添加一个按钮来隐藏键盘-百家乐凯发k8

问题描述

在一个uitextview上隐藏键盘，有方法:

on a uitextview to hide the keyboard, there is the method:

...
    textfield.returnkeytype = uireturnkeydone;
    textfield.delegate = self;
....
-(bool)textfieldshouldreturn:(uitextfield *)textfield {
    [textfield resignfirstresponder];
    return yes;
}

但是如果我想将完成"按钮留给返回"并添加一个隐藏键盘的按钮，我该怎么办?

but if i want to leave the button "done" to the "return" and add a button to hide the keyboard, how do i?

推荐答案

您可以分配一个带有按钮的工具栏，该按钮可作为文本字段的 inputaccessoryview 关闭键盘.一个简单的例子是，

you can assign a toolbar with a button that dismisses the keyboard as the text field's inputaccessoryview. a quick example would be,

uibarbuttonitem *barbutton = [[[uibarbuttonitem alloc] initwithbarbuttonsystemitem:uibarbuttonsystemitemdone target:textfield action:@selector(resignfirstresponder)] autorelease];
uitoolbar *toolbar = [[[uitoolbar alloc] initwithframe:cgrectmake(0, 0, 320, 44)] autorelease];
toolbar.items = [nsarray arraywithobject:barbutton];
textfield.inputaccessoryview = toolbar;
