RandomKeyboard

实现iOS随机数字键盘，主要用以交易密码之类的管理。 防止键盘记录器记录到。

使用方法

UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(100, 100, 100, 44)];
textField.backgroundColor = [UIColor lightGrayColor];
textField.delegate = self;

XTYRandomKeyboard *keyBoad = [[XTYRandomKeyboard alloc] initWithTitleColor:[UIColor blackColor] backGroundImage:[UIImage imageNamed:@"bg.jpg"]];
[keyBoad setInputView:textField];
[self.view addSubview:textField];

如果想每次点击都随机键盘
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
/*不建议每次点击都随机键盘，随机键盘只是为了避免键盘监控的，同一输入点每次都随机，会给用户造成学习成本*/
XTYRandomKeyboard *keyBoad = [[XTYRandomKeyboard alloc] initWithTitleColor:[UIColor blackColor] backGroundImage:[UIImage imageNamed:@"bg.jpg"]];
[keyBoad setInputView:textField];
return YES;
}
