问题描述
代码如下，ENUM已经定义在Account.h文件里面了
typedef NS_ENUM(NSUInteger, httpMethod){ GET = 0, POST, PUT, DELETE};//方法定义-(void) location:(httpMethod)httpMethod withLocation:(NSString *)location;//在别的类里，调用方法，我想这么做，但是不知道正确的语法[self.myAccount Account.httpMethod.PUT location: withLocation:location];
问题解答
回答1：你这么定义只能
[self.myAccount location:GET withLocation:location];
推荐把enum定义成如下：
typedef NS_ENUM(NSUInteger, HttpMethod) { HttpMethodGet, HttpMethodPost, HttpMethodPut, HttpMethodDelete,}[self.myAccount location:HttpMethodGet withLocation:location];
swift是可以做到你的要求的。
enum HttpMethod { case GET case POST}func a(m : HttpMethod, b : String) { // ...}a(.GET, 'hello world')
