When I want to use the paging component of UIScrollView, I found that there is no suitable. So I wrote a custom paging components, it is very convenient to use very simple. Now shared to you, you can also give me some advice, thank you for using!!!
//选中的图片是点
self.pageControl = [[MDPageControl alloc] initWithType:self.scrollView type:MDPointTypePoint];
//选中的图片是块
// self.pageControl = [[MDPageControl alloc] initWithType:self.scrollView type:MDPointTypeBlock];
//默认选中的图片是点
// self.pageControl = [[MDPageControl alloc] initWithScrollView:self.scrollView];
//默认选中的图片是点, 并且设置pageControllView离scrollView底部的距离，默认为25
// self.pageControl = [[MDPageControl alloc] initWithBottomPadding:self.scrollView padding:25];
//设置选中的图片是点或者块, 并且设置pageControllView离scrollView底部的距离，默认为25
// self.pageControl = [[MDPageControl alloc] initWithTypeAndBottomPadding:self.scrollView type:MDPointTypeBlock padding:25];
//设置自定义图片，图片大小可参照我提供的图片大小 2x(14x14) 1x(7x7) 3x(21x21)
// self.pageControl = [[MDPageControl alloc] initWithPointImages:self.scrollView normalImage:@"point_normal" selectedImage:@"point_selected"];
//设置自定义图片，并设置pageControllView离scrollView底部的距离，默认为25
// self.pageControl = [[MDPageControl alloc] initWithPointImagesAndPadding:self.scrollView normalImage:@"point_normal" selectedImage:@"point_selected" padding:25];
//设置分页数
[self.pageControl setPageNum:3];
//显示pageControllView
[self.pageControl show]; //点击小点block
[self.pageControl didSelectMDPageIndexBlock:^(NSInteger pageIndex) {
[self.scrollView scrollRectToVisible:CGRectMake(pageIndex*SCREEN_WIDTH, 0, SCREEN_WIDTH, 175.f) animated:YES];
}]; //可以设置delegate，当点击小点时，执行delegate方法
self.pageControl.delegate = self;
//MDPageControlDelegate 方法
- (void)didSelectMDPageIndex:(NSInteger)pageIndex {
[self.scrollView scrollRectToVisible:CGRectMake(pageIndex*SCREEN_WIDTH, 0, SCREEN_WIDTH, 175.f) animated:YES];
}If you want to change the distance between points, you can modify the MDPageControl.h file
//distance between points
//圆点之间的间距
#define POINT_DISTANCE 10.f
