ZYQPhotoBrowser ZYQPhotoBrowser ZYQPhotoBrowser

ZYQPhotoBrowser is a new implementation based on MWPhotoBrowser.

We’ve added both user experience and technical features inspired by Facebook’s and Tweetbot’s photo browsers.

Usage

See the code snippet below for an example of how to implement the photo browser.

First create a photos array containing ZYQPhoto objects:

// URLs array
NSArray *photosURL = @[
                      [NSURL URLWithString:@"https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1498113175410&di=bd10bcd2b2a45906259f4e823bbf9df6&imgtype=0&src=http%3A%2F%2Fpic.58pic.com%2F58pic%2F14%2F27%2F45%2F71r58PICmDM_1024.jpg"]
                      ,[NSURL URLWithString:@"https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1498113236506&di=004225eba24d74087feaeaa9484db047&imgtype=0&src=http%3A%2F%2Fic.topit.me%2Fc%2F3c%2Ff6%2F1110230348da8f63cco.jpg"]
                      ,[NSURL URLWithString:@"https://timgsa.baidu.com/timg?image&quality=80&size=b10000_10000&sec=1498103182&di=eb660bada9ced24acbc9153464aaedcd&src=http://www.bz55.com/uploads/allimg/141120/139-141120151946.jpg"]
                      ,[NSURL URLWithString:@"https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1498139264538&di=6e5cedbfecc6a0e4bce2fc0005f56785&imgtype=0&src=http%3A%2F%2Fimg3.a0bi.com%2Fupload%2Fttq%2F20140719%2F1405761279700.gif"]
                      ];

// Create an array to store ZYQPhoto objects
NSMutableArray *photos = [NSMutableArray new];

for (NSURL *url in photosURL) {
    ZYQPhoto *photo = [ZYQPhoto photoWithURL:url];
    [photos addObject:photo];
}

// Or use this constructor to receive an NSArray of ZYQPhoto objects from your NSURL objects
NSArray *photos = [ZYQPhoto photosWithURLs:photosURL];

There are two main ways to presente the photoBrowser, with a fade on screen or with a zooming effect from an existing view.

Using a simple fade transition:

ZYQPhotoBrowser *browser = [[ZYQPhotoBrowser alloc] initWithPhotos:photos];

Zooming effect from a view:

ZYQPhotoBrowser *browser = [[ZYQPhotoBrowser alloc] initWithPhotos:photos animatedFromView:sender];

When using this animation you can set the scaleImage property, in case the image from the view is not the same as the one that will be shown on the browser, so it will dynamically scale it:

browser.scaleImage = buttonSender.currentImage;

Presenting using a modal view controller:

[self presentViewController:browser animated:YES completion:nil];

Customization

Toolbar

You can customize the toolbar. There are three boolean properties you can set: displayActionButton (default is YES), displayArrowButton (default is YES) and displayCounterLabel (default is NO). If you dont want the toolbar at all, you can set displayToolbar = NO.

Toolbar setup example:

browser.displayActionButton = NO;
browser.displayArrowButton = YES;
browser.displayCounterLabel = YES;

It is possible to use your own image on the toolbar arrows:

browser.leftArrowImage = [UIImage imageNamed:@"PhotoBrowser_customArrowLeft.png"];
browser.rightArrowImage = [UIImage imageNamed:@"PhotoBrowser_customArrowRight.png"];
browser.leftArrowSelectedImage = [UIImage imageNamed:@"PhotoBrowser_customArrowLeftSelected.png"];
browser.rightArrowSelectedImage = [UIImage imageNamed:@"PhotoBrowser_customArrowRightSelected.png"];

If you want to use custom actions, set the actionButtonTitles array with the titles for the actionSheet. Then, implement the photoBrowser:didDismissActionSheetWithButtonIndex:photoIndex: method, from the ZYQPhotoBrowser delegate

browser.actionButtonTitles = @[@"Option 1", @"Option 2", @"Option 3", @"Option 4"];

Others

Others customizations you can make are: use white background color, don’t display the done button and change the done button background image:

browser.useWhiteBackgroundColor = YES;
browser.displayDoneButton = NO;
browser.doneButtonImage = [UIImage imageNamed:@"PhotoBrowser_customDoneButton.png"];

If you want to keep the interface shown when the user is scrolling :

browser.autoHideInterface = NO;

You can use a smooth zoom animation when presenting and dismissing a photo:

browser.useZoomAnimation = YES;

If the presenting view controller doesn’t have a status bar, in some cases you can force it to be hidden:

browser.forceHideStatusBar = YES;

It’s possible to disable the vertical dismiss swipe gesture:

browser.disableVerticalSwipe = YES;

Dismiss the photo browser with a touch (instead of showing/hiding controls):

browser.dismissOnTouch = YES;

You can use custom backgroud

browser.customBackgroud=[[BackgroudBlurView alloc] init];

Photo Captions

Photo captions can be displayed simply by setting the caption property on specific photos:

ZYQPhoto *photo = [ZYQPhoto photoWithFilePath:[[NSBundle mainBundle] pathForResource:@"photo2l" ofType:@"jpg"]];
photo.caption = @"Campervan";

No caption will be displayed if the caption property is not set.

