OC plistファイルの読み込み

OCはplistファイルを読み込みます:

#import   int main (int argc, const char * argv[]) {      @autoreleasepool {                  NSArray * arr = [NSArray arrayWithContentsOfFile:@"/Users/zl201/Desktop/NSDictionaryHomework/ProvincesAndCities.plist"];         //                        for (NSDictionary *dic in arr) {             NSArray * cities = [dic objectForKey:@"Cities"];                          for (NSDictionary * city in cities) {                 NSString * cityName = [city objectForKey:@"city"];                 NSString * lat = [city objectForKey:@"lat"];                 NSString * lon = [city objectForKey:@"lon"];                 NSLog(@"%@ lat = %@ lon = %@",cityName,lat,lon);             }         }      }     return 0; }
