ios - Can I get by by without ever using KVO? -

-

strange grammar, want ask if there cases if don't kvo (key value observation), app can't things/features?

thanks

key value observing offers functionality , behaviors unique , useful developer, in same cases offering glimpse @ values otherwise opaque.

for example, if want know precise duration of animation in cocoa otherwise black-box (for example, keyboard disclosure animation duration), kvo way know of establish that.

beyond that, it's useful pattern programming applications involve data (go figure). such, yet tool in developer's toolkit.

can without it? sure. there many tools can without, , 1 takes little bit of effort wrap head around initially. should make point of avoiding it? no, don't think - why you?

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
