在按鈕上單擊輸入附件視圖

Question

我在視圖中有兩個文本字段和一個按鈕。在按鈕單擊中，我希望鍵盤顯示並獲取PIN碼。 我想創建一個如下所示的視圖。

我試過，但不能得到這樣的事情。我怎麼能做出這樣的事情？

Answer 1

你應該使用這樣的事情：

- (IBAction)clickButton 
{ 
    [yourTextField becomeFirstResponder]; 
} 

Answer 2

這個代碼是不是tested.but你可以做這樣的

- (IBAction)clickButton 
{ 
    [self createInputAccessoryView]; 
    [yourTextField becomeFirstResponder]; 
} 

-(void)createInputAccessoryView{ 

    UIToolbar *keyboardToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 44)]; 
    CGRect rect=CGRectMake(0, 0, 25, 25); 

    UITextField *txtFeild1=[[UITextField alloc]initWithFrame:rect]; 
    UITextField *txtFeild2=[[UITextField alloc]initWithFrame:rect]; 
    UITextField *txtFeild3=[[UITextField alloc]initWithFrame:rect]; 
    UITextField *txtFeild4=[[UITextField alloc]initWithFrame:rect]; 

    [keyboardToolbar addSubview:txtFeild1]; 
    [keyboardToolbar addSubview:txtFeild2]; 
    [keyboardToolbar addSubview:txtFeild3]; 
    [keyboardToolbar addSubview:txtFeild4]; 

    [txtFeild1 setInputAccessoryView:keyboardToolbar]; 
    [txtFeild2 setInputAccessoryView:keyboardToolbar]; 
    [txtFeild3 setInputAccessoryView:keyboardToolbar]; 
    [txtFeild4 setInputAccessoryView:keyboardToolbar]; 

}
