I'm trying to display a custom UIMenuController when a User long presses on a cell in a grouped UITableView. However, I can't seem to get the UIMenuController to display after successfully detecting the long press. Any help is greatly appreciated.
MyViewController.h
@interface MyViewController : UIViewController <UITableViewDelegate,UITableViewDataSource>
UITableView *table;
@property (nonatomic, retain) IBOutlet UITableView *table;
@end
In the cellForRowAtIn开发者_StackOverflowdexPath I attach my Long Press Gesture Recognizer
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:SectionsTableIdentifier] autorelease];
UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)];
[cell addGestureRecognizer:longPress];
[longPress release];
Here is my handleLongPress action method
-(void)handleLongPress:(UIGestureRecognizer *)longPress {
if (longPress.state == UIGestureRecognizerStateBegan) {
CGPoint pressLocation = [longPress locationInView:self.table];
NSIndexPath *pressedIndexPath = [self.table indexPathForRowAtPoint:pressLocation];
UIMenuItem *first = [[UIMenuItem alloc] initWithTitle:@"Save" action:@selector(saveRecent)];
UIMenuItem *second = [[UIMenuItem alloc] initWithTitle:@"Edit" action:@selector(editQuery)];
UIMenuController *menuController = [UIMenuController sharedMenuController];
menuController.menuItems = [NSArray arrayWithObjects:first,second,nil];
[menuController setTargetRect:longPress.view.frame inView:longPress.view.superview];
[menuController setMenuVisible:YES animated:YES];
[pressedIndexPath release];
}
}
The Action methods for the Edit and Save just display a UIAlertView. I also implemented the below method to ensure that when the UIMenuController is displayed only Save and Edit options will be present
-(BOOL)canPerformAction:(SEL)action withSender:(id)sender {
BOOL canPerform = NO;
if (action == @selector(saveRecent)) {
canPerform = YES;
}
if (action == @selector(editQuery)) {
canPerform = YES;
}
return canPerform;
}
I'm also claiming MyViewController to be first responder
-(BOOL)canBecomeFirstResponder {
return YES;
}
I believe you need to have a view claiming firstResponder status in order to present the UIMenuController. I don't see that happening in your code.
I wrote up directions for using the UIMenuController as an answer to this question:
