我在为PhotoLibrary. 有谁知道那里有什么问题？
var albumPlaceholder:PHObjectPlaceholder!
//create the folder
NSLog("\nFolder \"%@\" does not exist\nCreating now...", albumName)
PHPhotoLibrary.sharedPhotoLibrary().performChanges({
let request = PHAssetCollectionChangeRequest.creationRequestForAssetCollectionWithTitle(albumName)
albumPlaceholder = request.placeholderForCreatedAssetCollection
},
completionHandler: {(success:Bool, error:NSError!)in
NSLog("Creation of folder -> %@", (success ? "Success":"Error!"))
self.albumFound = (success ? true:false)
if(success){
let collection = PHAssetCollection.fetchAssetCollectionsWithLocalIdentifiers([albumPlaceholder.localIdentifier], options: nil)
self.assetCollection = collection?.firstObject as PHAssetCollection
}
})
这段代码一直打印Error!在控制台上。提前致谢！
[更新] 我的错误是这样的。

我有一个带有填充颜色的 CAShapeLayer，并且想在这个形状的中心添加一个图标：
var shape = CAShapeLayer()
shape.fillColor = UIColor(white: 0.90, alpha: 1).CGColor
var image = UIImage(named: "some_image")
shape.contents = image?.CGImage
这段代码可以编译并显示灰色形状 - 但没有图像。:(
我查看了这些帖子，但我无法像他们那样投射 CGImage。
在 CALayer 中添加 UIImage并使用普通 CALayer 显示图像或 UIImage
还有其他方法吗？或者 id 转换的解决方法？

我无法获得editedVideoPath的完整NSURL，这是我的代码：
// GLOBAL VARIABLES
var videoPath = String()
var videoURL = NSURL()
// Video Editor delegate
func videoEditorController(editor: UIVideoEditorController, didSaveEditedVideoToPath editedVideoPath: String) {
if saveToPhotoLibrary {
if UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(editedVideoPath) {
UISaveVideoAtPathToSavedPhotosAlbum(editedVideoPath, self, nil, nil)
}
print("SAVED TO PHOTO LIBRARY AT: \(editedVideoPath)")
}
videoPath = editedVideoPath
videoURL = NSURL(string: editedVideoPath)!
print("VIDEO PATH: \(videoPath)")
print("VIDEO URL: \(videoURL)")
dismissViewControllerAnimated(true, completion: nil)
}
问题是我无法从videoPath字符串中获取完整的NSURL ，这是XCode控制台输出的内容：
VIDEO PATH: /private/var/mobile/Containers/Data/Application/D7536AD4-353A-48CA-8F31-2D78F9F10730/tmp/trim.BFF7D20F-138A-46A2-A58E-76736AF7343E.MOV
VIDEO URL: /private/var/mobile/Containers/Data/Application/D7536AD4-353A-48CA-8F31-2D78F9F10730/tmp/trim.BFF7D20F-138A-46A2-A58E-76 ... 343E.MOV
如您所见，VIDEO URL几乎在其末尾获得点，而VideoPath字符串是正确的。这是一个非常有线的问题，我从未在此NSURL语句中遇到过：
videoURL = NSURL(string: editedVideoPath)!
由于我需要将编辑后的视频上传到Web服务器，因此需要完整的正确URL。我以为是print（）的问题，但是如果我尝试抓住videoURL， …
