从升级到Xcode 7.3 swift 2.2后，从swift调用obj-c枚举不起作用 [英] Calling obj-c enum from swift not working after upgrading to Xcode 7.3 swift 2.2

问题描述

代码在升级到7.1之前的Xcode 7.3和swift 2.2之前工作得很好。我也看过使用typedef NS_ENUM（NSUInteger，MyStatus）...的答案...但是如果可能，我不想更改现有的obj-c代码。

The code was working well before the upgrade to Xcode 7.3 from 7.1 and swift 2.2. I have also seen answers using the typedef NS_ENUM(NSUInteger, MyStatus)... but if possible, I prefer not to change the existing obj-c code.

在obj-c头文件中定义：

Defined in obj-c header file:

typedef enum {
    StatusPending,
    StatusTimeout,
    StatusSuccess,
    StatusFail
} MyStatus;

Swift文件中的声明：

Statement in Swift file:

/* some code to retrieve the status */

switch (status) {

case .StatusSuccess:
 /* do something */

/* other test cases omitted here */

default:

}

我尝试使用.rawValue，.value等，但我仍然收到错误：

I've tried using .rawValue, .value, etc, but I still get an error:

在MyStatus类型中未找到枚举大小写StatusSuccess

Enum case 'StatusSuccess' not found in type 'MyStatus'

在升级之前所有工作正常，并尝试卸载/重新安装Xcode 7.3，Product-> Clean ，Product-> Clean Build Folder ..但没有成功： - （

All was working fine before the upgrade and have tried uninstalling/reinstalling Xcode 7.3, Product->Clean, Product->Clean Build Folder.. but without success :-(

推荐答案

你不能声明typedef NS_ENUM（NSUInteger ，EnumName）{}在@interface和@end中，xcode 7.2的解析与xcode 7.3不同，所以只需在@interface @end块之外移动你的枚举声明，它应该可以正常工作，否则它被认为是私有声明

You can't declare "typedef NS_ENUM (NSUInteger, EnumName){}" within @interface and @end, the parsing of xcode 7.2 is different from xcode 7.3. So, just move your enum declarations outside @interface @end block and it should work fine, otherwise its considered a private declaration
