I make use of ICViewPager
to create tabs of contents. However, the layout looks weird as there are strange spaces at the top & bottom of ICViewPager
's content view.
As you can see below, I have a UINavigationBar
at the top of the screen, which is generated by the embedding UINavigationController
. Then, the UINavigationController
is made to be one of the tabs in a UITabbar Controller
. Here is the structure:
UITabbarController --> UINavigationController --> TabVC (which contains ICViewPager) --> Content views: Content1VC, Content2VC, Content3VC
Here are the codes in TabVC
(which configs to have <ViewPagerDataSource, ViewPagerDelegate>
):
// in viewDidLoad
self.dataSource = self;
self.delegate = self;
self.edgesForExtendedLayout = UIRectEdgeNone;
and for the delegate methods:
#pragma mark - ViewPagerDataSource
- (NSUInteger)numberOfTabsForViewPager:(ViewPagerController *)viewPager {
return tabsContents.count;
}
- (UIView *)viewPager:(ViewPagerController *)viewPager viewForTabAtIndex:(NSUInteger)index {
UILabel *label = [UILabel new];
label.text = [tabsContents objectAtIndex:index];
label.textColor = [UIColor colorWithRed:136/255.0 green:136/255.0 blue:136/255.0 alpha:1.0f];
[label sizeToFit];
return label;
}
- (UIViewController *)viewPager:(ViewPagerController *)viewPager contentViewControllerForTabAtIndex:(NSUInteger)index {
UIViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:[tabsVC objectAtIndex:index]];
return vc;
}
The functions look okay, but the layout does not span through the whole spaces as it expects to do so. The red spaces (I made the TabVC view's background color to red to illustrate the issue) are not expected to appear. How do I make the ICViewPager
occupy the red spaces?
Note: This appears only after the view is popped back from a pushed view controller, or changing tabs in UITabbarController
