iOS用户是否打开APP通知开关跳转到系统的设置界面

1.检测用户是否打开推送通知

/**
 系统通知是否打开
 @return 是否打开
 */
//检测通知是否打开iOS8以后有所变化 所以需要适配iOS7 
+ (BOOL)openThePushNotification{
    if (IOS8) {//IOS8写的宏
        if ([[UIApplication sharedApplication] currentUserNotificationSettings].types  == UIUserNotificationTypeNone) {
//         未打开通知//这个是个自定义的alertView 当用户没有打开推送时  会弹出 可以替换成自己项目里面的弹框 
            openNotifiAlertView *alertView = [[openNotifiAlertView alloc] init];
            alertView.confirmClick = ^{
                if (IOS8) {//iOS8以后跳转到设置界面的代码也出现了变化 下面这段代码是直接跳转到APP的设置界面
                    //跳入当前App设置界面
                    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
                }else{
                    //适配iOS7 ,跳入系统设置界面
                    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:General&path=Reset"]];
                }            };
            [alertView show];
            
            return NO;
        }else{
            
            return YES;
        }
    }else{ // ios7
        if ([[UIApplication sharedApplication] enabledRemoteNotificationTypes]  == UIUserNotificationTypeNone) {
         
            openNotifiAlertView *alertView = [[openNotifiAlertView alloc] init];
            alertView.confirmClick = ^{
                if (IOS8) {
                    //跳入当前App设置界面
                    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
                }else{
                    //适配iOS7 ,跳入系统设置界面
                    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:General&path=Reset"]];
                }            };
            [alertView show];
            return NO;
        }else{
            
            return YES;
        }
    }

}
