Xcode:如何获取 textLabel 以显示在 textField 中输入的附加静态文本? [英] Xcode: How do I get a textLabel to display addition static text that is being entered in the textField?

问题描述

我是 Xcode 新手，请帮忙.

I am a Xcode newbie, please help.

所以我知道如何使用文本字段更改标签框中的文本:

So I know how to change the text in Label box by with a text field:

self.textLabel.text = self.textField.text

self.textLabel.text = self.textField.text

问题是:如何将静态文本添加到正在输入的文本中?

The question is: how do I add static text to text that is being entered?

就像在 textField 中输入名称一样，如何让标签框显示Hi"，然后输入任何文本?

Like if in the textField a name is entered, how do get the label box to display a "Hi," then whatever text that was entered?

在="符号之后的self.textField.text"前面需要放什么?

What do I have to put in front of "self.textField.text" after the "=" sign ?

谢谢

推荐答案

您需要连接 2 个字符串.这里有一些线索:

You need to concatenate 2 Strings. Here are some clues:

Objective-C 中连接 NSStrings 的快捷方式

在字符串 Objective-c 中连接字符串

Objective C 中的简单字符串连接

所以:

self.textLabel.text = [@"Hi" stringByAppendingString: self.textField.text]

或

[textLabel setStringValue: [@"Hi" stringByAppendingString: self.textField.text]];
