带有代码块的存根方法作为OCMock的参数 [英] stub method with block of code as parameter with OCMock

问题描述

有没有办法使用存根方法，它将块作为参数？例如mehod：

Is there a way to stub method, that takes block as it's parameter? For example mehod:

- (void)reverseGeocodeLocation:(CLLocation *)location completionHandler:(CLGeocodeCompletionHandler)completionHandler;

推荐答案

是的。最简单的方法是接受任何东西：

Yes. The easiest way would be to accept anything:

id mockGeocoder = [OCMockObject mockForClass:[CLGeocoder class]];
[[mockGeocoder stub] reverseGeocodeLocation:[OCMOCK_ANY] completionHandler:[OCMOCK_ANY]];

如果要验证传入的特定块，它会变得有点棘手。一个选项是使您的完成处理程序成为您的类的属性，在初始化类时初始化它，并让测试直接匹配它：

It gets a bit trickier if you want to verify a particular block is passed in. One option is to make your completion handler a property of your class, initialize it when you initialize your class, and have the test match it directly:

// in your class
@property(copy)CLGeocodeCompletionHandler completionHandler;

// in your class's init method
self.completionHandler = ^(NSArray *placemark, NSError *error) {
    //
}

// using the completion handler
[geocoder reverseGeocodeLocation:location completionHandler:self.completionHandler];

// the test
id mockGeocoder = [OCMockObject mockForClass:[CLGeocoder class]];
[[mockGeocoder stub] reverseGeocodeLocation:[OCMOCK_ANY] completionHandler:yourClass.completionHandler];
