Question

我有一个WKWebView置于模态中的问题：

我打开并模态并在里面放置一个WKWebView。我加载一个网址，一切正常，直到我尝试单击（焦点）输入字段，然后它只是崩溃并关闭模式。有趣的是它可以在我的MAC上工作，但在另一个上却没有。两者都在使用MacOS Sierra 10.12.6

我还尝试了一个空白的html页面，其中只放置了一个输入并再次崩溃。

这是我的代码：

#import <Foundation/Foundation.h>
#import <Webkit/WebKit.h>

#include <iostream>
#include <cstdlib>
#include <cstring>
#include <unistd.h>
#include <sys/types.h>
#include <sys/ipc.h>
#include <sys/msg.h>
#define MSGSZ     128


using namespace std;

typedef struct msgbuf {
    long    mtype;
    char    mtext[MSGSZ];
} message_buf;


@interface Window_delegate : NSObject <NSWindowDelegate>
@end



@interface App_delegate : NSObject <NSApplicationDelegate>
@property (weak, nonatomic) NSWindow *_window;
@end

@implementation App_delegate

-(instancetype)init:(NSWindow*)parent_window
{
    if (self = [super init]) {
        self._window = parent_window;
        return self;
    }
    return nil;
}


-(void)applicationDidFinishLaunching:(NSNotification *)a_notification
{

    WKWebViewConfiguration *theConfiguration =
    [[WKWebViewConfiguration alloc] init];

    //    theConfiguration.suppressesIncrementalRendering=YES;

    WKWebView *wb = [[WKWebView alloc] initWithFrame:self._window.contentView.frame configuration:theConfiguration];
    wb.autoresizingMask = NSViewWidthSizable | NSViewHeightSizable;

    NSURL *url = [NSURL URLWithString: @"http://p416884.mittwaldserver.info/site/public"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];

    [wb loadRequest:request];
    wb.frame = CGRectMake(self._window.contentView.frame.origin.x,self._window.contentView.frame.origin.y, self._window.contentView.frame.size.width, self._window.contentView.frame.size.height);

    [self._window.contentView addSubview:wb];
}
@end


void start_program(void)
{
    NSApplication *app = [NSApplication sharedApplication];
    // Critical to have this so that you can add menus
    [NSApp setActivationPolicy:NSApplicationActivationPolicyRegular];


    NSWindow *window =
    [[NSWindow alloc]
     initWithContentRect:NSMakeRect(0, 0, 1200, 900) styleMask: NSWindowStyleMaskClosable backing: NSBackingStoreBuffered defer: YES];

    [window center];
    [window makeKeyAndOrderFront:window];
    [window setStyleMask:[window styleMask] | NSWindowStyleMaskTitled | NSWindowStyleMaskResizable];
    [window setTitle:@"Saint-Gobain Baustoffwelt"];


    App_delegate *application_delegate = [[App_delegate alloc] init:window];
    app.delegate = application_delegate;
    [app activateIgnoringOtherApps:YES];
    [app run];
}




int main(int argc, char **argv)
{
    //    std::cout << "Starting Application\n";


    @autoreleasepool {
        start_program();
    }

    return 0;

}

这是我在Console.app崩溃时得到的：link to screenshot

如果你能以某种方式帮助我，我将非常感激..

当关注文本输入，文本区域，数字输入时，WKWebView的模态关闭
