向 uitableview iPhone 的预定义数组添加一个值

Question

如何在

单击添加按钮的同时将新值添加到 uitableview 的预定义数组中？

-(IBAction)addNewBreed:(id)sender
{
    UIAlertView *addAlert=[[UIAlertView alloc]initWithTitle:@"Add New Item" message:@"nn" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Add",nil];
    UITextField *addTextField=[[UITextField alloc]initWithFrame:CGRectMake(12,45,260,25)];
    [addTextField becomeFirstResponder];
    [addTextField setBackgroundColor:[UIColor whiteColor]];
    addTextField.clearButtonMode=UITextFieldViewModeWhileEditing;
    [addAlert addSubview:addTextField];
    [addAlert show];

}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    NSString *buttonTitle=[alertView buttonTitleAtIndex:buttonIndex];
    if ([buttonTitle isEqualToString:@"Add"]) 
    {
         //HERE WHAT CODE SHOULD I ADD,MY ARRAY NAME 'ar'       
    }
    else
        return;
}

如果您的数组是 NSMutableArray ，则可以使用以下代码：

[ar addObject: addTextField.text];//you may also enter any string here
  [yourTableView reloadData];
