从不兼容的指针类型传递ObjectForKey的参数

Question

嘿大家好！ 当我构建这个时，我会在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？

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

                               mapView.userLocation.subtitle = streetAddress;
}

提前谢谢！

施放参数以杀死警告。

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