Search Bars（一）

A search bar provides an interface for text-based searches with a text box and buttons such as search and cancel. A search bar
accepts text from users, which can be used as input for a search (shown here with placeholder text). A scope bar, which is available only in conjunction with a search bar—allows users to define the scope of a search (shown here below a search bar).

search bar提供了一个带有搜索、取消按钮以及文本框的基于文本搜索的界面。search bar接收用户输入的文本，用这些文本来作为搜索条件进行搜索（在这里显示为占位符）。scope
bar，它只能连同search bar一起显示，允许用户定义搜索范围（下面显示就是一个search bar）。

Purpose. Search bars allow users to:

  • Quickly find a value in a large collection
  • 在一个大的集合里面快速查找某个值
  • Create a scope filter
  • 创建一个范围过滤器

Implementation. Search
bars are implemented in the UISearchBar class
and discussed in the UISearchBar
Class Reference.

详解 UIView 的 Tint Color 属性

在iOS 7后,UIView新增加了一个tintColor属性,这个属性定义了一个非默认的着色颜色值,其值的设置会影响到以视图为根视图的整个视图层次结构.它主要是应用到诸如app图标.导航栏.按钮等一些控件上,以获取一些有意思的视觉效果. tintColor属性的声明如下: var tintColor: UIColor! 默认情况下,一个视图的tintColor是为nil的,这意味着视图将使用父视图的tint color值.当我们指定了一个视图的tintColor后,这个色值会自动传播到视图层次
