ios - XIB popover display -

-

i seem having trouble making popover xib display when app loaded. here have in viewdidload.i sorry, new looking tutorials , ran problem app crashes. error log "terminating app due uncaught exception 'nsexception', reason: 'could not load nib in bundle:" "(loaded)' name 'search''

     viewcontroller* viewcontroller2 = [[viewcontroller alloc] initwithnibname:@"search" bundle:nil]; self.popovercontroller = [[uipopovercontroller alloc] initwithcontentviewcontroller:viewcontroller2];  _popovercontroller.popovercontentsize = cgsizemake(350,100);

look @ this.

it says nib 'search' not exist in builded app. either xib not named "search.xib" or xib not included project. can check looking .app-directory on phone or simulator.

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
