NSString completePathIntoString caseSensitive matchesIntoArray filterTypes example ios


completePathIntoString: caseSensitive: matchesIntoArray: filterTypes:

Interprets the receiver as a path in the file system and attempts to perform filename completion, returning a numeric value that indicates whether a match was possible, and by reference the longest path that matches the receiver.
- (NSUInteger)completePathIntoString:(NSString **)outputName caseSensitive:(BOOL)flag matchesIntoArray:(NSArray **)outputArray filterTypes:(NSArray *)filterTypes
Parameters
outputName
Upon return, contains the longest path that matches the receiver.
flag
If YES, the methods considers case for possible completions.
outputArray
Upon return, contains all matching filenames.
filterTypes
An array of NSString objects specifying path extensions to consider for completion. only paths whose extensions (not including the extension separator) match one of those strings.
Return Value of [NSString completePathIntoString caseSensitive matchesIntoArray filterTypes ]
0 if no matches are found and 1 if exactly one match is found. In the case of multiple matches, returns the actual number of matching paths if outputArray is provided, or simply a positive value if outputArray is NULL.
Discussion of [NSString completePathIntoString caseSensitive matchesIntoArray filterTypes ]
You can check for the existence of matches without retrieving by passing NULL as outputArray.
Note that this method only works with file paths (not, for example, string representations of URLs).
