I try to fix issue but did not get solution. Please help me to fix the issue.

I am have created a custom view with a label to on table cellview, when we tap on that custom view , it show a UIMenuController with copy option. My custom view handle tap gesture as below

-(void) handleTapGesture:(UIGestureRecognizer*) recognizer{

    if (self.window == nil) {
        NSLog(@" \n\n\n\n Window is null \n\n\n\n\n\n");
        return;
    }

    [self becomeFirstResponder];

    CGRect targetRectangle = CGRectMake(self.bounds.size.width/2, 2, 2, 2);

    UIMenuController *menuController = [UIMenuController sharedMenuController];
    [menuController setTargetRect:targetRectangle inView:self];
    [menuController setMenuVisible:YES animated:YES];
} 

If I did not handle tap gesture and do not show this UIMenuController , then it does not produce any crashes.

Crashes occurs randomly , I have implement Pull to refresh in UITableView, on pull I download previous data from server and reload tableview, at the same time I tap on the custom view in cell, some time crashes occurs.

One more thing some time crashes occurs at handleTapGesture function as bellow.

Answer 1

Previously, I was getting the crash issue. As per my idea, since I was setting my custom view as first responder to show UIMenuController, that was required to visible UIMenuController. So I can't remove that statement.

To fix this, I resign to it as first responder just after the UIMenuController set as visible. Now my application does not get that random crashes.

-(void) handleTapGesture:(UIGestureRecognizer*) recognizer{

    if (self.window == nil) {
        NSLog(@" \n\n\n\n Window is null \n\n\n\n\n\n");
        return;
    }

    [self becomeFirstResponder];

    CGRect targetRectangle = CGRectMake(self.bounds.size.width/2, 2, 2, 2);

    UIMenuController *menuController = [UIMenuController sharedMenuController];
    [menuController setTargetRect:targetRectangle inView:self];
    [menuController setMenuVisible:YES animated:YES];

    [self resignFirstResponder];
}
