Connect 3rd Device using GameKit

阅读更多关于 Connect 3rd Device using GameKit

问题 I am using GameKit on a basic level right now. I am able to connect two devices and send messages between them. I have 3 devices, we'll call them device A, B and C. I am able to connect A to B, A to C, and B to C, as individual setups. If I connect A to B, then attempt to connect B to C, Device C will show that Device B is available, but device B continues to spin and say "Looking for available iPod, iPhones..." In peerPickerController:sessionForConnectionType: , when I am attempting to

阅读更多关于 what slows down GKSession's network throughput?

问题 I implemented an app that does real time broadcasting of music from one iphone to another based on Ray Wenderlich's tutorial about GKSession and Matt Ghallagher's tutorial on audio streaming. Everything worked perfectly.. until we've decided to replace the poker game UI with that of our own. The result is that suddenly the networking throughput drops dramatically. Below is a profiler snap shot of the server Here is a snapshot of the client of the original app and here is a snapshot of the

Connection trouble with GKPeerPickerController

阅读更多关于 Connection trouble with GKPeerPickerController

问题 I am working on an iOS game with GKSession and GKPeerPickerController. I am finding that the process of connecting two iOS devices is slow and unreliable, even if they are right next to each other. Let's call my devices "device A" and "device B." Here is what typically happens: On each device, I hit my app's connect button. Each device then shows the "iPads, iPhones, or iPod touches" window. Usually pretty quickly, the two devices each notice that the other exists. I then tell one of the

问题 I'm trying to create an app that transfers data between 2+ phones using GKSession. Thing is there are two options: First: using the GKPeerPicker.. However here I get stuck at the point where I have to implement my own WIFI interface.. apple provides no instructions on how to do that: - (void)peerPickerController:(GKPeerPickerController *)picker didSelectConnectionType: (GKPeerPickerConnectionType)type { if (type == GKPeerPickerConnectionTypeOnline) { picker.delegate = nil; [picker dismiss];

GKSession peer disconnect causes other peers to appear disconnected

阅读更多关于 GKSession peer disconnect causes other peers to appear disconnected

My app uses GKSession with GKSessionModePeer. It has to handle peers arbitrarily connecting and disconnecting because this is a long running app and users should be able to go to background and come back later. This works fine most of the time. But sometimes, when a peer disconnects, other devices get notified with didChangeState:GKPeerStateDisconnected not only for the device that really disconnected but also for other devices that are actually still connected. I can reproduce this behavior with the code below and 4 devices (all on iOS 5). When everything goes as expected, when device A quits
