主要是實現(xiàn)UIScrollView可以產(chǎn)生畫軸的效果,可以在手機屏中左右滑動。先來看內(nèi)容。
初始化代碼為:
mainView = [[UIScrollView alloc] initWithframe:CGRectMake(0.0, 0.0, self.view.frame.size.width, 400)];
mainView.directionalLockEnab
LED = 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];
滑動的事件為:
#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為當(dāng)前頁碼
NSLog(@"%d",index);
