objective-c - 枚举值 'SHKShareTypeUndefined' 未在开关中处理

Question

我在下面的代码中收到警告 Enumeration value 'SHKShareTypeUndefined' not handled in switch。我将相关的行和指针加粗了:

    + (NSArray *)favoriteSharersForType:(SHKShareType)type
{   
    NSArray *favoriteSharers = [[NSUserDefaults standardUserDefaults] objectForKey:[NSString stringWithFormat:@"%@%i", SHK_FAVS_PREFIX_KEY, type]];

    // set defaults
    if (favoriteSharers == nil)
    {
        switch (type) 
        {
            case SHKShareTypeURL:
                favoriteSharers = [NSArray arrayWithObjects:@"SHKTwitter",@"SHKFacebook",@"SHKReadItLater",nil];
                break;

            case SHKShareTypeImage:
                favoriteSharers = [NSArray arrayWithObjects:@"SHKMail",@"SHKFacebook",@"SHKCopy",nil];
                break;

            case SHKShareTypeText:
                favoriteSharers = [NSArray arrayWithObjects:@"SHKMail",@"SHKTwitter",@"SHKFacebook", nil];
                break;

            case SHKShareTypeFile:
                favoriteSharers = [NSArray arrayWithObjects:@"SHKMail", nil];
                break;

            case SHKShareTypeUndefined:         
                break;
        }

        // Save defaults to prefs
        [self setFavorites:favoriteSharers forType:type];
    }

此警告在 ShareKit 中，我不确定如何修复它。

谢谢!

为该枚举值添加虚拟大小写:

case SHKShareTypeUndefined:         
     break;

或者在目标设置(警告部分)中将“检查开关语句”标志设置为 NO
