iphone - 从不兼容的指针类型传递 ObjectForKey 的参数

Question

大家好!当我构建这个时，我在 objectForKey 上收到警告...警告说； “从不兼容的指针类型传递‘objectForKey:’的参数 1”有谁知道如何解决这个问题吗？

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark{
    NSString *streetAddress = [NSString stringWithFormat:@"%@", 
                                 [placemark.addressDictionary objectForKey:kABPersonAddressStreetKey]]; 

                               mapView.userLocation.subtitle = streetAddress;
}

提前致谢!

Answer 1

转换参数以消除警告。

[placemark.addressDictionary objectForKey:(NSString *)kABPersonAddressStreetKey]
