Can't click bar button on Tool bar? - ios

Question

In my iPad app, i add navigation bar and tool bar manually.
I also add scroll view and image view by coding.
My problem is i can see both navigation bar and tool bar.
I can click button on navigation bar.
But, i can't click bar button on tool bar.
How can i do it?
This is my code.
- (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];
}

Answer 1

I dont Know what is your exact problem, Because your displayed code is not related to UIToolBar.
But Following code i added two UIBarButton with flexSpace.
you can add UIBarButton as you want
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];
Following Method is call when tapped on bar Button
-(void)Cancel
{
// Write Code for Cancel Method
}
-(void)done
{
// Write Code for Done Method
}
This code might helpful in your own case.
Thanks :)

Thanks everybody. I can solve my problem.
I change my code.
UIScrollView *ScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 44, self.view.frame.size.width, self.view.frame.size.height)];
To this.
UIScrollView *ScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 44, self.view.frame.size.width, self.view.frame.size.height-88)];
