问题 So I have dynamic tableview and each row have play image. If I select the row image will change to pause icon. But what if I select another row, I need the image on previously selected row to have play icon again. How to handle such functionality? All I have is: class ViewController: UIViewController { var stations = [ (stationIcon: "rr_icon", stationName: "Radio1", urlString: "http://.._320", isPlaying: false), (stationIcon: "mm_icon", stationName: "Record2", urlString: "http://../_320",

问题 I have a table view with a bunch of different sections and dynamic number of rows in each section. In the very first section I have a cell to 'select all'. Is there a quick and easy way to manually select all the cells, so the code in their didSelect triggers and next time the user presses one of the cells it triggers their didDeselect ? The only way I can think of right now is to loop through all the sections, and in each section loop through 0 < indexPath.row < section's data array count

问题 I am having trouble getting the didSelectRowAt method to work for a TableView inside of a regular ViewController . I have already made sure that the delegate and data source for the table are set in the ViewController code. This ViewController populates the tableview cells with results from a search query to an API , and the rendering of cell data is working fine. It's just the didSelectRowAt method that is not registering. I did try manually adding the same delegate information on the Main

问题 (Xcode6-beta3, Swift, iOS8, iPad) In an iPad split-view controller, how do I link the Master View Controller to the Detail View Controller? In other words, when the user taps on an item on the left, how do I change the view on the right? I know that in didSelectRowAtIndexPath, I need to call a method... but how do I call a method in the Detail View Controller from the Master View Controller? Example Imagine an app to display information on different types of cheeses. We begin by dragging a

问题 In my iPhone app I have one messaging screen. I have added UITapGestureRecognizer on the UIViewController and also I have a UITableview on the screen. I want to select the UITableViewCell but I can't select the UITableView because of UITapGestureRecognizer .

Could anyone please help me to work on both tap gesture and UITableView:didSelectRowAtIndexPath: . Thanks in

问题 I have viewDidLoad (of next tableView) being called before didSelectRowAtIndexPath (of current tableView ). I am using a 'singleton' to hold my model and up to now this has been working quite well. I am trying to pass on the row selected in the current table in didSelectRowAtIndexPath to the destination tableview (they are linked by a segue in storyboard) by setting by the variable in didSelectRowAtIndexPath . However the viewDidLoad of the destination tableview is called before I can set the

First tab = Quote ; Second tab = Categories ; Third tab = Settings * The Settings tab is a UITableView with 3 sections, and 2 cells in each section. Problem : I
