Objectiv C: Dateien nach Datum sortieren / sort files by date
Ein kleiner Codeschnipsel um Dateien in einem Array nach Datum zu sortieren:
NSString *documentsDirectory = @"XXX"; //path to the files NSArray *dirContents; dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:nil]; //save file-names to the array //sort function NSComparisonResult dateSort(NSString *f1, NSString *f2, void *context) { NSString *documentsDirectory = @"XXX"; //path to the files NSString *p1 = [NSString stringWithFormat:@"%@/%@", documentsDirectory, f1]; NSString *p2 = [NSString stringWithFormat:@"%@/%@", documentsDirectory, f2]; NSFileManager *fm2 = [[NSFileManager alloc] init]; return [[[fm2 fileAttributesAtPath:p2 traverseLink:YES] objectForKey:NSFileModificationDate] compare: [[fm2 fileAttributesAtPath:p1 traverseLink:YES] objectForKey:NSFileModificationDate]]; [fm2 release]; } dirContents = [dirContents sortedArrayUsingFunction:dateSort context:NULL];
