ios6

new iOS 6 feature is, that you can debug html and javascript running on device or simulator in desktop safari. I suppose, that this feature is based on Webkit Remote Debugging Protocol . How can I connect to webkit running on iPhone without desktop Safari? I can do this for mobile Chrome running on Android using websockets, but how can I do that for iOS devices? The ios-webkit-debug-proxy project (from Google!) does this. You want to look at this code https://github.com/leftlogic/remote-debug/tree/master/safari - although it fails when it actually comes to RPC calls that use __rpc

How to track usage of data sent and received through my app? I just want to record bytes sent and received when my app is running. If I can get separate info for Wifi and Cellular network then it would be great but its not a priority. I know how to find total usage of device - https://stackoverflow.com/a/8014012/427969 Also, I know I can use Instruments to collect network activity data but I want to record this data in my app so need a programmatic way to do this. I tried to search this but all I find is device's network usage and not a particular app's usage. The following is the screenshot

I've been testing my app in the 4-inch and 3.5-inch iPhone simulators, and when bringing up a keyboard with a UITextField in the 4-inch simulator in landscape mode, it's squished up to the side. It looks like a normal 3.5-inch keyboard: Am I missing something telling it to stretch properly? Please note - I don't have access to an actual iPhone 5 device to test on. Any help would be appreciated. Maybe your simulator is set to the 4-inch model but is running iOS5--this setup is possible in iOS Simulator but doesn't exist in the wild. 来源： https://stackoverflow.com/questions/12797419/iphone-5

Since updating to iOS 6 I have this weirdest bug when trying to make an UITextField or UITextView firstResponder. ...it doesn't work. I am not able to select the field or view and bring up the keyboard, nor is there a cursor or anything. The weirdest thing is that it is only not working for SOME fields, other ones in different viewcontrollers work without trouble. I have: [self.window makeKeyAndVisible]; self.window.rootViewController = self.viewController; in my appDelegate. It worked and still works without problems with iOS 5. Any ideas on what it could be? Thanks! I found out what was

I am trying to use native (iOS 6-7x) libraries to authorize a user with Facebook from my app. I would like to pass the auth token to my server when login is successful. The code below works fine except when the user has not set up their Facebook account in the OS. I get the following error in this case: Error Domain=com.apple.accounts Code=6 "The operation couldn’t be completed.
