uipopovercontroller

问题 I have a matrix of data (players) displayed in a UICollectionView . I want details on a player to display in a popover view when the user touches a cell.

问题 I am trying to fix someone's code and am running into a problem. Here is the situation: I have a full screen UIViewController that has a bottom bar button. When I press that button, it shows a popup view controller in the bottom left of the screen.

That new view controller is a UITableView that can have some large number of elements. The problem is that

I want the popovers to stay persistent (only initialize once) what is the best way of archiving this. If I had

问题 I am trying to set up a popover to point to a UIButton in a view that is used as a "inputView" to a UITextView. I can get everything to work and the correct data is going into the UIPopoverController. But it is exhibiting a behavior that is not what I expected. So here is what I have. The following method is written in a UIView subclass that is the inputView of the UITextView and is also the view in which the button resides. - (IBAction)buttonTouchDown:(id)sender { UIButton *button =

问题 I'm banging my head for some time due to this issue. I precise my scenario in detail. I have a table view where I can add data using a popover which gets displayed on clicking the '+' button in the navigation bar. I get the values from the popover but where I'm stuck is, the data received is not getting reflected in the tableview. If I move back and forth it gets displayed.
