所以我是相當新的反應本機和移動開發的一般情況下，這個錯誤不斷出現，失敗的測試文件是由Facebook提供的標準生成文件反應本地構建。RCTSharedApplication（）委託錯誤反應原生
這裏的測試：
- (void)testRendersWelcomeScreen
{
UIViewController *vc = [[[RCTSharedApplication() delegate] window] rootViewController];
NSDate *date = [NSDate dateWithTimeIntervalSinceNow:TIMEOUT_SECONDS];
BOOL foundElement = NO;
__block NSString *redboxError = nil;
RCTSetLogFunction(^(RCTLogLevel level, RCTLogSource source, NSString *fileName, NSNumber *lineNumber, NSString *message) {
if (level >= RCTLogLevelError) {
redboxError = message;
}
});
while ([date timeIntervalSinceNow] > 0 && !foundElement && !redboxError) {
[[NSRunLoop mainRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate dateWithTimeIntervalSinceNow:0.1]];
[[NSRunLoop mainRunLoop] runMode:NSRunLoopCommonModes beforeDate:[NSDate dateWithTimeIntervalSinceNow:0.1]];
foundElement = [self findSubviewInView:vc.view matching:^BOOL(UIView *view) {
if ([view.accessibilityLabel isEqualToString:TEXT_TO_LOOK_FOR]) {
return YES;
}
return NO;
}];
}
RCTSetLogFunction(RCTDefaultLogFunction);
XCTAssertNil(redboxError, @"RedBox error: %@", redboxError);
XCTAssertTrue(foundElement, @"Couldn't find element with text '%@' in %d seconds", TEXT_TO_LOOK_FOR, TIMEOUT_SECONDS);
}
這裏是錯誤：
redacted/ios/ProjectTests/Project.m:40:29: error: bad receiver type 'int'
UIViewController *vc = [[[RCTSharedApplication() delegate] window] rootViewController];
的應用程序似乎是實際編譯和工作的iOS模擬器，所以我真的不知道是什麼問題，明顯的答案可能只是刪除測試。不過，我對可能的原因感興趣，歡呼。
