POUITextField (sometimes) crashes the app while typing
text
Body
copied!<p>I am facing a problem with UITextField. It crashing the app (sometimes, not all the time) when I type in the UITextField. I suspect that this could be a memory issue as this happens only when I use the app continuously for 15 min. I hope I am correctly doing the memory management. And the app crashes particularly when I type something in the text field, not when doing some other action in the app. I am not sure what is causing the problem. </p> <p>I've googled and found discussions about some related crashes with UITextField, but they didn't help my problem.</p> <p>This is my crash log.</p> <pre><code>0 libobjc.A.dylib 0x3260a5b0 objc_msgSend + 16 1 CoreFoundation 0x32d8e034 _CFXNotificationPost + 1424 2 Foundation 0x37d93d8c -[NSNotificationCenter postNotificationName:object:userInfo:] + 68 3 Foundation 0x37d9784e -[NSNotificationCenter postNotificationName:object:] + 26 4 UIKit 0x35a9d268 -[UITextField fieldEditorDidChange:] + 284 5 UIKit 0x35a9cac0 -[UIFieldEditor webViewDidChange:] + 76 6 CoreFoundation 0x32d8e034 _CFXNotificationPost + 1424 7 Foundation 0x37d93d8c -[NSNotificationCenter postNotificationName:object:userInfo:] + 68 8 WebCore 0x33bee1e0 WebThreadPostNotification + 64 9 WebCore 0x33dc0d66 WebCore::Editor::appliedEditing(WTF::PassRefPtr<WebCore::CompositeEditCommand>) + 234 10 WebCore 0x33dc2efe WebCore::TypingCommand::insertTextRunWithoutNewlines(WTF::String const&, bool) + 130 11 WebCore 0x33dc2e18 WebCore::TypingCommandLineOperation::operator()(unsigned long, unsigned long, bool) const + 44 12 WebCore 0x33dc2cfa WebCore::TypingCommand::doApply() + 150 13 WebCore 0x33db84da WebCore::CompositeEditCommand::apply() + 118 14 WebCore 0x33dc2c38 WebCore::TextInsertionBaseCommand::applyTextInsertionCommand(WebCore::Frame*, WTF::PassRefPtr<WebCore::TextInsertionBaseCommand>, WebCore::VisibleSelection const&, WebCore::VisibleSelection const&) + 124 15 WebCore 0x33dc294a WebCore::TypingCommand::insertText(WebCore::Document*, WTF::String const&, WebCore::VisibleSelection const&, unsigned int, WebCore::TypingCommand::TextCompositionType) + 438 16 WebCore 0x33dc23da WebCore::Editor::insertTextWithoutSendingTextEvent(WTF::String const&, bool, WebCore::TextEvent*) + 382 17 WebCore 0x33dc2232 WebCore::Editor::handleTextEvent(WebCore::TextEvent*) + 274 18 WebCore 0x33dc2110 WebCore::EventHandler::defaultTextInputEventHandler(WebCore::TextEvent*) + 12 19 WebCore 0x33b8b7b8 WebCore::Node::defaultEventHandler(WebCore::Event*) + 244 20 WebCore 0x33b8b132 WebCore::EventDispatcher::dispatchEvent(WTF::PassRefPtr<WebCore::Event>) + 894 21 WebCore 0x33b8ad8a WebCore::EventDispatchMediator::dispatchEvent(WebCore::EventDispatcher*) const + 26 22 WebCore 0x33b8ad4e WebCore::EventDispatcher::dispatchEvent(WebCore::Node*, WTF::PassRefPtr<WebCore::EventDispatchMediator>) + 94 23 WebCore 0x33b8ac7e WebCore::Node::dispatchEvent(WTF::PassRefPtr<WebCore::Event>) + 30 24 WebCore 0x33d42d14 WebCore::EventTarget::dispatchEvent(WTF::PassRefPtr<WebCore::Event>, int&) + 68 25 WebCore 0x33dc1f26 WebCore::EventHandler::handleTextInputEvent(WTF::String const&, WebCore::Event*, WebCore::TextEventInputType) + 198 26 WebCore 0x33dc1e58 WebCore::Editor::insertText(WTF::String const&, WebCore::Event*) + 12 27 WebKit 0x3526a684 -[WebHTMLView(WebNSTextInputSupport) insertText:] + 304 28 WebCore 0x33db7206 -[WAKResponder tryToPerform:with:] + 58 29 WebKit 0x352905ea -[WebView(WebViewEditingActions) _performResponderOperation:with:] + 98 30 UIKit 0x35ad803c -[UIWebDocumentView insertText:] + 40 31 UIKit 0x35ad7ff4 -[UIKeyboardImpl insertText:] + 76 32 UIKit 0x35aa514c -[UIKeyboardImpl addInputString:fromVariantKey:] + 2816 33 UIKit 0x35aa3044 -[UIKeyboardImpl handleKeyEvent:] + 1636 34 UIKit 0x35aa28b2 -[UIKeyboardLayoutStar sendStringAction:forKey:isPopupVariant:] + 482 35 UIKit 0x35aa13a8 -[UIKeyboardLayoutStar touchUp:] + 3096 36 UIKit 0x35aa0732 -[UIKeyboardLayout touchesEnded:withEvent:] + 382 37 UIKit 0x359885f4 -[UIWindow _sendTouchesForEvent:] + 520 38 UIKit 0x35975804 -[UIApplication sendEvent:] + 376 39 UIKit 0x3597511e _UIApplicationHandleEvent + 6150 40 GraphicsServices 0x33aed5a0 _PurpleEventCallback + 588 41 CoreFoundation 0x32e12680 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 12 42 CoreFoundation 0x32e11ee4 __CFRunLoopDoSources0 + 208 43 CoreFoundation 0x32e10cb2 __CFRunLoopRun + 642 44 CoreFoundation 0x32d83eb8 CFRunLoopRunSpecific + 352 45 CoreFoundation 0x32d83d44 CFRunLoopRunInMode + 100 46 GraphicsServices 0x33aec2e6 GSEventRunModal + 70 47 UIKit 0x359c92fc UIApplicationMain + 1116 48 MyApp 0x00087578 0x1000 + 550264 49 MyApp 0x000030f4 0x1000 + 8436 </code></pre> <p>Any help?</p> <p>Thanks.</p> <p><strong>Edit:</strong> I have several text fields, in different view controllers, in my app. The app crashes randomly no matter which text text field I am typing in.
