NHSlideShow

This control provides varity of animation options to run a slideshow on iphone, ipod and ipad as well. It maintains a circular queue of images.

This control is also available on Cocoacontrols.com: https://www.cocoacontrols.com/controls/nhslideshow

Here is how it looks like:

The attached source code is available for both storyboard and XIBs. On slight modification in code can change the mode from storyboard to XIBs.

How to integrate:

- (void)viewDidLoad
{
     [super viewDidLoad];

      // Create slide show control
      slideShow = [[NHSlideShow alloc] initWithFrame:CGRectMake(0, 0, kScreenSize.height, kScreenSize.width)]; 
     [slideShow setDelayInTransition:2.0f];
     [slideShow setDelegate:self];
     [slideShow slidesWithImages:[self getImages]];
}

-(void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];
    
     // This will help to run the same code on iphone if single layout files 
     // designed for both iphone 4 and iphone 5.
    [slideShow doneLayout];
    
     // Start slide show
    [slideShow start];
}

-(NSArray *)getImages
{
    // Create array of images to be run in slide show
     NSMutableArray *mArr = [[NSMutableArray alloc] init];
    
    [mArr addObject:[UIImage imageNamed:@"1.png"]];
    [mArr addObject:[UIImage imageNamed:@"2.png"]];
    [mArr addObject:[UIImage imageNamed:@"3.png"]];
    
    [mArr addObject:[UIImage imageNamed:@"4.png"]];
    [mArr addObject:[UIImage imageNamed:@"5.png"]];
    [mArr addObject:[UIImage imageNamed:@"6.png"]];
    
    [mArr addObject:[UIImage imageNamed:@"7.png"]];
    [mArr addObject:[UIImage imageNamed:@"8.png"]];
    [mArr addObject:[UIImage imageNamed:@"9.png"]];
    
    [mArr addObject:[UIImage imageNamed:@"10.png"]];    
    
     return mArr;
}
