iOS键盘如何添加隐藏键盘功能
本文实例为大家分享了iOS添加隐藏键盘功能的具体方法，供大家参考，具体内容如下
键盘添加个隐藏键盘功能
使用方法：导入XMCustomKeyBoard.h
[XMCustomKeyBoardCancelableKeyboard:控件对象];
控件对象可以是UITextFiled,UITextView,UISearchBar等一系列调用键盘输入的类的实例
1.自定义个UIBarButtonItem，添加属性editableView，editableView存储需要添加隐藏键盘功能的那个控件
#import@interfaceXMCustomKeyBoardBtn:UIBarButtonItem @property(strong,nonatomic)ideditableView; @end
#import"XMCustomKeyBoardBtn.h" @implementationXMCustomKeyBoardBtn @end
2.自定义个UIView，因为只有UIView的子类才可以添加进keyWindow,想动态绑定这个类定义的方法,就必须让这个类保持活跃。
#import#import #import"XMCustomKeyBoardBtn.h" @interfaceXMCustomKeyBoard:UIView +(void)CancelableKeyboard:(id)editableView; +(void)CancelableKeyboard:(id)editableViewCustomButtonItem:(UIBarButtonItem*)btn; @end
3.通过传进来的控件为其在键盘工具栏添加一个隐藏键盘的按钮并动态绑定一个隐藏键盘的方法
#import"XMCustomKeyBoard.h"
@implementationXMCustomKeyBoard
+(void)CancelableKeyboard:(id)editableView{
XMCustomKeyBoard*custom=[[XMCustomKeyBoardalloc]initWithFrame:CGRectMake(0,-999,10,10)];
[[UIApplicationsharedApplication].keyWindowaddSubview:custom];
[editableViewsetInputAccessoryView:[selfCancelableKeyboardToolBar:editableViewaddTarget:custom]];
}
+(void)CancelableKeyboard:(id)editableViewCustomButtonItem:(UIBarButtonItem*)btn{
XMCustomKeyBoard*custom=[[XMCustomKeyBoardalloc]initWithFrame:CGRectMake(0,-10,10,10)];
[[UIApplicationsharedApplication].keyWindowaddSubview:custom];
[editableViewsetInputAccessoryView:[selfCancelableKeyboardToolBar:editableViewCustomButtonItem:btnaddTarget:custom]];
}
+(UIToolbar*)CancelableKeyboardToolBar:(id)editableViewCustomButtonItem:(UIBarButtonItem*)btnaddTarget:(id)target
{
UIToolbar*toolbar=[[UIToolbaralloc]initWithFrame:CGRectMake(0,0,CGRectGetWidth([UIApplicationsharedApplication].keyWindow.frame),40)];
toolbar.backgroundColor=[UIColorlightGrayColor];
UIBarButtonItem*button=[[UIBarButtonItemalloc]initWithTitle:@""style:UIBarButtonItemStylePlaintarget:editableViewaction:@selector(onClick)];
[buttonsetWidth:[UIApplicationsharedApplication].keyWindow.frame.size.width-btn.width];
XMCustomKeyBoardBtn*button1=(XMCustomKeyBoardBtn*)btn;
button1.target=target;
button1.action=@selector(CancelableKeyboard:);
button1.editableView=editableView;
[toolbarsetItems:@[button,button1]];
returntoolbar;
}
+(UIToolbar*)CancelableKeyboardToolBar:(id)editableViewaddTarget:(id)target
{
UIToolbar*toolbar=[[UIToolbaralloc]initWithFrame:CGRectMake(0,0,CGRectGetWidth([UIApplicationsharedApplication].keyWindow.frame),40)];
toolbar.backgroundColor=[UIColorlightGrayColor];
UIBarButtonItem*button=[[UIBarButtonItemalloc]initWithTitle:@""style:UIBarButtonItemStylePlaintarget:editableViewaction:@selector(onClick)];
[buttonsetWidth:[UIApplicationsharedApplication].keyWindow.frame.size.width-50];
XMCustomKeyBoardBtn*button1=[[XMCustomKeyBoardBtnalloc]initWithTitle:@"隐藏键盘"style:UIBarButtonItemStyleBorderedtarget:targetaction:@selector(CancelableKeyboard:)];
button1.editableView=editableView;
[button1setWidth:50];
[toolbarsetItems:@[button,button1]];
returntoolbar;
}
-(void)CancelableKeyboard:(XMCustomKeyBoardBtn*)btn{
[btn.editableViewresignFirstResponder];
}
-(void)onClick{
}
@end
