在这里看了一会儿,但似乎无法找到一个有效的解决方案.
我试图在Swift中禁用滑动以返回上一个视图手势.
我尝试了各种解决方案,包括:
self.navigationController?.interactivePopGestureRecognizer.enabled = false
和
self.navigationController.interactivePopGestureRecognizer.delegate = self
func gestureRecognizerShouldBegin(gestureRecognizer: UIGestureRecognizer!) -> Bool {
return false
}
是否有一种新方法可以做到这一点或其他方法有效？
我正在尝试AVPlayer在纯Swift中实现一个观察者.
我收到错误:"收到邮件但未处理".是因为我正在使用的观察者的构造函数中的object参数是nil？
我在下面放置了我的示例代码:
player.addObserver(self, forKeyPath: "status", options:NSKeyValueObservingOptions(), context: nil)
player.addObserver(self, forKeyPath: "playbackBufferEmpty", options:NSKeyValueObservingOptions(), context: nil)
player.addObserver(self, forKeyPath: "playbackLikelyToKeepUp", options:NSKeyValueObservingOptions(), context: nil)
player.addObserver(self, forKeyPath: "loadedTimeRanges", options: NSKeyValueObservingOptions(), context: nil)
private func deallocObservers(player: AVPlayer) {
player.removeObserver(self, forKeyPath: "status")
player.removeObserver(self, forKeyPath: "playbackBufferEmpty")
player.removeObserver(self, forKeyPath: "playbackLikelyToKeepUp")
}
//observer for av play
override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
if keyPath == "status" {
print("Change at keyPath = \(keyPath) for \(object)")
}
if …收到此错误:mvn包
它无法每次都使用相同的错误构建,我尝试重命名工件,以及更改pom文件中的构建依赖项.请在下面查看更多详情:
任何帮助将非常感谢.错误:

码:
零件:
.component('player', {

bindings: {
genre: '=',
track: '=',
ngAudio: '<'
},

// The controller that handles our component logic
controller : function($scope, ngAudio) {

//$scope.ngAudio = ngAudio;
ngAudio.play("https://api.soundcloud.com/tracks/167999916/stream?client_id=123456576789");

我正在尝试正确设置已播放的播放时间.当调用player.seek功能或暂停曲目时,不会更新nowplayinginfocenter经过的时间.我现在使用setNowPlaying()初始化inffinenter,然后在寻求在信息中心更新它时调用setNowPlayingCurrentTime.
但是,当调用此值时,经过的时间将重置为0.
任何建议都非常有用.

//set now playing info center
if NSClassFromString("MPNowPlayingInfoCenter") != nil {

var data = NSData(contentsOfURL: url!)

MPMediaItemPropertyArtwork: albumArt,

我将材质引导脚本包含在我的Angular项目的index.html中,但是需要手动将它们重新包含在视图中才能工作.
这很奇怪,因为插入Angular的所有其他脚本都不会发生这种情况.
的index.html
<script src="bower_components/bootstrap-material-design/scripts/material.js"></script>
<script src="bower_components/bootstrap-material-design/scripts/ripples.js"></script>
我还注意到材料引导程序与Grunt和Bower不能很好地兼容,并且在构建时往往会自行删除(因此手册包含在页面底部).
这些已知的错误有Material-boostrap和Angular/Bower/Grunt还是我做错了什么？
如果您还有其他要求,请告诉我!
