NSURL fileURLWithPath example ios

fileURLWithPath:

Initializes and returns a newly created NSURL object as a file URL with a specified path.

+ (id)fileURLWithPath:(NSString *)path

Parameters

path

The path that the NSURL object will represent. path should be a valid system path. If pathbegins with a tilde, it must first be expanded with stringByExpandingTildeInPath. If pathis a relative path, it is treated as being relative to the current working directory.

Passing nil for this parameter produces an exception.

Return Value of [NSURL fileURLWithPath]

An NSURL object initialized with path.

Discussion of [NSURL fileURLWithPath]

This method assumes that path is a directory if it ends with a slash. If path does not end with a slash, the method examines the file system to determine if path is a file or a directory. If pathexists in the file system and is a directory, the method appends a trailing slash. If path does not exist in the file system, the method assumes that it represents a file and does not append a trailing slash.

As an alternative, consider using fileURLWithPath :isDirectory:, which allows you to explicitly specify whether the returned NSURL object represents a file or directory.
