我正在尝试从 to 推送WebListViewController
,WebPageViewController
因此当按下一个单元格时,它将推送到 aUIWebView
以显示与其关联的网络文章。但我就是无法让它工作-
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 响应
{
"timestamp": "2013-05-04T16:38:48Z",
"feed": [{
"headline": "Text of headline",
"links": {
"web": {
"href": "http://website.com/article"
},
我今天刚刚添加了该<UIWebViewDelegate>
部分,因为我认为这可能是正在发生的事情,但它仍然无法正常工作。我知道cellForRowAtIndexPath
是正确的,因为我在控制台中看到了它的所有正确数据。当我运行程序时,它似乎甚至从未到达WebPageViewController
,选定的单元格保持突出显示。我无法弄清楚问题是什么,如果它prepareForSegue
或需要添加didSelectRowAtIndexPath
或不同的东西。
(我正在从 API 中提取 JSON 数据。)
任何建议都会非常有帮助,我会添加任何需要的代码,谢谢!
