Objective-c （c#）：在 -init 时调用（void）方法-解网

问：

我正在尝试将 C# 代码重写为等效的 objective-c 代码，并在 -init 方法中调用 void 函数时遇到某种麻烦。

C# 代码中有两个构造函数，其中一个使用不同的参数调用 void 方法。我不知道如何在 objective-c 中处理它（感觉像个新手）。我很乐意接受任何建议！

当我在 .h 文件中将“-（void）”更改为“+（void）”时（“+”类似于 c# 中的静态，所以我先尝试了一下），我得到：

No visible @interface for 'OnlineAdapter' declares the selector 
'getConfigInfoWithConfigUrl:AndServiceUrl:AndClientName:AndClientSecret:AndDirections:'

当我使用“-（void）”调用时，出现错误：

    Use of undeclared identifier '_clinetSecret';
did you mean '_clientSecret'? //etc. for other args

我想这是因为 C# 代码中的“out”attr 而发生的，但我不确定 obj-c 中是否有类似物。

Objective-c 让我的大脑崩溃。任何帮助将不胜感激！

你拼错了 “client” “clinet”

self在 Objective-C 中，仅隐式用于访问实例变量（ivar），而不用于方法调用。因此，您始终需要使用以下语法：

[self getConfigInfoWithConfigUrl: _configUrl];

请注意，方法名称在 .h 文件中的声明中有拼写错误。

事实上，您从任何其他方法执行此操作并没有什么区别。init…

当我在 .h 文件中将“+”更改为“-”时，我收到另一个错误（似乎是 obj-c 中缺少“out”attr 类似物的原因）：使用未声明的标识符“_clinetSecret”;你是说“_clientSecret”吗？嗯，看起来很奇怪

您没有显示 Objective-C 方法的代码。由于 C# 方法是静态方法，因此您可能希望将 Objective-C 方法设为类方法，并使用以下声明：getConfigInfoWithConfigUrl:AndServiceUrl:AndClientName:AndClientSecret:AndDirections:GetConfigInfogetConfigInfoWithConfigUrl:AndServiceUrl:AndClientName:AndClientSecret:AndDirections:++(void) getConfigInfoWithConfigUrl: ...

类方法需要在类对象上调用，而不是在普通实例上调用：[Adapter getConfigInfoWithConfigUrl: ...]

outC# 中的参数表示参数是通过引用传递的。在 C 语言中，我们通常通过传递指向变量的指针来完成等效的事情。ref

所以它应该声明如下：

+ (void)getConfigInfoWithConfigUrl:(NSString *)_configUrl
                     AndServiceUrl:(NSString **)_servireUrl
                     AndClientName:(NSString **)_clientName
                   AndClientSecret:(NSString **)_clientSecret
                     AndDirections:(NSArray**)directions;

在方法中，它将分配给如下所示的变量：

*serviceUrl = ...
*clientName = ...
*clientSecret = ...
*directions = ...

你这样称呼它：

[Adapter getConfigInfoWithConfigUrl:_configUrl 
                      AndServiceUrl:&_servireUrl
                      AndClientName:&_clientName 
                    AndClientSecret:&_clientSecret
                      AndDirections:&directions];
