    copied!<p>This is probably is pretty easy, but I'm stuck with it today. The idea is that in my browser, I've create uiwebview and I want to implimate address bar in popover with it own class. I can get the url from UItextfield from popover class to webview class, but when I get it uiwebview get lazy and it doesn't load it. When I check it, debuger says that webview is null. This is ViewController.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import "AdressBar.h" #import "mypopoverController.h" @interface ViewController : UIViewController&lt;AddressbarDelegate&gt; { UIWebView* mWebView; mypopoverController *popoverController; } @property (nonatomic, retain) IBOutlet UIWebView* webPage; @end </code></pre> <p>This is ViewController.m:</p> <pre><code> #import "mypopoverController.h" #import "MyOwnPopover.h" #import "ViewController.h" #import "AdressBar.h" @interface ViewController () @end @implementation ViewController @synthesize webPage = mWebView; - (void)viewDidLoad { [super viewDidLoad]; addressBar = [[AdressBar alloc] init]; addressBar.delegate = self; [edittext addTarget:self action:@selector(showPopoverAdressBar:forEvent:) forControlEvents:UIControlEventTouchUpInside]; NSURL *url = [NSURL URLWithString:@"http://www.google.lv"]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [mWebView setScalesPageToFit:YES]; [mWebView setDelegate:self]; [mWebView loadRequest:request]; } -(void)loadReceivedAddress:(NSURLRequest *)url{ NSLog(@"url= %@", url);//there url always is not null and mWebView should load it if(mWebView != nil){ [mWebView loadRequest:url]; }else{ NSLog(@"mWebView is null");//...but there it say's that it's null }} -(void)showPopoverAdressBar:(id)sender forEvent:(UIEvent*)event { AdressBar *popoverControllesr = [[AdressBar alloc]init]; popoverControllesr.view.frame = CGRectMake(0,0, 600, 45); popoverControllesr.view.backgroundColor = [UIColor whiteColor]; popoverController = [[mypopoverController alloc] initWithContentViewController:popoverControllesr]; popoverController.cornerRadius = 20; if(_titles!=NULL){ popoverController.titleText = _titles;}else{ popoverController.titleText = @"Loading..."; } popoverControllesr.address.text = absoluteString; popoverController.popoverBaseColor = [UIColor orangeColor]; popoverController.popoverGradient= YES; popoverController.arrowPosition = TSPopoverArrowPositionHorizontal; [popoverController showPopoverWithTouch:event]; } @end </code></pre> <p>This is AdressBar.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @protocol AddressbarDelegate &lt;NSObject&gt; @required -(void)loadSomethingFromAddressBar:(NSURLRequest*)request; @end @interface AdressBar : UIViewController{ IBOutlet UIButton *cancel; } @property (nonatomic, retain) IBOutlet UITextField *address; @property (nonatomic, retain) NSURLRequest *request; @property(nonatomic, weak) id &lt;AddressbarDelegate&gt; delegate; @end </code></pre> <p>This is AdressBar.m:</p> <pre><code>#import "AdressBar.h" #import "ViewController.h" @interface AdressBar () @end @implementation AdressBar @synthesize delegate = delegate; - (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 from its nib.
