These are standart actions for UIMenuController declared http://developer.apple.com/library/ios/#documentation/uikit/reference/UIResponderStandardEditActions_Protocol/UIResponderStandardEditActions.html How can I perform these methods manually, like from another UIMenuItem or whatever? I can't find the right selector:( [self cut:sender]; [UIResponder cut:sender]; [[UIMenuController sharedMenuController] cut:sender]; (void) cut: (id) sender {[super cut:sender];} So far non of these don't work, selector not found. You need to send the action along the responder chain, starting with the "first

I have a UIImage view that responds to touch events. I want to cancel the touch sequence, i.e., further calls to touchesMoved: , if the touch goes outside of certain bounds. How can I do that? I know that in touchesMoved: I can inspect the coordinates of the touch object and ignore it, but what I don't know is how to cancel the sequence altogether. I don't see any method documented in the Apple Developer UIResponder Reference that I can call to cancel a touch sequence. This solution may be a bit kludgy, but you could implement and manually call - (void) touchesCancelled:(NSSet *)touches

I thought when a view is touched or tapped on, its handler get called first, and then its superview's handler is called (propagate upward). But is it true that if the superview's userInteractionEnabled is set to NO, then all subviews and offspring is also disabled for user interaction? What if we want to disable for just the main view but don't want to disable for the subviews? You cant do that, Instead you would change the arrangment of your views like following: Main View-> subViews To Container View -> Main View that you want to set as inactive -> other views that you want to still active

In my App I want to disable the Copy/Paste/Cut of contents that are showed by a UIWebView object. To achieve this, I created a UIWebView subclass and overrode the - (BOOL)canPerformAction:(SEL)action withSender:(id)sender method: #pragma mark - UIResponderStandardEditActions - (BOOL)canPerformAction:(SEL)action withSender:(id)sender { if (action == @selector(copy:) || action == @selector(paste:)|| action == @selector(cut:)) { return _copyCutAndPasteEnabled; } return [super canPerformAction:action withSender:sender]; } Now the user no longer can make such operations, however the UIWebView still

I'm trying to achieve similar positioning behavior as the bottom text input bar in Apple's Messages app. I have tried many approaches, searched high and low and there are many similar questions but none have been satisfactory. To specify: There is a UIToolbar at the bottom of the view The toolbar is to follow the keyboard as the keyboard appears and disappears The toolbar should stay on top of the keyboard when the keyboard is visible When the keyboard is hidden, the toolbar stays ("docked") at the bottom of the view The proposed solutions: Manually animate the toolbar in response to keyboard

I am working with multitouch while writing, So basically what I am doing is, I am writing with hand support, because typically, its how user writes, I followed this link How to ignore certain UITouch Points in multitouch sequence Everything is working fine with single touch, but their is some problem when I write with my hand touching the screen i.e multiple UItouches Below is my code In touches began, I go through all touches and I find the touch with highest y position, below is my code Below is my code -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch* topmostTouch =
