UIMenuController method setTargetRect:inView: not working in UITableView - ios

Question

I am displaying custom UIMenuController in my tableview like this
but issue is that it is displaying in the center I want to display it on top of label which is orange colored. For displaying on top of label I did this [menu setTargetRect:CGRectMake(10, 10, 0, 0) inView:self.lbl]; below is the entire code.
But if I am displaying the UIMenuController without UITableView setTargetRect works fine.
Why setTargetRect is not working with UITableView?
setTargetRect Doc says:
(a) This target rectangle (targetRect) is usually the bounding rectangle
of a selection. UIMenuController positions the editing menu above this
rectangle; if there is not enough space for the menu there, it
positions it below the rectangle. The menu’s pointer is placed at the
center of the top or bottom of the target rectangle as appropriate.
(b) Note that if you make the width or height of the target rectangle
zero, UIMenuController treats the target area as a line or point for
positioning (for example, an insertion caret or a single point).
(c) Once it is set, the target rectangle does not track the view; if the
view moves (such as would happen in a scroll view), you must update
the target rectangle accordingly.
What I am missing?
MyViewController
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 5;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
TheCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cid" forIndexPath:indexPath];
cell.lbl.text = [NSString stringWithFormat:#"%ld", (long)indexPath.row];
return cell;
}
- (BOOL)tableView:(UITableView *)tableView shouldShowMenuForRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}
-(BOOL)tableView:(UITableView *)tableView canPerformAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender {
return YES;
}
- (void)tableView:(UITableView *)tableView performAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender {
// required
}
MyCustomCell
- (void)awakeFromNib {
// Initialization code
UIMenuItem *testMenuItem = [[UIMenuItem alloc] initWithTitle:#"Test" action:#selector(test:)];
UIMenuController *menu = [UIMenuController sharedMenuController];
[menu setMenuItems: #[testMenuItem]];
[menu setTargetRect:CGRectMake(10, 10, 0, 0) inView:self.lbl];
[menu update];
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
-(BOOL) canPerformAction:(SEL)action withSender:(id)sender {
return (action == #selector(copy:) || action == #selector(test:));
}
/// this methods will be called for the cell menu items
-(void) test: (id) sender {
NSLog(#"test");
}
-(void) copy:(id)sender {
UIMenuController *m = sender;
NSLog(#"copy");
}

Answer 1

1) First, please do this in your view controller's viewDidLoad method.
UIMenuItem *testMenuItem = [[UIMenuItem alloc] initWithTitle:#"Test"
action:#selector(test:)];
[[UIMenuController sharedMenuController] setMenuItems: #[testMenuItem]];
[[UIMenuController sharedMenuController] update];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(menuControllerWillShow:) name:UIMenuControllerWillShowMenuNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(menuControllerWillHide:) name:UIMenuControllerWillHideMenuNotification object:nil];
2) Then, add these two Methods. and set menuFrame inView to your cell
-(void)menuControllerWillShow:(NSNotification *)notification{
//Remove Will Show Notification to prevent
// "menuControllerWillShow" function to be called multiple times
[[NSNotificationCenter defaultCenter]removeObserver:self name:UIMenuControllerWillShowMenuNotification object:nil];
//Hide the Original Menu View
UIMenuController* menuController = [UIMenuController sharedMenuController];
CGSize size = menuController.menuFrame.size;
CGRect menuFrame;
menuFrame.origin.x = self.tableView.frame.origin.x;
menuFrame.size = size;
[menuController setMenuVisible:NO animated:NO];
//Modify its target rect and show it again to prevent glitchy appearance
[menuController setTargetRect:menuFrame inView:cell];
[menuController setMenuVisible:YES animated:YES];
}
-(void)menuControllerWillHide:(NSNotification *)notification{
//re-register menuControllerWillShow
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(menuControllerWillShow:)
name:UIMenuControllerWillShowMenuNotification object:nil];
}
3) Implement tableView Delegates and implement these methods.
- (BOOL)tableView:(UITableView *)tableView shouldShowMenuForRowAtIndexPath:(NSIndexPath *)indexPath {
cell = (TableViewCell*)[tableView cellForRowAtIndexPath:indexPath];
return YES;
}
-(BOOL)tableView:(UITableView *)tableView canPerformAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender {
return NO;
}
- (void)tableView:(UITableView *)tableView performAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender {
// required
}
4) Setup the cells (subclassing UITableViewCell) with
-(BOOL) canPerformAction:(SEL)action withSender:(id)sender {
return (action == #selector(copy:) || action == #selector(test:)); } /// this methods will be called for the cell menu items
-(void) test: (id) sender {
NSLog(#"test"); }
-(void) copy:(id)sender {
NSLog(#"copy"); }
