PageView slideshow - ios

Question

I'm new here and could use some help, i'm making an ios app for the ipad and want to be able to animate the transition of pages in a pageview with custom and/or stock transitions.
What is the correct way to animate through various pages (PageView) each having full screen photos in them? Similar to in apples photos app. I'd like to be able to set up a basic slideshow and transition through them.
All Help is appreciated.
Thank You
Edit: Wow those responses were fast, is it also possible to have custom animations?

Answer 1

you can create like this way:-
- (void)viewDidLoad {
[super viewDidLoad];
UIScrollView *scr=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
scr.tag = 1;
scr.autoresizingMask=UIViewAutoresizingNone;
[self.view addSubview:scr];
[self setupScrollView:scr];
UIPageControl *pgCtr = [[UIPageControl alloc] initWithFrame:CGRectMake(0, 264, 480, 36)];
[pgCtr setTag:12];
pgCtr.numberOfPages=10;
pgCtr.autoresizingMask=UIViewAutoresizingNone;
[self.view addSubview:pgCtr];
}
- (void)setupScrollView:(UIScrollView*)scrMain {
// we have 10 images here.
// we will add all images into a scrollView & set the appropriate size.
for (int i=1; i<=10; i++) {
// create image
UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:#"sti%02i.jpeg",i]];
// create imageView
UIImageView *imgV = [[UIImageView alloc] initWithFrame:CGRectMake((i-1)*scrMain.frame.size.width, 0, scrMain.frame.size.width, scrMain.frame.size.height)];
// set scale to fill
imgV.contentMode=UIViewContentModeScaleToFill;
// set image
[imgV setImage:image];
// apply tag to access in future
imgV.tag=i+1;
// add to scrollView
[scrMain addSubview:imgV];
}
// set the content size to 10 image width
[scrMain setContentSize:CGSizeMake(scrMain.frame.size.width*10, scrMain.frame.size.height)];
// enable timer after each 2 seconds for scrolling.
[NSTimer scheduledTimerWithTimeInterval:2 target:self selector:#selector(scrollingTimer) userInfo:nil repeats:YES];
}
- (void)scrollingTimer {
// access the scroll view with the tag
UIScrollView *scrMain = (UIScrollView*) [self.view viewWithTag:1];
// same way, access pagecontroll access
UIPageControl *pgCtr = (UIPageControl*) [self.view viewWithTag:12];
// get the current offset ( which page is being displayed )
CGFloat contentOffset = scrMain.contentOffset.x;
// calculate next page to display
int nextPage = (int)(contentOffset/scrMain.frame.size.width) + 1 ;
// if page is not 10, display it
if( nextPage!=10 ) {
[scrMain scrollRectToVisible:CGRectMake(nextPage*scrMain.frame.size.width, 0, scrMain.frame.size.width, scrMain.frame.size.height) animated:YES];
pgCtr.currentPage=nextPage;
// else start sliding form 1 :)
} else {
[scrMain scrollRectToVisible:CGRectMake(0, 0, scrMain.frame.size.width, scrMain.frame.size.height) animated:YES];
pgCtr.currentPage=0;
}
}
You can use:-
SDWebimage
AFNetworking
NSCache and use of NSCache
For image cache and asynchronous load image
UPDATE:-
Here Bellow is some Library that doing something like photo gallery slide show check this and if you want then use in to you project by reading How to Implement.
