README
iOS Ken Burns effect
====================
**The goal of this project is to create a `UIView` that can generate a Ken Burns transition when given an array of `UIImage` objects.**
![image]()
To use it, you simply need an instance of `JBKenBurnsView` and call this method to start the action:
``` objc
[self.kenView animateWithImages:myImages
transitionDuration:6
initialDelay:0
loop:YES
isLandscape:YES];
```
## Installation
I recommend use [CocoaPods](http://cocoapods.org) to install JBKenBurnsView. Simply add the following line to your `Podfile`:
#### Podfile
```ruby
pod 'JBKenBurnsView'
```
But you can also just drop `JBKenBurnsView.m` and `JBKenBurnsView.h` in your project.
## Documentation
The project is documented using AppleDocs syntax. But this is a summary:
#### Start the slideshow
You can start an animation using an `NSArray` of `UIImage` or `NSString` with the paths to the images calling:
``` objc
- (void)animateWithImages:(NSArray *)images
transitionDuration:(float)time
initialDelay:(float)delay
loop:(BOOL)isLoop
isLandscape:(BOOL)isLandscape;
```
or
``` objc
- (void)animateWithImagePaths:(NSArray *)imagePaths
transitionDuration:(float)time
initialDelay:(float)delay
loop:(BOOL)isLoop
isLandscape:(BOOL)isLandscape;
```
1. `images:` NSArray of UIImages.
2. `time:` Time in seconds for the transition between images.
3. `delay:` Time in seconds until the transition should start.
4. `isLoop:` YES if the animation should start again when ended.
5. `isLandscape:` If YES optimized to show in Landscape mode.
#### Stop the animation
When the transition has started you can stop the animation calling:
`- (void)stopAnimation;`
#### Add new images to the animation
Or add new images to the array of images in the slide show with:
`- (void)addImage:(UIImage *)image;`
#### KenBurnsViewDelegate
There is a protocol that notifies to the delegate when an image changes or the slideshow ended.
``` objc
@protocol KenBurnsViewDelegate
@optional
- (void)kenBurns:(JBKenBurnsView *)kenBurns didShowImage:(UIImage *)image atIndex:(NSUInteger)index;
- (void)kenBurns:(JBKenBurnsView *)kenBurns didFinishAllImages:(NSArray *)images;
@end
```
## TODO
* Need to allow device rotation.
* Improvements on image transition effects.
## Demo
Build and run the `KenBurnsDemo` project in Xcode to see `JBKenBurnsView` in action.
## Swift version
[@gatada](https://github.com/gatada) wrote a Swift version of `JBKenBurnsView` that you can find [here](https://github.com/Gatada/JBKenBurnsView).
