reloaddata

I am facing problem in my app - you can post and edit your favorite places. After posting a post, or editing a specific post ( UITableViewCell ), UITableview is reloaded. My problem is: the UITableview scrolls to the top after reloading. But that's not what I want. I want my view to stay on the cell / view where I was. But I don't know how to manage that. Could you help me? Igor's answer is correct if you are using dynamically resizable cells (UITableViewAutomaticDimension) Here it is in swift 3: private var cellHeights: [IndexPath: CGFloat?] = [:] var expandedIndexPaths: [IndexPath] = [] func

I have a class that runs similar to the AFHTTPSessionManager component of this tutorial http://www.raywenderlich.com/59255/afnetworking-2-0-tutorial However, [self.tableView reloadData] is not working for me. I have the manager implemented as so: -(void) refresh{ manager = [[AFHTTPSessionManager...] iniwithBaseURL:...]; [manager Get:... parameters:... success:^(NSURLSessionDataTask *task, id responseObject){ //test success values in responseObject if(test){ //Get table data [self.tableView reloadData]; } } .... } However if I run [self.tableView reloadData] in a separate function afterwards,

Iam having a UItableview which is populated from array and a drop down list. If i select any row of drop down list the array will be inserted with new values and tableview should reload.

I got a separate thread that creates a UIView object, inserts it into the UITableView's data source and then call reloadData on the UITableView. However, since it is a separate thread, it cannot call reloadData directly, it needs to make the mainthread do it... but how do you tell the mainthread to do it? Thanks [self.tableView performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO]; You can use dispatch async, this method allows you to marshal worker thread to blocks of in-line code rather than methods using performSelectorOnMainThread: dispatch_async(dispatch_get

I have a bit of a problem with my iOS app in xcode. I have a UITableView that loads a few hundred cells. When I scroll down to a specific cell and drill down to detailedviewcontrollers and return again the master view table has returned all the way to the top. I've had a look at the following 2 questions that are similar. How can I get the UITableView scroll position so I can save it? Setting scroll position in UITableView I still can't get these to work. I'm not the most experienced coder so I'm really struggling with this. I know things like viewWillDisappear and viewDidAppear need to be

I believe I'm having an issue where my closure is happening on a background thread and my UITableView isn't updating fast enough. I am making a call to a REST service and in my closure i have a tableView.reloadData() call but it takes a few seconds for this to happen. How do I make the data reload faster (perhaps on the main thread?) REST Query Function - using SwiftyJSON library for Decoding func asyncFlightsQuery() { var url : String = "http://127.0.0.1:5000/flights" var request : NSMutableURLRequest = NSMutableURLRequest() request.URL = NSURL(string: url) request.HTTPMethod = "GET"
