在UITextView中显示没有\\\<br/>的段落 [英] Display Paragraphs in UITextView without \n

问题描述

有一个方便的方式来格式化一个相当长的字符串与其中的段落（如下），使它与 \\\
，因此textView将显示段落？

  blah 
 
 blah 
  

到 @blah\\\
\\\
blah

解决方案

下面是一个简单的例子假设你有：

• 一个名为的文件：myfile.txt


• 用于保存文件内容的字符串变量，我们将其命名为：content


• 一个UITextView调用：textView

在你的文本文件中写任何你想要的东西，从Xcode下的Ressources中导入它），然后在代码中的某个地方（init方法或动作）：

  NSString * path = [[NSBundle mainBundle] pathForResource：@myfile
 ofType：@txt]; 
 NSString * content = [NSString stringWithContentsOfFile：path 
 encoding：NSUTF8StringEncoding 
 error：NULL]; 
 
 textView.text = content; 
  

Is there a convenient way to format a rather long string with paragraphs in it (like below) to have it with \n in it so the textView will display the paragraphs as well?

blah

blah

to @"blah\n\nblah"

Thanks!

解决方案

Here's a simple example assuming you have :

• A file named : myfile.txt
• A string variable to hold the file's content, let's name it : content
• A UITextView called :textView

Write whatever you want in your text file and place it wherever you want in your Xcode project (usually import it from within Xcode under "Ressources"), and then somewhere in your code (init method or action) :

NSString *path = [[NSBundle mainBundle] pathForResource:@"myfile" 
                                                 ofType:@"txt"];
NSString *content = [NSString stringWithContentsOfFile:path 
                                              encoding:NSUTF8StringEncoding 
                                                 error:NULL];

textView.text = content;
