xcode osx webview new window

Question

我对网络视图有问题。

我

为Osx制作了一个简单的网络浏览器，在里面我必须隐藏nvigation栏，菜单和右键单击，用户只能进入一个特定的url。

所有这些都没关系，但我需要允许_blank目标..我的意思是..我有一些链接的目标_blank，所以在新窗口中打开，但它不起作用，我不知道允许这样做。

这是我的DataOAppDelegate.h代码：

    #import <Cocoa/Cocoa.h>
#import <WebKit/WebKit.h>
@interface DataOAppDelegate : NSObject <NSApplicationDelegate,NSWindowDelegate>
{WebView *WebView;
    //other instance variable
}
@property (assign) IBOutlet NSWindow *window;
@property (retain, nonatomic) IBOutlet WebView *myWebView;

@end

和 DataOAppDelegate.m 的代码

#import "DataOAppDelegate.h"
//#import <WebKit/WebKit.h>

@implementation DataOAppDelegate
@synthesize window;
@synthesize myWebView;
//your function etc

-(void)awakeFromNib{
    NSString *urlText = @"http://website.com";
    [[myWebView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlText]]];
    [myWebView setDrawsBackground:NO];
    [window setDelegate:self];
}

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    [myWebView setUIDelegate:self];
    NSString *urlText = @"http://website.com";
    [[myWebView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlText]]];
}

- (WebView *)myWebView:(WebView *)sender createWebViewWithRequest:(NSURLRequest *)request
{
    NSLog(@"sss%@",sender);
    NSUInteger windowStyleMask =    NSClosableWindowMask |
    NSMiniaturizableWindowMask |
    NSResizableWindowMask |
    NSTitledWindowMask;
    NSWindow* webWindow = [[NSWindow alloc] initWithContentRect:NSMakeRect(0, 0, 800, 600) styleMask:windowStyleMask backing:NSBackingStoreBuffered defer:NO];
    WebView* newWebView = [[WebView alloc] initWithFrame:[webWindow contentRectForFrameRect:webWindow.frame]];
    [newWebView setAutoresizingMask:NSViewWidthSizable|NSViewHeightSizable];
    [webWindow setContentView:newWebView];
    [webWindow center];
    [webWindow makeKeyAndOrderFront:self];
    [[newWebView mainFrame] loadRequest:request];
    return newWebView;
}
- (void)launchSoftWithBundleID:(NSString *)softPath
{
    NSBundle *softBundle = [NSBundle bundleWithPath:softPath];
    NSString *bundleID = [softBundle bundleIdentifier];
    //
    NSTask *softTask = [[NSTask alloc] init];
    [softTask setLaunchPath:softPath];
    [softTask launch];
    //
    NSArray *array = [NSRunningApplication runningApplicationsWithBundleIdentifier:bundleID];
    if ([array count] > 0)
    {
        NSRunningApplication *runningApp = [array objectAtIndex:0];
        [runningApp activateWithOptions:NSApplicationActivateIgnoringOtherApps];
    }
}

WebViews具有委托方法：decidePolicyForNavigationAction和decidePolicyForNewWindowAction（文档）。

- (void)webView:(WebView *)sender decidePolicyForNavigationAction:(NSDictionary *)actionInformation request:(NSURLRequest *)request frame:(WebFrame *)frame decisionListener:(id)listener {
    if ([sender isEqual:self.YourVebView]) {
        [listener use];
    }
    else {
        [[NSWorkspace sharedWorkspace] openURL:[actionInformation objectForKey:WebActionOriginalURLKey]];
        [listener ignore];
    }
}
- (void)webView:(WebView *)sender decidePolicyForNewWindowAction:(NSDictionary *)actionInformation request:(NSURLRequest *)request newFrameName:(NSString *)frameName decisionListener:(id<WebPolicyDecisionListener>)listener {
    [[NSWorkspace sharedWorkspace] openURL:[actionInformation objectForKey:WebActionOriginalURLKey]];
    [listener ignore];
}

注意：不要忘记为 Web 视图设置策略委托。
