【问题描述】：

我有问题

我创建了 6 个 UIButtons 将它们放入 UIView1

然后将UIView1 放入另一个UIView2

然后将UIView2作为UITableView.tableHeaderView返回

现在问题是当我触摸按钮时

不负责任

这里有一些信息 1. UIButtons UIView1 UIView2 fremes 是这些

2.我打开UIButtonsUIView1UIView2的userInteractionEnabled，你可以在代码中看到：

    #import "TableViewDataSource.h"


@implementation TableViewDataSource

@synthesize tableView;
@synthesize tableCell;
@synthesize LHfetchedResultsController;
@synthesize numberOfRows;
@synthesize dataTemp;
@synthesize paused;
@synthesize type;

-(id)initWithTableView:(UITableView *) tableView

    self = [super init];
    if (self) 
        self.tableView = tableView;
        self.tableView.dataSource = self;
        self.tableView.delegate = self;
        self.tableView.tableHeaderView = [self setHeaderView];
    
    return self;

-(UIView *)setHeaderView

    CGSize screenSize = [UIScreen mainScreen].bounds.size;
    UIView * container = [[UIView alloc] init];
    container.frame = CGRectMake(0, 0, screenSize.width, 20);
    container.userInteractionEnabled = YES;

    UIView * headerView = [[UIView alloc] init];
    headerView.frame = CGRectMake(0, 0, screenSize.width*1.5, 20);
    headerView.tag = 01;
    headerView.userInteractionEnabled = YES;
    [container addSubview:headerView];
    for (int i = 1; i < 7; i++) 
        UIButton * button = [[UIButton alloc] init];
        button.tag = i+10;
        button.titleLabel.font = [UIFont boldSystemFontOfSize:12];
        [button setTitle:[NSString stringWithFormat:@"but0%d",i] forState:UIControlStateNormal];
        [button setTitle:[NSString stringWithFormat:@"but0%d s",i] forState:UIControlStateSelected];
        [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        button.translatesAutoresizingMaskIntoConstraints = NO;
        [button setTitleColor:[UIColor brownColor] forState:UIControlStateSelected];
        button.enabled = YES;
        button.userInteractionEnabled = YES;
        [headerView addSubview:button];
    
    UIButton *button01 = [headerView viewWithTag:11];
    UIButton *button02 = [headerView viewWithTag:12];
    UIButton *button03 = [headerView viewWithTag:13];
    UIButton *button04 = [headerView viewWithTag:14];
    UIButton *button05 = [headerView viewWithTag:15];
    UIButton *button06 = [headerView viewWithTag:16];

    NSDictionary * views = NSDictionaryOfVariableBindings(button01,button02,button03,button04,button05,button06);
    NSString * vflV1 = @"V:|-1-[button01]-1-|";

    NSString * vflH1 = @"H:|-[button01]-[button02(==button01)]-[button03(==button01)]-[button04(==button01)]-[button05(==button01)]-[button06(==button01)]-|";

    NSArray * constraintsV1 = [NSLayoutConstraint constraintsWithVisualFormat:vflV1 options:0 metrics:NULL views:views];
    NSArray * constraintsV2 = [NSLayoutConstraint constraintsWithVisualFormat:vflV2 options:0 metrics:NULL views:views];

    NSArray * constraintsH1 = [NSLayoutConstraint constraintsWithVisualFormat:vflH1 options:0 metrics:NULL views:views];

    [headerView addConstraints:constraintsV1];
    [headerView addConstraints:constraintsV2];
    [headerView addConstraints:constraintsV3];
    [headerView addConstraints:constraintsV4];
    [headerView addConstraints:constraintsV5];
    [headerView addConstraints:constraintsV6];
    [headerView addConstraints:constraintsH1];

    return container;

我还没找到原因

谁能帮帮我？

我还在UIView2中添加了一些UISwipeGestureRecognizer

谢谢你

【问题讨论】：

可能有一个view覆盖了你的tableview的header部分，检查一下。

我的结构是这样的：self.tableView.tableHeaderView包含一个UIView，然后UIView包含6个UIButtons，关于这些的所有代码都在那里，我可以在代码中成功获取按钮，所以我不确定是否还有其他我没有注意到的观点，你能告诉我它可能是什么观点吗？

是否有一个视图包含tableView？该容器视图中还有其他视图吗？

如果你这样做NOT 将UISwipeGestureRecognizer 添加到UIView2 你可以点击按钮吗？如果是这样，那么你已经找到了问题。

@YunCHEN 我没有在容器视图中添加另一个UIView，并且tableView 是插入主ViewController，我可以触摸UITableViewCell

【参考方案1】：

谢谢你们 我得到了解决方案 原因是 [button addTarget:NULL action:@selector(click:) forControlEvents:UIControlEventTouchUpInside]; 我将目标设置为NULL，并在同一个文件中写入click:，但实际上我是从主控制器获取表格，所以当我点击按钮时，xcode会在主控制器中找到click:，然后找不到，所以没有责任。 在我设置目标自我或在主控制器中写入click: 它有效
