專案開發很多時候用系統給的鍵盤不是很滿足自身實際需求，那就自定義一個吧：

方法其實很簡單，重新定義一個view，繼承UItextfield，把UI設計好的需求鍵盤加入新的otherKeyboardView，然後執行程式碼：

 self.inputView =self.otherKeyBoardView;

[selfreloadInputViews];

具體效果如下：

自己封裝了一個PassTextField類，直接呼叫就ok：

- (void)viewDidLoad {

[superviewDidLoad];

//自定義鍵盤呼叫

PassTextFild *searchTextField =[[

searchTextField.borderStyle =UITextBorderStyleRoundedRect;

searchTextField.placeholder =@"請輸入程式碼或拼音首字母";

searchTextField.font =[UIFontsystemFontOfSize:13];

searchTextField.contentVerticalAlignment =UIControlContentVerticalAlignmentCenter;

searchTextField.

searchTextField.returnKeyType = UIReturnKeyDone;

searchTextField.keyboardType =UIKeyboardTypeDefault;

searchTextField.clearButtonMode = UITextFieldViewModeAlways;

searchTextField.text =@"";

[self.viewaddSubview:searchTextField];

[searchTextField becomeFirstResponder

}

主要功能程式碼如下：

if (pressButtonCapital.selected)

{

addString =[addString uppercaseString];

}

NSMutableString* mutableString = [[NSMutableStringalloc] initWithFormat:@"%@%@",self.text, addString];

self.text = mutableString;

[selfsearchAllTextField];

//切換到123鍵盤

-(void)changeNumberKeyBoard

{

self.inputView =keyBoardView;

[selfreloadInputViews];

}

//空格

-(void)addNullAction

{

NSMutableString* mutableString = [[NSMutableStringalloc] initWithFormat:@"%@ ",self.text];

self.text = mutableString;

[selfsearchAllTextField];

}

//大小寫切換

-(void)pressCapitalAction:(UIButton *)button

{

if (button.selected){

button.selected =NO;

bacDaXieImage.image =[UIImageimageNamed:@"da_.png"];

}else{

button.selected =YES;

bacDaXieImage.image =[UIImageimageNamed:@"da.png"];

}

}
