?系統(tǒng)設(shè)置
前言
一個(gè)APP應(yīng)用能不能跳到系統(tǒng)的設(shè)置界面呢？比如：WiFi、定位服務(wù)、FaceTime、音樂(lè)?
其實(shí)這些都是可以做到的，一起來(lái)看看如何實(shí)現(xiàn)的！
Wi-Fi
//FaceTime設(shè)置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=WIFI"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
[[UIApplication sharedApplication] openURL:url];
}
定位服務(wù)
定位服務(wù)有很多APP都有，如果用戶(hù)關(guān)閉了定位，那么，我們?cè)贏PP里面可以提示用戶(hù)打開(kāi)定位服務(wù)。點(diǎn)擊到設(shè)置界面設(shè)置，直接跳到定位服務(wù)設(shè)置界面。代碼如下：
//定位服務(wù)設(shè)置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
[[UIApplication sharedApplication] openURL:url];
}
Face Time
//FaceTime設(shè)置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=FACETIME"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
[[UIApplication sharedApplication] openURL:url];
}
藍(lán)牙設(shè)置界面
//藍(lán)牙設(shè)置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=Bluetooth"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
[[UIApplication sharedApplication] openURL:url];
}
iCloud設(shè)置界面
//iCloud設(shè)置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=CASTLE"];
if ([[UIApplication sharedApplication] canOpenURL:url]
{
[[UIApplication sharedApplication] openURL:url];
}
參數(shù)配置
看到這幾個(gè)例子，大家有沒(méi)有發(fā)現(xiàn)，想跳到哪個(gè)設(shè)置界面只需要prefs:root=后面的值即可！是的，就是這樣的。
