UITableView prepareForSegue不推送到UIWebView

我試圖從WebListViewController推到WebPageViewController，所以當一個單元格被按下時，它會推送到一個UIWebView來顯示與之相關的網頁文章。但我就是不能讓它working-UITableView prepareForSegue不推送到UIWebView

WebListViewController.m

#import "WebListViewController.h" 
#import "Feed.h" 

@interface WebListViewController() 
@property (strong, nonatomic) NSArray *headlinesArray; 
@end 

@implementation WebListViewController 
@synthesize tableView = _tableView; 
@synthesize headlinesArray; 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 

    static NSString *CellIdentifier = @"standardCell"; 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

    Feed *feedLocal = [headlinesArray objectAtIndex:indexPath.row]; 
    NSString *headlineText = [NSString stringWithFormat:@"%@", feedLocal.headline]; 
    cell.textLabel.text = headlineText; 

    return cell; 
} 


- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender 
{ 
    if ([segue.identifier isEqualToString:@"webpage"]) { 
    UITableViewCell *cell = (UITableViewCell*)sender; 
    NSIndexPath *indexPath = [self.tableView indexPathForCell:cell]; 

    WebPageViewController *wpvc = (WebPageViewController *) [segue destinationViewController]; 
    wpvc.buttonNumber = _buttonNumber; 
    Feed *feedLocal = [headlinesArray objectAtIndex:indexPath.row]; 
    NSString *stringWeb = [NSString stringWithFormat:@"%@", feedLocal.links.web.href]; 
    wpvc.stringWeb = stringWeb; 
}

}

WebPageViewController.h

@interface WebPageViewController : UIViewController <UIWebViewDelegate> 
@property (nonatomic) int buttonNumber; 
@property (strong, nonatomic) IBOutlet UIWebView *webView; 
@property (strong, nonatomic) NSString *stringWeb; 
@end

WebPageViewController.m

#import "WebPageViewController.h" 
#import "Feed.h" 

@interface WebPageViewController() 
@property (strong, nonatomic) NSArray *headlinesArray; 
@end 
@implementation WebPageViewController 
@synthesize stringWeb; 
@synthesize headlinesArray; 

-(void)viewWillAppear:(BOOL)animated { 
    NSURL *url = [NSURL URLWithString:stringWeb]; 
    [self.webView loadRequest:[NSURLRequest requestWithURL:url]]; 
} 

-(void)viewWillDisappear:(BOOL)animated { 
    [self.webView stopLoading]; 
}

JSON響應

{ 
    "timestamp": "2013-05-04T16:38:48Z", 
    "feed": [{ 
     "headline": "Text of headline", 
     "links": { 
      "web": { 
       "href": "http://website.com/article" 
      },

我剛添加的<UIWebViewDelegate>部分，因爲今天我想也許這就是發生了什麼事，但它仍然是行不通的。我知道cellForRowAtIndexPath是正確的，因爲我在控制檯中看到了所有正確的數據。當我運行該程序時，它似乎甚至沒有進入WebPageViewController，所選的單元格保持突出顯示。我不知道是什麼問題，如果它的prepareForSegue或需要添加didSelectRowAtIndexPath或不同的東西。

（我是從一個API拉JSON數據。）

任何意見將是有益的超級，我會添加所需的任何代碼，謝謝！
