台風注入-使用初始化程序注入參數時崩潰

Question

我正在遵循Typhoon Coredata示例（ https://github.com/appsquickly/Typhoon-CoreData-RAC-Example ）快速配置coredata。

但是我在以下方法中遇到異常

public dynamic func managedObjectModel() -> AnyObject {
        return TyphoonDefinition.withClass(NSManagedObjectModel.self){
            (definition) in
            definition.useInitializer("contentsOfURL:"){
                (initializer) in
                 initializer.injectParameterWith(self.modelUrl())
            }
        }
    }

在上面的函數中，我試圖將modelurl注入NSManagedObjectModel類的“ contentsOfURL”方法。 但我得到以下錯誤

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Method 'contentsOfURL:' not found on 'NSManagedObjectModel'. Did you include the required ':' characters to signify arguments?'

//

//NSManagedObjectModel class  
    public convenience init?(contentsOfURL url: NSURL)

Answer 1

definition.useInitializer("initWithContentsOfURL:")
