在我的应用程序中，我添加了推送通知服务，一切正常。 需要在 App 未处于事件或后台模式时处理通知。
我为此添加了如下代码。在方法中
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeSound];
NSDictionary *RemoteNoti =[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (RemoteNoti) {
//your methods to process notification
}
return YES;
}
例如，我收到了三个通知 当应用程序未在后台或前台运行并且我点击通知时，它只会给我点击通知的详细信息。
它只提供点击通知的详细信息是正确的行为吗？或者应该有所有三个通知的详细信息 NSDictionary *RemoteNoti =[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
如果我遗漏了什么，请提出建议。
最佳答案
是的，这是正确的行为。您只会收到一个您选择的通知。
In dictionary containing the payload of the remote notification. > - alert: Either a string for the alert message or a dictionary with two keys: body and show-view. > - badge: A number indicating the quantity of data items to download from the provider. This number is to be displayed on the app icon. The absence of a badge property indicates that any number currently badging the icon should be removed. > - sound: The name of a sound file in the app bundle to play as an alert sound. If “default” is specified, the default sound should be played.
