推荐答案

是.

名为 calculateETAWithCompletionHandler:的 MKDirections 方法可能很容易忽略.

The MKDirections method named calculateETAWithCompletionHandler: can just be a bit easy to overlook, though.

一个实现可能如下所示:

An implementation could look as follows:

MKDirections *yourDirections = ...;

[yourDirections calculateETAWithCompletionHandler:^(MKETAResponse *response, NSError *error)
{
     NSTimeInterval estimatedTravelTimeInSeconds = response.expectedTravelTime;
     ...
}];
