ios devicetoken 怎么获取csdn

Answer 1

最近升级设备，测试时发现无法获得设备token,查资料发现，原来ios的apns注册与以往不同了。
首先在
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions中将之前注册推送代码更改如下：

//APNS注册

//APNS 注册
if (iOS8) {
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge
|UIRemoteNotificationTypeSound
|UIRemoteNotificationTypeAlert) categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}else
{
UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];
}

注：
#define iOS8 [[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0 ? 1 : 0

然后添加两个ios8的新方法

#pragma mark APPLE APNS

#ifdef __IPHONE_8_0
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
//register to receive notifications
[application registerForRemoteNotifications];
}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler
{
//handle the actions
if ([identifier isEqualToString:@"declineAction"]){
}
else if ([identifier isEqualToString:@"answerAction"]){
}
}
#endif

下面就可以正常在“
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
”中获取设备token 了

如果获取失败，可以在“
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
”中打印错误信息
