问题
I'm using a UIWebView in my app, and everything works fine in iOS5 and 6. But on iOS7 the UIWebView can't load the page requested (an html from internet) and start an infinite loop with this error every 10 secs:
void SendDelegateMessage(NSInvocation *): delegate (webView:decidePolicyForNavigationAction:request:frame:decisionListener:) failed to return after waiting 10 seconds. main run loop mode: kCFRunLoopDefaultMode
The webview loadrequest is located in viewDidAppear.
I found no documentation for this bug for iOS. The method decidePolicyForNavigationAction seems to be used only in WebKit for MacOS.. and not for iOS.
Same problem both on device and on simulator. I saw similar topics on stackoverflow, but noone report a working solution :/
Thanks for your help.
回答1:
Try to download new xCode version 5.0.1
This issue is fixed in version 5.0.1
Also, clean all the builds from the path ~/Library/Developer/Xcode/DerivedData/~
Build after clean. Everything works fine.
Let me know if the issue still persist.

Problem solved:
My problem was related to a library linked in the project: pspdfkit v2.x on iOS7.
Initializing the uiwebview before pspdfkit (even without presenting it) solved my problem.
