- Implement the required data source methods to provide the number of pages and the content of each page:
- Implement the optional delegate methods to handle events such as page change:
- You can customize the appearance and behavior of the pager view by using its properties and methods.
#import <DMPagerView/DMPagerView.h>
DMPagerView *pagerView = [[DMPagerView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:pagerView];
pagerView.dataSource = self;
pagerView.delegate = self;
- (NSInteger)numberOfPagesInPagerView:(DMPagerView *)pagerView {
// Return the total number of pages
}
- (UIViewController *)pagerView:(DMPagerView *)pagerView viewControllerForPageAtIndex:(NSInteger)index {
// Return the view controller for a particular page index
}
- (void)pagerView:(DMPagerView *)pagerView didScrollToPageAtIndex:(NSInteger)index {
// Handle page change event
}

}
- (UIViewController *)pagerView:(DMPagerView *)pagerView viewControllerForPageAtIndex:(NSInteger)index {
ImageViewController *imageVC = [[ImageViewController alloc] initWithImage:self.images[index]];
return imageVC;
}
// Implement delegate method to customize the appearance of page indicator
- (UIView *)pagerView:(DMPagerView *)pagerView customPageIndicatorViewForPageAtIndex:(NSInteger)index {
CustomPageIndicatorView *indicatorView = [[CustomPageIndicatorView alloc] init];
UIColor *indicatorColor = [self indicatorColorForPageAtIndex:index];
indicatorView.backgroundColor = indicatorColor;
return indicatorView;
}
