Crash: [UIWindow selectedTextRange]: unrecognized selector

[philippelatulippe]

I get a crash when I first load the viewer in my browser:

Hierarchy Viewer[6532:6307] REQUEST HTTP INIT LINE: GET /snapshot?nocache=1353964561487 HTTP/1.1
Hierarchy Viewer[6532:c07] -[UIWindow selectedTextRange]: unrecognized selector sent to instance 0xf36b030

Things I have done:

• Tried versions 1.4.5 and 1.4.6
• added -ObjC -all_load to my linker flags. (I actually did -ObjC -force_load <path/to/lib.a>, which should do the same thing.)
• Removed a library that had JSONKit.m

Running on:

• iPad 5.1 Simulator
• Mac OS X 10.8.2
• XCode 4.5.2
• llvm 4.1

This is a fairly large project with a great deal of static libraries, so if this is not an obvious crash, I can try chopping thing off the project to see if it works.

It would be great if releases were tagged, that way I could try to debug this without having to build the library myself.

Ah, it wasn't a crash. I had a breakpoint set for all exceptions. So the bug is that the library sends selectedTextRange to all objects in the hierarchy without first checking if it responds to it.

Thanks mate, I had the same problem. Like you said, removing "all exceptions" breakpoint fix it.

I'm having the same problem here, absolutely no breakpoints set, yet it's crashing on me. I'm wondering if it's due to iOS6. I tried w/ older Xcode and 5.1 SDK and had a completely different crash.

[hunanboy]

I ran into same problem. Andrew you are probably right. I just updated Xcode to iOS 6.1 SDK and had this problem. When I used view hierarchy a couple of months ago, it works fine as long as I turn breakpoint off.

I have this problem too . any method to solve it without have to turn the breakpoint off ?
