Button inside table cell not clickable

问题

I have a custom cell which has two buttons that are connected to it's methods. I add the cell to the table like this:

BSOrderedItemCell *cell = (BSOrderedItemCell *)[tableView dequeueReusableCellWithIdentifier:@"OrderItemCell"];
if (cell == nil) {
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"OrderItemCell" owner:self options:nil];
    cell = (BSOrderedItemCell *)[nib objectAtIndex:0];
}

And after that I set it's properties.

The cell size is the same as table's heightForRowAtIndexPath: and none of the cells labels or buttons are outside that size.

The problem is that I can select the cell, but I can't tap on the buttons. It's as if I'm tapping on a label, nothing happens. So I end up with something like this:

EDIT: Just to clarify things. The problem is not the button click methods. It's that I can't physically click the button, like there is something in the way of it, or it's disabled by some control.

回答1:

you need to do following things

1. Set the tag of your button in yourcellxib. orderitemcell in your case

2. get the button

   UIButton *btn =(UIButton*)[cell viewWithTag:]; btn.tag=indexPath.row;

3.add method to your button

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

now make a method

-(void)buttonClicked:(UIButton*)btn
{
NSLog(@"the button clicked is on cell number%d",btn.tag);

}

回答2:

You can try this..

[cell.button addTarget:self action:@selector(buttonClicked:)  forControlEvents:UIControlEventTouchUpInside];

To avoid cell selection:

Cell's xib -> Selection -> Set as None

回答3:

Do not create IBOutlot for then in you cellForRowAtIndexpath add the method to button

[cell.button addTarget:self action:@selector(buttonClicked:)  forControlEvents:UIControlEventTouchUpInside];

and perform the selector there and if you do not required row did select delegate then add

cell.userInteractionEnabled = NO; //too
