我需要公开因为我正在使用GroceryCRUD并使用回调 - 将其设置为受保护意味着GroceryCRUD不会使用其回调来调用它.
所以看起来它必须是公开的.我如何声明它是公开的,但确保CodeIgniter不会从URL请求中调用它(即,如果我去http://site.com/images/process_images/test.jp它不会调用它::process_images('test.jpg'))

label.alpha = 0.0f;
// or
label.hidden = YES;

但是,在两种情况下,标签都会占用空间(其宽度和高度)。
是否可以隐藏标签以使其不占用任何垂直/水平空间?一种可能的方法是将宽度/高度设置为0。但是也许有更好的方法。
我要求用户输入一个数字,我要在其中打印列表中该索引点处的项目.
这是我目前的代码:

new_item = raw_input("Which item would you like to add? ")
List.append(new_item)
print "The list has the following", len(List), "items:", List
Number = raw_input ("Please select a number: ")
