objective c - Problem retrieving data from array iphone? -

i declared nsmutablearray , assign object when retrieving object gives memory location.here code.

nsmutablearray *arrcondinum = [[nsmutablearray alloc] init]; [arrcondinum addobject:@"2"]; [arrcondinum addobject:@"4"]; [arrcondinum addobject:@"6"]; [arrcondinum addobject:@"8"]; for(int = 0;i<[arrcondinum count];i++){     nslog(@"array number %d",[arrcondinum objectatindex:i]); } 

output gives
array number 20820
array number 20836
array number 20852
array number 20868

you add string in array, display it, have use %@:

nslog(@"array number %@",[arrcondinum objectatindex:i]); 

in code (%d), display address of object.

%@ display description of objc object (return of -descriptionwithlocale: or -description)
