NSURL initFileURLWithPath example ios


Initializes a newly created NSURL referencing the local file or directory at path.
- (id)initFileURLWithPath:(NSString *)path
Parameters of [NSURL initFileURLWithPath]
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
An NSURL object initialized with path.
Discussion of [NSURL initFileURLWithPath]
Invoking this method is equivalent to invoking initWithScheme:host:path: with schemeNSURLFileScheme, a nil host, and path.
This method examines path in the file system to determine if it is a directory. If path is a directory, then a trailing slash is appended. If the file does not exist, it is assumed that pathrepresents a directory and a trailing slash is appended. As an alternative, consider using initFileURLWithPath :isDirectory: which allows you to explicitly specify whether the returned NSURL represents a file or directory.
Example of [NSURL initFileURLWithPath]
NSString* targetFilePath = @"/Users/bob/Documents/About_Stacks.pdf";
NSURL* targetFileURL = [[NSURL alloc] initFileURLWithPath:targetFilePath];
