小编vvw*_*vvw的帖子

在xcode 7 beta3中

当我使用object-c时没问题,但是当我使用swift时,我收到一个错误:"在这台服务器上找不到请求的URL",为什么？

这是代码:

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


@interface ViewController ()

    @property(strong,nonatomic) WKWebView *webView;

@end

@implementation ViewController


- (void)viewDidLoad {
    [super viewDidLoad];

    NSURL *url = [NSURL URLWithString:@"http://www.apple.com"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    _webView = [[WKWebView alloc] initWithFrame:self.view.frame];
    [_webView loadRequest:request];
    [self.view addSubview:_webView];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end 


swift:

import UIKit
import WebKit

class ViewController: UIViewController,WKNavigationDelegate {

    var webview: WKWebView?

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override …
