好的我用一些技巧做了;）首先制作了一个UITextField并增加了它大小如下：

Ok I did it with some trick ;) First made a UITextField and increased it's size like this :

CGRect frameRect = textField.frame
frameRect.size.height = 53
textField.frame = frameRect

然后我在与我制作UITextField相同的区域制作了一个UITextView，删除了它的背景颜色。现在看起来我有多行TextField！

Then I made a UITextView exactly in the same area that i made my UITextField, and deleted its background color. Now it looks like that I have a multiple lines TextField !
