UITableViewCell IBAction在iOS 7中不起作用

Question

What I'm facing is I've developed code in Swift. It has a some custom cells and UIButtons in them. The buttons are IBOutlet Connections with properties in their respective Cells and actions against them are bound in the same classes. Now the Question is that it works perfect in iOS 8. But I don't know what's wrong with iOS 7 whenever I touch the button, the complete cell is tapped and Tableview's didSelectRowAtIndexPath: is called. What I've done so far is

• Check .userInteractionEabled for parent views and cell and changing it's values
• Remove buttons and re add them as found on different forums but no luck
• Checked Tableview's delegate methods numberOfSections , numberOfRowsInsection: and heightForRowAtIndexPath: and changed their return types to NSInteger and CGFloat as found on stackoverflow Against a Question.

Has anyone else faced this issue and found solution so far?

Edit

• Checked by reseting target action of UIButton after setting values to cell. No Luck

I have tested your problem. Its running fine for me. Please see my code below.

In TestTableViewController.swift

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCellWithIdentifier("reuseIdentifier", forIndexPath: indexPath) as CustomCell

       // Configure the cell...

        cell.testButton.addTarget(cell, action: "testButtonClicked", forControlEvents: UIControlEvents.TouchUpInside)

       return cell

    }

       override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

        NSLog("didSelectRowAtIndexPath called")

    }

In CustomCell.swift

class CustomCell: UITableViewCell {

    @IBOutlet var testButton: UIButton!

    override func awakeFromNib() {

        super.awakeFromNib()

        // Initialization code

    }

    override func setSelected(selected: Bool, animated: Bool) {

        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state

    }

    func testButtonClicked() {

        NSLog("Button Clicked")

    }

}

When I clicked on the button it logs "Button Clicked" and when clicked on cell it logs "didSelectRowAtIndexPath called". You might be doing something wrong in reset() function or second last function.

I have done the code below in my app and it is working fine.

Do not try to code on your custom tableview cell.

You can get values of that cell in your viewcontroller.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (indexPath.row==0)
    {
        static NSString *simpleprice = @"Price";

        price = (PriceCell *)[tableView dequeueReusableCellWithIdentifier:simpleprice];

        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"PriceCell" owner:self options:nil];

        price = [nib objectAtIndex:0];
        [price.btnPrice addTarget:self action:@selector(buyPressed) forControlEvents:UIControlEventTouchUpInside];
    }
    return price;

 }

Hope this helps you. This works for ios7 and ios8 also.

Thanks...

i have faced such issue after long time digging it, i found root cause and it was in Cell XIB

what i did as Before:

i) First i have added CustomCell .h and .m .
ii) After then i have added XIB by new file option, you have noticed, there is option like "View" that's i have selected and add in to the bundle. Bind it with my CustomCell.h .

Solution :

i) Add XIB by new file option, Choose View in user interface. ii) In XIB you can see view at left panel. delete that view. iii) Drag and drop there UITableViewCell from User Interface panel. After complete this steps XIB would be seen similar something like below image.

将您的cell.button Action target to self更改Action target to self ，然后将您的按钮操作方法复制到UITableView可用的viewController类（.mm）文件中。
