iOS8.0之后没有注册通知的提醒解决办法

在iOS8.0之后如果没注册本地通知就会报出的提醒，如下图：

解决的办法是：在

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

这个方法中注册通知：

if ([[UIDevice currentDevice].systemVersion doubleValue]>=8.0) {

        UIUserNotificationSettings* settings=[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil];

        [application registerUserNotificationSettings:settings];

    }

    return YES;
