在iOS开发中,我们经常会碰到使用位置、使用WIFI、使用的蓝牙等需求。当我们的app不允许使用位置的时候,最好的用户体验就是跳到位置设置界面,进行设置。
跳转到自己的项目的设置界面中
在需要调转的按钮动作中添加如下的代码,就会跳转到设置中自己的app的设置界面,这里会有通知和位置权限的设置
NSURL * url = [NSURLURLWithString:UIApplicationOpenSettingsURLString];
if([[UIApplicationsharedApplication] canOpenURL:url]) {
NSURL*url =[NSURLURLWithString:UIApplicationOpenSettingsURLString];
[[UIApplicationsharedApplication] openURL:url];
}
跳转到系统设置的其他界面
1、参数配置

2、在项目中的info中添加 URL types
如果想要在iOS6.0以后的版本进行跳转的话,必须附加以下的设置,添加 URL Schemes 为 prefs的url

3、跳转界面
定位服务
//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];
}
faceTime
//FaceTime设置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=FACETIME"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
[[UIApplication sharedApplication] openURL:url];
}
蓝牙
//蓝牙设置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=Bluetooth"];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
