    <p>So I have been stuck for a couple of days on this extremely strange and annoying problem. So I have an app that I released to the ios app store and I have recently went back and added some extra features to the application. I didnt touch the core of the app just added things like twitter, facebook, in app purchases, and google admob (for the free version that is based off the full version). So here is where things go weird. I tested my update I made a adhoc release build and tested on my iphone 3gs, 4s, ipad 2 - no problems at all. I submitted to apple they approved the update and it was released. I updated the application and tried to run it and boom crashes right after the splash screen (again nothing here was changed). My project uses the cocos2dx framework (version cocos2d-2.0-x-2.0.4 @ Nov 02 2012) and I uses cocosbuilder (2.1). I looked at the log and it seemed to be an unalignment issue inside the CCBReader::readFloat() function. I found that there was a fix to this here: <a href="https://github.com/DarraghCoy/cocos2d-x/commit/34b31fd754778f815fcac108089e3fe015e2e2b9" rel="noreferrer">https://github.com/DarraghCoy/cocos2d-x/commit/34b31fd754778f815fcac108089e3fe015e2e2b9</a>. </p> <p>So I went ahead and modified my default case as well from this: float CCBReader::readFloat() { unsigned char type = this->readByte();</p> <pre><code> switch (type) { case kCCBFloat0: return 0; case kCCBFloat1: return 1; case kCCBFloatMinus1: return -1; case kCCBFloat05: return 0.5f; case kCCBFloatInteger: return (float)this-&gt;readInt(true); default: { /* using a memcpy since the compiler isn't * doing the float ptr math correctly on device. * TODO still applies in C++ ? */ float * pF = (float*)(this-&gt;mBytes + this-&gt;mCurrentByte); float f = 0; memcpy( &amp;f, pF, sizeof(float)); this-&gt;mCurrentByte += 4; return f; } } } </code></pre> <p>To this:</p> <pre><code> float CCBReader::readFloat() { unsigned char type = this-&gt;readByte(); switch (type) { case kCCBFloat0: return 0; case kCCBFloat1: return 1; case kCCBFloatMinus1: return -1; case kCCBFloat05: return 0.5f; case kCCBFloatInteger: return (float)this-&gt;readInt(true); default: { /* using a memcpy since the compiler isn't * doing the float ptr math correctly on device. * TODO still applies in C++ ? */ float * pF = (float*)(this-&gt;mBytes + this-&gt;mCurrentByte); float f = 0; memcpy((void*) &amp;f, (const void*) pF, sizeof(float)); this-&gt;mCurrentByte += sizeof(float); return f; } } } </code></pre> <p>Again testing a release build on devices no isses. I submitted this fix to apple and requested a expedited review so the application would run instead of crashing and it got apple approval within 1 day and was shipped out. I update to the new version launch and again its crashing.</p> <p>Here is a copy of the crash log:</p> <pre><code>Incident Identifier: DCFEA2A4-9707-4FF7-A4B7-26CF61B4A73F CrashReporter Key: b91e2f134184158618753244f837ff2ac5114f0d Hardware Model: iPhone4,1 Process: GAMEAPP [848] Path: /var/mobile/Applications/F860F02C-3D16-4995-A19F-CE036200209F/GAMEAPP.app/GAMEAPP Identifier: GAMEAPP Version: ???

Lastly how is it that apple approves the app yet it crashes right after the splash screen? If I can guess when the run the app it works and maybe it gets broken when it goes threw the "Processing for App Store" stage post app approval (not sure).</p> <p>Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
