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
#import <UIKit/UIKit.h>
#import "AdressBar.h"
#import "mypopoverController.h"
#interface ViewController : UIViewController<AddressbarDelegate>
{
UIWebView* mWebView;
mypopoverController *popoverController;
}
#property (nonatomic, retain) IBOutlet UIWebView* webPage;
#end
This is ViewController.m:
#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
This is AdressBar.h
#import <UIKit/UIKit.h>

Answer 1

Make sure that your web view Outlet & Delegate is correctly conncted.
There no space between URL Address because I also face the same issue. Try to open that url in web-Browser.

Answer 2

If this is your view hierarchy
---- In ViewController
---- Showing AddressBar View in POPOver
---- Remove POPover and display ViewController's web view
I suggest create a custom delegate method in AddressBar and when you remove the popOver trigger the delegate method. Implement the delegate in your ViewContrller and call loadSomethingFromAddressBar in that implemented delegate method
Note : make sure you have connected you webpage IBOutlet to your nib file.
// In Adressbar.h
#protocol AddressbarDelegate <NSObject>
#required
-(void)loadYourWebViewNow:(NSURLRequest*)request;
#end
#interface Addressbar : UIViewController
{
}
#property(nonatomic, weak) id <AddressbarDelegate>
// In Adressbar.m
- (void)loadAddresss {
NSString* urlString = _address.text; //geting text from UItextField
NSURL* url = [NSURL URLWithString:urlString];
if(!url.scheme)
{
NSString* modifiedURLString = [NSString stringWithFormat:#"http://%#", urlString];
url = [NSURL URLWithString:modifiedURLString];
}
NSURLRequest *request = [NSURLRequest requestWithURL:url];
if (request!=nil) {
NSLog(#"request is good");
if(_delegate!=nil)
{
[_delegate loadYourWebViewNow:request];
}
}
// In your ViewController.h
#interface ViewController : UIViewController<AddressbarDelegate>
{
//AdressBar *addressBar;
}
// In your ViewController.m implement the delegate method and set the delegate
#implementation ViewController
-(void)viewDidLoad
{
Remove these two below lines on viewDidLoad
//addressBar = [[Adressbar alloc] init];
//addressbar.delegate = self;
}
-(void)loadYourWebViewNow:(NSURLRequest*)request
{
[self loadSomethingFromAddressBar:request];
}
-(void)showPopoverAdressBar:(id)sender forEvent:(UIEvent*)event
{
AdressBar *popoverControllesr = [[AdressBar alloc]init];
popoverControllesr.delegate = self; // set the delegate here to this object.
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];
}
