问题
I've just started with ios development. I've been playing with little code here and there. I thought I should make a small goal to achieve so that I gain some confidence and feel familiar with iOS environment.. I saw this app (see below) and wanted to make a clone (not to sell it). When you see the app and when you click "Tips" tab there you can see in navigation bar there are 2 buttons one is right arrow and one is left. When you click there it shows another Weight Loss Tip. I don't get it, how he is able to only change the text?
I'm not asking code but just an idea. Thanks!
Any help?

I think you should have a look at UIPageViewController. Check out the links below to have an idea on how to implement it.

For change views with animation you can use those methods:
[super didReceiveMemoryWarning];
[UIView transitionFromView:(UIView *) toView:(UIView *) duration:(NSTimeInterval) options:(UIViewAnimationOptions) completion:^(BOOL finished) {
}];
[UIView transitionWithView:(UIView *) duration:(NSTimeInterval) options:(UIViewAnimationOptions) animations:^{
} completion:^(BOOL finished) {
}];
