Parse.com error 'Method not allowed when Pinni

问题:

I am currently using 1.6.1 via CocoaPods (= latest)

In my swift project I enable the localdatastore and then set the parse application id. After that, I load a storyboard which is a PFQueryTableViewController subclass. Really nothing special there. But it still crashes. It seems to crash in Parse internally on [PFQuery setCachePolicy:]

What could be wrong? How do I make offline functionality working?

回答1:

You cannot use the old query caching policies when pinning is enabled.

See here: PFQuery Class Reference - cachePolicy

回答2:

I've made an example project to demo the problem to Parse.com (see the bug: https://developers.facebook.com/bugs/1544122569192939/).

The response that I got from Parse was that the ParseUI framework from cocoapods is known to have this problem.

They suggested I get ParseUI from https://parse.com/docs/downloads

I'll try and see if that fixes the problem with my PFQueryTableViewController

Edit: I've added the framework manually and took it out of the Podfile. The crash now no longer occurs. So the bug is in the ParseUI cocoapod like parse told me on developers.facebook.com

回答3:

I also faced the same problem.
I commented below line from classes which extends PFQueryTableViewController & it worked for me.

if ([self.objects count] == 0) {
    query.cachePolicy = kPFCachePolicyCacheThenNetworkd;
}

回答4:

I had got the exact stack trace thrown when I was trying out Parse. But then figured out that I had included this line of code in my app delegate.

Objective-C

[Parse enableLocalDatastore];

I removed this code and it worked like a charm.

Swift

Remove:

Parse.enableLocalDatastore()

回答5:

//
//  AppDelegate.swift

import UIKit
import Parse
import Bolts


@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
    Parse.enableLocalDatastore()
    Parse.setApplicationId("#######", clientKey: "#####")
    PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
    return true
}

setApplicationID inside App Delegate instead of Controller solves the problem for me.

回答6:

you can try this code in swift.

if [self.objects].count == 0 {

        query?.cachePolicy = PFCachePolicy.CacheThenNetwork

    }

回答7:

I added 'import Bolts' below:

import UIKit

import Parse

As shown in the screen shot.

This fixed the issue for me.
