OCUI界面设计：滚动视图与分页控件初探

滚动视图(UIScrollView) 简单介绍 1.UIScrollView滚动视图能够排列并显示超出自身显示范围的内容. 2.UIScrollView内部整合了多种手势来达到丰富的界面展示效果. 3.UITableView.UITextView都继承于UIScrollView. UIScrollView例子 1.上下滚动:如信息界面或者设置界面. 2.左右滚动:如音乐播放器里面的专辑信息展示. UIScrollView实现机制 1.视图被加入到父视图上进行显示.超出父视图边界的部分将被隐藏.

滚动视图多个页面实现的原理 滚动视图位置不变 内容的位置发生改变. 滚动视图的运用1.分页查看图片 2.查看大图片 3.当内容过多需要一个页面显示,如:注册,修改个人信息等等4.当不希望用户感觉咱们的界面是一张图片的时候...... 设置滚动视图的contentSize 时,如果contentSize小于 滚动视图的bounds就不会滚动 设置滚动视图的contentSize跟图片的尺寸一样 scrollview.contentSize =bgimg.size; 在滚动视图上添加图片 (在滚动视
