了解iPhone应用中UIScrollView的使用方法是本文要介绍的内容,主要是实现UIScrollView可以产生画轴的效果,可以在手机屏中左右滑动。先来看内容。
初始化代码为:
- mainView = [[UIScrollView alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.frame.size.width, 400)];
- mainView.directionalLockEnabled = YES;
- mainView.pagingEnabled = YES;
- mainView.backgroundColor = [UIColor blueColor];
- mainView.showsVerticalScrollIndicator = NO;
- mainView.showsHorizontalScrollIndicator = NO;
- mainView.delegate = self;
- CGSize newSize = CGSizeMake(self.view.frame.size.width * 2, self.view.frame.size.height);
- [mainView setContentSize:newSize];
- [self.view addSubview:mainView];
- pageControl = [[UIPageControl alloc] initWithFrame:CGRectMake(0.0, 401, self.view.frame.size.width, 80)];
- pageControl.hidesForSinglePage = YES;
- pageControl.userInteractionEnabled = NO;
- pageControl.backgroundColor = [UIColor redColor];
- [self.view addSubview:pageControl];
- UIView *view1=[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.frame.size.width, self.view.frame.size.height)];
- view1.backgroundColor=[UIColor redColor];
- [mainView addSubview:view1];
- UIView *view2=[[UIView alloc] initWithFrame:CGRectMake(self.view.frame.size.width, 0.0, self.view.frame.size.width, self.view.frame.size.height)];
- view2.backgroundColor=[UIColor blueColor];
- [mainView addSubview:view2];
滑动的事件为:
- #pragma mark -
- #pragma mark UIScrollView
- - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{
- if ([scrollView isKindOfClass:[UITableView class]]) {
- return;
- }
- int index = fabs(scrollView.contentOffset.x) / scrollView.frame.size.width;
- pageControl.currentPage = index;
- //index为当前页码
- NSLog(@"%d",index);
- }
小结:了解iPhone应用中UIScrollView的使用方法的内容介绍完了,希望本文对你有所帮助!
