Ios 在表视图目标c中的按钮上添加操作

我必须为此添加警报按钮。我希望按钮上的操作能够尽快完成。我已经编写了此代码以打开警报

        cell.btnCommentOption.tag = indexPath.row;
        if([Boomerang sharedManager].currentUser.user_id != comment.user.user_id){
            cell.btnCommentOption.hidden = YES;
            [cell.btnCommentOption addTarget:self action:@selector(didTapButton:) forControlEvents:UIControlEventTouchUpInside];
        }

按钮的动作是

- (IBAction)btnCommentOptionsTapped:(UIButton*)sender {
    UIAlertController * alert = [UIAlertController
                                 alertControllerWithTitle:@"Share"
                                 message:@""
                                 preferredStyle:UIAlertControllerStyleActionSheet];



    UIAlertAction* sharefeed = [UIAlertAction
                                actionWithTitle:@"Share feed"
                                style:UIAlertActionStyleDefault
                                handler:^(UIAlertAction * action) {
                                    [alert dismissViewControllerAnimated:YES completion:^{}];
                                }];

    UIAlertAction* report = [UIAlertAction
                             actionWithTitle:@"Report"
                             style:UIAlertActionStyleDefault
                             handler:^(UIAlertAction * action) {
                                  [alert dismissViewControllerAnimated:YES completion:^{}];
                             }];

    UIAlertAction* cancel = [UIAlertAction
                             actionWithTitle:@"Cancel"
                             style:UIAlertActionStyleDefault
                             handler:^(UIAlertAction * action) {
                                 [alert dismissViewControllerAnimated:YES completion:^{}];
                             }];

    [alert addAction:sharefeed];
    [alert addAction:report];
    [alert addAction:cancel];

    [self presentViewController:alert animated:YES completion:nil]
}

当我将操作添加到按钮时，出现错误，请帮助我解决此错误是

不可见@interface for UIImageView declears选择器addTarget:action:forcontrolEvents

检查您的操作名称是否正确

[cell.btnCommentOption addTarget:self action:@selector(didTapButton:) forControlEvents:UIControlEventTouchUpInside];

或

更新答案

if([Boomerang sharedManager].currentUser.user_id == comment.user.user_id){
        cell.btnCommentOption.hidden = NO;
        [cell.btnCommentOption addTarget:self action:@selector(didTapButton:) forControlEvents:UIControlEventTouchUpInside];
    }else
     {
      cell.btnCommentOption.hidden = YES;
     }

并将您的按钮操作称为

- (IBAction)didTapButton:(UIButton*)sender {

不是

最后一次上升

“UIImageView没有不可见的@界面可清除选择器addTarget:action:forcontrolEvents”

错误显示

cell.btncommentonoption是UIimageview而不是UIButton

UIImageView

不是一个

UIControl

，因此它没有

addTarget:action:forControlEvents

方法作为其界面的一部分。您可以改用手势识别器

在

cellforrowatinexpath

方法中添加此代码

cell. btnCommentOption.userInteractionEnabled = YES;
cell. btnCommentOption.tag = indexPath.row;
 cell.btnCommentOption.hidden = YES;
 if([Boomerang sharedManager].currentUser.user_id == comment.user.user_id){
        cell.btnCommentOption.hidden = NO;
        UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(btnCommentOptionsTapped:)];
tap.numberOfTapsRequired = 1;
[cell.btnCommentOption addGestureRecognizer:tap];

    } 

并将该方法称为

- (void)btnCommentOptionsTapped:(UITapGestureRecognizer *)sender {

“UIImageView没有不可见的@界面可清除选择器addTarget:action:forcontrolEvents”

---

发生此错误是因为addTarget方法是按钮的，并且您正试图在UIImageView上调用它。请检查自定义单元格中的出口参考。附加到

btnCommentOption

的参考不是按钮，而是UIImageView。

错误是什么这一个是正确的

cell.btnCommentOption.hidden=YES

或此项正确

cell.btnCommentOption.hidden=NO如果您在条件内部调用更新，请仔细查看我已从条件外部调用了操作，但存在相同的问题您是否可以显示与此相关的addtarget
btncommentonoptions点击
这不是一个问题我已经做了很多次，并且在我的最后一个问题中出现了相同的错误您是否添加了
addTarget:action:forcontrolEvents
对于您的图像视图，如果是，请将
addTarget:action:forcontrolEvents
更改为点击手势，@HusnainAli-cell.btn提示选项是UIimageview或UIButton
cell. btnCommentOption.userInteractionEnabled = YES;
cell. btnCommentOption.tag = indexPath.row;
 cell.btnCommentOption.hidden = YES;
 if([Boomerang sharedManager].currentUser.user_id == comment.user.user_id){
        cell.btnCommentOption.hidden = NO;
        UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(btnCommentOptionsTapped:)];
tap.numberOfTapsRequired = 1;
[cell.btnCommentOption addGestureRecognizer:tap];

    } 

- (void)btnCommentOptionsTapped:(UITapGestureRecognizer *)sender {
