Parse: Query to change labels text - objective-c

Question

I can currently query a parse class, but can't figure out how to change a labels text if the returned values match the query. I am relatively new to objective C and Parse so my knowledge on the subject is little. My query looks like this (with the text of what i'm trying to achieve underneath).
PFQuery *FTQ0 = [PFQuery queryWithClassName:#"Class1"];
[FTQ0 whereKey:#"Location" equalTo:#"The Shop"];
//Label.text = query (object?)
Thanks in advance.

Answer 1

Here is a solution. You have to be careful though, because there might be many objects that have key Location and equal to The Shop. This is why parse is returning an array of objects. In this case, I pick the first object in the array and display it.
PFQuery *query = [PFQuery queryWithClassName:#"Class1"];
[query whereKey:#"Location" equalTo:#"The Shop"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
Label.text = [NSString stringWithFormat:#"%#", [[objects firstObject] objectForKey:#"WHATEVER YOU WANT TO DISPLAY EX. NAME, LOCATION..."]]
} else {
// Log details of the failure
NSLog(#"Error: %# %#", error, [error userInfo]);
}
}];

Something like this :
PFQuery *query = [PFQuery queryWithClassName:#"Class1"];
[query whereKey:#"Location" equalTo:#"The Shop"];
[query getFirstObjectInBackgroundWithBlock:^(PFObject *object, NSError *error) {
if (!error && object) {
// Do your stuff
Label.text = [[object objectForKey:#"YOUR KEY"] stringValue];
} else {
// Error or null object
}
}];
In this example the query return only the first object.
