问题
I am trying to run the Street View example in the Google Maps SDK for iOS docs and am getting the following error:
`-[NSThread gtm_performBlock:]: unrecognized selector sent to instance 0x1d55d1f0. *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSThread gtm_performBlock:]: unrecognized selector sent to instance 0x1d55d1f0'. libc++abi.dylib: terminate called throwing an exception.
The strange thing is that I can get Street View to work in some projects and not others. I have tried both the Google 1.4.3 and 1.4.2 Frameworks and still get this error. Any idea what is causing it?

Choose your project, rather than a specific target, and open the Build Settings tab:
-In the Other Linker Flags section, add -ObjC. If these settings are not visible, change the filter in the Build Settings bar from Basic to All.
