自定义UITableViewCell的accessoryView 判断哪个Button按下

UITableview的开发中经常要自定义Cell右侧的AccessoryView，把他换成带图片的按钮，并在用户Tap时判断出是哪个自定义按钮被按下了。

创建自定义按钮，并设为AccessoryView

if (cell == nil) { 

    cell = [[UITableView alloc] initWithStyle:UITableViewCellStyleDefault                                  reuseIdentifier:identifier]; 

    UIImage *image= [ UIImage imageNamed:@"delete.png" ];

    UIButton *button = [ UIButton buttonWithType:UIButtonTypeCustom ];

    CGRect frame = CGRectMake( 0.0 , 0.0 , image.size.width , image.size.height );

    button. frame = frame;

    [button setBackgroundImage:image forState:UIControlStateNormal ];

    button. backgroundColor = [UIColor clearColor ];

    [button addTarget:self action:@selector(buttonPressedAction  forControlEvents:UIControlEventTouchUpInside]; 

    cell. accessoryView = button;

 } 

如果将Button加入到cell.contentView中，也是可以的。

cell.contentView addSubview:button];

在Tap时进行判断，得到用户Tap的Cell的IndexPath

- (void)buttonPressedAction  id)sender 

{ 

   UIButton *button = (UIButton *)sender; 

   (UITableViewCell*)cell = [button superview]; 

   int row = [myTable indexPathForCell:cell].row; 

} 

对于加到contentview里的Button， 

(UITableViewCell*)cell = [[button superview] superview];
