拡張可能なテーブルビューを上下に移動しているときにエラーが発生します。 これは、キャッチされない例外により 'NSRangeException' にアプリを終了*理由私のエラー です: '* - [__ NSSingleObjectArrayI objectAtIndex:]:範囲外のインデックス3 [0 .. 0]'拡張可能なテーブルビューを移動中にエラーが発生しましたか?
arr = [[NSArray alloc]initWithObjects:@"obj1",@"obj2",@"obj3",@"obj4",nil];
arr1 = [[NSArray alloc]initWithObjects:@"Name1", @"name2", @"name3", @"name4", @"name5", @"name6", nil];
arr2 = [[NSArray alloc]initWithObjects:@"arr2obj", nil];
arr3 = [[NSArray alloc]initWithObjects:@"arr3obj", nil];
arr4 = [[NSArray alloc]initWithObjects:@"arr4obj", nil];
これがされ私のコード...

- (IBAction)dropDownButton:(UIButton *)送信者メソッドの使用方法は何ですか? –
これは、セルの配列を動的に割り当てる.... – iOS
呼び出されるのはいつですか? –
