I've seen a fix that was something like this: [rootController dismissModalViewControllerAnimated: YES]; [[UIApplication sharedApplication] beginIgnoringInteractionEvents]; [self

问题 I have a UITextField in a Landscape view, and when I press the 'dismiss keyboard' button in the lower right of the UIKeyboard view, the keyboard does NOT disappear. Is there a way to programmatically listen for when this key was pressed? Or is there a connection I am not seeing that will make this keyboard go away? This is iOS 4 and XCode 4. Thanks. 回答1: I had same problem today and I wondered, wy it works in Apple's KeyboardAccessory Sample Code. So I did reverse engineering. The

问题 My iPad app has several data gathering popovers, and I want to be able to disable the dismissal of the popover by touching outside of it, I then will use a button to quit the popover at the users discretion. The app looks great, the popovers work fine, and I have a button inside them that quits nicely. Only I can't find a way of disabling dismissal in Swift, lots of posts on obj-c but nothing in Swift. Does this mean that the functionality is no longer available? I would greatly appreciate
