Answer 1

You could do as below:-
Firstly, create a UIImageView property like below,
#property (nonatomic,weak) IBOutlet UIImageView *imageView; //Also connect it with storyboard or xib.
Then you could write down IBAction as follow:-
- (IBAction)startTap:(id)sender {
[self.imageView setAnimationDuration:1.0f]; //You could change the duration for making animation fast or slow.
[self.imageView setAnimationImages:imageArray]; //imageArray is NSArray of images of which you want to show slide show.
[self.imageView startAnimating]; //simply to start animation.
}
- (IBAction)stopTap:(id)sender {
[self.imageView stopAnimating]; //To stop animation.
}

try this..
create two instance objects like
NSMutableArray * imagesArray; and UIImageView *animationImageView;
-(void)viewDidLoad
{
NSArray *imageNames = #[#"img1.png", #"img2.png", #"img3.png", #"img4.png",#"img5.png"];
imagesArray = [[NSMutableArray alloc]init];
NSMutableArray *images = [[NSMutableArray alloc] init];
for (int i = 0; i < imageNames.count; i++)
{
[imagesArray addObject:[UIImage imageNamed:[imageNames objectAtIndex:i]]];
}
animationImageView = [[UIImageView alloc] initWithFrame:CGRectMake(60, 95, 86, 193)];
animationImageView.animationImages = imagesArray;
animationImageView.animationDuration = 0.5; // set your own
[self.view addSubview:animationImageView];
}
and to start and stop two UIButton Actions
-(IBAction)startAnimation:(UIButton*)sender
{
[animationImageView startAnimating];
}
-(IBAction)stopAnimation:(UIButton*)sender
{
[animationImageView stopAnimating];
}
