getting the value of key in dictionary incorrectly

what having far right is

code:

    nsarray *keys = [nsarray arraywithobjects:@"firstname",@"lastname",@"phonenumber",@"email",@"password",nil];        nsarray *objects = [nsarray arraywithobjects:@"nil",@"nil",@"nil",@"nil",@"abc",nil];        dictionary = [nsdictionary dictionarywithobject:objects forkey:keys];        nslog(@"pass %@",[keys objectatindex:4]);        nslog(@"value of pass is%@",[dictionary objectforkey:@"password"]);

however, got debugger is

code:

    pass password        value of pass (null)

can explain why value null.it should abc,shouldn't it.

 

i think want dictionarywithobjects rather dictionarywithobject, here code (for me) works:

code:

nsarray *keys = [nsarray arraywithobjects:@"firstname",@"lastname",@"phonenumber",@"email",@"password",nil];          nsarray *objects = [nsarray arraywithobjects:@"nil",@"nil",@"nil",@"nil",@"abc",nil];          nsdictionary *dictionary = [[nsdictionary alloc] init];          dictionary = [nsdictionary dictionarywithobjects:objects forkeys:keys];          nslog(@"pass %@",[keys objectatindex:4]);          nslog(@"value of pass is%@",[dictionary objectforkey:@"password"]);

note have initialised array in version can test it, can remove line.
