 ios中 键盘 keyboard 上怎么添加工具栏

iOS中键盘 KeyBoard 上添加工具栏的方法

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

- (void)viewdidload {
 [super viewdidload];
 // do any additional setup after loading the view, typically from a nib.
 textfield = [[uitextfield alloc]initwithframe:cgrectmake(10, 64, 120, 60)];
 textfield.placeholder = @"测试";
 [self.view addsubview:textfield];
 //增加监听,当键盘出现或改变时收出消息
 [[nsnotificationcenter defaultcenter] addobserver:self
            selector:@selector(keyboardwillshow:)
             name:uikeyboardwillshownotification
            object:nil];
 //增加监听,当键退出时收出消息
 [[nsnotificationcenter defaultcenter] addobserver:self
            selector:@selector(keyboardwillhide:)
             name:uikeyboardwillhidenotification object:nil];
 //初始化工具栏
 _toolview = [[uiview alloc]init];
 _toolview.frame = cgrectmake(0, screen_height, screen_width, 50);
 [self.view addsubview:_toolview];
 uibutton *losebtn = [uibutton buttonwithtype:uibuttontypecustom];
 losebtn.frame = cgrectmake(20, 0, 50, 50);
 [losebtn addtarget:self action:@selector(btnclick) forcontrolevents:uicontroleventtouchupinside];
 [losebtn settitlecolor:[uicolor blackcolor] forstate:uicontrolstatenormal];
 [losebtn settitle:@"收起" forstate:uicontrolstatenormal];
 [_toolview addsubview:losebtn];
 uibutton *imagebtn = [uibutton buttonwithtype:uibuttontypecustom];
 [imagebtn settitle:@"图片" forstate:uicontrolstatenormal];
 imagebtn.frame = cgrectmake(screen_width-100, 0, 50, 50);
 [imagebtn settitlecolor:[uicolor blackcolor] forstate:uicontrolstatenormal];
 [imagebtn addtarget:self action:@selector(imagebtnclick) forcontrolevents:uicontroleventtouchupinside];
 [_toolview addsubview:imagebtn];
 uibutton *camerabtn = [uibutton buttonwithtype:uibuttontypecustom];
 [camerabtn settitle:@"相机" forstate:uicontrolstatenormal];
 camerabtn.frame = cgrectmake(screen_width-50, 0, 50, 50);
 [camerabtn settitlecolor:[uicolor blackcolor] forstate:uicontrolstatenormal];
 [camerabtn addtarget:self action:@selector(camerabtnclick) forcontrolevents:uicontroleventtouchupinside];
 [_toolview addsubview:camerabtn];
 uibutton *canclebtn = [uibutton buttonwithtype:uibuttontypecustom];
 [canclebtn settitle:@"取消" forstate:uicontrolstatenormal];
 canclebtn.frame = cgrectmake(screen_width-150, 0, 50, 50);
 [canclebtn settitlecolor:[uicolor blackcolor] forstate:uicontrolstatenormal];
 [canclebtn addtarget:self action:@selector(canclebtnbtnclick) forcontrolevents:uicontroleventtouchupinside];
 [_toolview addsubview:canclebtn];
}

#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);
 }];
}

给工具栏上的各个按钮实现点击事件

- (void)btnclick{
 [textfield resignfirstresponder];
}
- (void)imagebtnclick{
}
- (void)camerabtnclick{
}
- (void)canclebtnbtnclick{
}

ps:下面看下ios 键盘上方增加工具栏的代码。

具体代码如下所示:

uitoolbar *keyboarddonebuttonview = [[uitoolbar alloc] init];

uibarbuttonitem *donebutton = [[uibarbuttonitem alloc] initwithtitle:@"done"
                style:uibarbuttonitemstylebordered target:self
                action:@selector(doneclicked:)];
[keyboarddonebuttonview setitems:[nsarray arraywithobjects:donebutton, nil]];
txtfield.inputaccessoryview = keyboarddonebuttonview;
