Question

我有一个带按钮的costoum单元格。我希望能够在按下按钮时更改按钮的图像。我正在尝试这个，但我没有得到理想的结果。

in cellForRowAtIndexPath：

BOOL isTheObjectThere = [self.favoriteArry containsObject:self.tableData[indexPath.row]];
        if (isTheObjectThere==TRUE) {
            cell.favBtn.hidden = NO;
           [cell.favBtn setImage:[UIImage imageNamed:@"fav_selected.png"] forState:UIControlStateNormal];
            cell.favBtn.tag = indexPath.row;
            [cell.favBtn addTarget:self action:@selector(favoriteBtn:) forControlEvents:UIControlEventTouchUpInside];}
else {
            cell.favBtn.hidden = NO;
            [cell.favBtn setImage:[UIImage imageNamed:@"Favourites_Green@3x.png"] forState:UIControlStateNormal];
            cell.favBtn.tag = indexPath.row;
            [cell.favBtn addTarget:self action:@selector(unfavoriteBtn:) forControlEvents:UIControlEventTouchUpInside];  
        }

和：

-(void)favoriteBtn:(UIButton*)sender
{
        if ([cell.favBtn.currentImage isEqual:[UIImage imageNamed:@"fav_selected.png"]]){
        [cell.favBtn setImage:[UIImage imageNamed:@"Favourites_Green@3x.png"] forState:UIControlStateNormal];
}

    else  if ([cell.favBtn.currentImage isEqual:[UIImage imageNamed:@"Favourites_Green@3x.png"]]){
        [cell.favBtn setImage:[UIImage imageNamed:@"fav_selected.png"] forState:UIControlStateNormal];

    }

应该类似于以下内容：

cellForRow ：

中的

[cell.favButton addTarget:self action:@selector(favButtonTapped:) forControlEvents:UIControlEventTouchUpInside];

favButtonTapped ：

中的

if ([self.favoriteArray containsObject:indexPath]) {
    [self.favoriteArray removeObject:indexPath];
    // sender setImage...
} else {
    [self.favoriteArray addObject:indexPath];
    // sender setImage...
}

祝你好运：）
