解析不起作用的iOS 7

Question

My app crash when i run on iOS7 device !

So i tried :

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_8_0
    if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
        UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
    } else {
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
    }
#else
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert   )];
#endif

iOS 8 Device is correct but iOS 7 Device the push notification no working :(

any ideas?

Note:

I have the code of another app i used:

[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge|
 UIRemoteNotificationTypeAlert|
 UIRemoteNotificationTypeSound];

but now is not working

I'm using this code for a current app of iOS 7 and it is working fine. In ApplicationDidFinishLaunchingWithOptions write the same as you have written before.

[application registerForRemoteNotificationTypes:
     UIRemoteNotificationTypeBadge |
     UIRemoteNotificationTypeAlert |
     UIRemoteNotificationTypeSound];

Don't forget to add this to your AppDelegate

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
    [application registerForRemoteNotifications];
}

It is hard to know what you're missing in the code without the log message however my guess is that you didn't register user for notification settings. Cheers!
