由 本秂侑毒 提交于 2019-12-10 15:10:58
问题 Skip all this info and skip to the update at the bottom... I have dealt with unrecognized selectors before, but I cannot figure out what is going on this time. The call stack is opaque and I can't find out where the problem is originating from. I have tried using symbolic and exception breakpoints. This code was working perfectly before..I come back to work on this program some more and am now running into this [UITableViewSectionElement numberOfSections]: unrecognized selector sent to

Unrecognized selector calling category method in static iOS library

由 独自空忆成欢 提交于 2019-12-09 08:39:32
问题 I am using some third party software to aid in writing an iPad application using Xcode 4.3.2. The software is open source and is usually set up so its code will be compiled along with whatever code the developer writes for the application. Because I was using the software in numerous places, I decided to build it as a static library for the iOS simulator. I was able to build the library, and convert one application to link to that library instead of compiling the original source code. However

问题 I'm new to SpriteKit and just published my first game. Now I would like to add banner ads to the game. However, I'm completely lost. Most tutorials tell you to simply call self.canDisplayBannerAds = YES; in the viewDidLoad method. I'm doing that, and I also imported iAD.h and linked the required binaries. However, everytime I start the game it crashes and gives me the following error: -[UIView presentScene:transition:]: unrecognized selector sent to instance 0x15e2dd00 Does anybody know a

NSURLSession dataTaskForRequest:completion: unrecognized selector sent to instance

由 独自空忆成欢 提交于 2019-12-04 22:11:59
When trying to create my own session object NSURLSession() and request an url I get an unrecognized selector exception but when I use the shared session NSURLSession.sharedSession() everything works fine. How come? var url = NSURL(string: "http:/www.google.com") if url != nil { //throws unrecognized selector when dataTaskWithURL is called let session=NSURLSession() session.dataTaskWithURL(url!) //works let sharedSession=NSURLSession.sharedSession() sharedSession.dataTaskWithURL(url!) } You have to init URLSession with a configuration: URLSession(configuration: .default) or use shared session
