Parse Issue in Xcode 4.6.3 - "Expected a type" - Can't find the error
提问by Robin des Bois
I have a Problem with Xcode:
我的 Xcode 有问题：
At the moment I am working on an application for iOS SDK 6.1. Somedays ago I was implementing some methods and tried to compile the project. Then something strange happened:
目前我正在为 iOS SDK 6.1 开发一个应用程序。前几天我正在实现一些方法并尝试编译该项目。然后奇怪的事情发生了：
Compilation failed and I got some errors (see picture below) in two files, which aren't related to the methods I worked on.
编译失败，我在两个文件中出现了一些错误（见下图），这与我使用的方法无关。
I searched for errors in my code but couldn't find any.
Then I closed the project and opened it again: They were still here.
Then I closed the project and Xcode and reopened both: They were still here.
Then I created a new project and copied all the code: The issue appeared again.
我在我的代码中搜索错误，但找不到任何错误。
然后我关闭了项目并再次打开它：他们还在。
然后我关闭了项目和 Xcode 并重新打开它们：它们还在。
然后我新建了一个项目，复制了所有的代码：问题又出现了。
Now I am stuck and have no clue what to do. Do I miss something in my code?
现在我被卡住了，不知道该怎么办。我是否遗漏了代码中的某些内容？
Please help me!
请帮我！

Here are some code snippets, which should show my code after I followed the suggestions of Martin R:
以下是一些代码片段，在我遵循 Martin R 的建议后，它们应该会显示我的代码：
// PlayingCardDeck.h
@class PlayingCard;
@interface PlayingCardDeck : NSObject
- (void) addCard: (PlayingCard *) card atTop: (BOOL) atTop;
- (PlayingCard *) drawRandomCard;
- (BOOL) containsCard: (PlayingCard *) card;
- (BOOL) isCardUsed: (PlayingCard *) card;
- (void) drawSpecificCard: (PlayingCard *) card;
- (void) reset;
@end
// PlayingCardDeck.m
#import "PlayingCardDeck.h"
@interface PlayingCardDeck()
// PlayingCard.h
#import <Foundation/Foundation.h>
#import "RobinsConstants.h"
#import "PlayingCardDeck.h"
//@class PlayingCardDeck;
@interface PlayingCard : NSObject
+ (NSArray*) suitStrings;
+ (NSArray*) rankStrings;
+ (NSUInteger) maxRank;
- (id)initCardWithRank: (NSUInteger) r andSuit: (NSString*) s;
- (NSString*) description;
- (NSUInteger) pokerEvalRankWithDeck: (PlayingCardDeck *) deck;
- (NSAttributedString *) attributedContents;
- (BOOL) isEqual:(PlayingCard*)object;
@property (strong, nonatomic) NSString *contents;
@property (nonatomic, getter = isUsed) BOOL used;
@property (nonatomic, readonly) NSInteger rank;
@property (nonatomic, readonly, strong) NSString * suit;
@end
// PlayingCard.m
#import "PlayingCard.h"
@interface PlayingCard()

That looks like a typical "import cycle":
这看起来像一个典型的“导入周期”：
// In PlayingCardDeck.h:
@import "PlayingCard.h"
// In PlayingCard.h:
@import "PlayingCardDeck.h"
Replacing one of the @importstatements by @classshould solve the problem, e.g.
替换其中一个@import语句@class应该可以解决问题，例如
// In PlayingCardDeck.h:
@class PlayingCard; // instead of @import "PlayingCard.h"
And in the implementation file you have to import the full interface:
在实现文件中，您必须导入完整的接口：
// In PlayingCardDeck.m:
#import "PlayingCardDeck.h"
#import "PlayingCard.h" // <-- add this one

There is something wrong in PlayingCard.h. This error causes the compiler to not know what a "PlayingCard *" is. Can you show the code from PlayingCard.h?
PlayingCard.h 有问题。此错误导致编译器不知道“PlayingCard *”是什么。你能显示 PlayingCard.h 中的代码吗？
回答by Mario
Make sure the PlayingCard.m is added to your applications target! I would think it isn't (click the .m file and check your apps target in the inspector window on the right side pane)
确保将 PlayingCard.m 添加到您的应用程序目标！我认为它不是（单击 .m 文件并在右侧窗格的检查器窗口中检查您的应用程序目标）
