-(IBAction)Done :(id) sender {

    NSMutableArray *addinfo = [[NSMutableArray alloc]init]; 

    AddinfoCarteV *addinfoCarteV =[[AddinfoCarteV alloc]initWithNibName:@"AddinfoCarteV" bundle:nil]; 
    [addinfo addObject:textfieldToAdd.text]; 
    NSLog(@"%@",addinfo); 
    addinfoCarteV.informationMan = addinfo ; 
    textfieldToAdd.hidden= NO ; 
}

Answer 1

Please try to ask questions clearly..I think you need to allocate and initialize your addinfoCarteV.informationMan array.or if you want to copy your addinfo array to informationMan array try this code

addinfoCarteV.informationMan = [[NSMutableArray alloc] init];

[addinfoCarteV.informationMan addObjectsFromArray:addinfo];
