UIBUtton Action in UICollectionReusableView

Question

我在UICollectionReusableView中添加UIButton。我可以添加按钮及其操作，但按钮操作不起作用。我已经尝试通过添加TapGesture并启用UICollectionReusableView和按钮的用户交互，但没有效果。 下面是我的代码

- (instancetype)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
self.userInteractionEnabled = YES;
self.backgroundColor = [UIColor menigaLightBackgroundColor];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:self.frame];
imageView.userInteractionEnabled = YES;
imageView.image = [UIImage imageNamed:@"Login_115"];
imageView.contentMode = UIViewContentModeScaleAspectFill;
imageView.tag = 10;
[self addSubview:imageView];
UIImage *titleImage  = [UIImage imageNamed:@"titleLogo"];
UIImageView *imageViewTitle = [[UIImageView alloc] initWithFrame:CGRectMake(0.0, 0.0, titleImage.size.width, titleImage.size.height)];
imageViewTitle.userInteractionEnabled = YES;
imageViewTitle.center = self.center;
imageViewTitle.contentMode = UIViewContentModeScaleAspectFit;
imageViewTitle.image = titleImage;
[self addSubview:imageViewTitle];
float margin = 15.0;
//Title Label  //10 is the tag for Arch image view
titleLabel = [[UILabel alloc]initWithFrame:CGRectMake(margin, CGRectGetMaxY([self viewWithTag:10].frame)+ 10 , CGRectGetWidth(self.frame)-margin*2, 60.0)];
titleLabel.text = @"Your wallets have been linked successfully. Link more accounts now to fully understand your spending.";
titleLabel.numberOfLines = 4;
titleLabel.userInteractionEnabled = YES;
titleLabel.textAlignment = NSTextAlignmentCenter;
titleLabel.font = [UIFont getDINRegularFontOfSize:16];
titleLabel.textColor = [UIColor menigaDarkTextColor];
[self addSubview:titleLabel];
//Buttons
linkAccountButton = [[CustomButtonClass alloc] initWithFrame:CGRectMake(margin,  CGRectGetMaxY(titleLabel.frame)+ 10, CGRectGetWidth(self.frame)-margin*2, 44.0)];
linkAccountButton.userInteractionEnabled = YES;
linkAccountButton.layer.cornerRadius = 22.0;
[linkAccountButton setTitle:@"Link An Account" forState:UIControlStateNormal];
[linkAccountButton.titleLabel setFont:[UIFont getRobotFontOfSize:14]];
[linkAccountButton setBackgroundColor:[UIColor menigaBrandColorRed]];
[self addSubview:linkAccountButton];
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(linkButtonPressed)];
tapGesture.numberOfTapsRequired = 1;
[linkAccountButton addGestureRecognizer:tapGesture];
[linkAccountButton buttonTouchUpInsideWithCompletion:^{
MENIGAChooseOrganizationVC *vc = [[MENIGAChooseOrganizationVC alloc] init];
vc.signupFlow = YES;
[_parent.navigationController pushViewController:vc animated:YES];
}];
//set button hidden
titleLabel.hidden = YES;
linkAccountButton.hidden = YES;
}
return self;
}

下面是点击手势

//MARK:- Link button Action
-(void)linkButtonPressed
{
OrganizationVC *vc = [[OrganizationVC alloc] init];
vc.signupFlow = YES;
[_parent.navigationController pushViewController:vc animated:YES];
}

请帮助我做错了什么。

在UIButtons上使用内部修饰而不是手势识别器

[linkAccountButton addTarget:self action:@selector(linkButtonPressed:) forControlEvents:UIControlEventTouchUpInside];

然后操作应该是：

-(void) linkButtonPressed:(UIButton*)sender
