ETFoursquareImages

When you scroll, image's shown area will become bigger. Like it appears on places' page in Foursquare app.

Requirements

• Xcode 5.
• iOS 6 or later.
• ARC.

How to use

ETFoursquareImages is a simple UIScrollView with images on the top of this UIScrollView.

Include the ETFoursquareImages.h and ETFoursquareImages.m in your project.

To display ETFoursquareImages, simply do it like basic UIVIew's initWithFrame:

ETFoursquareImages *foursquareImages = [[ETFoursquareImages alloc] initWithFrame:CGRectMake(0, 0, 320, self.view.frame.size.height)];
[self.view addSubview:foursquareImages];

Then you should set images' height and images array. I recommend you to set image's height about 160 pixels:

int imagesHeight = 160;
[foursquareImages setImagesHeight:imagesHeight];
NSArray *images  = [NSArray arrayWithObjects:[UIImage imageNamed:@"horses"], [UIImage imageNamed:@"surfer"], [UIImage imageNamed:@"bridge"], nil];
[foursquareImages setImages:images];

When you add subview or set scrollView's content size don't forget about images height.

UITextView *hintTextView = [[UITextView alloc] initWithFrame:CGRectMake(0, imagesHeight+10, 320, 110)];
hintTextView.text = @"When you scroll, image's shown area will become bigger. Like it appears on place's page in Foursquare app.";
[foursquareImages.scrollView addSubview:hintTextView];

foursquareImages.scrollView.contentSize = CGSizeMake(320, 110+imagesHeight);

You can adapt scroll view, page control and and view below images (bottomView) through this variables:

@property (nonatomic, strong) UIPageControl *pageControl;
@property (nonatomic) int pageControlHeight;

@property (nonatomic, strong) UIScrollView *scrollView;
@property (nonatomic, strong) UIView *bottomView;
