1) Take a project of name GallerySample.
2) drag and drop 5 images in your resource folder with name of image1.jpeg,image2.jpeg,image3.jpeg,image4.jpeg and image5.jpeg.
3) Open ViewController.m and modified the code as follows (Modified code is in different color)
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
UIScrollView *scrollView=[[UIScrollView alloc]initWithFrame:CGRectMake(0, 50, 320, 270)];
// creating a scroll view
[scrollView setPagingEnabled:YES];
// enabled paging of scroll view
[scrollView setShowsHorizontalScrollIndicator:NO];
// disabled sliding bar
NSArray *imageArray=[[NSArray alloc]initWithObjects:@"image1",@"image2",@"image3",@"image4",@"image5", nil];
// creating an array having the name of all images which are to be shown in gallery
for( int i=0; i< [imageArray count];i++)
{
NSString *imageName=[imageArray objectAtIndex:i];
// getting the name of image from array
NSString *fullImageName=[NSString stringWithFormat:@"%@.jpeg",imageName];
// appending extention to the name of image to complete the image name
int padding=25;
// padding is given.
CGRect imageViewFrame=CGRectMake(scrollView.frame.size.width*i+padding, scrollView.frame.origin.y, scrollView.frame.size.width-2*padding, scrollView.frame.size.height);
// Getting frame of image so that all images are not overlapped to each other.
// each frame is distict with other frame
UIImageView *imageView=[[UIImageView alloc]initWithFrame:imageViewFrame];
// Setting frame of imageView
[imageView setImage:[UIImage imageNamed:fullImageName]];
// setting image to the image view
[imageView setContentMode:UIViewContentModeScaleAspectFit];
// setting content mode of image view so that image looks good
[scrollView addSubview:imageView];
// adding image view to the scroll view
}
CGSize scrollViewSize=CGSizeMake(scrollView.frame.size.width*[imageArray count], scrollView.frame.size.height);
// getting the content size of scroll view
[scrollView setContentSize:scrollViewSize];
// setting content size of scroll view
[self.view addSubview:scrollView];
// finally add scroll view to your view
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
Now when you run the code you will get a gallery having 5 images , You can scroll to get all images.
