Question

How can I append one NSMutableArray to another, from what I’ve seen, it sound be fairly straight forward. But I’m getting some weird results, I think the amount of items in my temp array are being added but the dictionary values are being lost.

This is my current code, where I just overwrite my self.transactionArray

h - file
NSMutableArray *transactionArray;
@property (nonatomic, retain) NSMutableArray *transactionArray;

m - file
NSMutableArray *arrayTmp= [[NSMutableArray alloc] init];

//start loop
[arrayTmp addObject:[NSDictionary dictionaryWithObjectsAndKeys:desc,@"desc",
         due,@"due",nil]];  
//release nsstring desc etc
//end loop

self.transactionArray = arrayTmp;

[arrayTmp release];

My second attempt…

NSMutableArray *array1 = [arrayTmp mutableCopy];
[self.transactionArray addObjectFromArray:array1];

This was my first attempt…

[self.transactionArray addObjectFromArray:arrayTmp];

What am I doing wrong ?

You can do that like this:

[self.transactionArray addObjectsFromArray:arrayTmp];

And on a side note, please always read the documentation before posting a question. This method is easily found in the NSMutableArray documentation.
