Question

我的UITabbar的下半部分没有响应。我找到了更多有问题的人，但没有解决方案。

我认为问题可能是由于我没有使用tabbar作为全屏应用程序，而只是屏幕的一部分（iPhone上的320 * 380）。但是，我使用自定义UITabbarController。这是在我的UITabbarController子类的构造函数之后：

    -(void)addCustomElements
{
    UIImageView *tabBarBackground = [[UIImageView alloc] initWithFrame:CGRectMake(0, 306, 320, 74)];
    [tabBarBackground setImage:[UIImage imageNamed:@"Tab Bottom.png"]];
    [self.view addSubview:tabBarBackground];

    UIImage *buttonImage = [UIImage imageNamed:@"Places Tab.png"];
    UIImage *selectedImage = [UIImage imageNamed:@"Places Tab Selected.png"];

    btn1 = [UIButton buttonWithType:UIButtonTypeCustom];
    btn1.frame = CGRectMake(0, self.view.frame.size.height-42, 160, 44);
    [btn1 setImage:buttonImage forState:UIControlStateNormal];
    [btn1 setImage:selectedImage forState:UIControlStateSelected];
    [btn1 setTag:0];
    [btn1 setSelected:YES];

    buttonImage = [UIImage imageNamed:@"Map Tab.png"];
    selectedImage = [UIImage imageNamed:@"Map Tab Selected.png"];
    btn2 = [UIButton buttonWithType:UIButtonTypeCustom];
    btn2.frame = CGRectMake(160, self.view.frame.size.height-42, 160, 44);
    [btn2 setImage:buttonImage forState:UIControlStateNormal];
    [btn2 setImage:selectedImage forState:UIControlStateSelected];
    [btn2 setTag:1];

    [self.view addSubview:btn1];
    [self.view addSubview:btn2];

    [btn1 addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
    [btn2 addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];      
  }

我这样创造它：

tabBarController = [[CustomTabbar alloc]init];
        tabBarController.view.frame=CGRectMake(0, 0, 320, 380);
        [tabBarController viewDidAppear:NO];
        mapsView = [[MapView alloc]init];
        placesView = [[FavoritesList alloc]init];
            //Suggestions from another forum (didn't work):
        //[mapsView setWantsFullScreenLayout:YES];
        //[placesView setWantsFullScreenLayout:YES];

        mapsView.title=@"Maps";
        placesView.title=@"Places";

        placesView.mapView=mapsView;
        mapsView.favorites=placesView;

        NSArray *controllers = [NSArray arrayWithObjects:placesView, mapsView, nil];
        [tabBarController setViewControllers:controllers];

        [self addSubview:tabBarController.view];

有人知道修复此问题吗？
