"There was an internal API error." while running an app on any iPhone/iPod-touch device_问答_开发者

I am in the process of submitting an iPhone app to the App Store. While making the final touches to the app I was in the process of compiling and running the app on my iPhone when I got this message:

There was an internal API error.

The console had this to say:

25/08/2010 10:10:54 Xcode[3556] Failed willExecute: Error Domain=com.apple.platform.iphoneos Code=0 UserInfo=0x2011adec0 "There was an internal API error." -- {
    NSLocalizedDescription = "There was an internal API error.";
    NSLocalizedFailureReason = "";
    NSLocalizedRecoverySuggestion = "";
}

The problem is specific to this project, others projects don't suffer the same problem开发者_Python百科. The same problem exhibits when moved to another machine, or another mobile device is swapped in.

I should be most grateful for any hints or ideas on the subject.

I had the same problem on Xcode 4.5 beta 4 when I've tried to run an app which was already installed on my iOS device. You could try to remove your app from device and make sure you are using Developer profile for signing.

Aha! Thank heavens for subversion. Through comparison with a working version I found out that an offending 'UIRequiredDeviceCapabilities' in my info.plist was at fault. A little figure digging showed it had to be an Array or Dictionary, and not a string as was my case. Setting it thusly ...

<key>UIRequiredDeviceCapabilities</key>
<array>
    <string>still-camera</string>
</array>

.. solved the problem.

@Toastor, this happened during the deployment process, even before the app went down the wire to the device.

my problem was using a distribution profile, forgot to change back to a developer profile and that was what caused the internal api error. hope it helps someone

I had the same issue. My case was an iPhone that was used for the first time on the laptop. I fixed it by opening the project in XCode with the iPhone plugged in. Xcode will then say "Processing symbol files". When finished, deploying on iPhone worked from within the QT Creator.

States that you need to change project name to an english name

I had the same problem, and it worked when I removed the app from my phone and Built and Run again. I'm guessing you might have tested a build from a different branch and then tried to switch back to yours.

I deal with same problem, but because of manually deleting "Application/Myapp" folder. I copied back the files and uninstall it. Then I tried to run it using Xcode. Now every things is OK.

I had this problem as well - the problem turned out to be in the entitlements. I had get-task-allow set to NO instead of to YES. Once this was set properly everything worked again.

1.Check your project's Info.plis document code (not table list--open as source code ).There may be configuration error.

2.I solve the problem by this way : Create a new project , Compare the Info.plis code, and fix the old one .

that works for me ..

You need to register the device from Xcode.

General -> Signing -> Register.

I had it when removing a day extension / widget and forgetting to remove the Embed App Extensions item where the extesion is listed as plug-in

I had the same issue when I tried running my project from a different Mac than it was created.

My issue was in the info.plist file. We were only able to figure it out after recreating the project from scratch and adding one file at a time and trying to debug it.

Replaced the following the info file:

CFBundleDevelopmentRegion Language en name with $(DEVELOPMENT_LANGUAGE)
CFBundleExecutable Name with $(EXECUTABLE_NAME)
CFBundleName Name with placeholder $(PRODUCT_NAME)

Remove

CFBundleSignature

I turned off my iPhone and when I turned it back on, it worked!

After I tried everything, I noticed that it worked on another iPhone, so I tried everything on the device where it did not work. So unfortunate that this unexpected trick had to be the solution for me.

Same error when XCode+MonkeyDev to debug YouTube ipa.

Finally fixed by:

try more
and XCode -> Clean Build Folder

As explained in another post with the same problem, it sounds crazy but you can also not use the Beta version of Xcode 4. However, you must keep it in your left hand to authorize your iPhone to compile with the non Beta version (don't ask me why, it works).

If you run your app with Xcode 4.5 preview & iOS 6 Beta 4, the second time you run your app on the device, you'll get the internal API error.

In theory, you cannot use Xcode 4.4 to compile on your iOS6 Beta 4 iPhone.

But...

It seems that, if you launch Xcode 4.5 Preview, connect your iPhone (so it is recognized), run the application on it (even if you get the error), quit Xcode 4.5, launch Xcode 4.4 and .. tadaaaa... your iPhone is now recognized as an authorized device to compile on...

And of course, Xcode 4.4 doesn't generate the API error...
