Review comment (suggestion):
Now the `MapKit` component can only dependent the public header from `SDWebImage`, not the private header. So this can not use `@weakify` macro

Code after:
    [self sd_setImageWithURL:url placeholderImage:placeholder options:options context:context progress:nil completed:nil];
}
