pfquery

问题 I have a subclass of PFQueryTableViewController that I am trying to show in a container view (as a subview). My problem is that I cannot get the custom cells to show in the tableview. I have verified the following via debugging: The tableview is being added to the parent view The tableview is a PFQueryTableView Controller as it includes the default pull to refresh The PFQuery is returning the correct number of objects The CellForRowAtIndexPath method is being called and iterating through the

问题 Variable in a User class as a string. Using this variable as a key for a PFQuery and use it to filter out the users that don't have it.I need to skip users that don't have it and add the users that do to the VC display. Here is my code so far: In the VC where the variable is stored I have: var genreSearch: NSString? after viewDidLoad in a cell I have: let genreSearch = table_data[indexPath.row] userDefaults.setObject(genreSearch, forKey: "genre") print(genreSearch)` Then on the VC where the

问题 I am trying to query all of the Parse users in my database and then display each individual user in their own cell in a tableview. I have set up my tableview, but I'm stuck on saving the user query to a string array that can be used within the tableview. I have created a loadParseData function that finds the objects in the background and then appends the objects queried to a string array. Unfortunately I am given an error message on the line where I append the data. Implicit user of 'self' in

问题 I'm trying to figure out how to get the benefits of the PFQueryTableViewController to work inside of a a regular UIViewController that has a TableView embedded in it. Because apparently I can't load data from parse onto my TableView. It just pops up as a blank tableView with none of my information from Parse in it unless the code is ran on a UITableViewController, then it has no problems. But I'm trying to get my program to run on a Table View thats in a UIViewController. And whenever I

问题 I'm writing an iOS-App using Parse.com as a backend. In the - (PFQuery)queryForTable method of my PFQueryTableViewController I'm retrieving a set of data from Parse, but I'm unable to cache this query in order to support functionality when the device is currently offline. The method looks as followed: - (PFQuery *)queryForTable { PFQuery *query = [PFQuery queryWithClassName:self.parseClassName]; [query whereKey:@"city" equalTo:[[NSUserDefaults standardUserDefaults] objectForKey:@"city"]]; //

问题 I'm trying to do a simple query in xcode using the Parse SDK where I am showing products to users but i don't want to show them products they've already "liked." So I have two tables in Parse that I'm using: - Products: has an objectId - Likes: contains columns: Like (says yes/ no), Pointer to a product, Pointer to a user Any my code is: //query will get products that the user has liked PFQuery *likeQuery = [PFQuery queryWithClassName:@"Likes"]; [likeQuery whereKey:@"User_Obj" equalTo:[PFUser

问题 I am trying to download an array from Back4Apps.com (Parse.com equivalent). The below displays no errors, but when it gets to the line "downloadQuery.findObjectsInBackground { (objects, error) in", it simply skips over the rest of the code to the end of the function. I have tested the "username" and it seems to be correct. I am certain the class and subClass names are correct. The parse parameters are correct and I already have many other parse functions working. Any suggestions where to look

问题 How can I query after a specific row where the objectId is equal to a objectId I have stored? This is my query code: func queryStory(){ let query = PFQuery(className: "myClassStory") query.whereKey("isPending", equalTo: false) query.limit = 1000 query.orderByDescending("createdAt") query.findObjectsInBackgroundWithBlock { (posts: [PFObject]?, error: NSError?) -> Void in if (error == nil){ // Success fetching objects for post in posts! { if let imagefile = post["userFile"] as? PFFile { self

问题 I have PFQueryTableView with UISearchBar to search users from my user class on Parse server but I never get it working. Here is my code: SearchViewController.h #import <Parse/Parse.h> @interface PAWUserSearch1ViewController : PFQueryTableViewController @end SearchViewController.m #import "SearchViewController.h" #import "PAWAppDelegate.h" @interface SearchViewController () <UIGestureRecognizerDelegate, UISearchBarDelegate, UISearchDisplayDelegate> @property (strong, nonatomic) IBOutlet

问题 I need to check for, and then show, the number of objects in a Parse class in a fixed tableView, each object has a "guide" keyword, and each row of the tableView is named after those keywords. problem: Can't add data to the array my idea is to search for them, put result in an array: var totalOfTotalArray : [Int] = [] and then, in order to show numbers one by one, each row will have: switch indexPath.row { cell.guideNumberOfMexLabel.text = String(self.totalOfTotalArray[indexPath.row]) } this
