iphone - 标签栏中的可扩展中心按钮
原标题:iphone - expandible center button in tabbar

如何执行此操作? 我找到了如何执行自定义中心按钮, 而不是您单击按钮的部分, 并且它会以更多选项扩展 。

如何执行这个计划?

它是一个自定义视图。那里的底边栏可能不是一个制表栏,甚至可能不是一个工具栏。它也可能是一个自定义视图。当您在中心视图上点击时,它会扩展以显示额外内容。

这里似乎有两种观点。

制表栏是 " 制表栏 ",第一个 " 强 ",第一个 " / " 强 " 是制表栏

中键为 < 强 > 秒 1

第二种观点是在第一个观点之上添加的,实际上比屏幕大。

当用户点击箭头时, 动画可能会被执行以显示整个视图 。
