vpn sonicwall iphone l2tp ipad
A client has a Sonicwall Pro 2040 running SonicOS 3.0, and they’d like to be able to use the L2TP VPN client from their iPads to connect to internal services (Citrix, etc). I’ve enabled the L2TP VPN server on the Sonicwall, made sure to set AES-128 for phase 2, and set up the configuration on a test iPad with the appropriate username, password, and pre-shared key. When I attempt to connect, I get some rather cryptic error messages in the log on the Sonicwall:2 03/29/2011 12:25:09.096 IKE Respo

iphone core-location
Is kCLErrorNetwork “fatal”, i.e. can location still be acquired or should we tell Core Location to stop updating the location?In iOS 3.0, Core Location added an error code, kCLErrorNetwork. It is described as a “general, network-related error”. Does this mean that neither the cell network nor Wi-Fi is available and Core Location can only use GPS? Or something else?

Ok, I only made a minor change to a project of mine in Xcode (I just added a new .h, .m, and .xib file, they’re very small), and now it won’t run and gives me this message:”fatal error: error writing to -: Broken pipe”WTF? So I removed all the changes and tried to run it again and it STILL gives me the error, what’s the deal?

I’m having the same problem that a couple of others have had with getting the correct behavior in a web app on an orientation change, and there doesn’t seem to be an obvious solution – I’ve seen this question asked a couple of times on Stack Overflow and no one’s yet been able to answer it.When I start the app in portrait mode, it works fine. Then I rotate into landscape and it’s scaled up. To get it to scale correctly for the landscape mode I have to double tap on something twice, first to zoo

iphone xcode terminal
Is there some way by which I can use Xcode only to organise my code and not display errors at the time of compilation? I want that the error messages and the output get displayed in the Terminal instead. I am a college student and am learning how to program in C. I really want the error messages to be displayed in the Terminal, as they are shown there in a fairly cryptic manner, instead of the user friendly manner which is there is in Xcode.

When using methods which return blocks they can be very convenient. However, when you have to string a few of them together it gets messy really quicklyfor instance, you have to call 4 URLs in succession:[remoteAPIWithURL:url1 success:^(int status){[remoteAPIWithURL:url2 success:^(int status){[remoteAPIWithURL:url3 success:^(int status){[remoteAPIWithURL:url2 success:^(int status){//succes!!!}];}];}]; }];So for every iteration I go one level deeper, and I don’t even handle errors in the nested

The problem is that when I compile it, it builds fine (no syntax problems), but there are no sockets being created. As you’ll notice I’ve commented out a lot of things in Server2.m and have isolated the problem to the very beginning when I create the struct for the listeningSocket. By the way, if

When something goes so horribly wrong that my app can’t continue and needs to exit, I want to pop up an alert box to the user, and then close the app when they tap the OK button. Sounds simple enough, right?But here’s the problem: my fatal error handler gets called by a 3rd party library (I don’t have their source code). I give them a pointer to my fatal error handler on initialization, and when they encounter a fatal error they simply call that routine and expect it to never return. If it r
