Question

我正在使用ECSlidingViewController，我的WebViewController类中有一个UIWebView。在不重新加载整个视图的情况下，当我单击MenuViewController.m类中的单元格时，我想将URL加载到UIWebView中。

这是我到目前为止所做的：

MenuViewController.m

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = nil;
if (cell == nil) {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"MyCell"];

}

NSString *pdfName = cell.textLabel.text;
WebViewController *webView = [[WebViewController alloc] init];

[webView setWebView:pdfName];

}

WebViewController.m

@interface WebViewController ()

@end

@implementation WebViewController
@synthesize WebView1;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
    // Custom initialization
}
return self;
}

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.


    self.view.layer.shadowOpacity = 0.7f;
    self.view.layer.shadowRadius = 10.0f;
    self.view.layer.shadowColor = [UIColor blackColor].CGColor;

     if(![self.slidingViewController.underLeftViewController isKindOfClass:[MenuViewController class]]) {
    self.slidingViewController.underLeftViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"Menu"];
}

    [self.view addGestureRecognizer:self.slidingViewController.panGesture];
    CGRect frame = WebView1.frame;

     frame.size.width = 280;       // Your desired width here.
    frame.size.height = 1;        // Set the height to a small one.

    WebView1.frame = frame;

    NSString *fullURL = @"http://www.sluggy.com";
    NSURL *url = [NSURL URLWithString:fullURL];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [WebView1 loadRequest:requestObj];

}

-(void)setWebView:(NSString *)pdfName{

    NSString *homeDir = NSHomeDirectory();
    NSString *filePath = [NSString stringWithFormat:@"%@/%@/%@", homeDir, @"Documents", pdfName];
    NSString *fullURL = @"http://www.google.com";
    NSURL *url = [NSURL URLWithString:fullURL];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

   [WebView1 loadRequest:requestObj];
    [WebView1 reload];
}

所以我知道我在某处遗漏了某些东西。有什么建议吗？

所以，我不得不以迂回的方式进行搜索，并找到了与更新标签有关的NSNotificationCenter。我将链接到描述如何执行此操作的页面，它的工作非常出色：

Update a label through button from different view
