我在一个方法中有这段代码:
- (NetworkOperation *)runOperationWithPath:(NSString *)path
params:(NSDictionary *)params
httpMethod:(NSString *)httpMethod
completionHandler:(DictionaryCompletionHandler)completionHandler;
{
NetworkOperation *op = (NetworkOperation *)[self operationWithPath:path
params:[params mutableCopy]
httpMethod:httpMethod
ssl:YES];
[op addCompletionHandler:^(NetworkOperation *completedOperation) {
NSData *responseData = [completedOperation responseData];
NSError *error;
NSDictionary *returnDict = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:&error];
if(error == nil && !self.timedOut) {
completionHandler(returnDict, nil);
} else {
completionHandler(nil, error);
}
} errorHandler:^(NetworkOperation *completedOperation, NSError *error) {
//Manage error
}];
[self enqueueOperation:op];
return op;
}
我正在为它创建单元测试，我发现了这种奇怪的行为。在单元测试中，我使用 OHHTTPStubs 来 stub 网络响应。单元测试的代码在这里
- (void)testThatTheRequestRunAndCallsTheCompletationBlock; {
//Here i have the setup of OHHTTPStubs to stub the responses.
__block BOOL called = NO;
[self.restClient runOperationWithPath:@"Rest/clientTest" params:nil httpMethod:@"POST" authenticationEngine:nil completionHandler:^(NSDictionary *result, NSError *error) {
called = YES;
}];
while (CFRunLoopRunInMode(kCFRunLoopDefaultMode, 0, true) && !blockFinished)
STAssertTrue(called, @"The completation block should be called");
}
如果我运行单个单元测试一切正常，如果我运行整套单元测试应用程序崩溃调用 completationHandler 为 nil。 我不明白，因为在第一种情况下(单次运行)嵌套 block 被正确复制，当我运行整个测试套件时嵌套 block 没有被容器 block 正确捕获。
我尝试删除 OHHTTPStubs 并阻止等待代码，但没有任何变化。关于如何调试它的一些想法？
最佳答案
错别字:
- (void)testThatTheRequestRunAndCallsTheCompletationBlock; {

关于ios - block 无法导入嵌套 block ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19299812/
