我有一个自定义单元格，它使用具有以下组件的情节提要：

1 UIImage 2 UILabels 4 UIbuttons

一个按钮允许用户将优惠券保存为收藏夹，我想在用户保存优惠券后将此按钮设置为禁用，我尝试为自定义单元格类中的按钮添加 IBOutlet 但它不起作用而且我没有得到任何错误。我怎样才能做到这一点？有人可以帮助我吗？

编码：

优惠券Cell.h

@property (nonatomic, strong) IBOutlet UIButton *saveFav;

优惠券Cell.m

#import "CouponsCell.h"

@implementation CouponsCell
@synthesize saveFav;

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Initialization code
    }
    return self;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}
@end

我已经在 IBOutlet 和按钮之间建立了连接，当用户触摸按钮时，我尝试了这个：

- (IBAction)AddFavorite:(id)sender {

    CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.tableView];
    NSIndexPath * indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];
    Coupons * couponsObjects = [self.fetchedResultsController objectAtIndexPath:indexPath];

    CouponsCell *couponsCell = [self.tableView dequeueReusableCellWithIdentifier:@"CouponCell" forIndexPath:indexPath];

    idCoupon = cuponesObjects.idCoupons;

    Reachability *reachability = [Reachability reachabilityForInternetConnection];
    [reachability startNotifier];
    NetworkStatus status = [reachability currentReachabilityStatus];

    if ( status == NotReachable )
    {
        UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"CC Galerias"
                                                          message:@"Can’t save the Coupon to favorite, Check your Internet connection."
                                                         delegate:nil
                                                cancelButtonTitle:@"OK"
                                                otherButtonTitles:nil];

        [message performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:YES];
    }
    else if ( status == ReachableViaWiFi )
    {
        [self postCouponFav:idCoupon]; // Save the Coupon to Favorites
        [couponsCell.saveFav setEnabled:NO]; // Set diseable the button


    }
    else if ( status == ReachableViaWWAN )
    {
        [self postCouponFav:idCoupon];
        [couponsCell.saveFav setEnabled:NO];

    }

}

请帮助我，也许解决方案很简单，但我正在学习 iOS 开发。提前感谢您对我的帮助。

您不能使用 dequeue，因为返回单元格是单元格的新实例，而不是显示的单元格。

您有两种更改按钮状态的方法。

  • Transport your (IBACTION)method in your custom cell class and not in controller class and release legacy code. If you need to update data between CustomCell and controller create and invoke a delegate.

  • The second way is to reload the Cell of UITableView after setting necessary values for presented the well state
