有关用户接受推送通知(以及徽章等通知)的iOS8更改的两个问题。
1)我正在使用目前在iOS7和iOS8上都运行良好的方法
if ([[[UIDevice currentDevice] systemVersion] floatValue]>= 8.0) {
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:
(UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert)
categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
[[UIApplication sharedApplication] registerForRemoteNotifications];
} else {
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}
这完全起作用,因为推送和警报正在工作,我在didRegister委托方法中获得了令牌,但我从未被问过弹出窗口,因为它曾经是这种情况。即使我从手机中删除了应用程序? 为什么?操作系统是否会保留应用程序的内存隐私设置,即使它们已被删除?
2)我看到有人建议在以下代表中要求远程通知
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
NSLog(@"registered for notifications settings %@",notificationSettings);
//register to receive notifications
[application registerForRemoteNotifications];
}
为什么?
答案 0 :(得分:0)
从文档,- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
此方法回调将在调用 - [UIApplication registerUserNotificationSettings:]
时进行。用户授予应用程序的设置将作为第二个参数传入。这意味着,一旦我们获得用户权限(或者我们之前已经获得),那么此方法将调用,我们可以通过调用[application registerForRemoteNotifications]
来注册应用程序以进行远程通知。
