OCMock转发到原始类方法

Question

OCMock为mock类方法提供了一个很好的语法，但类方法调用可以转发到真正的类对象吗？

self.connectionMock = [OCMockObject mockForClass:NSURLConnection.class];

[[[[self.connectionMock stub] andDo:^(NSInvocation *invocation) {
    NSURL *url = [invocation getArgumentAtIndexAsObject:2];
    NSLog(@"Passing through mock: %@", url);
} ] andForwardToRealObject] connectionWithRequest:OCMOCK_ANY delegate:OCMOCK_ANY];

问题是andForwardToRealObject仅适用于部分。我可以自己调整方法，但是有一种简单的方法可以让我使用OCMock调用原始的类方法吗？

Answer 1

子类OCMock并覆盖forwardingTargetForSelector：（SEL）选择器：

+(id)forwardingTargetForSelector:(SEL)selector
{
    Class yourClass = [classObject class];
    return yourClass;
}
