<span id="Label3"></p><p><p>Recent projects using the push module, the use of the Penguin Empire <strong>carrier pigeon push service</strong> , about the specific how to push the certificate, how to set up, I will not repeat, as the development of the document has been said very clearly, and secondly in the online search words can also search a lot; <strong> Here is the main write about the push notification came after the click on this notice how to deal with,</strong> but also to do a note after you finish</p></p><p><p>Here in my project to achieve the effect is to click on the <em><strong>notification bar push message, the corresponding page into the application</strong></em> , the default effect is to click the push message, will go directly to the app, <em><strong>if the app does not start, will launch the app into the first page</strong></em> <em><strong>, if the app has started, Just click Home back into the background, it will return to the application, and the application before the interface, which is still the interface;</strong></em></p></p><p><p>1. <strong>If the app does not start</strong></p></p><p><p>You can use the</p></p> <blockquote> <blockquote> <p>-(BOOL) application: (uiapplication*) application didfinishlaunchingwithoptions: (nsdictionary*) launchOptions</p> </blockquote> </blockquote><p><p>method to determine whether to click on the icon to launch the app or click the push message to launch the app, <strong>if it is clicked push launch application, the above method of the launchoptions will not be nil, can be judged by nil;</strong></p></p> <blockquote> <blockquote> <p>if (<strong>launchoptions</strong>) {</p> <p>nsdictionary* <strong>remotenotification</strong> = [launchoptionsobjectforkey: uiapplicationlaunchoptionsremotenotificationkey];</p> <p>If (remotenotification) {</p> <p>NSLog (@ "push over the message is%@", remotenotification);</p> <p>Click Push notification to enter the specified interface (this is definitely the equivalent of entering from the Background)</p> <p>[self <strong>gotomssageviewcontrollerwith:</strong>remotenotification];//how to enter the corresponding page</p> <p>}</p> <p>}</p> </blockquote> </blockquote><p><p>The returned dictionary <strong>remotenotification</strong> is the <strong>push message body</strong> , where you can print to view and then determine if <strong>you clicked the push message to launch the app, Gotomssageviewcontrollerwith:</strong> The method inside the code to enter their own message corresponding to the page (again)</p></p><p><p>2. <strong>If the app is started, hang it in the background</strong></p></p><p><p>In this case, clicking the push message into the app will call</p></p> <blockquote> <blockquote> <p>-(void) application: (uiapplication*) application didreceiveremotenotification: (nsdictionary*) userInfo</p> </blockquote> </blockquote><p><p><strong>UserInfo is the subject of the message being Pushed.</strong></p></p><p><p>In this method, you can make your own code operation to enter the message corresponding page</p></p><p><p>3. <strong>If the app is running in the foreground when the push message arrives</strong></p></p><p><p>This situation still calls 2.
