iOS 调用用户设置界面

ios --- 调用系统"设置"里的功能(转)


安装后第一次运行软件时，系统会弹出提示用户是否允许软件获取当前位置，如果用户不允许的话，之后运行时系统不会在弹出提示设置，这点很不方便，有个解决办法是给用户一个选项，调出iphone中“设置”定位服务选项，由用户手动设置，调用系统“设置”中定位服务相关代码如下：


-(IBAction)btnSetting:(id)sender{ 
    NSURL*url=[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]; 
    [[UIApplication sharedApplication] openURL:url]; 
}
