Get an array from Parse query [duplicate] - ios

Question

This question already has an answer here:
Pass data from Parse tableview to WatchKit
(1 answer)
Closed 8 years ago.
I'm using Parse to create this table view, and am trying to figure out how to get the Parse table data into an array, so I can pass it into the WatchKit InterfaceController to show the exact same thing?
So I want to show in the WatchKit interface exactly what shows in the iPhone interface.
Here is what I have, let me know if I can add anything that would be helpful:
TableVC.m:
- (id)initWithCoder:(NSCoder *)aCoder
{
self = [super initWithCoder:aCoder];
if (self) {
self.parseClassName = #"na";
self.textKey = #"dateTime";
self.pullToRefreshEnabled = YES;
self.paginationEnabled = NO;
}
return self;
}
- (PFQuery *)queryForTable
{
PFQuery *query = [PFQuery queryWithClassName:self.parseClassName];
return query;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object
{
static NSString *simpleTableIdentifier = #"RecipeCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
UILabel *homeLabel = (UILabel*) [cell viewWithTag:101];
homeLabel.text = [object objectForKey:#"test"];
UILabel *dateLabel = (UILabel*) [cell viewWithTag:102];
dateLabel.text = [object objectForKey:#"dateTime"];
return cell;
}
Parse data:
TableVC.m:
I already have the basic WatchKit files and Storyboard set up. I hard coded an array to test that it was generally working. But now I just need to get the data from Parse into there, and not sure if I need to do a query and then turn that into a public array?
EDIT:
Here is my query:
PFQuery *query2 = [PFQuery queryWithClassName:#"nba"];
[query2 findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
// The find succeeded.
NSLog(#"Objects 2: %#", objects);
}
} else {
// Log details of the failure
NSLog(#"Error 2: %# %#", error, [error userInfo]);
}
}];
Here is my NSLog:
NSLog(#"Objects 2: %#", objects);
Console:
2015-02-09 21:06:30.845 SimpleTable[8373:1284663] Objects 2: (
"<na: 0x7ff3f8e40880, objectId: cOrjeAmwJh, localId: (null)> {\n away = Cav;\n date = \"04/19/2015\";\n dateTime = \"April 19, 2015, 16:00\";\n gNumber = 1;\n home = Bul;\n matup = \"Ca\";\n ro = \"Ro \";\n test = \"Test 2\";\n tv = T;\n}",

Answer 1

If you need the array, fetch it asynchronously in a method outside of the queryForTable method, get it like this:
PFQuery *query = [self queryForTable];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
// objects is the array for this table
NSMutableArray *array = [#[] mutableCopy];
for (PFObject *object in objects) {
NSLog(#"we got an object with dateTime = %#", [object objectForKey:#"dateTime"]);
[array addObject:[object objectForKey:#"dateTime"]];
// you can prove this with any of your keys: away, number, home, mat up, etc.
}
}
}];

Answer 2

if you just want to pass the objects into an array you can do so like this or a variation of:
- (PFQuery *)queryForTable
{
PFQuery *query = [PFQuery queryWithClassName:self.parseClassName];
self.someArray = [query findObjects];
return query;
}
