Cocoa contentsOfDirectoryAtPath：某些用户出现错误的方法 - Mac OS X

问题描述

下面是一段代码：

// Get into the data folder of it
keychainPath = [keychainPath stringByAppendingPathComponent:@"data/default"];

DLog(@"Keychain data path: %@", keychainPath);

// Define Filemanager
NSFileManager *fm = [NSFileManager defaultManager];

// Catch any errors
NSError *dataError = nil;

// get all the files in the directory
NSArray *dataFiles = [fm contentsOfDirectoryAtPath:keychainPath error:&dataError];

if(!dataFiles)
 NSLog(@"Error: %@",dataError);

现在这对大多数人来说都是完美的，但有几个人报告了问题，对象给：

Now this works perfectly fine for most people, but a few have reported problems, with the 'dataError' object giving:

  Error: Error
Domain=NSCocoaErrorDomain Code=260 UserInfo=0x14d1fa10 "The folder
"default" doesn’t exist." Underlying Error=(Error
Domain=NSOSStatusErrorDomain Code=-43 "The operation couldn’t be
completed. (OSStatus error -43.)" (File not found))

有这个问题的人说，文件/文件夹的默认存在于应该在哪里，所以我不知道为什么这不工作。

The people having this problem have said that the file / folder 'default' DOES exist exactly where is should be, so I have no idea why this isn't working.

任何帮助将不胜感激。

推荐答案

感谢Peter，keychainPath只是一些字符串，如'〜/ Library / etcet等。

Thanks Peter, the keychainPath was just some string like '~/Library/etc.etc.'

回答我自己的问题：

原来的问题是因为有些人的Mac OS X安装程序混淆了波浪号（〜）

It turns out the problem was because some people's Mac OS X installations were getting confused about the tilde (~)

使用方法

[keychainPath stringByExpandingTildeInPath];

一旦这样做，问题就解决了。

Once this was done, the problem was solved.

我猜这个问题的原因是有多个用户帐户的人，我没有。

I guess the reason for the problem was for people with multiple user accounts, which I didn't have.
