iOS自定义数字键盘
第一种方式： 在获得键盘弹出通知时，在键盘的那个 UIView 上添加一个自定义的 UIButto。
#define KEY_WIDTH 106
#define KEY_HEIGHT 53
#pragma mark – 处理 TextField 响应事件
– ( void )editingDidBegin:( UITextField *)textF {
[ self . textF becomeFirstResponder ];
}
//3. 实现通知处理
– ( void )handleKeyboardWillHide:( NSNotification *)notification
{
if ( doneInKeyboardButton . superview )
{
[ doneInKeyboardButton removeFromSuperview ];
}
}
– ( void )handleKeyboardDidShow:( NSNotification *)notification
{
NSDictionary *info = [notification userInfo ];
CGSize kbSize = [[info objectForKey : UIKeyboardFrameEndUserInfoKey ] CGRectValue ]. size ;
CGFloat normalKeyboardHeight = kbSize. height ;
int cnt = [[ UIApplication sharedApplication ] windows ]. count ;
UIWindow * tempWindow = [[[ UIApplication sharedApplication ] windows ] objectAtIndex :cnt- 1 ];
// create custom button
if ( doneInKeyboardButton == nil )
{
doneInKeyboardButton = [ UIButton buttonWithType : UIButtonTypeCustom ];
doneInKeyboardButton . frame = CGRectMake ( 18 , tempWindow. frame . size . height – 53 , 106 , 53 );
doneInKeyboardButton . adjustsImageWhenHighlighted = NO ;
[ doneInKeyboardButton setImage :[ UIImage imageNamed : @”done.png” ] forState : UIControlStateNormal ];
[ doneInKeyboardButton setImage :[ UIImage imageNamed : @”done.png” ] forState : UIControlStateHighlighted ];
[ doneInKeyboardButton addTarget : self action : @selector (finishAction) forControlEvents : UIControlEventTouchUpInside ];
}
// locate keyboard view
if ( doneInKeyboardButton . superview == nil )
{
// 注意这里直接加到 window 上
[tempWindow addSubview : doneInKeyboardButton ];
}
}
#pragma mark – 处理视图响应事件
– ( void )touchesBegan:( NSSet *)touches withEvent:( UIEvent *)event {
[ self . textF resignFirstResponder ];
}
-( void )viewWillAppear:( BOOL )animated
{
[ super viewWillAppear :animated];
//1. 先注册通知 [[ NSNotificationCenter defaultCenter ] addObserver : self selector : @selector (handleKeyboardDidShow:) name : UIKeyboardDidShowNotification object : nil ];
[[ NSNotificationCenter defaultCenter ] addObserver : self selector : @selector (handleKeyboardWillHide:) name : UIKeyboardWillHideNotification object : nil ];
}
//2. 在 dealloc 中反注册通知
-( void )dealloc
{
[[ NSNotificationCenter defaultCenter ] removeObserver : self ];
}
第二种方法：自己写一个键盘。:laughing:
