Swift：当前配置的占位符

Question

我正在阅读example有多个配置并在运行时使用此Objective C代码访问活动配置：

  NSBundle *bundle = [NSBundle mainBundle];
  NSString *path = [bundle pathForResource:@"Configuration" ofType:@"plist"];
  NSDictionary *config = [NSDictionary dictionaryWithContentsOfFile:path];

获取活动配置值的Swift等效于@"Configuration"是什么？

这不起作用：

var myDict: NSDictionary?
if let path = NSBundle.mainBundle().pathForResource(@"Configuration", ofType: "plist") {
    myDict = NSDictionary(contentsOfFile: path)
}

Answer 1

只需删除@，即可使用：

var myDict: NSDictionary?
if let path = NSBundle.mainBundle().pathForResource("Configuration", ofType: "plist") {
    myDict = NSDictionary(contentsOfFile: path)
}
