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！！！！)