Custom Captions

By default, the caption is a simple black transparent view with a label displaying the photo’s caption in white. If you want to implement your own caption view, follow these steps:

  1. Optionally use a subclass of ZYQPhoto for your photos so you can store more data than a simple caption string.
  2. Subclass ZYQCaptionView and override -setupCaption and -sizeThatFits: (and any other UIView methods you see fit) to layout your own view and set it’s size. More information on this can be found in ZYQCaptionView.h
  3. Implement the -photoBrowser:captionViewForPhotoAtIndex: ZYQPhotoBrowser delegate method (shown below).

Example delegate method for custom caption view:

- (ZYQCaptionView *)photoBrowser:(ZYQPhotoBrowser *)photoBrowser captionViewForPhotoAtIndex:(NSUInteger)index {
    ZYQPhoto *photo = [self.photos objectAtIndex:index];
    MyCaptionViewSubclass *captionView = [[MyCaptionViewSubclass alloc] initWithPhoto:photo];
    return captionView;
}

Custom Opensource libraries

You need to implement protocol

//ZYQPhotoBrowser's
@protocol ZYQPhotoBrowserCustomProtocol <NSObject>

@required
- (void)custom_animateView:(UIView *)view toFrame:(CGRect)frame completion:(void (^)(void))completion;

@end

//ZYQPhoto's
@protocol ZYQPhotoCustomLoadProtocol <NSObject>

@required
-(void)loadImageWithURL:(NSURL*)url updateProgressBlock:(void (^)(CGFloat progress))updateProgressBlock completedBlock:(void (^)(UIImage *image,NSError *error))completedBlock;
-(id)loadImageWithFile:(NSString *)path;

@end

//ZYQZoomingScrollView's
@class ZYQPhotoBrowser;
@protocol ZYQZoomingScrollViewCustomProtocol <NSObject>

@required
-(id)getCustomProgressViewWithBrowser:(ZYQPhotoBrowser*)browser;

@end

//Your ProgressView's
@protocol ZYQProgressViewProtocol <NSObject>

@required
@property(nonatomic,assign)CGFloat zyq_progress;

@end

Example

add pod 'YYWebImage' to your Podfile.


@interface ZYQPhoto (Custom)<ZYQPhotoCustomLoadProtocol>

@end

@implementation ZYQPhoto (Custom)

-(void)loadImageWithURL:(NSURL*)url updateProgressBlock:(void (^)(CGFloat progress))updateProgressBlock completedBlock:(void (^)(UIImage *image,NSError *error))completedBlock{
    [[YYWebImageManager sharedManager] requestImageWithURL:url options:YYWebImageOptionAllowBackgroundTask progress:^(NSInteger receivedSize, NSInteger expectedSize) {
        if (updateProgressBlock) {
            updateProgressBlock(receivedSize/expectedSize*1.0);
        }
    } transform:nil completion:^(UIImage * _Nullable image, NSURL * _Nonnull url, YYWebImageFromType from, YYWebImageStage stage, NSError * _Nullable error) {
        if (completedBlock) {
            completedBlock(image,error);
        }
    }];
}

-(id)loadImageWithFile:(NSString *)path{
    return [YYImage imageWithContentsOfFile:path];
}

@end

@interface ZYQZoomingScrollView (Custom)<ZYQZoomingScrollViewCustomProtocol>

@end

@implementation ZYQZoomingScrollView (Custom)

-(id)getCustomProgressViewWithBrowser:(ZYQPhotoBrowser *)browser{
    CGRect screenBound = [[UIScreen mainScreen] bounds];
    CGFloat screenWidth = screenBound.size.width;
    CGFloat screenHeight = screenBound.size.height;

    DACircularProgressView *tmpProgressView = [[DACircularProgressView alloc] initWithFrame:CGRectMake((screenWidth-35.)/2., (screenHeight-35.)/2, 35.0f, 35.0f)];
    [tmpProgressView setProgress:0.0f];
    tmpProgressView.tag = 101;
    tmpProgressView.thicknessRatio = 0.1;
    tmpProgressView.roundedCorners = NO;
    tmpProgressView.trackTintColor    = browser.trackTintColor    ? browser.trackTintColor    : [UIColor colorWithWhite:0.2 alpha:1];
    tmpProgressView.progressTintColor = browser.progressTintColor ? browser.progressTintColor : [UIColor colorWithWhite:1.0 alpha:1];

    _progressView=tmpProgressView;

    return tmpProgressView;
}

@end

@interface DACircularProgressView (Custom)<ZYQProgressViewProtocol>

@end

@implementation DACircularProgressView (Custom)

-(void)setZyq_progress:(CGFloat)zyq_progress{
    [self setProgress:zyq_progress animated:YES];
}

-(CGFloat)zyq_progress{
    return [self progress];
}

@end
