我在视图控制器按钮操作中有以下代码：
@H_502_2@- (IBAction)requestPermissions:(id)sender
{
DDLogInfo(@"Start permission requesting.");
if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerForRemoteNotifications)]){
[[UIApplication sharedApplication] registerForRemoteNotifications];
} else {
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(didBecomeActive:)
name:UIApplicationDidBecomeActiveNotification
object:nil];
[[UIApplication sharedApplication]
registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeSound];
}
}
@H_502_2@-(void)didBecomeActive:(NSNotification *)notification
{
if([[UIApplication sharedApplication] enabledRemoteNotificationTypes] == UIRemoteNotificationTypeNone){
// if user decline
}
} else {
// if user accept
}
所以我的问题是：如果用户拒绝接收推送通知并稍后决定启用它们(设置 – >通知中心 – >我的应用程序),则会出现意外：启用“警报”,“徽章”和“声音”在“设置”中,但应用程序返回UIRemoteNotificationTypeNone.
有什么想法有什么不对？
注意：我知道这些方法已被弃用,所以请不要告诉我使用registerForRemoteNotifications：和UIUserNotificationSettings,它已经完成了.
