Usage

Installation

Using CocoaPods

pod 'GMImagePicker', '~> 0.0.2'

If you don't know yet what CocoaPods is, you should ASAP. It is the standard dependency manager for iOS projects. You can read a good tutorial by Ray Wenderlich here

Manually

Download and import GMImagePicker folder into your project.

Import header file

#import "GMImagePickerController.h"

Initialize the picker, set the delegate and present it.

	GMImagePickerController *picker = [[GMImagePickerController alloc] init];
    picker.delegate = self;
    [self presentViewController:picker animated:YES completion:nil];

Delegate

Implement the GMImagePickerControllerDelegate protocol in your class

@interface YourViewController : UIViewController <GMImagePickerControllerDelegate>

Implement the didFinishPickingAssets delegate method. Note you are responsible for dismissing the picker when the operation completes and process the returned (NSArray *)assetArray :

- (void)assetsPickerController:(GMImagePickerController *)picker didFinishPickingAssets:(NSArray *)assetArray
{
    [picker.presentingViewController dismissViewControllerAnimated:YES completion:nil];
    NSLog(@"GMImagePicker: User ended picking assets. Number of selected items is: %lu", (unsigned long)assetArray.count);
}

You can also implement optional assetsPickerControllerDidCancel

-(void)assetsPickerControllerDidCancel:(GMImagePickerController *)picker
{
    NSLog(@"GMImagePicker: User pressed cancel button");
}

Customization

Before presenting the picker, you can customize some of its properties

    ...
    //Display or not the selection info Toolbar:
    picker.displaySelectionInfoToolbar = YES;

    //Display or not the number of assets in each album:
    picker.displayAlbumsNumberOfAssets = YES;
   
    //Customize the picker title and prompt (helper message over the title)
    picker.title = @"Custom title";
    picker.customNavigationBarPrompt = @"Custom helper message!";

    //Customize the number of cols depending on orientation and the inter-item spacing
    picker.colsInPortrait = 3;
    picker.colsInLandscape = 5;
    picker.minimumInteritemSpacing = 2.0;

    //You can pick the smart collections you want to show:
    _customSmartCollections = @[@(PHAssetCollectionSubtypeSmartAlbumFavorites),
                                @(PHAssetCollectionSubtypeSmartAlbumRecentlyAdded),
                                @(PHAssetCollectionSubtypeSmartAlbumVideos),
                                @(PHAssetCollectionSubtypeSmartAlbumSlomoVideos),
                                @(PHAssetCollectionSubtypeSmartAlbumTimelapses),
                                @(PHAssetCollectionSubtypeSmartAlbumBursts),
                                @(PHAssetCollectionSubtypeSmartAlbumPanoramas)];


    //Disable multiple selecion
    picker.allowsMultipleSelection = NO;

    //Show a promt to confirm single selection
    picker.confirmSingleSelection = YES;
    picker.confirmSingleSelectionPrompt = @"Do you want to select the image you have chosen?";
    
    //Camera integration
    picker.showCameraButton = YES;
    picker.autoSelectCameraImages = YES;
    
    //Select the media types you want to show and filter out the rest
    picker.mediaTypes = @[@(PHAssetMediaTypeImage)];

    //UI color & text customizations
    picker.pickerBackgroundColor = [UIColor blackColor];
    picker.pickerTextColor = [UIColor whiteColor];
    picker.toolbarBarTintColor = [UIColor darkGrayColor];
    picker.toolbarTextColor = [UIColor whiteColor];
    picker.toolbarTintColor = [UIColor redColor];
    picker.navigationBarBackgroundColor = [UIColor blackColor];
    picker.navigationBarTextColor = [UIColor whiteColor];
    picker.navigationBarTintColor = [UIColor redColor];
    picker.pickerFontName = @"Verdana";
    picker.pickerBoldFontName = @"Verdana-Bold";
    picker.pickerFontNormalSize = 14.f;
    picker.pickerFontHeaderSize = 17.0f;
    picker.pickerStatusBarStyle = UIStatusBarStyleLightContent;
    picker.useCustomFontForNavigationBar = YES;
    ...

Use it as popover on iPad

Also works as Popover on the iPad! (with customizable size)

This code works in both iPhone & iPad

    ...
    GMImagePickerController *picker = [[GMImagePickerController alloc] init];
    picker.delegate = self;
    
    picker.title = @"Custom title";
    picker.customNavigationBarPrompt = @"Custom helper message!";
    picker.colsInPortrait = 3;
    picker.colsInLandscape = 5;
    picker.minimumInteritemSpacing = 2.0;
    picker.modalPresentationStyle = UIModalPresentationPopover;
    
    UIPopoverPresentationController *popPC = picker.popoverPresentationController;
    popPC.permittedArrowDirections = UIPopoverArrowDirectionAny;
    popPC.sourceView = _gmImagePickerButton;
    popPC.sourceRect = _gmImagePickerButton.bounds;
    
    [self showViewController:picker sender:nil];
