objective c - MKMapView pin animation and annotation -

-

i'm using google places api find restaurants nearby (based on current location using core location manager); currently, i'm able drop pins. use searchbarsearchbuttonclicked method, , inside of dispatch_async block, call method parse through serialized data , attribute values properties of pin class (class mkannotation). i'd animate pin drops, , display annotations...for reason had them working before won't show when click on pins.

view controller.h

@interface myviewcontroller : uiviewcontroller <cllocationmanagerdelegate, mkmapviewdelegate, uisearchbardelegate,nsurlsessiondelegate> {      cllocationmanager *locationmanager;  }  @property (strong, nonatomic) mkmapview *mapview;  @property (strong, nonatomic) uisearchbar *searchbar;  @property (strong, nonatomic) uiimageview *logo;  @property (strong, nonatomic) uitoolbar *toolbar;  @property (strong, nonatomic) nsstring *places;  @end

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
