Got a Problem that my activity indicator does not show up anyone a idea?
ViewController.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController
{
IBOutlet UIWebView *webview;
IBOutlet UIActivityIndicatorView *active;
UIAlertView *alert_start;
}
ViewController.m
// Do any additional setup after loading the view, typically from a nib.
[webview loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"home-de" ofType:#"html"]isDirectory:NO]]];
- (void)webViewDidStartLoad:(UIWebView *) webview
{
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
[active startAnimating];
}
- (void)webViewDidFinishLoad:(UIWebView *) webview
{
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
[active stopAnimating];
}
- (IBAction)tele_button:(id)sender
{
//Local HTML Call Button
NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"phone" ofType:#"html"]isDirectory:NO]];
[self->webview loadRequest:theRequest];
}
- (IBAction)mail_button:(id)sender
{
//Mail App Mail Button
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"mailto://info#optibelt.com"]];
}
- (IBAction)web_button:(id)sender
{
//Local HTML Button
NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString: #"http://optibelt.com"]];
[self->webview loadRequest:theRequest];
}
- (IBAction)news_button:(id)sender
{
//local Home Button
NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"home-de" ofType:#"html"]isDirectory:NO]];
[self->webview loadRequest:theRequest];
}
The activity indicator is set as behavior animating (checked) and hides when stopped (checked)
Would be great if i get some help :)
You might want to check a couple of things. First, check to see if the activity indicator outlet is connected in IB. Second, check to see if the activity indicator is above the UIWebview. It could be that it is being covered up. You also might want to check that it isn't hidden in IB.
Good luck

I have a UITableView within a UINavigationController,when I select a cell in the table view,it should slide to a UIWebView
//code in table view delegate(tableviewcontroller)
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSURL *url = [NSURL URLWithString:#"https://www.baidu.com/"];
self.webViewController.title = #"UIWebViewTest";
self.webViewController.URL = url;
[self.navigationController
pushViewController:self.webViewController animated:YES];
}
self.webViewController was initialized by
- (void)viewDidLoad {
[super viewDidLoad];
//..
//other code
//..
YGGWebViewController *wvc = [self.storyboard
instantiateViewControllerWithIdentifier:#"wvc"];
self.webViewController = wvc;
}
in the YGGWebViewController, I have a NSURL *URL property and override the setter
- (void)setURL:(NSURL *)URL{
_URL = URL;
if (_URL) {
NSURLRequest *req = [NSURLRequest requestWithURL:_URL];
[self.webView loadRequest:req];
}
}
besides,YGGWebViewController also have a UIWebView *webView property linked to a UIWebView in storyboard.
what odd is the web view does not display anything when it slides to the screen in the first time,but it will show the website in the second time（go back to the table view by navigation bar,and select a cell again）.
Environment
xcode-7.0
deployment target-7.0
OS X Yosemite-10.10.5
P.S
if I move the code
if (_URL) {
NSURLRequest *req = [NSURLRequest requestWithURL:_URL];
[self.webView loadRequest:req];
}
to viewDidLoad in YGGWebViewController,it works right.but why?
Hi, I have a slight issue. I have tried all types of solutions I could find, minus the outdated codes, on this topic of getting a UIWebView link to pop open Safari and load it there.
So far I can get the specific size to load in simulator, but every time I click it, it loads right there. I have to be missing a major step or I have the AppDelegate .h .m and ViewController .h .m completely messed up.
I was big into coding for devices up to 3rd Gen iPod/iPhones. I know that Xcode likes to update a lot and I have the 5.0.2 version. I am basically a No0b again, since I have been out of the game for some time.
Please let me know if you have any tips. Besides to give it up. lol. I know it can be done. Here is what I have...
#import "WIAppDelegate.h"
#implementation WIAppDelegate
- (BOOL)webview:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request
navigationType:(UIWebViewNavigationType)navigationType {
// This practically disables web navigation from the webView.
if (navigationType == UIWebViewNavigationTypeLinkClicked) {
[[UIApplication sharedApplication] openURL:[request URL]];
return FALSE;
}
return TRUE;
}
#import <UIKit/UIKit.h>
#interface WIViewController : UIViewController
#property (strong, nonatomic) IBOutlet UIWebView *webview;
#end
#import "WIViewController.h"
#interface WIViewController ()
#end
#implementation WIViewController
- (void)viewDidLoad {
[super viewDidLoad];
NSString *fullURL = #"http://THESITE.com";
NSURL *url = [NSURL URLWithString:fullURL];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[_webview loadRequest:requestObj];
}
#end
You need to implement the webview:shouldStartLoadWithRequest:navigationType: method on the class that acts as the UIWebViewDelegate
This should most likely live in your WIViewController class
#implementation WIViewController
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *fullURL = #"http://THESITE.com";
NSURL *url = [NSURL URLWithString:fullURL];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[_webview loadRequest:requestObj];
_webview.delegate = self;
}
- (BOOL)webview:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
if (UIWebViewNavigationTypeLinkClicked == navigationType) {
[[UIApplication sharedApplication] openURL:[request URL]];
return NO;
}
return YES;
}
#end
You will also need to ensure that you actually set this class as the UIWebViewDelegate I've down this as the last line of the viewDidLoad but you could hook this up in the xib if you prefer
Hey guys, i'm trying to make the buttons on my project to open a different webview url. I'm new to iOS programming, but i've used andriod programming. Is this possible? I've a ready created another webview view that sits in the supporting files folder.
