Question

I want to collect all searchString from UISearchBar when the user clicked the button “x” to a mutable array, but however it is being added no object to self.historyList….

In the method:

            - (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchString
        {
            self.ss = searchBar.text;

//this is initialized in viewDidLoad method
            //self.addSSFort = [[NSMutableArray alloc]init];

            [self.addSSFort addObject: self.ss];

            NSLog (@"addSSFort contains %@", self.addSSFort);

            //NSMutableArray *historyList = [[[NSMutableArray alloc]init]retain];
//this one is initialized in viewDidLoad method
            //self.historyList = [[NSMutableArray alloc]init];

            if ([self.ss length] == 0)
            {
        // here it is never being added
                [self.historyList addObject:[self.addSSFort objectAtIndex:[self.addSSFort count]-1]];
            }
    }

EDIT :

self.addSSFort contains:

x
xc
xco
xcod
xcode <- I want to add this to self.historyList
""
t
tr
tre
tree <- I want to add this to self.historyList
""

But self.historyList contains:

""
""

I want it to contain:

xcode
tree

I use this statement if ([self.ss length] == 0), because it tells me that the user has clicked on “x” to erase searchString and tells me s/he is finished with the current searchString.
I know about ARC, but I am doing this for the users who have iOS 3 > iOS 5.

EDIT 2:

Ah, I have solved this!

Answer 1

It should be:

[self.historyList addObject:[self.addSSFort objectAtIndex:[self.addSSFort count]-2]];

instead of:

[self.historyList addObject:[self.addSSFort objectAtIndex:[self.addSSFort count]-1]];
