Title Body

EDIT_v002 I have had a look at all the comments and I am starting to see what I should be doing. To that end I have modified my code (see below) I have changed newPath to a NSString, removed the [[alloc] init] and the end [release] as its now handled by the system. I am using stringByAppendingPathComponent, letting it add a separator between rootPath and fileName before its assigned to the NSString. It does work, and I ran it through the static analyser with no problems. // ------------------------------------------------------------------- ** // DISC: FILEWALKER ..... (cocoa_fileWalker.m) // DESC: List all "*.png" files in specified directory // ------------------------------------------------------------------- ** #import <Foundation/Foundation.h> int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; NSString *fileName; NSDictionary *attrDir; NSError *myError; NSNumber *fileSize; NSFileManager *manager = [NSFileManager defaultManager]; NSString *rootPath = [@"~/Pictures/Ren/PRMan" stringByExpandingTildeInPath]; NSString *newPath; NSLog(@"Home: %@",rootPath); for(fileName in [manager enumeratorAtPath:rootPath]){ if ([[fileName pathExtension] isEqual:@"png"]) { newPath = [rootPath stringByAppendingPathComponent:fileName]; attrDir = [manager attributesOfItemAtPath:newPath error:&myError]; fileSize = [attrDir objectForKey: @"NSFileSize"]; NSLog(@"File: %@ Size: %@", newPath, fileSize); } } [pool drain]; return 0; } // ------------------------------------------------------------------- ** gary
