DRDynamicSlideShow

Create beautiful, animated, paging UIScrollViews. Easily animate views as the UIScrollView gets paged. This is perfect for welcome screens and introduction views in iOS apps.

Features

• 1 line of code per animation.
• Any type of value can be animated.
• Block-driven.

Installation

There are two ways to install DRDynamicSlideShow. The first (and preferred / recommended) method is through CocoaPods. If you prefer to do it the classic way, see instructions for manual install below.

CocoaPods Install

You can install DRDynamicSlideShow through CocoaPods by adding the following to your Podfile:

pod 'DRDynamicSlideShow'

Manual Install

You can add DRDynamicSlideShow to your project by copying DRDynamicSlideShow.h and DRDynamicSlideShow.m. Ensure that they are copied into the project. Note, installing with this method will not keep DRDynamicSlideShow updated (you'll need to check GitHub).

Usage

Using DRDynamicSlideShow is easy. There are two ways to use it - either set it up programatically or with an interface. The demo project demonstrates setup with a Storyboard.

1. Add a DRDynamicSlideShow instance to your view.

2. Use the following method to add subviews to it on the page you want (you can simply use addSubview: as well):

    [self.slideShow addSubview:coolSubview onPage:0];
   

3. Just need add whatever animation you want it to perform for those subviews when the specified page is being swiped.

    [self.slideShow addAnimation:[DRDynamicSlideShowAnimation animationForSubview:coolSubview page:0 keyPath:@"alpha" toValue:@0 delay:0]];
   

   OR

    [self.slideShow addAnimation:[DRDynamicSlideShowAnimation animationForSubview:coolSubview page:0 keyPath:@"alpha" fromValue:@0 toValue:@1 delay:0]];
   

Notice there are two ways for instantiating DRDynamicSlideShowAnimation. If you want the subview to animate from its current value, just use animationForSubview:page:keyPath:toValue:delay:. Otherwise, use animationForSubview:page:keyPath:fromValue:toValue:delay:.

As you can see, all we need for adding each animation is just 1 line of code! Pretty amazing, isn't it? :)
