在全局UINavigationController中添加如下代码 

- (void)viewDidLoad {

    [self addHeaderTouch];

    [super viewDidLoad];

    // Do any additional setup after loading the view.

}

- (void)addHeaderTouch

{

    self.navigationBar.topItem.titleView.backgroundColor = [UIColor redColor];

    NSLog(@"%@",self.navigationController.navigationBar);

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(touchTap:)];

    tap.numberOfTapsRequired = 6;

    [self.navigationBar addGestureRecognizer:tap];

}

- (IBAction)touchTap:(UITapGestureRecognizer *)tap

{

    NSLog(@"touchTap");

    [self showActionView];

}

- (void)showActionView

{

    NSLog(@"showActionView");

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"设置服务器IP" message:@"\n【确定】切换到指定IP\n【线上】切换到线上服务器" delegate:self cancelButtonTitle:@"线上" otherButtonTitles:@"确定", nil];

    [alert setAlertViewStyle:UIAlertViewStylePlainTextInput];

    self.inputText = [alert textFieldAtIndex:0];

    self.inputText.text = @"192.168.";

    [alert show];

}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

{

    if (buttonIndex == [alertView cancelButtonIndex]) {

        NSLog(@"线上");

        [APPConfig setServerIp:@"线上服务器地址"];

    }else {

        [APPConfig setServerIp:self.inputText.text];

        NSLog(@"确定");

    }

}
