將值添加到預定義的數組爲uitableview iphone

Question

如何添加一個新值到預定義數組的uitableview，同時單擊添加按鈕？

-(IBAction)addNewBreed:(id)sender 
{ 
    UIAlertView *addAlert=[[UIAlertView alloc]initWithTitle:@"Add New Item" message:@"\n\n" 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; 
} 

Answer 1

如果陣列是NSMutableArray，那麼你可以使用下面的代碼：

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