這篇文章主要為大家詳細介紹了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，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了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

鍵盤添加個隱藏鍵盤功能

使用方法：導入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例

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

#import <UIKit/UIKit.h>

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

@end

#import "XMCustomKeyBoardBtn.h"

@implementation XMCustomKeyBoardBtn


@end

2.自定義個UIView，因為只有UIView的子類才可以添加進keyWindow,想動態(tài)綁定這個類定義的方法,就必須讓這個類保持活躍。

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

#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
