3.代码说明：

①打开应用对应的系统设置页

NSURL * url = [NSURLURLWithString:UIApplicationOpenSettingsURLString];
if([[UIApplication sharedApplication] canOpenURL:url]) {
        NSURL *url =[NSURLURLWithString:UIApplicationOpenSettingsURLString];
        [[UIApplication sharedApplication] openURL:url];
    }

②跳转到系统设置的其他界面

[[UIApplication sharedApplication] openURL:[NSURLURLWithString:@"prefs:root=WIFI"]];

在项目中的info中添加 URL types，添加 URL Schemes 为 prefs
