[NSCharacterSet whitespaceAndNewlineCharacterSet]];
[self.workingPropertyString setString:#""]; // clear the string for next time
if ([elementName isEqualToString:kIDStr])
{
self.workingEntry.appURLString = trimmedString;
}
else if ([elementName isEqualToString:kNameStr])
{
self.workingEntry.appName = trimmedString;
}
else if ([elementName isEqualToString:kImageStr])
{
self.workingEntry.imageURLString = trimmedString;
}
else if ([elementName isEqualToString:kUrlStr])

RootViewController.m in tableView didSelectRowAtIndexPath
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
AppRecord *appRecord = [self.entries objectAtIndex:indexPath.row];
NSString *urlAddress = appRecord.appURL;
NSURL *url = [NSURL URLWithString:urlAddress];
WebViewController *detailViewController = [[WebViewController alloc] initWithNibName:#"WebViewController" bundle:nil];
// WebViewController.sites= [_entries objectAtIndex:indexPath.row];
[detailViewController.webView loadRequest:[NSURLRequest requestWithURL:url]];
[self.navigationController pushViewController:detailViewController animated:YES];
}
WebViewController.h
#interface WebViewController : UIViewController <UIWebViewDelegate>
#property (nonatomic, strong) IBOutlet UIWebView *webView;
The table load fine, and it push to WebViewController when i selected cell but the UIWebView didn't load the web page, it's only blank (white).
can anyone help me to fix it?
thanks so much!

I think the best way for you is to pass the url from RootViewController to WebViewController and refresh your webview in WebViewController.
So you need to modify your code like this :
RootViewController.m in tableView didSelectRowAtIndexPath
// Add a #property of your detail view for lazing
#property (nonatomic, strong) WebViewController *detailViewController;
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
AppRecord *appRecord = [self.entries objectAtIndex:indexPath.row];
if (!_detailViewController)
self.detailViewController = [[WebViewController alloc] initWithNibName:#"WebViewController" bundle:nil];
self.detailViewController.websiteURL = appRecord.appURL;
[self.navigationController pushViewController:self.detailViewController animated:YES];
}
WebViewController.h
#interface WebViewController : UIViewController <UIWebViewDelegate>
#property (nonatomic, strong) IBOutlet UIWebView *webView;
#property (nonatomic, strong) NSString *websiteURL;
WebViewController.m
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
// URL Request Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:[NSURL URLWithString:_websiteURL]];
// Load the request in the UIWebView
[_webView loadRequest:requestObj];
}
