如何将NSMutableArray复制到另一个NSMutableArray

Question

If i have 2 NSMutableArray declared in .h, synthesize in .m files, how can i copy whole contents of array 1 to 2? actually the same array.

I tried using this code only:

[self.data addObjectsFromArray:self.temparray]

to copy data from temparray to data.

doesn't seems to work.....

Answer 1

Did you initialize your self.data at all? Ie self.data = [NSMutableArray array]; somewhere.

If you did, please post some code.

Answer 2

- (NSArray *)arrayByAddingObjectsFromArray:(NSArray *)otherArray

是您要寻找的方法。
