Inactive part of the screen on fullscreen - ios

Question

I'm trying to put a picture on fullscreen with buttons on to do actions.
Here is a screenshot of my result:
My problem is that the buttons on the first line (the highest) are not touchable.
It seems to have no action on the top layout.
Here is my code:
- (void)showActionsForGlobalFullScreen:(UIGestureRecognizer *)gestureRecognizer {
//LEFT
UIImage* cancelImage = [UIImage imageNamed:#"cancel.png"];
CGRect frameimg = CGRectMake(3, 3, cancelImage.size.width, cancelImage.size.height);
UIButton *cancelButton = [[UIButton alloc] initWithFrame:frameimg];
UIImage* flagImage = [UIImage imageNamed:#"flag.png"];
CGRect frameimg2 = CGRectMake(3, 40, flagImage.size.width, flagImage.size.height);
UIButton *flagButton = [[UIButton alloc] initWithFrame:frameimg2];
[cancelButton addTarget:self action:#selector(closeFullView:) forControlEvents:UIControlEventAllTouchEvents];
[cancelButton setBackgroundImage:cancelImage forState:UIControlStateNormal];
[flagButton addTarget:self action:#selector(displayFlag:) forControlEvents:UIControlEventAllTouchEvents];
[flagButton setBackgroundImage:flagImage forState:UIControlStateNormal];
//RIGHT
UIImage *exitFullScreenImage = [UIImage imageNamed:#"exitFullScreen.png"];
CGRect frameimg3 = CGRectMake(fullScreenViewFromVC.frame.size.width - 25 , 3, exitFullScreenImage.size.width, exitFullScreenImage.size.height);
UIButton *exitFullScreenButton = [[UIButton alloc] initWithFrame:frameimg3];
UIImage *commentImage = [UIImage imageNamed:#"comment.png"];
CGRect frameimg4 = CGRectMake(fullScreenViewFromVC.frame.size.width - 25 , 40, commentImage.size.width, commentImage.size.height);
UIButton *commentButton = [[UIButton alloc] initWithFrame:frameimg4];
[exitFullScreenButton addTarget:self action:#selector(exitFullScreenPhoto:) forControlEvents:UIControlEventAllTouchEvents];
[exitFullScreenButton setBackgroundImage:exitFullScreenImage forState:UIControlStateNormal];
[commentButton addTarget:self action:#selector(diplayComments:) forControlEvents:UIControlEventAllTouchEvents];
[commentButton setBackgroundImage:commentImage forState:UIControlStateNormal];
//[actionsView addSubview:flagButton];
[fullScreenViewFromVC addSubview:cancelButton];
[fullScreenViewFromVC addSubview:flagButton];
[fullScreenViewFromVC addSubview:exitFullScreenButton];
[fullScreenViewFromVC addSubview:commentButton];
}
Important note:
fullScreenViewFromVC is an own class extending UIView and instantiated on my controller.
Basically I'm called the fullscreen method from a picture on a UITableViewCell
I'm using this fullScreenViewFromVC variable to store my data from the current selected cell to my controller.
Thank you for your help.

Answer 1

Finally it was because of another view that I had to hide.
I thought that changing de zPosition of my view in fullscreen should be enough but it did not.
Problem solved.
