Iphone 使用地理位置类生成时出现警告

我还在模拟器上工作，正在等待设备上的测试，在等待过程中，我希望与您分享我的代码，希望您能帮助我找出5个警告的原因 我的应用程序由两类组成：CoreLocationController和GeoLocationViewController

CoreLocationController是假定充当核心位置管理器委托的类。这个类将从包含原始数据的核心位置框架接收消息，然后稍后将其传递给我们的视图控制器类。 CoreLocationController.h

#import <Foundation/Foundation.h>
#import <CoreLocation/CoreLocation.h>

@protocol CoreLocationControllerDelegate
@required
-(void)LocationUpdate:(CLLocation*)location;//Our location updates are sent here
-(void)locationError:(NSError*)error;//Any errors are sent here
@end
@interface CoreLocationController : NSObject<CLLocationManagerDelegate> {

    CLLocationManager *locMgr;
    id delegate;
}
@property(nonatomic,retain)CLLocationManager *locMgr;
@property(nonatomic,assign)id delegate;
@end

GeoLocationViewController.h:

#import <UIKit/UIKit.h>
#import "CoreLocationController.h"
@interface GeoLocationViewController : UIViewController <CoreLocationControllerDelegate> {

    CoreLocationController *CLController;
    IBOutlet UILabel *locLabel;

}
@property (nonatomic,retain)CoreLocationController *CLController;
@end

#import "GeoLocationViewController.h"

@implementation GeoLocationViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    CLController=[[CoreLocationController alloc] init];
    CLController.delegate=self;
    [CLController.locMgr startUpdatingLocation];
}

-(void)locationUpdate:(CLLocation *)location    {

    locLabel.text=[location description];

}
-(void)locationError:(NSError *)error   {

    locLabel.text=[error description];
}
- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}
- (void)dealloc {

    [CLController release];
    [super dealloc];
}

@end

warning: property 'CLController' requires method '-CLController' to be defined - use @synthesize, @dynamic or provide a method implementation


 warning: property 'CLController' requires the method 'setCLController:' to be defined - use @synthesize, @dynamic or provide a method implementation


 warning: incomplete implementation of class 'GeoLocationViewController'


 warning: method definition for '-LocationUpdate:' not found


warning: class 'GeoLocationViewController' does not fully implement the 'CoreLocationControllerDelegate' protocol

现在查看我收到的警告：

#import <UIKit/UIKit.h>
#import "CoreLocationController.h"
@interface GeoLocationViewController : UIViewController <CoreLocationControllerDelegate> {

    CoreLocationController *CLController;
    IBOutlet UILabel *locLabel;

}
@property (nonatomic,retain)CoreLocationController *CLController;
@end

#import "GeoLocationViewController.h"

@implementation GeoLocationViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    CLController=[[CoreLocationController alloc] init];
    CLController.delegate=self;
    [CLController.locMgr startUpdatingLocation];
}

-(void)locationUpdate:(CLLocation *)location    {

    locLabel.text=[location description];

}
-(void)locationError:(NSError *)error   {

    locLabel.text=[error description];
}
- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}
- (void)dealloc {

    [CLController release];
    [super dealloc];
}

@end

请回答最后一个问题，如果我的构建成功运行，但我的代码没有显示任何有关地理位置的信息，我是否应该等待在设备上测试我的构建以对其进行判断？？？

第一个警告（以及下两个警告，它们是相同的）：

这意味着，在@implementation之后，您需要在GeoLocationViewController.m文件中@synthesis CLController。但是，它仍然可以工作，因为您没有将其作为类内的属性引用（即，您没有使用

self.CLController

引用它，而只是

CLController

。因此只需将

@synthesis-CLController

放在@implementation for GeoLocationViewController.m之后

第二个错误

warning: incomplete implementation of class 'GeoLocationViewController'
warning: method definition for '-LocationUpdate:' not found

---

您没有在GeoLocationViewController.h文件中指定LocationUpdate作为方法。

在复制粘贴到此处之前，您是否查看了警告？好的，例如，我不知道这是什么：警告：类“GeoLocationViewController”的未完全实现意味着，我始终实现了一些方法，并对其他方法进行了注释：）还有：警告：“GeoLocationViewController”类没有完全实现“CoreLocationControllerDelegate”协议。我应该实现整个协议吗！！或者忽略它您永远不应该忽略警告，尤其是在Objective-C中，因为它们通常会导致运行时崩溃，因为它是一种基于消息的语言-许多东西不会生成编译时错误，但会在运行时崩溃。也就是说，是的，我现在明白问题是什么了：在您的委托中，您定义了LocationUpdate，但在下面，您使用小写L来实现它。尝试在实现中将其更改为大写，以匹配协议
