アニメーションが動作しないUIImageView（ストーン 'オブジェクト'）の位置を更新します。

Question

5x5グリッドの周りに「石」画像をスワイプする動きをコーディングしようとしています。 つまり、私の石の1つが列3、行1で始まり、下にスワイプすると、列3、行4（NSInteger配列[5] [5]）に終わるはずです。 私のような、@implementation {}でアウトレットビューのインスタンス変数を持っている：

：

IBOutlet UIView* _one; 

ここで私は、ビュー上で「_one」を下にスワイプここ

- (void)swipeDown:(UISwipeGestureRecognizer *)recognizer { 
     NSLog(@"Swipe Down"); 
     UIView *view = recognizer.view; 
     if (view == _one) { 
      _currentCol = stoneOneColumn; 
      _currentRow = stoneOneRow; 
      _state = (BoardCellState)BoardCellStateStoneOne; 
      NSLog(@"Got it 3"); 
     } else if (view == _two) { // code for '_two' } 
     [self move:CGPointMake(0, 1) withView:view]; 
    } 

    - (void)move:(CGPoint)direction withView:(UIView*)stoneView { 
     NSLog(@"Got it 5"); 
     CGFloat oldCol = _currentCol; 
     CGFloat oldRow = _currentRow; 
     while ([self indexValid:_currentCol y:_currentRow]) { 
      NSLog(@"Got it 5.5"); 
      CGFloat newCol = _currentCol + direction.x; 
      CGFloat newRow = _currentRow + direction.y; 
      if ([self indexValid:newCol y:newRow]) { 
       NSLog(@"Got it 5.75"); 
       _currentCol = newCol; 
       _currentRow = newRow; 
      } else { 
       NSLog(@"Got it close to 6"); 
       _currentCol = newCol; 
       _currentRow = newRow; 
       break; 
      } 
     } 
     NSLog(@"Got it 6"); 
     [_board setCellState:BoardCellStateEmpty forColumn:oldCol 
                andRow:oldRow]; 
     [_board setCellState:_state forColumn:_currentCol 
             andRow:_currentRow]; 
     NSLog(@"Got it 7"); 
     [UIView animateWithDuration:0.8 
           delay:1.0 
          options:UIViewAnimationOptionCurveLinear 
          animations:^{ 
          CGRect rect = stoneView.frame; 
          rect.origin.x = 
           _frame.origin.x + (_currentCol*61.5); 
          rect.origin.y = 
           _frame.origin.y + (_currentRow*61.5); 
          } 
          completion:^(BOOL finished) { 
          NSLog(@"Done finally"); 
          }]; 
    } 

    - (BOOL)indexValid:(NSInteger)x y:(NSInteger)y { 
     NSLog(@"Got it 8"); 
     BOOL indexValid = TRUE; 
     if ((x < 0) || (x > 4) || (y < 0) || (y > 4)) { 
      NSLog(@"Got it 10"); 
      indexValid = FALSE; 
      return indexValid; 
     } else 
      return indexValid; 
    }

は何が起こっているのかについて、いくつかのコメントである：

1. BoardCellState is an enum (...StoneOne or ...StoneTwo) signifies the 
     state of the stone (is the view I'm animating one or two). 
    2. The while loop runs through the numerical positions, using the 
     indexValid method to break it when either col or row positions exceed 
     the _board[5][5] 'boundary'. 
    3. There are setter and getter methods in another file for stone positions. 
     I set the Empty state to the old column and row, and set the current 
     state to the new column and row. 
    4. THEN I perform the animation! But the problem is, the stone on my 
     iPhone (when I test it, that is) doesn't move at all, even though 
     the output goes through this entire process. That's where I'm stuck. 

問題の内容を確認できません。それは 'アニメーション：'ブロック内のコードですか？ 'move：withView：'メソッドの戻り値を変更する必要がありますか？ アニメーションメソッドの[UIView ...]は、私がアニメーション化したいものが、プロセス全体で正常に渡された 'stoneView'であることを理解していますか？この -Anthony

を見て取るための

おかげで私はあなたがstoneView.frame

animations:^{ 
CGRect rect = stoneView.frame; 
rect.origin.x = 
_frame.origin.x + (_currentCol*61.5); 
rect.origin.y = 
_frame.origin.y + (_currentRow*61.5); 

へ rectを再割り当てするのを忘れたと思います

stoneView.frame = RECT。
