IOS版的一个ViewPager

写了一个IOS版本的ViewPager，效果如图

 UIView* viewFirst = [[UIViewalloc] init];

    viewFirst.backgroundColor = [UIColorgreenColor];

    

   UIView* viewSecond = [[UIViewalloc] init];

    viewSecond.backgroundColor = [UIColorblueColor];

    

   UIView* viewThird = [[UIViewalloc] init];

    viewThird.backgroundColor = [UIColorredColor];

    

   UIView* viewFour = [[UIViewalloc] init];

    viewFour.backgroundColor = [UIColoryellowColor];

    

   NSArray* views = [[NSArrayalloc]initWithObjects:viewFirst,viewSecond,viewThird,viewFour,nil];

   _vp = [[ViewPageralloc]initWithFrame:CGRectMake(0,0, 320, 460) andViews:views];

    

    [self.viewaddSubview:_vp];

如果需要捕捉切换事件，实现ViewPagerDelegate协议

-(void)ViewPager:(ViewPager *)viewPager didSelectIndex:(NSInteger)index

{

   NSLog(@"当前索引：%d",index);

}
