@ try/@ catch不会捕获异常

应在Xcode 6.4中修复After upgrading Xcode from 6.0 to 6.3, I noticed my automated tests started failing.2015-04-14 18:56:50.625 xctest[48304:517820] *** Terminating app due to uncaught exception 'foo', reason: 'bar'*** First throw call stack:( 0 CoreFoundation 0x0084a746 __exceptionPreprocess + 182 1 libobjc.A.dylib 0x004d3a97 objc_exception_throw + 44 2 CoreFoundation 0x0084a66d +[NSException raise:format:] + 141 3 TestTests 0x03e6dbdc -[TestTest test] + 810 4 CoreFoundation 0x0072b84d __invoking___ + 29 5 CoreFoundation 0x0072b6f8 -[NSInvocation invoke] + 360 6 XCTest 0x20108975 -[XCTestCase invokeTest] + 320 7 XCTest 0x20108baa -[XCTestCase performTest:] + 175 8 XCTest 0x20114122 -[XCTest run] + 314 9 XCTest 0x20107598 -[XCTestSuite performTest:] + 406 10 XCTest 0x20114122 -[XCTest run] + 314 11 XCTest 0x20107598 -[XCTestSuite performTest:] + 406 12 XCTest 0x20114122 -[XCTest run] + 314 13 XCTest 0x20107598 -[XCTestSuite performTest:] + 406 14 XCTest 0x20114122 -[XCTest run] + 314 15 XCTest 0x20103df2 __25-[XCTestDriver _runSuite]_block_invoke + 61 16 XCTest 0x20110c42 -[XCTestObservationCenter _observeTestExecutionForBlock:] + 184 17 XCTest 0x20103d16 -[XCTestDriver _runSuite] + 285 18 XCTest 0x20104961 -[XCTestDriver _checkForTestManager] + 272 19 XCTest 0x20104c79 -[XCTestDriver runTestSuite:completionHandler:] + 376 20 XCTest 0x2011772c +[XCTestProbe runTests:] + 216 21 libobjc.A.dylib 0x004e967e +[NSObject performSelector:withObject:] + 70 22 xctest 0x0000823a xctest + 4666 23 xctest 0x000084b0 xctest + 5296 24 xctest 0x00008591 xctest + 5521 25 xctest 0x00007e3d xctest + 3645 26 libdyld.dylib 0x019d4ac9 start + 1)libc++abi.dylib: terminating with uncaught exception of type NSExceptionAfter further investigation it appears exceptions are now uncatchable. Both these snippets would cause this error.XCTAssertThrows([NSException raise:@"foo" format:@"bar"]);and @try { [NSException raise:@"foo" format:@"bar"];}@catch (NSException *ex) { NSLog(@"caught");}After a VCS force clean sync and rebuild everything looked fine, but then the same failure started in a couple of builds time. Does anyone have any ideas? 解决方案 Following the developer forums, this appears to be a bug or oversight in the developer tools that introduced an incompatibility with binaries built with older versions of the tools.Should be fixed in Xcode 6.4 这篇关于@ try/@ catch不会捕获异常的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
