Cocoa 如何在打开应用程序时启动网页

大家好，我需要帮助。我正在尝试在Xcode 4.0中为mac制作一个应用程序，我希望它在发布时显示一个网页。我已经添加了webkit框架，并获得了一些代码，但它不起作用。代码如下

app delegate.m文件

#import "AppDelegate.h"

#import <WebKit/WebKit.h>

@implementation AppDelegate

@synthesize window = _window;


@synthesize WebView;

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    NSString *urlAddress = @"http://www.google.com/";
    NSURL *url = [NSURL URLWithString:urlAddress];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [[WebView mainFrame] LoadRequest:requestObj];
}

@end

和app delegate.h文件

#import <Cocoa/Cocoa.h>

 #import <WebKit/WebKit.h>

@interface AppDelegate : NSObject <NSApplicationDelegate>

@property (assign) IBOutlet NSWindow *window;

@property (assign) IBOutlet WebView *WebView;

@interface myAppDelegate : NSObject <NSApplicationDelegate> {
    WebView *myWebView;

}

@property (retain, nonatomic) IBOutlet WebView *myWebView;

@end

---

如果有人能帮忙，请尽快回复谢谢大家

嗯，我假设代码没有编译？不应该这样。.h应该看起来像：

#import <Cocoa/Cocoa.h>

#import <WebKit/WebKit.h>

@interface AppDelegate : NSObject <NSApplicationDelegate> {
    WebView *_myWebView; // not needed if you're using the latest xcode
}

@property (assign) IBOutlet NSWindow *window;
@property (retain, nonatomic) IBOutlet WebView *myWebView;

@end

m：

#import "AppDelegate.h"

#import <WebKit/WebKit.h>

@implementation AppDelegate

@synthesize window = _window;
@synthesize myWebView = _myWebView;

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    NSString *urlAddress = @"http://www.google.com/";
    NSURL *url = [NSURL URLWithString:urlAddress];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [[self.myWebView mainFrame] loadRequest:requestObj]; // note the lower case 'l' in 'loadRequest'
}

@end

这假设您已将.xib中的webview与myWebView属性连接起来。

谢谢您修复了它。另一个原因是我忘了将web视图与myWebView属性连接起来
