iOS 判断是否开启定位

+ (BOOL)isLocationServiceOpen {
   if ([ CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied) {
       return NO; 
    } else 
       return YES;
}

iOS 判断是否允许消息通知

- ios10以及之后版本
+ (void)isMessageNotificationServiceOpenBlock:(void (^)(BOOL))block{
    
    if ([[UIDevice currentDevice].systemVersion doubleValue] >= 10.0) {
        
        [[UNUserNotificationCenter currentNotificationCenter] getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
            
            NSLog(@"setting = %@",settings);
            
            if(settings.authorizationStatus == UNAuthorizationStatusAuthorized){
                
                if (block) {

                }
            }

            block(UIRemoteNotificationTypeNone != [[UIApplication sharedApplication] enabledRemoteNotificationTypes]);
        }
    }
}

- ios10之前版本
+ (BOOL)isMessageNotificationServiceOpen { 
       if (SYSTEM_VERSION_GREATER_THAN(@"8.0")) {
              BOOL pushEnabled;
// 设置里的通知总开关是否打开
              BOOL settingEnabled = [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];
// 设置里的通知各子项是否都打开

 return pushEnabled; 
      } else { 
             return UIRemoteNotificationTypeNone != [[UIApplication sharedApplication] enabledRemoteNotificationTypes]; 
       }
}

iOS 跳转系统设置打开定位页面

if (SYSTEM_VERSION_GREATER_THAN(@"8.0")) { 
        NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString]; 
        if ([[UIApplication sharedApplication] canOpenURL:url]) {
                    [[UIApplication sharedApplication] openURL:url]; 
         } 
 } else {
         [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]]; 
 }

iOS 跳转系统设置打开消息页面

if (SYSTEM_VERSION_GREATER_THAN(@"8.0")) { 
     NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString]; 
     if ([[UIApplication sharedApplication] canOpenURL:url]) {
           [[UIApplication sharedApplication] openURL:url]; 
      }
 } else { 
      [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=NOTIFICATIONS_ID"]];
