Pintrest sharing crash on ios

Question

I want to share a message with Pintrest (i.e. I want to connect to my application). I used my SDK using Cocoa Pod. I can sometimes bind (sometimes), but sometimes when they are fixed, the application accidentally crashes and gets nothing in the crash log.

Can someone tell me what is going wrong? I am adding a piece of code that I used ... I used this link to install the SDK and followed this link. https://github.com/pinterest/ios-pdk

-(IBAction)pintrestButtonTapped

    @try
    {
        [PDKClient configureSharedInstanceWithAppId:@"4841203782190640720"];

                                                                  PDKClientReadPrivatePermissions,
