xcode - iOS mapView animatesDrop -

-

in mapview, have bool animatesdrop annotations set no. because when mapview annotations plotted during viewwillappear, don't when them animated. however, have refresh button used re-plot annotations , them animated (drop) when pushed. there way of accomplishing this? thanks.

-(mkannotationview *)mapview:(mkmapview *)mapview viewforannotation:(id<mkannotation>)annotation {      if ([annotation iskindofclass:[mkuserlocation class]]) {          return nil;     }      mypin = [[mkpinannotationview alloc] initwithannotation:annotation reuseidentifier:@"current"];      uibutton *calloutbutton = [uibutton buttonwithtype:uibuttontypedetaildisclosure];      uibutton *directionsbutton = [uibutton buttonwithtype:uibuttontypecustom];     directionsbutton.frame = cgrectmake(0, 0, 23, 23);     [directionsbutton setbackgroundimage:[uiimage imagenamed:@"directions.png"] forstate:uicontrolstatenormal];      mypin.leftcalloutaccessoryview = directionsbutton;     mypin.rightcalloutaccessoryview = calloutbutton;     mypin.draggable = no;     mypin.highlighted = no;     mypin.animatesdrop= yes;     mypin.canshowcallout = yes;      return mypin; }

"hard ball" approach establish boolean property set false in viewwillappear, set true in button's action. set mypin.animatesdrop property in viewforannotation. don't know of "elegant" solution.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
