我正在尝试在类文件的顶部设置一个变量,以便我可以在几行之后使用它。我遇到的问题是Instance member 'streamWidth' cannot be used on type 'BroadcastViewController'
。所以我认为这是因为我不能在主类中引用这个变量,我必须在函数中使用它。现在如果是这种情况,有没有办法解决这个问题?
class BroadcastViewController: UIViewController, VCSessionDelegate {
@IBOutlet weak var previewView: UIView!
@IBOutlet weak var btnConnect: UIButton!
var streamWidth:Int = Int(5)
var session:VCSimpleSession = VCSimpleSession(videoSize: CGSize(width: streamWidth, height: 720), frameRate: 30, bitrate: 1000000, useInterfaceOrientation: false)
override func viewDidLoad() {
super.viewDidLoad()
previewView.addSubview(session.previewView)
session.previewView.frame = previewView.bounds
session.delegate = self
}
deinit {
btnConnect = nil
previewView = nil
session.delegate = nil;
}
@IBAction func btnConnectTouch(sender: AnyObject) {
switch session.rtmpSessionState {
case .None, .PreviewStarted, .Ended, .Error:
session.startRtmpSessionWithURL("rtmp://east-us.livewx.tv/live", andStreamKey: "fb4843e86976e37" + "?key=" + "e5615d9b171384a0613f")
default:
session.endRtmpSession()
break
}
func connectionStatusChanged(sessionState: VCSessionState) {
switch session.rtmpSessionState {
case .Starting:
btnConnect.setTitle("Connecting", forState: .Normal)
case .Started:
btnConnect.setTitle("Disconnect", forState: .Normal)
default:
btnConnect.setTitle("Connect", forState: .Normal)
}
}
// more functions left out for length reasoning
}
因此,其中一些函数,如deinit
、btnConnectTouch
和 ,connectionStatusChanged
都使用顶部定义的 var 会话。
我要问的是:我将如何在var session:VCSimpleSession
?
非常感谢!
