but i need to display while incrementing the label count then automatically increments images one by one.like this
Can you please help me how can i implement,thank you.

Answer 1

Add a UIScrollView in place of where you want to show images. When click on '+' button, call following method by passing the 'counter' value.
-(void)addImage:(int) count {
UIScrollView * scView = [[UIScrollView alloc] init];
scView.frame = CGRectMake(30, 60, self.view.frame.size.width, 60);
UIButton * btn;
UIImageView * imgV;
float imgWidth = 44;
for(int i=0;i<count;i++) {
imgV = [[UIImageView alloc] init];
imgV.frame = CGRectMake(i*imgWidth, 0, imgWidth, 44);
imgV.image = [UIImage imageNamed:#"gitar"];
[scView addSubview:imgV];
}
[scView setContentSize:CGSizeMake(imgWidth*count, 50)];
[scView setBackgroundColor:[UIColor redColor]];
[self.view addSubview:scView];
}
- (IBAction)descrese:(id)sender {
counter -= 1;
[self addImage:counter];
}
- (IBAction)btnTap:(id)sender {
counter += 1;
[self addImage:counter];
}
This adds as many images as you want in horizontal scroll view.

Answer 2

use a uiscrollview with cells of images, that simple.

Answer 3

Use UIScrollView.
As number of elements is increasing/decreasing:
1) increse/deacrease UIScrollView size respectively
2) add/remove elements

Answer 4

I guess, the screenshot was taken from MMT app. They're using this feature in their app. I believe, they might have developed a separate control to handle this thing, where they can only pass few arguments like image to show (people), count etc.
You can also develop such kind of UI with following way:
Create a custom view, take a UICollectionView inside it, take argument of image to show and number of rows count, fixed the cell size in layouts. Add a method which will reloads UI (inside logic: reloading UICollectionView) to refresh content when user taps on [ + ] or [ - ] button. Why, we're not taking UIScrollView, with it we can't reuse contents. I believe this step will need you to create everything programmatically.
When user taps on [ + ], you should increase width of our custom view, inside
you should override layoutSubview method to update frame of UICollectionView as well. You may require to refresh(reload) cells inside UICollectionView.
Do reverse when user taps [ - ].
You may require to set some logic so user can't add more/less numbers when selection.
This is just an idea, you may require to check each cases which the reference app has having.
