Question

我在A类中有UITableView，在B类中有自定义视图。我想要的是 - 从B类添加自定义视图到A类视图，然后删除该视图并显示表。

我确实添加了视图和逻辑来删除该视图，但出于某种原因，我的tableView单元格没有响应触摸。

以下是我创建和添加视图（B类）的方法：

-(id)initWithFrame:(CGRect)frame andRemoveTableView:(UITableView*)tableView{

    self = [super initWithFrame:frame];
    NSLog(@"Calld");
    self.backgroundColor = [UIColor whiteColor];
    [self addLabel];

     tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

    return self;
}

现在实施A类：

@implementation MainTableViewController{

    InitialView *initView;
    BOOL isInitialViewTapped;
}

-(void)viewDidLoad{

  //  InitialView *initView = [[InitialView alloc]initWithFrame:[[UIScreen mainScreen] bounds]];

//    self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];


    initView = [[InitialView alloc]initWithFrame:[[UIScreen mainScreen]bounds] andRemoveTableView:self.tableView];

    [self.view addSubview:initView];
   // [initView removeFromSuperview];

     //Notification Center

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(recieveTap:)
                                                 name:@"Tap"
                                               object:nil ];
    [self isViewTapped];

}

-(void)isViewTapped{


    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self  action:@selector(viewTapped:)];
    tap.numberOfTapsRequired = 1;
    [self.view addGestureRecognizer:tap];
}

-(void)viewTapped:(UIGestureRecognizer*)recognizer{

    [[NSNotificationCenter defaultCenter] postNotificationName:@"Tap" object:self];
    isInitialViewTapped = YES;
}

#pragma mark - table view delegate

-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    //Fill data
    InitialData *data = [InitialData new];
    data.isFirstCall = YES;

    //Show cell

    myCell *cell = [tableView dequeueReusableCellWithIdentifier:@"myCell" forIndexPath:indexPath];
    cell.taskText.text = [data.dataArray objectAtIndex:indexPath.row];
    cell.timeStartedText.text = [self dateStr];


    return cell;
}

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    return 1;

}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

    return 3;
}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

    NSLog(@"SELECT");
    [self performSegueWithIdentifier:@"push" sender:self];

}



#pragma mark - Notification Center

-(void)recieveTap:(NSNotification*)notification{

    if (!isInitialViewTapped){
    [initView  removeFromSuperview];

    if ([[notification name] isEqualToString:@"Tap"])

    }   else {
        [[NSNotificationCenter defaultCenter] removeObserver:self];
    }
}

非常简单。但是，当我点击屏幕并使我的自定义视图解除时，当我点击单元格segue不起作用。实际上，方法

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

    NSLog(@"SELECT");
    [self performSegueWithIdentifier:@"push" sender:self];

}

甚至不打印NSLog。如何解决？

UITableViewCell与UITapGestureRecognizer冲突。

您可以在调用 - （void）viewTapped：（UIGestureRecognizer *）识别器时删除手势。

如果你想保持手势，你应该设置手势代表。

-(void)isViewTapped{
    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self  action:@selector(viewTapped:)];
    tap.delegate = self; // add this line
    tap.numberOfTapsRequired = 1;
    [self.view addGestureRecognizer:tap];
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    // TableViewCell, do not handle it
    if ([NSStringFromClass([touch.view class]) isEqualToString:@"UITableViewCellContentView"]) {
        return NO;
    }
    return  YES;
}

UITableViewCell没有响应
