UiTextField rightView 代替clearButton 自定义clearButtton

一、创建View rightView位置偏右  不是很美观   所以先创建view 在view上 添加图片

 UIView *rightVeiw = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 30, 20)];

二、创建clearButton图片

UIImageView* xImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"btn_x.png"];]

xImageView.frame = CGRectMake(10, 0,14,14);

    [rightVeiw addSubview:xImageView];

三、创建TextField rightView

self.textField.rightView = rightVeiw;

    self.textField.rightViewMode = UITextFieldViewModeWhileEditing;

四、为图片xImageView 添加点击事件 清除文本框的内容

 xImageView.userInteractionEnabled = YES;

    UITapGestureRecognizer *xImageViewTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(xImageViewClick:)];

    [xImageView addGestureRecognizer:xImageViewTap];

点击事件 ：

- (void)xImageViewClick:(UITextField*) textField

{

    if(self.textField.editing)

    {

        [self.textField setText:@""];

    }

}

;
