I have two questions regarding Remote Control Events on iOS: I know that music applications are registered to remote control events and then can receive such events from the iPhone's player widget. Let's say I want my app to fire such events, is that possible? How does headphones for example generate those events? Without private API, you cannot send remotecontrol event to your application. The reason is we cannot create such an Event (UIEvent) to send out by using: [[UIApplication sharedApplication] sendEvent:anEvent]; You can, however save a registered event then play back by calling the

Is there a way to gain the type of touch gestures that triggered a UIEvent? So, let's say I intercept a gesture with hitTest:withEvent:. How do I identify what kind of touch (pinch, tap, swipe, etc.) happened that triggered this method? I can gain the type of remote events from the UIEvent subtype, and even if the device was shaken, but there is no parameter for touch events... How do you identify those? You have to do touch analysis on your own. It is not that difficult, but it is not done for you. Here a sample from some code I am actually using. It is not meant as a full-scale solution. It

I have an requirement that to handle headphone play/pause button events in foreground. How ever I am able to handle the same scenario in background using the below code if ([[UIApplication sharedApplication] respondsToSelector:@selector(beginReceivingRemoteControlEvents)]){ [[UIApplication sharedApplication] beginReceivingRemoteControlEvents]; [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:NULL]; [self becomeFirstResponder]; NSLog(@"Responds!"); } Please help with an explanation or sample code if possible. I have done lots of research but no help. There is another

I have a subclass of UIView on top of a UITableView . I am using the UITableView to display some data and, at the same time, I would like to overlay an animation that follows the finger (for instance, leaving a trail). If I get it right, I need the touch events to be handled both by the UIView subclass and the UITableView . How can I do that? Is it possible to have, ie, touchesMoved being triggered on the UIView subclass and then on UITableView ? Thank you so much for any help. The way I have solved this problem is in a way that is not that clean, but it works. Please let me know if there's a

How would you allow a UIGestureRecognizer of a UIView to receive a touch event but also make sure that another, underlaying/overlaying UIView also receives that very same touch event? Lets say I have got the following view-hierachie: Views A (blue) and B (red) are both subviews of the same superview (gray). In other words, they are both siblings and the order decides on which of them covers the other. Option 1: View B (red) has a regular UIButton as its subview. Option 2: View A (blue) has a regular UIButton as its subview. Given Option 1 for the sake of explanations: View A (blue) has a
