Question

I am testing NSMutableArray and do not understand what i am doing wrong.

When i define “myArray” locally the [myArray addObject:@”First line”]; works but if i define it in the .h file it ends up as null.

I am using myArray to add the text of multiple selected cell’s in a UITableView “didSelectRowAtIndexPath”.

Could someone nice explain what i am doing wrong?

Answer 1

Are you just declaring an NSMutableArray in the header file? If so, it still needs to be initialized somewhere in the .m file. You could do this like so:

array = [[NSMutableArray alloc] init];
[array addObject:@"First line"];
