unrecognized selector sent to class 0x51e8'

I have this error, when I am trying to pass a uitextfeild value from my tableView:didSelectRowAtIndexPath: method in my uitableview over to my nsobject class however when I click the uitableviewcell that I have coded to pass the uitextfield value I receive the error listed below.

//DBAccess.h

    @interface DBAccess : NSObject {

        NSString *receiveCodeText;

    }

    @property (nonatomic, retain) IBOutlet NSString *receiveCodeText;

- (NSMutableArray *) getAllMakes;
    - (void) setPassCode:(NSString *)theCode;

//DBAccess.m

//...
//Need to set my string here..
- (void)setPassCode:(NSString *)theCode{
    receiveCodeText = theCode;
}
//...
- (NSMutableArray *)getAllMakes{
//...
const char *value = [receiveCodeText cStringUsingEncoding:NSUTF8StringEncoding]; //reciveCodeText is set in RootViewController and passed to value here
    [receiveCodeText release];
    sqlite3_bind_text(statement, 1, value, -1, SQLITE_TRANSIENT);

//....
}

//viewController.m

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    searchTableViewController *searchTable = [[searchTab开发者_开发百科leViewController alloc] initWithNibName:@"searchTableViewController" bundle:nil];

    switch (indexPath.row) {
        case 1: {
            searchTable.editedFieldName = @"Make";
            //Pass code number over to DBAccess class
            [DBAccess setPassCode:codeText.text];
        } break;
        case 2: {
            searchTable.editedFieldName = @"Mod";
        } break;
        case 3: {
            searchTable.editedFieldName = @"Method";
        } break;
    }

    [self.navigationController pushViewController:searchTable animated:YES];
    [searchTable release];
}

And this is the error I am getting.

setPassCode seems to be a class instance method and not a static method, yet you are trying to access it as a static method, you must declare yur method like so in order for it to be static

+(void)setPassCode....

Your program crashes because you are calling the method on the class itself instead of on an instance of the class.. Hope this helps
