navigation bar image hiding custom navigation bar button

Question

I am able to give image to navigation bar and also changed image of navigation bar button item. For some reason navigation bar image, i guess, overlapped over navigation bar button image. Navigation bar button is functioning right when i click on navigation bar image at left but its not displaying over navigation bar image. here is the code ;

UIImage *imagebar = [UIImage imageNamed: @"schedule-strip.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage: imagebar];
imageView.frame = CGRectMake(0, 0, 190, 44);
imageView.contentMode = UIViewContentModeScaleAspectFill;
self.navigationItem.titleView = imageView;


UIImage* image = [UIImage imageNamed:@"back-icon.png"];
CGRect frame = CGRectMake(0, 0, image.size.width, image.size.height);
UIButton* someButton = [[UIButton alloc] initWithFrame:frame];
[someButton setBackgroundImage:image forState:UIControlStateNormal];
[someButton setShowsTouchWhenHighlighted:YES];
[someButton addTarget:self action:@selector(backToMore) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem* someBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:someButton];
[self.navigationItem setLeftBarButtonItem:someBarButtonItem];

[someBarButtonItem release];
[someButton release]; 

help me out.

Answer 1

use the code [imageView addsubView someButton];

I hope now u will see the button.Actually you are adding the left bar button item to default navigation bar and as u r creating somebutton it is not getting added on imageview which is overlapping your navigation bar.So by clicking on that area it is working but button is not visible.
