apple-push-notifications - if([应用程序responsToSelector:@selector(registerUserNotificationSettings :)])-引发构建错误

Xcode：6.0版（6A313）

推送通知部分从解析中直接获取

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

引发以下错误：

 Unknown receiver 'application'; did you mean 'UIApplication'?

最佳答案

试试此代码，可能对您有用。

 -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
 if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
{
    // iOS 8 Notifications
    [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

    [application registerForRemoteNotifications];
}
else
{
    // iOS < 8 Notifications
    [application registerForRemoteNotificationTypes:
     (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
}
return YES;
}
