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

问题 In my app, I use Parse. I have it set up like this: - (id)initWithCoder:(NSCoder *)aDecoder { self = [super initWithCoder:aDecoder]; if (self) { // The className to query on self.parseClassName = @"Prayers"; // Whether the built-in pull-to-refresh is enabled self.pullToRefreshEnabled = YES; // Whether the built-in pagination is enabled self.paginationEnabled = YES; // The number of objects to show per page self.objectsPerPage = 20; } return self; } - (PFQuery *)queryForTable { PFQuery *query

问题 I have three different types of cells in a tableViewController. I get which type of cell to have and an objectId of an item from a different class. I then go to each cell in the cellForRowAt method and load whatever the data is. This method has led me to 2 problems: 1) the dynamic height of one of the cell does not work because it's label's text is not found until after the cell is made. 2) All the cells have a "jumpy" (I can see the rows being populated as I scroll down, I guess because its

问题 I have two classes User and Post . The User class has a userType field and I want to retrieve all of the posts from a given userType lets call them group x. In the Post class I have a pointer to the User class. I was trying to do something like, first retrieve all user Ids for the type of user I want: PFQuery *queryUser = [PFQuery queryWithClassName:kFTUserClassKey]; [queryUser whereKey:kFTUserTypeKey equalTo:kFTUserTypeX]; [queryUser whereKey:kFTUserLocationKey nearGeoPoint:nearGeoPoint

问题 Currently Im following this tutorial http://www.appcoda.com/ios-programming-app-backend-parse/ But I want the tableviewcontroller to be refresh with new data when data from parse.com is update automatically. I don't want the user to always have to pull to refresh. or maybe having time refresh every minute? I heard about reloaddata but how to implement the code? - (id)initWithCoder:(NSCoder *)aCoder { self = [super initWithCoder:aCoder]; if (self) { // The className to query on self

问题 I've imported all the frameworks required but from that point on I don't quite know what to do (I'm new to Swift and no absolutly nothing about Objective C). Parse docs aren't in Swift yet so can someone please provide me with a starting point? I've initialized my view controller (which doesn't appear when I run the app, I just get a black screen; but based on this video, I should see a table: https://parse.com/tutorials/parse-query-table) func application(application: UIApplication,

问题 I have created a PFObject named UserInfo. Everything saves to Parse correctly, but when I go to retrieve it I keep getting errors. Here is my code below. PFQuery *query = [PFQuery queryWithClassName:@"UserInfo"]; [query whereKey:@"user" equalTo:currentUser]; [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { if (error) { NSLog(@"Error: %@ %@", error, [error userInfo]); } else { self.userInfo = objects; NSLog(@"%@", self.userInfo); self.locationDisplay.text = [self

问题 I am trying to set a pointer from an object in "Classes" to an object in "Schools". When I do so, I get this error: invalid type for key school, expected *Schools, but got string (Code: 111, Version: 1.12.0) I know that the error is saying that it expects a pointer for class, "Schools", but it got a string instead. Here is my code: let schoolObjectIdQuery = PFQuery(className:"Schools") schoolObjectIdQuery.whereKey("school_name", equalTo: "\(PFUser.currentUser()!.objectForKey("school_name")!)"

问题 I try to get the number of queries I found in background. So I use countobjects method to get the number, but system has warning about it "A long-running operation is being executed on the main thread." PFQuery *query2=[PFQuery queryWithClassName:@"Comments"]; [query2 whereKey:@"Name" equalTo:globalName]; NSInteger CommentPoint=query2.countObjects; so i change to this method, but i can't get numbers of count print in my console. [query2 countObjectsInBackgroundWithBlock:^(int count, NSError
