判断用户有没有开启通知（没有跳转到通知界面）

iOS10系统这个只能跳转到设置界面，不能具体到哪一个页面

    UIUserNotificationSettings *setting = [[UIApplication sharedApplication] currentUserNotificationSettings];
    if (UIUserNotificationTypeNone == setting.types) {
        NSLog(@"推送关闭");
         [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
    }else{
        NSLog(@"推送打开");
    }

所有需要使用系统的私有API来处理问题了
需要添加类库文件：MobileCoreServices.framework

~~还需要在info.plist中添加这两个key对应的值如图，区分大小写（测试发现不添加也没用问题）~~

在需要跳转的地方添加如下代码

NSURL*right_url=[NSURL URLWithString:@"Prefs:root=Bluetooth"];
Class LSApplicationWorkspace = NSClassFromString(@"LSApplicationWorkspace");

[[LSApplicationWorkspace performSelector:@selector(defaultWorkspace)] performSelector:@selector(openSensitiveURL:withOptions:) withObject:right_url withObject:nil];

更换其中的字符串，实现跳转到不同的页面(注意：开通的p改为大写！！！！)
