Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

[Crash] Using Native iOS UIViewController+UIWebView

this Example Project GitHub src : https://github.com/sangpan/UENativeiOSCrashReport

replay crash video : https://youtu.be/btWuCZTgITM?t=1m12s

using Engine 4.11, 4.12 ...

testdevice : iphone 5s 9.3.2

Just Simple Code. Create UIViewController. and Add UIWebView to that UIViewController.

 MyWebViewController * myVC1;
 myVC1 = [[MyWebViewController alloc] init];
     dispatch_async(dispatch_get_main_queue(), ^{
 //use presentViewController
     [myVC1.view addSubview:_webView];

then run with some website like www.google.com.. input something with iOS virtual Keyboard, click link, click link, drag webpage etc ..

And suddenly crash occured from engine source ( [AutoreleasePool release]; ).

I don't use any memory free, drain, dealloc code.

Can't find exactly crash condition. (Engine's Memory management Issue??)

I try to use [[IOSAppDelegate GetDelegate] ToggleSuspend:true]; for avoiding this crash problem.

But it cause some side effect. (sometime Suspend absorb Home Button event).

I want to native iOS UIViewController+UIWebView.

Add Test Codnition (Update Git Source Code.)

  1. Create UIViewController (MyInputViewController)

  2. Add subview UITextField to UIViewController.

  3. Run. show and hide Virtual keyboard

  4. crash will occured.

If using new UIViewcontroller with presentViewController:animated:completion: , I think that UE can't manage UIKit (like virtual keyboard memory management?.. uipickerview ..?).
