我正在尝试将C＃代码重写为等效的Objective-C代码，并在-init方法内部使用称为void函数的方法带来麻烦。
C＃代码中有两个构造函数，其中之一调用具有不同参数的void方法。我不知道如何在Objective-C中处理它（感觉像新手一样）。我很乐意接受任何建议！

当我在.h文件中将'-（void）'更改为'+（void）'时（“ +”在c＃中就像是静态的，因此我首先尝试过），我得到：
No visible @interface for 'OnlineAdapter' declares the selector
'getConfigInfoWithConfigUrl:AndServiceUrl:AndClientName:AndClientSecret:AndDirections:'
当我用'-（void）'呼叫时，出现错误：
Use of undeclared identifier '_clinetSecret';
did you mean '_clientSecret'? //etc. for other args
我想这是由于C＃代码中的'out'attr而发生的，但是我不确定obj-c中是否存在类似物。
Objective-c使我的大脑崩溃。任何帮助将不胜感激！
答案 0 :(得分：1)
您没有显示您的Objective-C方法getConfigInfoWithConfigUrl:AndServiceUrl:AndClientName:AndClientSecret:AndDirections:的代码。由于您的C＃方法GetConfigInfo是静态方法，因此您可能希望将Objective-C方法getConfigInfoWithConfigUrl:AndServiceUrl:AndClientName:AndClientSecret:AndDirections:设为类方法，并用+声明：+(void) getConfigInfoWithConfigUrl: ...
将需要在类对象上而不是在普通实例上调用类方法：[Adapter getConfigInfoWithConfigUrl: ...]
out和ref参数表示该参数是通过引用传递的。在C语言中，我们通常通过将指针传递给变量来完成等效操作。
因此应声明为以下内容：
+ (void)getConfigInfoWithConfigUrl:(NSString *)_configUrl
AndServiceUrl:(NSString **)_servireUrl
AndClientName:(NSString **)_clientName
AndClientSecret:(NSString **)_clientSecret
AndDirections:(NSArray**)directions;
在方法内部，它将分配给以下变量：
*serviceUrl = ...
*clientName = ...
*clientSecret = ...
*directions = ...
您这样称呼它：
[Adapter getConfigInfoWithConfigUrl:_configUrl
AndServiceUrl:&_servireUrl
AndClientName:&_clientName
AndClientSecret:&_clientSecret
AndDirections:&directions];
答案 1 :(得分：0)
self仅隐式用于访问实例变量（ivars），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文件的声明中有错字。
您通过init…与任何其他方法进行此操作的事实没有区别。
