How do you implement an MPVolumeView?

阅读更多关于 How do you implement an MPVolumeView?

问题 I want the user to be able to change the system volume with a slider, and I realized the only way to do this is with an MPVolumeView. But I can't find any example code for it, and every method I try to implement won't show up. So what is the easiest and correct, working way of implementing a MPVolumeView? 回答1: Place it as a regular slider, then use the inspector to set the class to MPVolumeView . It'll still be shown as a regular slider in IB, but at runtime, it will be an instance of

How do you set the hardware volume in an iPhone app?

阅读更多关于 How do you set the hardware volume in an iPhone app?

Some iPhone applications, such as Pandora seem to directly manipulate the hardware volume and respond to physical volume button. How is this done? AudioSessionServices allows you to get the current hardware output volume with the kAudioSessionProperty_CurrentHardwareOutputVolume property, but it is (allegedly) read-only. They use the MPVolumeView, simple add it and it's makes the rest when the user touch it. Note: Doesn't work in iPhone Simulator. I think the release note also mentioned do not use it direct in Interface Builder. MPVolumeView *volumeView = [[MPVolumeView alloc] initWithFrame

kubernetes persistent volume accessmode

阅读更多关于 kubernetes persistent volume accessmode

问题 It seems that Kubernetes supports 3 kinds of access mode for persistent volume: ReadWriteOnce , ReadOnlyMany , ReadWriteMany . I'm really curious about the scheduler strategy for a pod which uses the ReadWriteOnce mode volume. For example, I created an RC which have pod num=2, I guess the two pods will be scheduled into the same host because they use the volume that has ReadWriteOnce mode? I really want to know the source code of this part. 回答1: If a pod mounts a volume with ReadWriteOnce

iPhone: How to play local notification sound loud independent of volume setting?

阅读更多关于 iPhone: How to play local notification sound loud independent of volume setting?

问题 The FoneHome iPhone app has a feature where you can play a sound as part of a local notification. That sound is loud regardless of what the iPhone's volume level is set at. How is it possible to get a local notification (or push) to play an audio alert that is loud independent of what the current iPhone volume level is? I tried just setting the soundName to a WAV file but it plays at whatever the current volume is, and I see no options to set it otherwise. 回答1: Try using the following code

How to mute the sound of my application?

阅读更多关于 How to mute the sound of my application?

I have an application which has sound. I have a global property to mute the sound. The problem is, there's so many different things which can make sound, I would hate to iterate through different class types and mute/unmute their sound. Instead, I'm looking for a way to mute the sound on a global application level. I don't mean muting the entire system volume either. One scenario: In Windows 7, you can open the Volume Mixer and adjust the volume of individual applications. While I don't intend to change this actual particular value (as I know it's Windows 7 specific), I would like to change

I have this code: Synthesizer synthesizer = MidiSystem.getSynthesizer(); synthesizer.open(); Instrument[] instrument = synthesizer.getDefaultSoundbank().getInstruments(); synthesizer.loadInstrument(instrument[29]); MidiChannel[] channels = synthesizer.getChannels(); MidiChannel channel = channels[1]; channel.programChange(29); channel.noteOn(noteNumber, 127); Teszthang.sleep(2000); channel.noteOff(noteNumber); so this is an example, to play a sound in max volume (127) for 2 seconds. but i want to control the channel's volume, like after 2 seconds, the volume fade out in an another 2 seconds.
