var anyError: NSError? = nil
var rsrc: NSNumber? = nil
var success = url.getResourceValue(&rsrc,forKey:NSURLIsUbiquitousItemKey,error:&anyError)

以上不编译：@H_403_4@

Cannot convert the expression's type 'Bool' to type 'inout Bool'

所以我试过这个：@H_403_4@

var anyError: NSError? = nil
var rsrc: AutoreleasingUnsafePointer<AnyObject?> = nil
var success = url.getResourceValue(rsrc,error:&anyError)

但这会产生EXC_BAD_ACCESS运行时错误.@H_403_4@

如何传递预期的第一个参数为AutoreleasingUnsafePointer< AnyObject？> (它应该指向一个布尔NSNumber根据doc),然后能够检查其预期的Bool值？@H_403_4@
