uitableview

问题 I want to implement this code in Swift. I got the following code for it in Objective-C from these questions: Change the color of default red color delete button in UITableViewCell when swiping rows or click on edit button Customize the delete button in UITableView - (void)willTransitionToState:(UITableViewCellStateMask)state{ [super willTransitionToState:state]; if ((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask) { for (UIView

问题 I'm new to Swift and iOS programming and I'm having a play with making some simple apps. I am trying to build a master-detail app. In the master view I've given the tableview two sections and I've set the content of the table view to "static cells". Initially I gave each section 3 rows and was able to successfully run the app with the following code in the mainviewcontroller file: override func numberOfSectionsInTableView(tableView: UITableView) -> Int { return 2 } override func tableView

问题 Im implementing an app that shows some Twitter data, when is working on wifi is ok, but on 3g crashes, I have come to the conclusion that is because the NSURLRequest that fetchs the data that populates the table takes longer to load so the table ends up calling an object for key, when the keys havent even loaded, So the question is, - how can I know when the NSURLRequest finished loading? [I checked the Class Reference but didnt see it??] Thanks a lot! 回答1: The delegate methods are invoked on

问题 When I try to customise a tableView cell, I found this error. "Get output frames failed, state 8196" I just have no idea it is the error from realm or from my customise tableView cell. class StudentTableViewController: UITableViewController { let realm = try! Realm() var student: Results<StudentName>? var selectedClass: ClassName? { didSet { load() } } var selected: String = "" override func viewDidLoad() { super.viewDidLoad() navigationController?.title = selected tableView.register

问题 I have a very strange problem,I don't know whether it is awkward to normal behavior of cells or not,it seems as if it is so!Hence I am giving it up to some one who can answer, apologize if any thing stupid in asking this question.Normally,when we touch a table view cell,what happens is it navigates to a view controller/a controller that is coded.Now what's strange here is it is not responding to selection,or touch.I have checked whether or not allows selection while editing is selected in IB

问题 I'm having trouble with the following code below, which basically is instantiating an extend uitableviewcell from a storyboard. The problem I'm having is that it seems leftMenuCell is never equal to null, and thus never enters the initiating block. What am I doing wrong? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"LeftMenuCell"; MenuCell *leftMenuCell = [tableView dequeueReusableCellWithIdentifier

问题 I've created a custom table view cell in my iPhone app through the following steps. In my storyboard, I created a sample cell, dragged in a UILabel and a UIImageView . Added new files, which I made a subclass of UITableViewCell . In Interface Builder, I selected my cell and I assigned its class as the class I just created in step 2. In the code for my custom table view cell, I created two IBOutlet properties and connected them to my UILabel and UIImageView in the storyboard. My custom table

问题 i'm trying to update my UITableview but when i call [tableView reloadData]; the table doens't update, after i scroll the tableview above the name of the cell while be changed. But it's not adding a new row or something like that. -(void)update { [tableView reloadData]; NSLog(@" %i", [tableData count]); } The nslog it's returing 1 when i add a row it's returning 2 but the table is not updating. - (void) refresh:(id)sender { NSString *jsonString = [NSString stringWithContentsOfURL:[NSURL

问题 Everything works fine when the view that holds my table is the main (first) view. However, when it's not the first view and I switch into that view, my table does not load data and I get an empty table . Using NSLog I can tell that the program is not invoking numberOfRowsInSection and cellForRowAtIndexPath . I have <UITableViewDataSource, UITableViewDelegate> , IBOutlet UITableview *tableView all declared. They are also connected in the InterfaceBuilder. I tried using viewWillAppear and
