错误:预期的说明符限定符列表位于 'GKPeerPickerController 之前
我不断收到此消息(在标题中)。 如果您想了解我在做什么,请快速浏览一下我的代码。 我刚刚开始实现 Peer Picker,所以我还没有完全完成。 我只需要第一部分的一些建议/帮助。 该错误显示在两个 #import 语句之间的 .m 文件中,这意味着我在头文件中使用 GKPeerPickerController 的方式一定是错误的。
蓝牙_Ad_Hoc_NetworkAppDelegate.h
#import <UIKit/UIKit.h>
@class Bluetooth_Ad_Hoc_NetworkViewController;
@interface Bluetooth_Ad_Hoc_NetworkAppDelegate : NSObject <UIApplicationDelegate> {
UIWindow *window;
Bluetooth_Ad_Hoc_NetworkViewController *viewController;
GKPeerPickerController *picker;
GKSession *session;
IBOutlet UILabel *status;
NSData *data;
}
@property(nonatomic, retain)IBOutlet UILabel *status;
@property(nonatomic, retain)GKPeerPickerController *picker;
@property(nonatomic, retain)GKSession *session;
@property(nonatomic, retain)IBOutlet UIWindow *window;
@property(nonatomic, retain)IBOutlet Bluetooth_Ad_Hoc_NetworkViewController *viewController;
@end
蓝牙_Ad_Hoc_NetworkAppDelegate.m
#import "Bluetooth_Ad_Hoc_NetworkAppDelegate.h"
#import "Bluetooth_Ad_Hoc_NetworkViewController.h"
@implementation Bluetooth_Ad_Hoc_NetworkAppDelegate
@synthesize status;
@synthesize picker;
@synthesize session;
@synthesize window;
@synthesize viewController;
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Override point for customization after app launch
[window addSubview:viewController.view];
[window makeKeyAndVisible];
// allocate and initialize data
data = [[NSData alloc] initWithBytes:&status length:sizeof(status)];
// Allocate and setup peer picker controller
picker = [[GKPeerPickerController alloc] init];
picker.delegate = self;
picker.connectionTypesMask = GKPeerPickerConnectionTypeNearby;
[picker show];
}
- (void)dealloc {
[status release];
[viewController release];
[window release];
[super dealloc];
}
@end
I keep getting this message (in the title). Just take a quick look at my code if you want to see what I'm doing. I've just started implementing the Peer Picker, so I'm not completely done yet. I just need some advice/help in the first part. The error shows up in the .m file between the two #import statements, which means it has to be some wrong way that I've used the GKPeerPickerController in the header file.
Bluetooth_Ad_Hoc_NetworkAppDelegate.h
#import <UIKit/UIKit.h>
@class Bluetooth_Ad_Hoc_NetworkViewController;
@interface Bluetooth_Ad_Hoc_NetworkAppDelegate : NSObject <UIApplicationDelegate> {
UIWindow *window;
Bluetooth_Ad_Hoc_NetworkViewController *viewController;
GKPeerPickerController *picker;
GKSession *session;
IBOutlet UILabel *status;
NSData *data;
}
@property(nonatomic, retain)IBOutlet UILabel *status;
@property(nonatomic, retain)GKPeerPickerController *picker;
@property(nonatomic, retain)GKSession *session;
@property(nonatomic, retain)IBOutlet UIWindow *window;
@property(nonatomic, retain)IBOutlet Bluetooth_Ad_Hoc_NetworkViewController *viewController;
@end
Bluetooth_Ad_Hoc_NetworkAppDelegate.m
#import "Bluetooth_Ad_Hoc_NetworkAppDelegate.h"

您是否已将此语句包含在头文件中?
您还需要包含 GameKit 框架。
Have you included this statement in the header file?
Also you need to include the GameKit framework.
