问题 I am using CloudKit to store a few arrays, then use the arrays to fill a table. I am reloading the table, but it will not show any data. It should be connected to iCloud because I am still able to add to the database. Code is shown below: import UIKit import CloudKit var selectedCellName = "" class explore: UIViewController, UITableViewDataSource, UITableViewDelegate { @IBOutlet var tableView: UITableView! var groupNames = [String]() var Group = [CKRecord]() override func viewDidLoad() {

问题 Because I had some troubles using the default separator line between the UITableViewCell I want to use my own. Therefore I'm using auto layout. C# is the language I used. You can of course provide solutions in Objective-C. In the constructor of my custom cell I add my view UIView : separator = new DividerView (); ContentView.Superview.AddSubview (separator); One has to add it to the superview otherwise it doesn't cover the accessory area. In updateConstraints I set up my constraints:

问题 I have the Main View Controller which has a collection view with its collection view cells each initialized as a tableView to serve multiple rows inside of that collection view cell. If you're getting confused, below is the snapshot of the current state. The problem is when I try to tap a tableView row cell to open another view controller, It fails and a selected state of table view cell is shown. Here is the snapshot. //HomeCollectionViewCell.swift class HomeCollectionViewCell:

问题 Setup : I have a scrollview with a label, uiimage, and a tableview (grouped) nested within. The label, uiimage, and tableveiw are populated by a webservice. The last section in the grouped table view contains text that will never be the same and could be as long as 5 characters to 250+. Also, this view is pushed from a basic tableview (so it has a navigation bar. If that matters at all). Expected : The tableview should extend in height depending on the length of the content received from the

问题 I have a UIButton receiving an action in each section header in a UITableView . When a tap occurs, I need to be able to get if it hit something that is not a cell so I set his code: UITouch *touch = [[event touchesForView:deleteButton] anyObject]; CGPoint location = [touch locationInView:self.tableView]; if (![self.tableView indexPathForRowAtPoint:location]) { //stuff } Everytime I tap a section header button, the function returns me the index path of the first row from the corresponding
