TableViewCell cell!.titleLabel!.text = sections[indexPath.section].objects[indexPath.row].name cell!.datetimeLabel!.text = "on " + sections[indexPath.section].objects[indexPath.row].date return cell! } func tableView(tableView: UITableView, heightForHeaderInSection

问题 I'm trying to build a grouped UITableView cell like the table in user details in Twitter's app (former Tweetie app). It's a cell with two sides, and you can select any of them separately (and the background turns blue, like a rounded button). Anyone did something like it or know how they made it? A screen shot from the view (it's the following, tweets, followers and favorites cells) 回答1: I was wanting to do the same in my own app, but I was also a bit clueless on how this was done in the

问题 I'm working with an UICollectionView . As dequeueReusableCell(withReuseIdentifier:for:) expects You must register a class or nib file using the register(_:forCellWithReuseIdentifier:) method before calling this method , I added a line in my viewDidLoad func as self.collectionView!.register(PhotoCollectionViewCell.self, forCellWithReuseIdentifier: reuseIdentifier) Now when I'm using the cell for dequeuing and configuring, I'm getting error and app crashes. fatal error: unexpectedly found nil

问题 I literally could not find a single tutorial that showed me how to build an app that uses static cells; with clickable cells. Based on few out dated posted and object-c answers, I've put something together. My issue is, when I click on a cell, I get staticDemoTableCell is has no member present . I have embedded a Table Controller in my UIViewController. For that cell (only one so far), I've created a class: class staticDemoTableCell: UITableViewCell, UITableViewDelegate { @IBOutlet weak var

问题 I've been stuck with this problem for days, so I'd be really happy if someone could help. I'm trying to create a dynamic UITableView, for which I created a custom UITableView subclass and I've created a custom UITableViewCell subclass as well, because I need several UILabels and a UIButton in each cell. The cell is created, but the problem is that the value of the labels is always nil, hence the cell isn't displayed properly. This is, how the storyboard looks like, and this is what I see

问题 I have a tableView with static cells. The cell contains an ImageView which fills it completely. And I have another smaller ImageViews atop. I position this ImageViews with constraints. I have a question about resizing the constraints. How can I set different constraint constants for different devices sizes without programming if/else loops. Is there a way to set it in the storyboard? I have a leading constraint to parent layout for example with an constant value of 10. This is okay for the

问题 I create UIBarbUttonItem inside UITableView cell programmatically like this : func setupChildrenPicker(){ let chooseButton = UIBarButtonItem(title: Wordings.BTN_CHOOSE, style: UIBarButtonItemStyle.done, target: nil, action: #selector(self.pickerChildrenDonePressed)) } func pickerChildrenDonePressed(){ print ("pickerChildrenDonePressed") } override func awakeFromNib() { super.awakeFromNib() setupChildrenPicker() } but when I click that BarButtonItem, it not called pickerChildrenDonePressed()

问题 Explanation: I have a UITableView that is being populated from JSON. The purpose of the tableview is for the user to select individual row records and have the checkmark accessory appear as a result. The issue is that while I can get the checkmark to appear for whichever row is selected the checkmark is applied to the row, not the record itself. For example, if I have two rows in the tableview and I select the first row, a checkmark is applied to it, but after updating the API to remove the

问题 I have a tableview with a label and two buttons on each cell. At the moment I have this code that does a swipe to delete. - (void) tableView: (UITableView *) tableView commitEditingStyle: (UITableViewCellEditingStyle) editingStyle forRowAtIndexPath: (NSIndexPath *) indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [appointments removeObjectAtIndex: indexPath.row]; // manipulate your data structure.
