Question

Example:

NSData *fileData = [fileHandle readDataToEndOfFile];

Am I responsible for closing that file handle? (I think I’m not…but just 99.95% sure!)

Answer 1

You are not required to close the file handle, however, it is good practice to deallocate the NSFileHandle object when you are finished with it. This will ensure that the memory used by the application is kept to a minimum.

iOS Class Reference:

Note: The deallocation of an
NSFileHandle object deletes its
descriptor and closes the represented
file or channel unless the
NSFileHandle object was created with
initWithFileDescriptor: or
initWithFileDescriptor:closeOnDealloc:
with NO as the parameter argument.
