iOS巅峰之键盘回收方法

之前我们想让键盘回收, 需要设置代理, 取消第一响应者, 如果textFeild 太多使用这个方法, 不够简洁

下面介绍下endEditing：方法，该方法为UIView中的一个方法，定义为

官方文档译文:

Causes the view (or one of its embedded text fields) to resign the first responder status.

This method looks at the current view and its subview hierarchy for the text field that is currently the first responder. If it finds one, it asks that text field to resign as first responder. If the force parameter is set
to YES, the text field is never even asked; it is forced to resign.

大意为:

注销当前view(或它下属嵌入的text fields)的first responder 状态。

该方法会在当前view以及其subview层次结构中需找当前处于first responder状态的text field。如果找到的话会注销其first responder状态，如果指定force参数为YES，则不再询问text field，而直接强制注销其first responder状态。

[self.view endEditing:YES];

键盘马上关闭
