UIScrollView 期本使用方法
myScroll=[[UIScrollView alloc] initWithFrame:CGRectMake(50, 120, 617, 131*6)]; myScroll.bounces = YES; //是不有拉申返弹的效果 myScroll.pagingEnabled = YES;//是否分页显示 myScroll.delegate = self;//设定理方法 myScroll.userInteractionEnabled = YES; myScroll.showsHorizontalScrollIndicator=NO;//是否显示水平滑动条 myScroll.showsVerticalScrollIndicator= NO;//是否显示竖直滑动条 //设定scrollView滑动的大小范围 myScroll.contentSize = CGSizeMake(myScroll.frame.size.width * [self.myArray count],myScroll.frame.size.height); [self.view addSubview:myScroll]; [myScroll release]; #pragma mark UIScrollViewDelegate //只要滚动了就会触发 - (void)scrollViewDidScroll:(UIScrollView *)scrollView; { NSLog(@"ContentOffset x is %f,yis %f",scrollView.contentOffset.x,scrollView.contentOffset.y); } //开始拖拽视图 - (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView; { NSLog(@"开始拖拽视图"); } //完成拖拽 - (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate; { NSLog(@"完成拖拽"); } //将开始降速时 - (void)scrollViewWillBeginDecelerating:(UIScrollView *)scrollView; { NSLog(@"将开始降速时"); } //减速停止了时执行,手触摸时执行执行 - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView; { NSLog(@"减速停止了时执行,手触摸时执行执行"); } //滚动动画停止时执行,代码改变时出发,也就是setContentOffset改变时 - (void)scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView; { NSLog(@"滚动动画停止时执行,代码改变时出发,也就是setContentOffset改变时"); } //设置放大缩小的视图,要是uiscrollview的subview - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView; { NSLog(@"设置放大缩小的视图,要是uiscrollview的subview"); return nil; } //完成放大缩小时调用 - (void)scrollViewDidEndZooming:(UIScrollView *)scrollView withView:(UIView *)view atScale:(float)scale; { NSLog(@"s完成放大缩小时调用"); }
如果错过了一天,那么真的就错过一天。不抛弃,不放弃。点一盏心灯给自己。
