如图中所示 在键盘上面加一条工具栏
大致思路是提前创建好工具栏，在键盘弹出的时候将工具栏显示出来，在键盘消失的时候让工具栏隐藏
上代码
设置两个变量
|
1
2
|
uiview * _toolview; //工具栏
uitextfield *textfield;// 输入框 呼出键盘用
|
创建工具栏 输入框 添加键盘弹出 消失的通知

#pragma mark 当键盘出现或改变时调用
- (void)keyboardwillshow:(nsnotification *)anotification
{
//键盘弹出时显示工具栏
//获取键盘的高度
nsdictionary *userinfo = [anotification userinfo];
nsvalue *avalue = [userinfo objectforkey:uikeyboardframeenduserinfokey];
cgrect keyboardrect = [avalue cgrectvalue];
float keyboardheight = keyboardrect.size.height;
// nslog(@"%ld",(long)keyboardheight);
[uiview animatewithduration:0.1 animations:^{
_toolview.frame = cgrectmake(0, screen_height-keyboardheight-50, screen_width, 50);
}];
}
#pragma mark 当键退出时调用
- (void)keyboardwillhide:(nsnotification *)anotification
{
//键盘消失时 隐藏工具栏
[uiview animatewithduration:0.1 animations:^{
_toolview.frame = cgrectmake(0, screen_height+50, screen_width, 50);
}];
}
