我在純Objective-C中製作超簡單的單頁瀏覽器,除了鍵盤事件以外,一切都很好。我只是無法使用鍵盤在webforms中輸入任何數據!鼠標操作,如粘貼在webforms和點擊鏈接的作品,但輸入webforms不!Cocoa WebView不響應鍵盤事件

代碼:

#import <WebKit/WebKit.h> 

@interface MyWebView : WebView 
{ 
} 
@end 

@implementation MyWebView 

-(void)windowWillClose:(NSNotification *)notification 
{ 
    [NSApp terminate:self]; 
} 

-(BOOL)becomeFirstResponder 
{ 
    printf("becomeFirstResponder\n"); // this message always appears 
    return YES; 
} 

-(void)keyDown:(NSEvent *)event 
{ 
    printf("keydown\n"); // this message never appears 
    // should I use this code to make keyboard work? 
    [self interpretKeyEvents:[NSArray arrayWithObject:event]]; 
} 

@end 

int main(void) { 
    NSRect contentRect; 
    NSWindow *window = nil; 
    WebView *webView = nil; 
    NSString *urlForAuthentication = nil; 

    NSApp = [NSApplication sharedApplication]; 

    contentRect = NSMakeRect(100, 100, 700, 700); 
    window = [[NSWindow alloc] initWithContentRect:contentRect styleMask:NSTitledWindowMask|NSClosableWindowMask|NSMiniaturizableWindowMask backing:NSBackingStoreBuffered defer:NO]; 
    if (!window) { 
     printf("!window\n"); 
     goto end; 
    } 
    webView = [[MyWebView alloc] initWithFrame:window.contentLayoutRect frameName:nil groupName:nil]; 
    if (!webView) { 
     printf("!webView\n"); 
     goto end; 
    } 

    urlForAuthentication = [[NSString alloc] initWithCString:(const char *)"https://yahoo.com" encoding:NSUTF8StringEncoding]; 
    [[webView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlForAuthentication]]]; 
    window.contentView = webView; 
    window.delegate = (id)webView; 
    [window makeFirstResponder:webView]; 
    [window makeKeyAndOrderFront:nil]; 
    [window makeMainWindow]; 

    if (!window.keyWindow) 
     printf("not keyWindow\n"); // this message always appears 
    if (!window.mainWindow) 
     printf("not mainWindow\n"); // this message always appears 
    [NSApp run]; 

end: 
    [urlForAuthentication release]; 
    [webView release]; 
    [window release]; 
    [NSApp release]; 
    return 0; 
} 

生成文件:

CC=clang 

FRAMEWORKS:=/System/Library/Frameworks/WebKit.framework/WebKit /System/Library/Frameworks/AppKit.framework/AppKit 
LIBRARIES:= 
WARNINGS=-Wall -Werror 

SOURCE=app.m 

CFLAGS=-g -v $(WARNINGS) $(SOURCE) 
LDFLAGS=$(LIBRARIES) $(FRAMEWORKS) $(LINK_WITH) 
OUT=-o app 

all: 
    $(CC) $(CFLAGS) $(LDFLAGS) $(OUT) 

我做錯了嗎?我已閱讀文檔並在SO上搜索了類似的問題,但我找不到解決方案。我試圖捕獲keyDown事件,但它不會發生。我試圖讓我的窗口關鍵和主要,但看似不成功。

你好,歡迎來到stackoverflow。爲什麼不應該使用簡單的appkit XCode模板?僅僅實現一個webview可能會容易得多。 – Astoria

是的,@Astoria當然你是對的,但在這個小程序的情況下,我寧願不要使用大的XCode!說實話,我不喜歡這個IDE。 –

@Astoria有趣的事實:這個代碼實際上在將它插入XCode模板並刪除發送'release'消息的行之後就開始了。謝謝你的提示,我會更深入地挖掘它! –

可能關注的人:將您的可執行文件'abc'放入文件夾'abc.app/Contents/MacOS/'中,它會最終正常工作!
