Parsing a Java Properties file in Objective-C for iPhone

Question

I\'m looking for a way in the iPhone SDK to read in a Properties file (not the XML flavor) for example this one:

# a comment
! a comment

a = a string
b = a          


        

Answer 1

I've ended with this solution if anybody is interested :

@interface NSDictionary (PropertiesFile)

+ (NSDictionary *)dictionaryWithPropertiesFile:(NSString *)file;

@end

@implementation NSDictionary (PropertiesFile)

+ (NSDictionary *)dictionaryWithPropertiesFile:(NSString *)file {
    NSError *error = nil;
    NSString *propertyFileContent = [[NSString alloc] initWithContentsOfFile:file encoding:NSUTF8StringEncoding error:&error];
    if (error) return nil;

    NSArray *properties = [propertyFileContent componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];
    if (properties.count == 0) return nil;

    NSMutableDictionary *result = [[NSMutableDictionary alloc] initWithCapacity:properties.count];
    for (NSString *propertySting in properties) {
        NSArray *property = [propertySting componentsSeparatedByString:@"="];

        if (property.count != 2) continue;

        [result setObject:property[1] forKey:property[0]];
    }
    return result.allKeys.count > 0 ? result : nil;
}

@end
