Question

I’m new to Xcode development and have a (hopefully simple) question:

I want to write an iPad App which shows a document in an UIPageView and in addition shows a bar at the bottom to navigate in the document (i.e. with buttons on it for each chapter).
This bar should automatically hide (except a small grip) while switching pages and show up when pressing (or dragging) the grip.
The bar should overlap the PageView (PageView not resized).

I already finished the PageView (based on the template in XCode) but don’t know the best way to implement the bottom-bar.

Any suggestions?
Examples welcome.

Answer 1

to show

[self doSingleViewHideAnimation:myToolBar:kCATransitionFromBottom];


-(void)doSingleViewHideAnimation:(UIView*)incomingView:(NSString*)animType
{   
CATransition *animation = [CATransition animation];
[animation setType:kCATransitionPush];
[animation setSubtype:animType];

[animation setDuration:0.5];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[[incomingView layer] addAnimation:animation forKey:kCATransition];
incomingView.hidden = YES;
}

To hide

[self doSingleViewShowAnimation:myToolBar:kCATransitionFromTop];



-(void)doSingleViewShowAnimation:(UIView*)incomingView:(NSString*)animType
{   
CATransition *animation = [CATransition animation];
[animation setType:kCATransitionPush];
[animation setSubtype:animType];

[animation setDuration:0.5];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[[incomingView layer] addAnimation:animation forKey:kCATransition];
incomingView.hidden = NO;
}
