REPhotoCollectionController

###REPhotoCollectionController is a simple photo thumbnail viewer for the iOS that groups photos by date.

Requirements

Xcode 4.3 or higher
Apple LLVM compiler
iOS 4 or higher
ARC

If you are not using ARC in your project, add -fobjc-arc as a compiler flag for all the files in this project.

Demo

Build and run the REPhotoCollectionController project in Xcode to see REPhotoCollectionController in action.

Installation

Clone the git repository: git clone https://github.com/romaonthego/REPhotoCollectionController.git.
Example project requires 2 submodules: EGOCache and EGOImageLoading, so the next step is to update submodules: git submodule init && git submodule update && git submodule status

Using REPhotoCollectionController

To use REPhotoCollectionController copy the source code into your project then add photo objects to a data source class for your photos. Here is how:

Add a new class to your project called "Photo" or something similar. This class MUST implement the protocol REPhotoObjectProtocol:

@protocol REPhotoObjectProtocol <NSObject>

@property (nonatomic, strong) NSDate *date;

@optional
@property (nonatomic, strong) NSURL *thumbnailURL;
@property (nonatomic, strong) UIImage *thumbnail;

- (id)initWithThumbnailURL:(NSURL *)thumbnailURL date:(NSDate *)date;

@end

Implement the methods required by the protocol REPhotoObjectProtocol and implement the optional methods if needed.
Add a new class to your project called "ThumbnailView", its parent class MUST be REPhotoThumbnailView. This class will be used a photo thumbnail representation view, you can customize it however you want, e.g. use different libraries for remote image fetching, etc. Sample goes below:

#import "ThumbnailView.h"

@implementation ThumbnailView

- (void)setPhoto:(NSObject <REPhotoObjectProtocol> *)photo
{
    if (photo.thumbnailURL) {
        imageButton.imageURL = photo.thumbnailURL;
    } else {
        [imageButton setImage:photo.thumbnail forState:UIControlStateNormal];
    }
}

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        imageButton = [[EGOImageButton alloc] initWithPlaceholderImage:[UIImage imageNamed:@""]];
        imageButton.frame = CGRectMake(1, 1, self.frame.size.width - 2, self.frame.size.height - 2);
        [self addSubview:imageButton];
    }
    return self;
}

@end

Getting things together:

NSMutableArray *datasource = [[NSMutableArray alloc] init];
Photo *photo = [[Photo alloc] init];
photo.thumbnail = [UIImage imageName:@"testimage"]; // Set photo here
photo.date = [NSDate date]; // Set date here
[datasource addObject:photo];

REPhotoCollectionController *photoCollectionController = [[REPhotoCollectionController alloc] initWithDatasource:datasource];
photoCollectionController.title = @"Photos";

// Use custom thumbnail view class
photoCollectionController.thumbnailViewClass = [ThumbnailView class];

[self.navigationController pushViewController:photoCollectionController animated:YES];

Use method reloadData to refresh datasource when you add more photo objects.
