As context-menu and paste function are so convenience in not only web-appli and but also self-appli with freely string send. We’d like to introduce how to implement.

• How to appear menu ?
  • Event capture
    

    Most important issue in menu functionality as how to capture the event. You can google with “touchs began”, many pages would be displayed. However, we use little trick as “keyboard show”

    Objective-C

    - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; self.navigationItem.title = _detailItem.name; // NSURL *url = [NSURL URLWithString:@"http://www.yahoo.co.jp"]; NSURL *url = [NSURL URLWithString:_detailItem.address.loginURL]; NSURLRequest *req = [NSURLRequest requestWithURL:url]; [myWebView loadRequest:req]; [self copyToID]; // Start observing if (!_observing) { NSNotificationCenter *center; center = [NSNotificationCenter defaultCenter]; [center addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil]; [center addObserver:self selector:@selector(keybaordWillHide:) name:UIKeyboardWillHideNotification object:nil]; _observing = YES; } }

    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

    - (void)viewWillAppear:(BOOL)animated {     [super viewWillAppear:animated];     self.navigationItem.title = _detailItem.name;     //    NSURL *url = [NSURL URLWithString:@"http://www.yahoo.co.jp"];     NSURL *url = [NSURL URLWithString:_detailItem.address.loginURL];     NSURLRequest *req = [NSURLRequest requestWithURL:url];     [myWebView loadRequest:req];          [self copyToID];          // Start observing     if (!_observing) {         NSNotificationCenter *center;         center = [NSNotificationCenter defaultCenter];         [center addObserver:self                    selector:@selector(keyboardWillShow:)                        name:UIKeyboardWillShowNotification                      object:nil];         [center addObserver:self                    selector:@selector(keybaordWillHide:)                        name:UIKeyboardWillHideNotification                      object:nil];                  _observing = YES;     } }

    Objective-C

    - (void)keyboardWillShow:(NSNotification *)notificatioin { NSMutableArray* menuItems = [NSMutableArray array]; UIMenuController* menuController = [UIMenuController sharedMenuController]; [menuController setTargetRect:CGRectZero inView:self.view];menuController.arrowDirection = UIMenuControllerArrowDown; [menuItems addObject:[[UIMenuItem alloc] initWithTitle:NSLocalizedString(@"login-ID", @"") action:@selector(menu1:)]]; [menuItems addObject:[[UIMenuItem alloc] initWithTitle:NSLocalizedString(@"login-PWD", @"") action:@selector(menu2:)]]; menuController.menuItems = menuItems;[menuController setMenuVisible:YES animated:YES]; return; }

    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

    - (void)keyboardWillShow:(NSNotification *)notificatioin {     NSMutableArray* menuItems = [NSMutableArray array];       UIMenuController* menuController = [UIMenuController sharedMenuController];     [menuController setTargetRect:CGRectZero inView:self.view];menuController.arrowDirection = UIMenuControllerArrowDown;         [menuItems addObject:[[UIMenuItem alloc] initWithTitle:NSLocalizedString(@"login-ID", @"") action:@selector(menu1:)]];     [menuItems addObject:[[UIMenuItem alloc] initWithTitle:NSLocalizedString(@"login-PWD", @"") action:@selector(menu2:)]];       menuController.menuItems = menuItems;[menuController setMenuVisible:YES animated:YES];         return; }

  • menu setting
    

    Implement menu setting code. We can create context-menu in this part.

    Objective-C

    - (BOOL)canPerformAction:(SEL)action withSender:(id)sender { if (action == @selector(menu1:) || action == @selector(menu2:) || action == @selector(paste:)){ return YES; } return [super canPerformAction:action withSender:sender]; }

    1 2 3 4 5 6 7 8 9

    - (BOOL)canPerformAction:(SEL)action withSender:(id)sender {          if (action == @selector(menu1:) ||         action == @selector(menu2:) ||         action == @selector(paste:)){         return YES;     }     return [super canPerformAction:action withSender:sender]; }

• Paste board handling
  • Use findFirstResponder
    

    findFirstResponder in this software.

    Objective-C

    @implementation UIView (FindFirstResponder) - (UIView *)findFirstResponder { if (self.isFirstResponder) { return self; } for (UIView *subView in self.subviews) { UIView *firstResponder = [subView findFirstResponder]; if (firstResponder != nil) { return firstResponder; } } return nil; } @end

    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

    @implementation UIView (FindFirstResponder)   - (UIView *)findFirstResponder {     if (self.isFirstResponder) {         return self;     }          for (UIView *subView in self.subviews) {         UIView *firstResponder = [subView findFirstResponder];                  if (firstResponder != nil) {             return firstResponder;         }     }          return nil; }   @end

  • menu setting
    

    Detail implementation in this section. String would be sent both web-appli and self-appli.

    Objective-C

    - (void)menu1:(id)sender { [self copyToID]; UIView* firstView = [myWebView findFirstResponder]; if ([firstView respondsToSelector:@selector(paste:)]) { [firstView paste:sender]; } } - (void)menu2:(id)sender { [self copyToPassword]; UIView* firstView = [myWebView findFirstResponder]; if ([firstView respondsToSelector:@selector(paste:)]) { [firstView paste:sender]; } }

    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

    - (void)menu1:(id)sender {     [self copyToID];       UIView* firstView = [myWebView findFirstResponder];     if ([firstView respondsToSelector:@selector(paste:)]) {         [firstView paste:sender];     } }   - (void)menu2:(id)sender {     [self copyToPassword];       UIView* firstView = [myWebView findFirstResponder];     if ([firstView respondsToSelector:@selector(paste:)]) {         [firstView paste:sender];     } }
