registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later

2014-11-01

升级了xcode到6后，xcode5（ios7）中的工程在build后，调试output提示：registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later

iOS 8 has changed notification registration in a non-backwards compatible way. While you need to support iOS 7 and 8 (and while apps built with the 8 SDK aren’t accepted), you can check for the selectors you need and conditionally call them correctly for the running version.

Here’s a category on UIApplication that will hide this logic behind a clean interface for you that will work in both Xcode 5 and Xcode 6.

注册方式:

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings
settingsForTypes:(UIUserNotificationTypeSound |
UIUserNotificationTypeAlert |
UIUserNotificationTypeBadge)
categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
else {
//这里还是原来的代码
[[UIApplication sharedApplication]registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert|
UIRemoteNotificationTypeBadge|
UIRemoteNotificationTypeSound];
}

原本在IOS7当中判断PUSH是否打开的方法是：

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
return (types & UIRemoteNotificationTypeAlert);

如果将这段代码使用在 IOS当中，不会出现crash的现象，但是基本没什么作用。
在IOS8中，使用如下的新代码来取代以上的代码

UIRemoteNotificationType types;

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)

{

types = [[UIApplication sharedApplication] currentUserNotificationSettings].types;

}

else

{

types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];

}

return (types & UIRemoteNotificationTypeAlert);