Here is my code below
Viewcontroller.m
#import "ViewController.h"
#implementation ViewController
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
-(void)viewDidLoad
{
NSString *urlString = #"http://www.athletic-profile.com/Application";
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlString];
//URL Requst Object
NSURLRequest *webRequest = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[webView loadRequest:webRequest];
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
}
- (void)viewDidDisappear:(BOOL)animated
{
[super viewDidDisappear:animated];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
#synthesize webView;
#end
Add a button to your View then give a connection to it. In the action method just write your code
-(IBAction*)yourButtonActionMethod:(id)sender
{
[UIWebView *aWebView =[[UIWebView alloc] initWithFrame:CGRectMake(x,y,width,height)];
aWebView.delegate=nil;
NSString *urlString = #"http://www.athletic-profile.com/Application";
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlString];
//URL Requst Object
NSURLRequest *webRequest = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[aWebView loadRequest:webRequest];
[self.view addSubView:aWebView];
}
Firstly you can drag & drop UIButton in First Class & create action of that Button then create a new class for UIWebView in which you want to open you url named your choice which is subclass of UIViewController then into your .Xib or Storyboard you just drag & drop the UIWebView then create outlet of UIWebView after you write this code in first class of that button's action :-
- (IBAction *) firstButton:(id) sender
{
NSString *urlString = #"http://www.athletic-profile.com/Application";
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlString];
//URL Request Object
NSURLRequest *webRequest = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[webView loadRequest:webRequest];
}
I am building a tab bar application with a different pdf in each tab. I have two sets of view controllers. Each have this relative code
#import "SecondViewController.h"
#interface SecondViewController ()
#end
#implementation SecondViewController
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:#"Winter_Newsletter"
ofType:#"pdf"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];
[webview setScalesPageToFit:YES];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
I keep receiving an error "undeclared identifier 'web view'" What am I doing Wrong?
You are showing in the code two versions of webView(capital V) and webview(small v)
[webView loadRequest:request];
[webview setScalesPageToFit:YES];
And if you are using auto-synthesize then it sould be
self.webView or _webView
And also, don't forget to make a property of the web view and control drag to hook it up!
How can I make a "Pull to refresh" in iOS 5 for an UIWebView ? I can't find a tutorial.
I have got a WebView in a Tab Bar application, and I want to refresh the WebView with a "Pull to refresh" like Twitter.
Where can I find a complete tutorial ?
Thank you
I cannot provide a tutorial, maybe I'll write one but I think it was quite simple,
I did this slightly modifying SPPullView.
Here you can grab the files (SPPullView.m and SPPullView.h).
Relevant code in the main UIViewController is something like:
- (void)viewDidLoad
{
[super viewDidLoad];
self.pullView = [[SPPullView alloc] initWithScrollView:self.webView.scrollView];
[self.pullView setDelegate:self];
[self.webView.scrollView addSubview:self.pullView];
[self.webView.scrollView setDelegate:self];
for (UIView *subview in [self.webView.scrollView subviews] ) {
subview.userInteractionEnabled = NO; // used to disable copy/paste, etc inside the webview
}
//[self doYourStuff];
}
//Called when the user pulls to refresh (this is when you should update your data)
- (void) pullViewShouldRefresh: (SPPullView *) view {
[self updateYourStuff];
}
You can also add some logic or properties to prevent the user zooming, or deactivate the pull view temporarily while zooming.
This works very well: http://blog.gomiso.com/2012/03/22/yet-another-pull-to-refresh-library/
I wrote this code and it is working fine. This may help you.
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *fullURL = URL you want to hit;
NSURL *url = [NSURL URLWithString:fullURL];
NSURLRequest *requestObject = [NSURLRequest requestWithURL:url];
webView.delegate = (id)self;
[webView loadRequest:requestObject];
UIRefreshControl *refreshControlOnPull = [[UIRefreshControl alloc] init];
[refreshControlOnPull addTarget:self action:#selector(handleRefresh:) forControlEvents:UIControlEventValueChanged];
[webView.scrollView refreshControlOnPull]; //<- this is point to use. Add "scrollView" property.
}
-(void)handleRefresh:(UIRefreshControl *)refresh {
// Reload my data
NSString *fullURL = The Url you want to hit;
NSURL *url = [NSURL URLWithString:fullURL];
NSURLRequest *requestObject = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObject];
[refresh endRefreshing];
}
