[NSString stringByResolvingSymlinksInPath]
Returns a new string made from the receiver by resolving all symbolic links and standardizing path.
- (NSString *)stringByResolvingSymlinksInPath
Return Value of [NSString stringByResolvingSymlinksInPath]
A new string made by expanding an initial tilde expression in the receiver, then resolving all symbolic links and references to current or parent directories if possible, to generate a standardized path. If the original path is absolute, all symbolic links are guaranteed to be removed; if it’s a relative path, symbolic links that can’t be resolved are left unresolved in the returned string. Returns
self if an error occurs.Discussion of [NSString stringByResolvingSymlinksInPath]
If the name of the receiving path begins with
/private, the stringByResolvingSymlinksInPath method strips off the /private designator, provided the result is the name of an existing file.
Note that this method only works with file paths (not, for example, string representations of URLs).
Example of [NSString stringByResolvingSymlinksInPath]
void checkForCapsIssues(NSString* compiledPath)
{
NSArray* validFilePaths = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:[[compiledPath stringByDeletingLastPathComponent] stringByResolvingSymlinksInPath] error:nil];
NSString* lastPathComponent = [compiledPath lastPathComponent];
for (NSString* fileName in validFilePaths) {
if([fileName isEqualToString:lastPathComponent])
{
return;
}
if([[fileName lowercaseString] isEqualToString:[lastPathComponent lowercaseString]])
{
NSLog(@"Warning! Caps Problem Found! %@", compiledPath);
return;
}
}
}
