchingWithOptions:方法的实现需要获取推送通知有效负载数据并做出适当响应。|blockquote|1412744|1412745|1412746|所以你需要实现：|1412747|-+(void)application:(UIApplication*)application+didReceiveRemoteNotification:+

See my comment on the above answer.

Here is Apple's doc:

<blockquote>
 If the app is not running when a push notification arrives, the method
 launches the app and provides the appropriate information in the
 launch options dictionary. The app does not call this method to handle
 that push notification. Instead, your implementation of the
 application:willFinishLaunchingWithOptions: or
 application:didFinishLaunchingWithOptions: method needs to get the
 push notification payload data and respond appropriately.
</blockquote>

So you need to implement:

<pre><code>- (void)application:(UIApplication*)application didReceiveRemoteNotification: 
(NSDictionary*)userInfo
</code></pre>

As well as handling the launchOptions in:

<pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
</code></pre>

I want to get data from push notification message. I successfully get the data when app is on foreground and in background. but I am unable to get data when app is quit and user press view button on push notification. I write the code in application did finish launching. This code cause the app crash when pressing on View button of push notification message. If I comment the code then app doesn't crash. Kindly help me to fetch data from push notification when app is quit and user press view button on push notification. I'll really appreciate that.

<pre><code>if(launchOptions != nil){
 NSDictionary *tmpDic = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
 if (tmpDic!=nil) {
 pushedMessage=[NSString stringWithFormat:@"%@",[[tmpDic objectForKey:@"aps"] objectForKey:@"alert"]];
 pushedCountry=[NSString stringWithFormat:@"%@",[tmpDic objectForKey:@"country"]];
 [self saveToDatabase];
 }
 }
</code></pre>

我想从推送通知消息中获取数据。app在前台和后台都能成功获取数据。但我无法获得数据时，应用程序是退出和用户按下查看按钮的推送通知。我在应用程序中写的代码确实完成了启动。此代码导致应用程序在按下推送通知消息的查看按钮时崩溃。如果我注释代码，那么应用程序就不会崩溃。请帮助我从推送通知获取数据时，应用程序是退出和用户按下查看按钮的推送通知。我真的很感激。if(launchOptions != nil){
