要为您的设备注册推送通知，请在didFinishLaunchingWithOptions方法中将以下代码添加到您的AppDelegate文件中：
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// 应用程序启动后用于自定义的替代点。
if UIDevice.currentDevice().systemVersion.compare(v, options: .NumericSearch) == NSOrderedAscending {
// Register for Push Notitications, if running iOS < 8
if application.respondsToSelector("registerUserNotificationSettings:") {
let types:UIUserNotificationType = (.Alert | .Badge | .Sound)
let settings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
} else {
// 在iOS 8之前注册推送通知
application.registerForRemoteNotificationTypes(.Alert | .Badge | .Sound)
}
} else {
var center = UNUserNotificationCenter.currentNotificationCenter()
center.delegate= self
center.requestAuthorizationWithOptions((UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge)) {(granted: Bool, error: NSError) -> Void in
if !error {
UIApplication.sharedApplication().registerForRemoteNotifications()
// 要求该应用程序完全执行关于推送通知的操作
print("推送注册成功。")
} else {
print("Push registration FAILED")
print("ERROR: \(error.localizedFailureReason!) - \(error.localizedDescription)")
print("SUGGESTIONS: \(error.localizedRecoveryOptions) - \(error.localizedRecoverySuggestion!)")
})
}
return true
}#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
if( SYSTEM_VERSION_LESS_THAN( @"10.0" ) )
{
if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
{
// iOS 8通知
[application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[application registerForRemoteNotifications];
}
else
{
// iOS < 8 Notifications
[application registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
}
}
else
{
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate= self;
[center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error)
{
if( !error )
{
[[UIApplication sharedApplication] registerForRemoteNotifications]; // 要求该应用程序完全执行关于推送通知的操作
NSLog( @"推送注册成功。" );
}
else
{
NSLog( @"Push registration FAILED" );
NSLog( @"ERROR: %@ - %@", error.localizedFailureReason,error.localizedDescription);
NSLog( @"SUGGESTIONS: %@ - %@", error.localizedRecoveryOptions,error.localizedRecoverySuggestion);
}
}];
}
//从推送通知中检查您的应用午餐
//---------------------------------------------------
//Handel Push通知
if (launchOptions != nil)
{
// 这里的应用程序将通过推送通知打开
//RemoteNotification
NSDictionary* dictionary1 = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
//LocalNotification
NSDictionary* dictionary2 = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (dictionary1 != nil)
{
//远程通知有效负载
NSLog(@"Launched from push notification: %@", dictionary1);
//在这里处理您的推送通知
}
if (dictionary2 != nil)
{
NSLog(@"Launched from dictionary2dictionary2dictionary2 notification: %@", dictionary2);
double delayInSeconds = 7;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
// [self addMessageFromRemoteNotification：dictionary2 updateUI：NO];
});
}
}
else
{}
//------------------------------------------------上面的代码将尝试与APNs服务器通信以获取设备令牌（前提是您在iOS设置配置文件中启用了APNs）。
一旦与APNs服务器建立可靠的连接，该服务器就会为您提供设备令牌。
在添加完上面的代码之后，将这些方法添加到AppDelegate类中：
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
print("DEVICE TOKEN = \(deviceToken)")
}
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
print(error)
}- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
NSString * deviceTokenString = [[[[deviceToken description]
stringByReplacingOccurrencesOfString: @"<" withString: @""]
stringByReplacingOccurrencesOfString: @">" withString: @""]
stringByReplacingOccurrencesOfString: @" " withString: @""];
NSLog(@"The generated device token string is : %@",deviceTokenString);
}
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
NSLog(@"Failed to get token, error: %@", error.description);
}根据注册成功或失败情况调用上述方法。
成功方案调用：
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
print("DEVICE TOKEN = \(deviceToken)")
}在Swift3中：
@objc(userNotificationCenter:willPresentNotification:withCompletionHandler:) @available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)
{
//在前台显示通知。
print("Userinfo2 \(notification.request.content.userInfo)")
}- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
if(application.applicationState == UIApplicationStateInactive) {
NSLog(@"Inactive - the user has tapped in the notification when app was closed or in background");
//做一些任务
[self handelPushNotification:userInfo];
}
else if (application.applicationState == UIApplicationStateBackground) {
NSLog(@"application Background - notification has arrived when app was in background");
[self handelPushNotification:userInfo];
}
else {
NSLog(@"application Active - notication has arrived while app was opened");
//显示应用内横幅
//做任务
}
}失败情况调用：
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
print(error)
}- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
注意
如果以上方法均未调用，则您的设备无法与APNs服务器建立可靠的连接，这可能是由于Internet访问问题所致。
