引导用户去打开 在 URL Types 添加 一个叫 prefs 的 URL Schemes
- iOS 系统功能的 URL 汇总列表：
蜂窝网络：prefs:root=MOBILE_DATA_SETTINGS_ID
VPN — prefs:root=General&path=Network/VPN
Wi-Fi：prefs:root=WIFI
定位服务：prefs:root=LOCATION_SERVICES
个人热点：prefs:root=INTERNET_TETHERING
关于本机：prefs:root=General&path=About

备注: 有的可能跳不过去 请把 path后面的 大写
- iOS8 以上貌似可以跳到对应的应用，然后去设置
NSString *prefs = [NSString stringWithFormat:@"prefs:root=%@",[[NSBundle mainBundle] bundleIdentifier]];
NSURL *url = [NSURL URLWithString:prefs];
if ([UIDevice currentDevice].systemVersion.doubleValue > 8.0f) {
url= [NSURL URLWithString:UIApplicationOpenSettingsURLString];
}
if([[UIApplication sharedApplication]canOpenURL:url]){
[[UIApplication sharedApplication]openURL:url];
}
配置下 url type
