Grab NSString from Parse.com and paste it into UILabel

问题

I'd like to grab a NSString from the Parse.com and paste it into a Label in my iOS App.

Does anyone know how to do so ? I'm having massive problems with it :/

Thanks in advance

The counter-question is "Which NSString do you want to get"? I assume it's some property of a PFObject that you want to display, right? What makes this property so interesting?

Let's say you want to display the title of a Book whose author is Hemmingway.

First you want to find the object:

PFQuery *query = [PFQuery queryWithClassName:@"Book"];  // I want to find a book
[query whereKey:@"author" equalTo:@"Hemmingway"];       // authored by hemmingway
PFObject *book = [query findFirstObject];               // go get it!

Then you just read its properties with objectForKey

myLabel.text = [book objectForKey:@"title"];

Check out the iOS guides for more advanced questions. If you plan to display many properties of many PFObjects, you might want to check out the PFQueryTableViewController
