ios 跳轉設定 ios7

    NSString * string = @"//prefs:root=工程名";

    if (IOS8) {

        string = [UIApplicationOpenSettingsURLString stringByAppendingString:string];

    } else {

        string = [@"app-settings:" stringByAppendingString:string];

    }

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:string]];

另外在info

在URL Types中添加一個新項，填寫工程名
