loading list of nearby places iOS 7 using simulator - ios

I am using MapKit and I'm trying to retrieve a list of nearby places based on the users current location and after that, I am trying to display them in a TableView. However, when using the iOS simulator, no places show up. I went to simulator->debug->location->Apple so shouldn't results pertaining to THAT location show up? I'm confused. Here is my code:
- (void)viewDidLoad
{
[super viewDidLoad];
//[self CurrentLocationIdentifier];
[self performSearch];
_m= [MKMapItem mapItemForCurrentLocation];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return _places.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"placeCell";
PlaceTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
long row = [indexPath row];
cell.placeLabel.text = _places[row];
return cell;
}
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
[super tableView:tableView didDeselectRowAtIndexPath:indexPath];
int rowNo = indexPath.row;
_place = [_places objectAtIndex:rowNo];
}
- (void) performSearch {
MKLocalSearchRequest *request =
[[MKLocalSearchRequest alloc] init];
request.naturalLanguageQuery = _m.name;
_places = [[NSMutableArray alloc] init];
MKLocalSearch *search =
[[MKLocalSearch alloc]initWithRequest:request];
[search startWithCompletionHandler:^(MKLocalSearchResponse
*response, NSError *error) {
if (response.mapItems.count == 0)
NSLog(#"No Matches");
else
for (MKMapItem *item in response.mapItems)
{
NSString *n = item.name;
[_places addObject:n];
}
}];
}
#end

You need to add a bunch of log statements and look at what is displayed in the console (or add breakpoints and use the debugger, but I'm guessing you don't know how to do that.
Add a log statement at the beginning of your performSearch that displays the _m.name that you are using as your search string. Add a log to the top of your completion handler so you know that it's called.

Okay so for some reason the results started appearing after I changed the type of "row" in cellForRowAtIndexPath from long to int and instead of [indexPath row], I changed it to indexPath.row

TableViewController doesn't display information on table

Hi when I do for loop to get all documents from a collection. I add the car object to the NSMutablearray and when I debug i can see that the objects are being added to the array but when i want it to display in the table and get the count of the array I call the [self.mycars count] to get the count but the count is nil and i cant get information from the cell.textLabel.text = vehicle.name; so what am i doing wrong.
#import "TableViewController.h"
#import "Car.h"
#import "Vehicle.h"
#interface TableViewController ()
#end
#implementation TableViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
self.db = [FIRFirestore firestore];
self.myCars = [[NSMutableArray alloc] init];
[[[[self.db collectionWithPath:#"users"] documentWithPath:[FIRAuth auth].currentUser.uid]
collectionWithPath:#"cars"] getDocumentsWithCompletion:^(FIRQuerySnapshot *snapshot, NSError *error) {
if (error != nil) {
NSLog(#"Error getting documents: %#", error);
} else {
for (FIRDocumentSnapshot *document in snapshot.documents) {
NSLog(#"%# => %#", document.documentID, document.data);
Car *car = [[Car alloc] initWithCarName:[document valueForField:#"carname"] andCarStyle:[document valueForField:#"carstyle"]
andCarColour:[document valueForField:#"colour"] andCarYear:[document valueForField:#"caryear"]
andCarDoors:[document valueForField:#"doors"] andCarSeat:[document valueForField:#"seat"] andCarWheels:[document valueForField:#"wheels"]
andCarTankCapacity:[document valueForField:#"tankcapacity"] andCarHorsePower:[document valueForField:#"horsepower"] andCarModelName:[document valueForField:#"modelname"]];
NSLog(#"Car name:%#", car.name);
[self.myCars addObject:car];
}
}
}];
}

// Configure the cell...'
Vehicle *vehicle = [self.myCars objectAtIndex:indexPath.row];
cell.textLabel.text = vehicle.name;
return cell;
}
#end
You need to reload data manually after changing/updating your datasource (self.myCars in this case) which mean you need to add [self.tableView reloadData]; after for loop. If it still is not working, you might want to check if self.myCars is initialized yet.

PFQueryTableViewController loading for 5 minutes

I followed this tutorial here https://parse.com/questions/using-pfquerytableviewcontroller-for-uitableview-sections and was able to create a beautiful table with sections, but it takes forever to load! Well, not forever, 5 minutes to be exact. My table in parse has 587 rows in it and it takes 5 minutes to load all of the objects into sections. The first few minutes shows the "Loading..." on the blank view, then there is an empty tableview, and finally all of the objects load. Is there a reason something like this is taking so long? I can't have my users wait 5 minutes for something to load. This tableview is displayed during the register process. It is a list of schools and the new user must select which school they are from. The sections organize the schools based on location, and there are about 30 sections. Any suggestions for getting this to load faster?

Yeah, you're not going to be able to make this fast enough as-is... The client should not have to download every object first, and scrolling lists with 500+ items are not a good user experience. Perhaps you should have an initial screen where they pick some subset, and then they can query a smaller set of data on the next screen. What you're currently using as a section might be a good candidate.

how to order cells by date created and alphabetically using Parse database in Xcode 5?

I am building a database style app using Parse in Xcode 5 and want to be able to order all the cells by date created. I also want to then be able to change this to alphabetical order when I click an option of a segmented control (by date order being the default). How do I do this?

Many thanks in advance!
As a guideline, you have to sort you datasource (probably NS(Mutable)Array or NS(Mutable)Dictionary) as per your criteria and once the datasource is sorted out you need to call:
[yourTableView reloadData];
Later when you have to change the sort criteria to alphabetic order (may be through segmented control) sort data source in alphabetic order instead of date created, and don;t forget to reload your table again.
Below are some examples:
Sort in descending order
Sort using custom objects

UITableView cells not being populated [duplicate]

ios - why does my UITableView not get populated with comments

Closed 9 years ago.
I am getting a list of some ShoppingLists through a WCF call.

Nothing happens when i run the app in Xcode. I can see in the log window that the log
NSLog( #"new list - number of news :: %u", [_shoppingList count]);
does return a value (4), but the NSLog i have made in the CellForRowAtIndexPath method does not get printed. I also have a breakpoint in there, that isn't reached. Why is it not getting to the method?
These methods, numberOfSectionsInTableView and numberOfRowsInSection are important to determine what number of data the TableView should show.. it should look something like this:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1; // the number of different sections in your table view
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [_shoppingList count]; // the number of data in your shopping list
}
You should not comment out these methods: numberOfSectionsInTableView and numberOfRowsInSection.
At least numberOfRowsInSection is required and must return the number of rows you want/need.
As far as I got it, this should be _shoppingList.count in your case.
because you commented out these methods: numberOfSectionsInTableView and numberOfRowsInSection, your tableView would be 0 section and 0 row,so the method
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath
did not be accessed.

well 1) numberOfSections is 0. to see something it should be one IIRC
think thats it but havent double checked
Assuming your data array is built up correctly, your mistake in is your numberOfSections methods. Currently, it returns 0, which tells the UITableView that there are currently no sections to be displayed… ever.
You can either return 1; there or remove the entire method altogether. The default implementation, which you inherit from UITableViewController, also returns 1 by default.
My advice would be to remove the method, as that keeps your own code cleaner. You can always implement it in a later stage, when you might actually need it.
