UIButton not showing highlight on tap in iOS7

I've looked at a ton of posts on similar things, but none of them quite match or fix this issue. Since iOS 7, whenever I add a

to a
or even to the footerview it works "fine", meaning it receives the target action, but it doesn't show the little highlight that normally happens as you tap a
. It makes the UI look funky not showing the button react to touch.

I'm pretty sure this counts as a bug in iOS7, but has anyone found a solution or could help me find one :)

I forgot to mention that it will highlight if I long hold on the button, but not a quick tap like it does if just added to a standard view.


Creating the button:

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.titleLabel.font = [UIFont systemFontOfSize:14];
button.titleLabel.textColor = [UIColor blueColor];
[button setTitle:@"Testing" forState:UIControlStateNormal];
[button addTarget:self action:@selector(buttonPressed:) forControlEvents: UIControlEventTouchDown];
button.frame = CGRectMake(0, 0, self.view.frame.size.width/2, 40);

Things I've Tested:

//Removing gesture recognizers on
in case they were getting in the way.

for (UIGestureRecognizer *recognizer in self.tableView.gestureRecognizers) {
recognizer.enabled = NO;

//Removing gestures from the Cell

for (UIGestureRecognizer *recognizer in self.contentView.gestureRecognizers) {
recognizer.enabled = NO;

//This shows the little light touch, but this isn't the desired look

button.showsTouchWhenHighlighted = YES;


In that tableview you just add this property.

tableview.delaysContentTouches = NO;

And add in cellForRowAtIndexPath after you initiate the cell you just add below code. The structure of the cell is apparently different in iOS 6 and iOS 7.
iOS 7 we have one control UITableViewCellScrollView In between UITableViewCell and content View.

for (id obj in cell.subviews)
    if ([NSStringFromClass([obj class]) isEqualToString:@"UITableViewCellScrollView"])
        UIScrollView *scroll = (UIScrollView *) obj;
        scroll.delaysContentTouches = NO;
