从parse.com获取objectId

Question

So I am building an app that uses parse as a backend. I've written my own before but I figured I'll just save some time and use parse. I'm populating a table view with data from parse and that's fine. I want to grab the objectId from an dictionary built from an array from parse.

The output of my array is as follows:

<news_events:pdbIEvOteH:(null)> {\n    eventDescription = \"This is a test description.\";\n    eventMessage = \"This is a test message.\";\n    eventTitle = \"Free Wi-Fi Now Available!\";\n}

The object ID is pdbIEvOteH in the example above. I at first tried getting the id by using: NSString * objectId = [myDictionary objectForKey:@"objectId"]; But that returned null. I know it is not a problem with my dictionary because I can get other information. The problem is it looks like there is no key for objectId in the array above. As you can see it follows news_events .

I know you can get it with the PFObject but I'm not sure if I can populate a table with a PFObject .

So bottom line is how do I get the objectId .

Answer 1

In my didSelectRowAtIndexPath: method, I did the following:

PFObject *myObject = [parseArray objectAtIndex:indexPath.row];

NSString *objectId = [myObject objectId];

Answer 2

To get the Id of a particular PFObject.

In Swift:

var objectId = object.objectId

In Objective-C:

NSString *objectId = object.objectId;

Answer 3

"So bottom line is how do I get the objectId."

following is answer from 'Joe Blow' with actual/example code for ios.

i had similar issue. retrieving data with following code worked:

NSString *reporterOpinion = [NSString stringWithFormat:@"%@", [object objectForKey:@"reporterOpinion"]];

but trying to do objectForKey with objectId returned null:

NSString *objectId = [NSString stringWithFormat:@"%@", [object objectForKey:@"objectId]];

following 'Joe Blow' answer, the following code returned correct value for objectId:

NSString *objectId = object.objectId;
