iOS自定义PageControl的方法示例

//创建pageControl
XHPageControl *_pageControl = [[XHPageControl alloc] initWithFrame:CGRectMake(0, 300,[UIScreen mainScreen].bounds.size.width, 30)];
//设置点的总个数
_pageControl.numberOfPages = 7;
//设置非选中点的宽度是高度的倍数(设置长条形状)
_pageControl.otherMultiple = 2;
//设置选中点的宽度是高度的倍数(设置长条形状)
_pageControl.currentMultiple = 4;
//设置样式.默认居中显示
_pageControl.type = PageControlLeft;
//非选中点的颜色 
_pageControl.otherColor=[UIColor grayColor];
//选中点的颜色 
_pageControl.currentColor=[UIColor orangeColor];
//代理 
_pageControl.delegate = self;
//标记 
_pageControl.tag = 902;
 
[self.view addSubview:_pageControl];

#pragma mark - 代理
-(void)xh_PageControlClick:(XHPageControl*)pageControl index:(NSInteger)clickIndex{

 NSLog(@"%ld",clickIndex);
 if(pageControl.tag == 902){
  CGPoint position = CGPointMake([UIScreen mainScreen].bounds.size.width * clickIndex, 0);
  [_scrollView2 setContentOffset:position animated:YES];
 }
}
