看了好几个帖子在讨论相应的问题，我也是遇到了此问题查了很久没找出didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken 不执行的原因。
其实很多文章没写清楚根本原因，除了或许代码原因、证书原因、还有其他原因的
首先我们来看看注册通知代码应该如何写
1、ios10应该这样写，首先导入框架 <UserNotifications/UserNotifications.h>
if([[[UIDevicecurrentDevice]systemVersion]floatValue]>=10.0) {
UNUserNotificationCenter*center = [UNUserNotificationCentercurrentNotificationCenter];
UNAuthorizationOptionsoptions =UNAuthorizationOptionBadge|UNAuthorizationOptionSound|UNAuthorizationOptionAlert;
[centerrequestAuthorizationWithOptions:optionscompletionHandler:^(BOOLgranted,NSError*_Nullableerror) {
if(granted) {
[[UIApplicationsharedApplication]registerForRemoteNotifications];
NSLog(@"通知授权");
}
else{
}
}];
}
2、ios 8 到 ios 10之间这样写
if([application
respondsToSelector:@selector(registerUserNotificationSettings:)]) {
//注册推送,用于iOS8以及iOS8之后的系统
UIUserNotificationSettings*settings = [UIUserNotificationSettings
settingsForTypes:(UIUserNotificationTypeBadge|
UIUserNotificationTypeSound|
UIUserNotificationTypeAlert)
categories:nil];
[applicationregisterUserNotificationSettings:settings];
//[application registerForRemoteNotifications];
}
另外一个重要的步骤不要忘记了，在工程Target中的Push Notifications 的开关要开启！否则死活获取不到token。这点很多网友都没提及到。
希望对大家有帮助
