當創建按鈕的網格時點擊和長按手勢Objective-C

晚上好，我試圖創建一個按鈕的網格，就像在下面的代碼中一樣。我想爲每個按鈕添加TapGesture和LongPress手勢;我該怎麼做？我知道這是一個辦法做到這一點......當創建按鈕的網格時點擊和長按手勢Objective-C

UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(longPress:)]; 
longPress.minimumPressDuration = 3; 
//[self.griglia[1][1] addGestureRecognizer:longPress];

如果我這樣做，它說：「財產‘griglia’不是類型的對象Gioco發現 Gioco.m/Gioco.h是我的課

和的UIButton * griglia [9] [9];是我的按鈕電網

你能糾正下面的代碼

 for(int i=0, y=212, p=0; i<9; i++) 
{ 

    for(int k=0, x=37; k<9; k++) 
    { 
     griglia[i][k] = [UIButton buttonWithType:(UIButtonTypeCustom)]; 

     //[griglia[i][k] addTarget:self action:(@selector(click)) forControlEvents: UIControlEventTouchDown]; 

     [griglia[i][k] setTag: 0]; 
     if(i==posizioni[0][p] && k==posizioni[1][p]) 
     { 
      numero=[NSString stringWithFormat:@"%d", matrice[i] [k]]; 
      [griglia[i][k] setTitle: numero forState: UIControlStateNormal]; 
      [griglia[i][k] setEnabled:NO]; //Numeri non modificabili 
      [griglia[i][k] setTag: matrice[i][k]]; 
     } 
     [griglia[i][k] setTitleColor:[UIColor blackColor] forState: UIControlStateNormal]; 
     griglia[i][k].frame=CGRectMake(x, y, 27, 27); 
     [self.view addSubview:griglia[i][k]]; 
     if(k==2 || k==5) 
      x=37+3+k*34; 

     else 
     x=37+k*34; 
    } 
    if(y==2 || y==5) 
     y=212+4+i*34; 

    else 
    y=212+i*34; 
}
