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;
