今天最近做了個(gè)遠(yuǎn)程推送功能古掏，未使用第三方開(kāi)發(fā)。發(fā)現(xiàn)一個(gè)問(wèn)題：在保證證書(shū)正確丧枪、網(wǎng)絡(luò)連接正常庞萍、首次進(jìn)入允許通知的情況下拧烦，獲取不到APNs的deviceTonken回調(diào)钝计。
既不調(diào)用application:didRegisterForRemoteNotificationsWithDeviceToken;方法
也不調(diào)用application:didFailToRegisterForRemoteNotificationsWithError:方法齐佳。
網(wǎng)上搜了不少資料债沮，結(jié)果大家給的解決方案幾乎都一致，把原因引向了iOS8.0+和iOS7系統(tǒng)問(wèn)題疫衩，并給出根據(jù)不同系統(tǒng)版本對(duì)remotNotifi進(jìn)行注冊(cè)的方法：
iOS8.0+ registerUserNotificationSettings：
iOS8.0- registerForRemoteNotificationTypes：
(還有人說(shuō)自己也不知道怎么了，后來(lái)就突然好了Ｌ嵴搿２芸！皆愉！)
找了很久很久很久...，都特么都是這個(gè)方法幕庐。
我想說(shuō)：這特么誰(shuí)不知道。
被逼無(wú)奈瑟由，我只能一步一步的從申請(qǐng)證書(shū)到代碼編寫(xiě)一步一步的檢查冤寿，一步一步的看...還是沒(méi)找到原因。我累個(gè)艸了督怜。
沒(méi)辦法了，只能從appdelegate代理方法入手号杠，找原因和解決方法。
原因是沒(méi)找到屉凯，但是解決方法卻找到了，直接貼代碼：
// This callback will be made upon calling -[UIApplication registerUserNotificationSettings:]. The settings the user has granted to the application will be passed in as the second argument.
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings NS_AVAILABLE_IOS(8_0) __TVOS_PROHIBITED;
iOS8.0以后可以用這個(gè)作為second argument悠砚。然后：
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings{
[application registerForRemoteNotifications];
}
果斷解決了偷仿，什么deviceToken問(wèn)題都沒(méi)有了。
一個(gè)推送做的我心累酝静，雖然我不知道什么原因?qū)е碌墨@取不到deviceToken，但是問(wèn)題總算解決了宗苍。
代碼：
//remote 授權(quán)
- (void)registRemoteNotification{
#ifdef __IPHONE_8_0
if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
} else {
UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];
}
#else
UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];
#endif
}
