DXImagePicker

Simple Imager picker which mimic Facebook's UI and UX

###Demo

###Purpose

We wanna an image picker which contains both camera capture and albums selection(indexed) in a single view controller, just one that does not include push and present other stuff. Like facebook's app does! So, here comes this project.

###How to use

1. Drop DXImagePicker into your project and #import "DXImagePicker.h" somewhere you need

2. In some your viewController method, doing this:

    // present the picker and set the delegate, note: you'd better present not push.
    - (void)presentPhotoSelectBrowser
    {
        DXImagePicker *browser = [DXImagePicker new];
        browser.delegate = self;
        UINavigationController *navcon = [[UINavigationController alloc] initWithRootViewController:browser];
        [self presentViewController:navcon animated:YES completion:nil];
    }
   
    // implement the delegate method, and update your UI
    - (void)dx_imagePickerController:(DXImagePicker *)picker didSelectAssets:(NSArray *)assets didCamptureImage:(UIImage *)image
    {
    
        [self.images removeAllObjects];
        [self.collectionView reloadData];
        
        
        for (ALAsset *asset in assets) {
            UIImage *thumbnail = [[UIImage alloc] initWithCGImage:asset.thumbnail];
            [self.images addObject:thumbnail];
        }
        
        if (image) {
            [self.images addObject:image];
        }
        
        
        [self.collectionView reloadData];
        self.selectedAssetNames = [DXImagePicker getAssetNamesByAssets:assets];
    }
   

3. If you don't need to let the user continue to choosing on last choosen state, that's all. But if you did, here's some property need to be set.

    //Before presenting imagePicker, you need set this. Where does it come from?
    dx_imagePickerController:didSelectAssets:didCamptureImage: this delegate return the assets, you need to hold the [DXImagePicker getAssetNamesByAssets:assets] assets names; and set that to this property.
   
    @property (nonatomic, strong) NSArray *shouldSelectedAssetFileNames;
   
   
    //dx_imagePickerController:didSelectAssets:didCamptureImage: callback this, and also you need an ivar to hold it, next time you present the imagePicker, set this property.
    		
    @property (nonatomic, strong) NSString *shouldSelectAlbumName;
