最近计划在app中实现跳转到私隐设置界面的功能，刚好看到网友的分享，于是记录一下

  NSString* phoneVersion = [[UIDevice currentDevice] systemVersion];
    if (phoneVersion.floatValue < 10.0) {
        //iOS10 以前使用
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"Tel://123456"]];
    }
    else {
        //iOS10 以后使用
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"Tel://123456"]
                                           options:@{}
                                 completionHandler:nil];
    }

//拨打电话
[NSURL URLWithString:@"tel://123456"] 
//发送短信
[NSURL URLWithString:@"sms://123456"]
//发邮件
[NSURL URLWithString:@"mailto://123456@163.com"]
//前往App Store
[NSURL URLWithString:@"itms-apps://"]
//使用Safari访问网址
[NSURL URLWithString:@"http://www.baidu.com"]
//前往iBook
[NSURL URLWithString:@"itms-books://"]
//发起Facetime
[NSURL URLWithString:@"facetime://"]
//8、调用 地图Map
[NSURL URLWithString:@"maps://"]
//9、调用 Music
[NSURL URLWithString:@"music://"]
//10、跳转到系统设置相关界面
    // iOS10 以前
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION"] options:@{} completionHandler:nil];
    // iOS10 以后
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"App-Prefs:root=LOCATION"] options:@{} completionHandler:nil];
