The usage and look-and-feel are just similar to UIImagePickerController. It uses **ARC** and requires **Photos** framework. + +![Screenshot](Screenshot.png "Screenshot") + +## Features +1. Picks multiple photos and videos across albums from user's library. +2. Previews assets by long-press gesture. +3. Filters assets for picking only photos or videos. +4. Filters assets or albums by their properties. +5. Achieves average 5x fps. +6. Conforms UIAppearance Protocol. +7. Conforms UIAccessibility Protocol. +8. Highly customisable. +9. Pure Auto Layout. + +## Release Notes +* [Release Notes](https://github.com/chiunam/CTAssetsPickerController/releases) + +## Minimum Requirement +Xcode 6 and iOS 8. + +## Adding to your project +[CocoaPods](http://cocoapods.org) is a very good library dependencies manager. Just create the Podfile and it does all the remaining works. + +Podfile +```` +platform :ios, '8.0' +pod 'CTAssetsPickerController', '~> 3.0.0-beta.1' +```` + +## Running the demo app + +To run the demo app, you have to run `pod install` and then open `CTAssetsPickerDemo.xcworkspace` +````bash +git clone https://github.com/chiunam/CTAssetsPickerController/ +pod install +```` + +## Usages + +### Import header + +```` objective-c +#import +```` + +### Create and present CTAssetsPickerController + +```` objective-c +// request authorization status +[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status){ + dispatch_async(dispatch_get_main_queue(), ^{ + + // init picker + CTAssetsPickerController *picker = [[CTAssetsPickerController alloc] init]; + + // set delegate + picker.delegate = self; + + // present picker + [self presentViewController:picker animated:YES completion:nil]; + + }); +}]; +```` + +### Implement didFinishPickingAssets delegate + +If the picker is presented by `presentViewController:animated:completion:` method, the delegate is responsible for dismissing the picker when the operation completes. + +```` objective-c +- (void)assetsPickerController:(CTAssetsPickerController *)picker didFinishPickingAssets:(NSArray *)assets; +// assets contains PHAsset objects. +```` + +## Customisation + +Customisation can be done by setting properties or implementating delegate methods. See the demo project for the details. + +### Apperance + +The picker conforms `UIAppearance` protocol. For most UI appearance, (e.g. fonts, buttons, text colors), it can be overridden by setting proper `UIAppearance` after picker initalisation. Please refer to the demo project. + +### Localisation + +`CTAssetsPicker.strings` contains strings used in the picker. It will be included in `CTAssetsPickerController.bundle` if you add the picker to your project by using CocoaPods. You might translate the text accordingly. PR is always welcomed if you add translation of the picker. + +### Notifications + +`NSNotification` objects named `CTAssetsPickerSelectedAssetsDidChangeNotification`, `CTAssetsPickerDidSelectAssetNotification` and `CTAssetsPickerDidDeselectAssetNotification` will be sent when user select or deselect assets. You may add your observer to monitor the change of selection. + +## Bonus + +You may reuse the preview feature of the picker to view any assets. Just init a `CTAssetsPageViewController` with an array of assets and assign `pageIndex` property. Please refer to the demo app for the details. + +```` objective-c +NSArray *assets = @[asset1, asset2, asset3, ...]; +CTAssetsPageViewController *vc = [[CTAssetsPageViewController alloc] initWithAssets:assets]; +vc.pageIndex = assets.count - 1; // display the last asset + +[self.navigationController pushViewController:vc animated:YES]; +```` + + +## Documentation +* [Online documentation](http://cocoadocs.org/docsets/CTAssetsPickerController/) + + +## Note +CTAssetsPickerController does not compress the picked photos and videos. You can retrieve the image or video data of picked assets by the `PHImageManager` object. Please refer the documentation of `PHImageManager`. + + +## License + + The MIT License (MIT) + + Copyright (c) 2013 Clement CN Tsang + + Permission is hereby granted, free of charge, to any person obtaining a copy + of this software and associated documentation files (the "Software"), to deal + in the Software without restriction, including without limitation the rights + to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + copies of the Software, and to permit persons to whom the Software is + furnished to do so, subject to the following conditions: + + The above copyright notice and this permission notice shall be included in + all copies or substantial portions of the Software. + + THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
