问题描述

我想从Parse.com抓取NSString，并将其粘贴到我的iOS应用程序的标签中。

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

有没有人知道如何做？

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

提前感谢

推荐答案

反问题是你想要获得哪个NSString？我假设它是一个PFObject的一些属性，你想显示，对吧？
让这个属性如此有趣的是什么？

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?

假设您想显示图书 >

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

首先，您要找到对象：

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!

然后你只需读取它的属性 objectForKey

Then you just read its properties with objectForKey

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

查看 iOS指南，以了解更多高级问题。如果您计划显示许多PFObject的许多属性，您可能需要查看 PFQueryTableViewController

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
