这是我如何保存文本的代码

NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [documentPaths objectAtIndex:0];
    NSString *documentTXTPath = [documentsDirectory stringByAppendingPathComponent:@"myFile.plist"];
    NSString *savedString = _textView.text;
    //NSString *saveString=_textView2.text;
    [savedString writeToFile:documentTXTPath atomically:YES ];

请告诉我如何检索它。请帮我。以及如何在我的项目本身中制作plist。谢谢。

This is code how I save text

NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [documentPaths objectAtIndex:0];
    NSString *documentTXTPath = [documentsDirectory stringByAppendingPathComponent:@"myFile.plist"];
    NSString *savedString = _textView.text;
    //NSString *saveString=_textView2.text;
    [savedString writeToFile:documentTXTPath atomically:YES ];

Please tell me how to retrieve it. Please help me. And how to make plist in my project itself.
Thank you.

快速的方法是：

NSString *myText = [NSString stringWithContentsOfFile:filePath
                            encoding: NSUTF8StringEncoding
                            error: NULL];

不要忘记进行错误处理。

请注意，这将阻塞主线程，直到加载整个文本文件。如果您正在处理大文件，您可能需要使用 mmap 和 munmap。

顺便说一句，如果您想通过网络加载文本文件，永远不要使用NSString stringWithContentsOfURL（或任何一般的 *WithContentsOfURL 方法）。此方法将阻塞主线程，直到文件下载完毕。在这种情况下，请改用 NSURLConnection 或 ASIHTTPRequest。

The quick way would be:

NSString *myText = [NSString stringWithContentsOfFile:filePath
                            encoding: NSUTF8StringEncoding
                            error: NULL];

Don't forget to do your error handling.

Be aware that this will block the main thread until the whole text file has been loaded. If you're dealing with large files, you may want to use mmap and munmap.

As a side note, if you'll ever want to load a text file over a network, never use NSString stringWithContentsOfURL (or any of the *WithContentsOfURL methods in general). This method will block the main thread until the file has been downloaded. In that case, use NSURLConnection or ASIHTTPRequest instead.

您可以尝试使用 NSString 类方法 stringWithContentsOfFile:
