UIButton没有响应UITableViewCell中的单击事件

there is this dark sorcery in ios is preventing my button being clicked. if i don't add button to the uitableviewcell, and i click the button, the event is triggered. but if the button is in uitableviewcell, it won't get triggered, it seems table i have sample code ready, if you guys can help me, please just create a simple single-view application in xcode, and just paste the following code

ios中有一个黑魔法阻止我的按钮被点击。如果我不向uitableviewcell添加按钮，然后单击按钮，事件就会被触发。但是如果按钮在uitableviewcell中，它不会被触发，看起来表我已经准备好了示例代码，如果你们可以帮助我，请在xcode中创建一个简单的单视图应用程序，然后粘贴下面的代码

//GRDViewController.h

/ / GRDViewController.h

#import <UIKit/UIKit.h>

@interface GRDViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>

@property (nonatomic, strong) UIView* container;
@property (nonatomic, strong) UIButton* button;
@property (nonatomic, strong) UITableView* tableView;
@property (nonatomic, strong) NSArray* arr;

@end

//GRDViewController.m

/ / GRDViewController.m

#import "GRDViewController.h"

@implementation GRDViewController
@synthesize button, container, arr, tableView;

- (void)_btnTapped {
NSLog(@"TAPPED");
}

- (void)viewDidLoad 
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
    self.button = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];
    [self.button addTarget:self action:@selector(_btnTapped)    forControlEvents:UIControlEventTouchUpInside];
   [self.button setTitle:@"CLICK ME" forState:UIControlStateNormal];
  self.arr = [[NSArray alloc] initWithObjects:@"123", @"456", @"678", nil];

   self.container = [[UIView alloc]initWithFrame:self.button.frame];
  [self.container addSubview:self.button];
  [self.view addSubview:self.container];
  //[self.view  addSubview:self.button];

  self.tableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 100, 400, 400)];

 self.tableView.autoresizingMask = UIViewAutoresizingFlexibleHeight |   UIViewAutoresizingFlexibleWidth;
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
  self.tableView.delegate = self;
  self.tableView.dataSource = self;

  [self.view addSubview:self.tableView];

self.tableView.backgroundColor  = [UIColor redColor];





}



   - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:  (NSIndexPath *)indexPath {
static NSString *cellIdentifier = @"coolcell";
UITableViewCell *cell = [tableView    dequeueReusableCellWithIdentifier:cellIdentifier];

  if (cell == nil) {
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault   reuseIdentifier:cellIdentifier];
      //cell.accessoryType = UITableViewCellAccessoryNone;

      UIButton * btn =  [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 50, 50)];
         [btn addTarget:self action:@selector(_btnTapped)   forControlEvents:UIControlStateNormal];
      [btn setTitle:[self.arr objectAtIndex:[indexPath row]]     forState:UIControlStateNormal];
     [cell.contentView addSubview:btn];
         }

    return cell; 
}
- (NSInteger)tableView:(UITableView*)tableView numberOfRowsInSection:(NSInteger)section {
   return [self.arr count];      
}
 @end

please help i feel this case should be common in ios, but nobody has solution for this???

请帮助我觉得这个案例在ios里应该是普遍的，但是没有人有解决的办法???

edit: when click on the button it prints NSLOG msg in the xcode console...so make sure...u r looking at the results there...

编辑:当点击按钮时，它会在xcode控制台打印NSLOG msg…所以要确保……你正在看那里的结果……

3 个解决方案

#1

you have not given any control event to button .Change it to UIControlEventTouchUpInside from UIControlStateNormal

你没有给任何控件事件的按钮。改变它从UIControlEventTouchUpInside从uicontrolstat诺曼

#2

Instead of using UIControlStateNormal for ControlEvents use UIControlEventTouchUpInside like this

使用uicontroleventtouchupin而不是UIControlStateNormal，像这样

[btn addTarget:self action:@selector(_btnTapped) forControlEvents:UIControlEventTouchUpInside];

#3

Try doing this:

试着这样做:

[btn.titleLabel setUserInteractionEnabled: NO];

[btn。titleLabel setUserInteractionEnabled:没有);
