如何跳到系统设置里的各种设置界面

WiFi界面

NSURL *url = [NSURL URLWithString:@"prefs:root=WIFI"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
    [[UIApplication sharedApplication] openURL:url];
}

定位服务

定位服务有很多APP都有，如果用户关闭了定位，那么，我们在APP里面可以提示用户打开定位服务。点击到设置界面设置，直接跳到定位服务设置界面。代码如下：

//定位服务设置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
    [[UIApplication sharedApplication] openURL:url];
}

这样就可以跳到系统设置的定位服务界面啦！我们继续看几个列子。

FaceTim

//FaceTime设置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=FACETIME"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
    [[UIApplication sharedApplication] openURL:url];
}

音乐

//音乐设置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=MUSIC"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
    [[UIApplication sharedApplication] openURL:url];
}

墙纸设置界面

//墙纸设置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=Wallpaper"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
    [[UIApplication sharedApplication] openURL:url];
}

蓝牙设置界面

//蓝牙设置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=Bluetooth"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
   [[UIApplication sharedApplication] openURL:url];
}

iCloud设置界面

//iCloud设置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=CASTLE"];
if ([[UIApplication sharedApplication] canOpenURL:url]
{
   [[UIApplication sharedApplication] openURL:url];
}
