Swift:当前配置的占位符

Question

我正在阅读 example用于拥有多个配置并在运行时使用以下 Objective C 代码访问事件配置:

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

用于获取事件配置值的 @"Configuration" 的 Swift 等效项是什么？

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@，它就会起作用:

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