I'm having difficulty to add a data structure to an array to create an array of dictionaries from a loop. I just knew that addObject in NSMutableArray only add pointer to it. I would like to know how to achieve my goal.
Here's my code:
NSMutableDictionary *woRows = [[NSMutableDictionary alloc] init];
NSMutableArray *workOrders = [[NSMutableArray alloc] init];
while ([theScanner isAtEnd] == NO)
{
if ([theScanner scanUpToCharactersFromSet:usSet intoString:&tempCol1] &&
[theScanner scanString:@"{US}" intoString:NULL] &&
[theScanner scanUpToCharactersFromSet:usSet intoString:&tempCol2] &&
[theScanner scanString:@"{US}" intoString:NULL] &&
[theScanner scanUpToCharactersFromSet:usSet intoString:&tempCol3]&&
[theScanner scanString:@"{RS}" intoString:NULL])
{
[woRows setValue:tempCol1 forKey:@"hours"];
[woRows setValue:tempCol2 forKey:@"colMain"];
[woRows setValue:tempCol3 forKey:@"colAddtl"];
[workOrders addObject:woRows];
[woRows release];
}
}
[tmpString release];
[jobs addObject:workOrders];
[workOrders release];
from the code above, the array workOrders will have duplicates of last objects added only. I stuck here not able to progress to display the correct data.
Any help will be appreciated.
Thanks
try doing [workOrders addObject:[woRows copy]];
