Hi List, I with to filter array using NSPredicate (seems a lot more easier than while loop with NSEnumerator), after read through some cocoa examples online, I run a simple test using the following codes:
NSArray *pitches = [NSArray arrayWithObjects: @"Do", @"Re", @"Mi", @"Fa", @"So", @"La", nil]; NSArray *filteredWithSELF = [pitches filteredArrayUsingPredicate: [NSPredicate predicateWithFormat: @"SELF == 'Do'"]]; NSArray *filteredWithDescription = [pitches filteredArrayUsingPredicate: [NSPredicate predicateWithFormat: @"description == 'Do'"]]; NSArray *filteredWithFormat = [pitches filteredArrayUsingPredicate: [NSPredicate predicateWithFormat: @"SELF == '%@'", @"Do"]]; Out of the three predicate statements, however, the first and last one return me empty array. Only the second one returns an array containing 1 element which is the @"Do" string. Did I make any mistake in the codes, or this feature is not fully implemented yet in base-1.20? Thanks and Regards, Nyap-Hong
