直接上程式碼

如果是ios10以下的版本嗎，需要在plist檔案裡面配置

NSURL *url = [NSURL URLWithString:@"App-Prefs:root=WIFI"];
            float version = [[[UIDevice currentDevice] systemVersion] floatValue];
            if (version >= 10.0){

                [[UIApplication sharedApplication] openURL:url options:@{} completionHandler:nil
 
];
            }else{

                if ([[UIApplication sharedApplication] canOpenURL:url]) {

                    [[UIApplication sharedApplication] openURL:url];
                }
            }
