這篇文章主要為大家詳細(xì)介紹了iOS鍵盤如何添加隱藏鍵盤功能，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了iOS添加隱藏鍵盤功能的具體方法，供大家參考，具體內(nèi)容如下

鍵盤添加個(gè)隱藏鍵盤功能

使用方法：導(dǎo)入XMCustomKeyBoard.h
[XMCustomKeyBoard CancelableKeyboard:控件對象 ];
控件對象可以是UITextFiled,UITextView,UISearchBar 等一系列調(diào)用鍵盤輸入的類的實(shí)例

1.自定義個(gè)UIBarButtonItem，添加屬性editableView，editableView存儲需要添加隱藏鍵盤功能的那個(gè)控件

#import <UIKit/UIKit.h>

@interface XMCustomKeyBoardBtn : UIBarButtonItem
@property (strong, nonatomic) id editableView;

@end

#import "XMCustomKeyBoardBtn.h"

@implementation XMCustomKeyBoardBtn


@end

2.自定義個(gè)UIView，因?yàn)橹挥蠻IView的子類才可以添加進(jìn)keyWindow,想動態(tài)綁定這個(gè)類定義的方法,就必須讓這個(gè)類保持活躍。

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#import "XMCustomKeyBoardBtn.h"


@interface XMCustomKeyBoard : UIView

+ (void) CancelableKeyboard:(id) editableView;

+ (void) CancelableKeyboard:(id) editableView CustomButtonItem:(UIBarButtonItem *)btn;

@end

3.通過傳進(jìn)來的控件為其在鍵盤工具欄添加一個(gè)隱藏鍵盤的按鈕并動態(tài)綁定一個(gè)隱藏鍵盤的方法

#import "XMCustomKeyBoard.h"

@implementation XMCustomKeyBoard

+ (void) CancelableKeyboard:(id) editableView{
  XMCustomKeyBoard *custom = [[XMCustomKeyBoard alloc] initWithFrame:CGRectMake(0,-999,10,10)];
  [[UIApplication sharedApplication].keyWindow addSubview:custom];
  [editableView setInputAccessoryView:[self CancelableKeyboardToolBar:editableView addTarget:custom]];
}

+ (void) CancelableKeyboard:(id) editableView CustomButtonItem:(UIBarButtonItem *)btn {
  XMCustomKeyBoard *custom = [[XMCustomKeyBoard alloc] initWithFrame:CGRectMake(0,-10,10,10)];
  [[UIApplication sharedApplication].keyWindow addSubview:custom];
  [editableView setInputAccessoryView:[self CancelableKeyboardToolBar:editableView CustomButtonItem:btn addTarget:custom]];
}

+ (UIToolbar *)CancelableKeyboardToolBar:(id) editableView CustomButtonItem:(UIBarButtonItem *)btn addTarget:(id) target
{
  UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth([UIApplication sharedApplication].keyWindow.frame), 40)];
  toolbar.backgroundColor = [UIColor lightGrayColor];
  
  UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithTitle:@" " style:UIBarButtonItemStylePlain target:editableView action:@selector(onClick)];
  [button setWidth:[UIApplication sharedApplication].keyWindow.frame.size.width - btn.width];

  XMCustomKeyBoardBtn *button1 = (XMCustomKeyBoardBtn *)btn;
  
  button1.target = target;
  
  button1.action = @selector(CancelableKeyboard:);
  
  button1.editableView = editableView;
         
  [toolbar setItems:@[button,button1]];
  return toolbar;
}

+ (UIToolbar *)CancelableKeyboardToolBar:(id) editableView addTarget:(id) target
{
  UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth([UIApplication sharedApplication].keyWindow.frame), 40)];
  toolbar.backgroundColor = [UIColor lightGrayColor];
  
  UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithTitle:@" " style:UIBarButtonItemStylePlain target:editableView action:@selector(onClick)];
  [button setWidth:[UIApplication sharedApplication].keyWindow.frame.size.width - 50];

  XMCustomKeyBoardBtn *button1 = [[XMCustomKeyBoardBtn alloc] initWithTitle:@"隱藏鍵盤" style:UIBarButtonItemStyleBordered target:target action:@selector(CancelableKeyboard:)];
  
  button1.editableView = editableView;
         
  [button1 setWidth:50];
  [toolbar setItems:@[button,button1]];
  return toolbar;
}
-(void)CancelableKeyboard:(XMCustomKeyBoardBtn *) btn{
  [btn.editableView resignFirstResponder];
}
-(void) onClick{
  
}

@end
