I won't pretend to be an expert on the topic, but you should have access to both the <code>glob</code> and <code>wordexp</code> function from objective-c, no?

blocks|key|1637125|text|使用NSString的hasSuffix和hasPrefix方法怎么样？类似于(如果你在搜索"foo*.jpg")：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1637126|NSString+*bundleRoot+=+[[NSBundle+mainBundle]+bundlePath];
NSArray+*dirContents+=+[[NSFileManager+defaultManager]+directoryContentsAtPath:bundleRoot];

++++if+([tString+hasPrefix:@"foo"]+&&+[tString+hasSuffix:@".jpg"])+{

++++++++//+do+stuff

++++}
}|code-block|syntax|javascript|1637127|对于像这样简单、直接的匹配，它将比使用regex库更简单。|1637128|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

What about using NSString's hasSuffix and hasPrefix methods? Something like (if you're searching for "foo*.jpg"):

<pre><code>NSString *bundleRoot = [[NSBundle mainBundle] bundlePath];
NSArray *dirContents = [[NSFileManager defaultManager] directoryContentsAtPath:bundleRoot];
for (NSString *tString in dirContents) {
 if ([tString hasPrefix:@"foo"] &amp;&amp; [tString hasSuffix:@".jpg"]) {

 // do stuff

 }
}
</code></pre>

For simple, straightforward matches like that it would be simpler than using a regex library.

blocks|key|1422268|text|在NSPredicate的帮助下，您可以很容易地实现这一点，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1422269|NSString+*bundleRoot+=+[[NSBundle+mainBundle]+bundlePath];
NSFileManager+*fm+=+[NSFileManager+defaultManager];
NSArray+*dirContents+=+[fm+contentsOfDirectoryAtPath:bundleRoot+error:nil];

NSArray+*onlyJPGs+=+[dirContents+filteredArrayUsingPredicate:fltr];|code-block|syntax|javascript|1422270|如果你需要使用NSURL来做这件事，它看起来像这样：|1422271|NSURL+*bundleRoot+=+[[NSBundle+mainBundle]+bundleURL];

++++++++includingPropertiesForKeys:@[]+

You can achieve this pretty easily with the help of NSPredicate, like so:

<pre><code>NSString *bundleRoot = [[NSBundle mainBundle] bundlePath];
NSFileManager *fm = [NSFileManager defaultManager];
NSArray *dirContents = [fm contentsOfDirectoryAtPath:bundleRoot error:nil];
NSPredicate *fltr = [NSPredicate predicateWithFormat:@"self ENDSWITH '.jpg'"];
NSArray *onlyJPGs = [dirContents filteredArrayUsingPredicate:fltr];
</code></pre>

If you need to do it with NSURL instead it looks like this:

<pre><code>NSURL *bundleRoot = [[NSBundle mainBundle] bundleURL];
NSArray * dirContents = 
 [fm contentsOfDirectoryAtURL:bundleRoot
 includingPropertiesForKeys:@[] 
 options:NSDirectoryEnumerationSkipsHiddenFiles
 error:nil];
NSPredicate * fltr = [NSPredicate predicateWithFormat:@"pathExtension='jpg'"];
NSArray * onlyJPGs = [dirContents filteredArrayUsingPredicate:fltr];
</code></pre>

blocks|key|1422320|text|在iOS中，stringWithFileSystemRepresentation似乎不可用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1422321|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

stringWithFileSystemRepresentation doesn't appear to be available in iOS.

blocks|key|1637272|text|这在IOS上工作得很好，但也应该在cocoa上工作。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1637273|NSString+*bundleRoot+=+[[NSBundle+mainBundle]+bundlePath];

This works quite nicely for <code>IOS</code>, but should also work for <code>cocoa</code>.

<pre><code>NSString *bundleRoot = [[NSBundle mainBundle] bundlePath];
NSFileManager *manager = [NSFileManager defaultManager];
NSDirectoryEnumerator *direnum = [manager enumeratorAtPath:bundleRoot];
NSString *filename;

while ((filename = [direnum nextObject] )) {

 //change the suffix to what you are looking for
 if ([filename hasSuffix:@".data"]) { 

 // Do work here
 NSLog(@"Files in resource folder: %@", filename); 
 } 
}
</code></pre>

Very Simplest Method:

NSString *documentsDirectory = [paths objectAtIndex:0];

NSFileManager *manager = [NSFileManager defaultManager];
NSArray *fileList = [manager contentsOfDirectoryAtPath:documentsDirectory 
 error:nil];
//--- Listing file by name sort
NSLog(@"\n File list %@",fileList);

//---- Sorting files by extension 
NSArray *filePathsArray = 
 [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory 
 error:nil];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF EndsWith '.png'"];
filePathsArray = [filePathsArray filteredArrayUsingPredicate:predicate];
NSLog(@"\n\n Sorted files by extension %@",filePathsArray);

For some crazy reason I can't find a way to get a list of files with a glob for a given directory.

I'm currently stuck with something along the lines of:

<pre><code>NSString *bundleRoot = [[NSBundle mainBundle] bundlePath];
NSArray *dirContents = [[NSFileManager defaultManager] 
 directoryContentsAtPath:bundleRoot];
</code></pre>

..and then stripping out the stuff I don't want, which sucks. But what I'd really like is to be able to search for something like "foo*.jpg" instead of asking for the entire directory, but I've not been able to find anything like that.

So how the heck do you do it?
