Question

在我的iPad应用程序中，我手动添加导航栏和工具栏我还通过编码添加滚动视图和图像视图。

我的问题是我可以看到导航栏和工具栏我可以点击导航栏上的按钮但是，我无法单击工具栏上的条形按钮。

我该怎么做？

这是我的代码。

- (void)viewDidLoad
{

[super loadView];
self.view.backgroundColor = [UIColor grayColor];

UIScrollView *ScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 44, self.view.frame.size.width, self.view.frame.size.height)];
ScrollView.pagingEnabled = YES;

NSInteger numberOfViews = 4;
for (int i = 0; i < numberOfViews; i++) {
    CGFloat xOrigin = i * self.view.frame.size.width;

    // Create a UIImage to hold Info.png
    UIImage *image1 = [UIImage imageNamed:@"Image-001.jpg"];
    UIImage *image2 = [UIImage imageNamed:@"Image-002.jpg"];
    UIImage *image3 = [UIImage imageNamed:@"Image-003.jpg"];
    UIImage *image4 = [UIImage imageNamed:@"Image-004.jpg"];

    NSArray *images = [[NSArray alloc] initWithObjects:image1,image2,image3,image4,nil];

    UIImageView *ImageView = [[UIImageView alloc] initWithFrame:CGRectMake(xOrigin, 0, self.view.frame.size.width, self.view.frame.size.height-88)];
    [ImageView setImage:[images objectAtIndex:i]];

    [ScrollView addSubview:ImageView];
}

ScrollView.contentSize = CGSizeMake(self.view.frame.size.width * numberOfViews, self.view.frame.size.height);
[self.view addSubview:ScrollView];
}

我不知道您的确切问题是什么，因为您显示的代码与UIToolBar无关。

但是以下代码我添加了两个UIBarButton flexSpace 您可以根据需要添加UIBarButton

UIToolbar *Toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
    Toolbar = UIBarStyleBlackTranslucent;
    [Toolbar sizeToFit];

     NSMutableArray *barItems = [[NSMutableArray alloc] init];
    UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
    [barItems addObject:flexSpace];
    [flexSpace release];

    UIBarButtonItem *btnCancel = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(Cancel)];
    [barItems addObject:btnCancel];

    UIBarButtonItem *btnDone = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleBordered target:self action:@selector(done)];
    [barItems addObject:btnDone];

    [Toolbar setItems:barItems animated:YES];

点击按钮

时，会调用以下方法

-(void)Cancel
{
  // Write Code for Cancel Method
}

-(void)done
{
  // Write Code for Done Method
}

此代码可能对您自己的情况有所帮助。

谢谢大家。我可以解决我的问题我改变了我的代码。

UIScrollView *ScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 44, self.view.frame.size.width, self.view.frame.size.height)];

对此。

UIScrollView *ScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 44, self.view.frame.size.width, self.view.frame.size.height-88)];

无法单击工具栏上的栏按钮？
