How to get zoom in UIWebView.
I loaded pdf file from resource bundle in a UIWebView.
Now trying to zoom the webview. so its will get zooming effect to the pdf file.
So.
How can i zoom the UIWebView.
Any sample example. Please help me out.
Just use the following code:
self.pdfviewwebview.scalesPageToFit = YES;
self.pdfviewwebview.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
self.pdfviewwebview.delegate = self;
The most tricky thing here which most people forget is to set the webview's delegate,so take care about that.
UIWebView *tempWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.bounds.size.width, self.view.bounds.size.height)];
tempWebView.backgroundColor = [UIColor whiteColor];
**tempWebView.scalesPageToFit = YES; //this enables the zooming**
tempWebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
tempWebView.delegate = self;
[self.view addSubview:tempWebView];
[self setWebView:tempWebView];
NSString *path = [[NSBundle mainBundle] pathForResource:#"your_file" ofType:#"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
[self.webView loadRequest:request];
A pinch-to-zoom gesture can be simulated by holding down the Option key. On your simulator, two grey circles will appear indicating that its simulating a multi-touch, pinch-to-zoom gesture.

Error 9802 is a "Fatal Alert" according to the Apple's docs. I have looked at Google and SO and found nothing referencing 9802 that fixes this problem. I can change my code to go for "apple.com" and I get the page, but using my own URL, I get the error above. I have tried everything that I can think of, and nothing works. Time to ask for help! :D
The result of using
/usr/bin/nscurl --ats-diagnostics https://pragerphoneapps.com
is all tests fail (results are uploaded here)
This is an image of my app's .plist file (only pertinent part)
and this is an image of the target info:
And this is my code:
- (IBAction)showHTMLHelp:(UIButton *)sender {
// make the popover
UIViewController* popoverContent = [UIViewController new];
UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 450, 500)];
popoverView.backgroundColor = [UIColor colorWithWhite:(CGFloat)1.0 alpha:(CGFloat)1.0]; // frame color?
popoverContent.view = popoverView;
//resize the popover view shown in the current view to the view's size
popoverContent.preferredContentSize = CGSizeMake(450, 500);
NSString *urlAddress = #"https://pragerphoneapps.com"; // #"https://www.pragerphoneapps.com/bookstore-inventory-manager/upload-help/";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
// add the UIWebView for RichText
UIWebView *webView = [[UIWebView alloc] initWithFrame: popoverView.frame];
webView.backgroundColor = [UIColor whiteColor]; // change background color here
// add the webView to the popover
[webView loadRequest:requestObj];
[popoverView addSubview:webView];
// if previous popoverController is still visible... dismiss it
if ([popoverController isPopoverVisible]) {
[popoverController dismissPopoverAnimated:YES];
}
//create a popover controller
popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
[popoverController presentPopoverFromRect:((UIButton *)oShowHelp).frame inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
I seriously recommend you to fix your SSL certificate.
ATS requires you to have a valid SSL certificate, TLS version 1.2 or above and support for forward secrecy.
This will be a requirement at the beginning of 2017 so better get ready.
Anyway, meanwhile try the following steps to get this working.
Put this on top of your file:
#interface NSURLRequest (InvalidSSLCertificate)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString*)host;
+ (void)setAllowsAnyHTTPSCertificate:(BOOL)allow forHost:(NSString*)host;
#end
Disable App Transport Security in Info.plist.
Allow invalid SSL certificates before loading request:
[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[url host]];
Sample code that successfully loads your site:
NSString *urlAddress = #"https://pragerphoneapps.com"; // #"https://www.pragerphoneapps.com/bookstore-inventory-manager/upload-help/";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[url host]];
UIWebView *webView = [[UIWebView alloc] initWithFrame: self.view.frame];
webView.backgroundColor = [UIColor whiteColor];
[self.view addSubview:webView];
[webView loadRequest:requestObj];
I wonder why it can't work for setting "NSAllowArbitraryLoads to YES".If there are caches, try to reboot your Mac or Xcode.
And your "Exception Domains" settings have the wrong format.
I'm looking to package a .pdf file with my app so that users can view it on one of the app's tabbed UIViews. Most of the posts I've read explain how to display a .pdf that must be downloaded first from the internet. My question is: how do you access a .pdf that is packaged with the app and display it on a UI(Web)View (with no internet access/download required)?
EDIT: This snippet was the key (where "ReadFile.pdf" was .pdf added to the project):
NSString *urlAddress = [[NSBundle mainBundle] pathForResource:#"ReadFile" ofType:#"pdf"];
This is what you should do:
– (void) displayLocalPdfInWebView
{
CGRect rect = [[UIScreen mainScreen] bounds];
CGSize screenSize = rect.size;
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0,0,screenSize.width,screenSize.height)];
webView.autoresizesSubviews = YES;
webView.autoresizingMask=(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth);
NSString *urlAddress = [[NSBundle mainBundle] pathForResource:#"JaapSahib-Gurmukhi" ofType:#"pdf"];
NSURL *url = [NSURL fileURLWithPath:urlAddress];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
[webView loadRequest:urlRequest];
[window addSubview:webView];
[webView release];
}
Source: http://www.developerfeed.com/how-display-local-pdf-file-ios-uiwebview/
What this will essentially do is:
Create a CGRect to set the screen bounds
Allow autoresizing
Set the UIWebView to to a resource
Load the file into the UIWebView
Comment, and tell me how it goes!
In my application , I have a tttattributedlabel detect link and open in web view . if I set uitapgesture on this attributed label then gesture is always fire .
link is not working in any case if tap gesture set on attributed label .
You can try with it.
NSString *pathStr=#"http://stackoverflow.com/questions/29427320/override-tap-gesture-in-tttaributredlabel-link?noredirect=1#comment47025717_29427320";
if ([pathStr hasPrefix:#"http"]) {
UIWebView *myWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
myWebView.autoresizesSubviews = YES;
myWebView.autoresizingMask=(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth);
NSURL *myUrl = [NSURL URLWithString:pathStr];
NSMutableURLRequest *myRequest = [NSMutableURLRequest requestWithURL:myUrl];
[myWebView loadRequest:myRequest];
myWebView.delegate=self;
[self.view addSubview: myWebView];
}
i got a webview and i would like to capture an input from a webview HTML form. i have tried but i cant can some one help me please
this is my webview code
// Init Web View
UIWebView *webView;
webView = [[UIWebView alloc] initWithFrame:boundsRect];
webView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
webView.scalesPageToFit = YES;
webView.contentMode = UIViewContentModeCenter;
webView.multipleTouchEnabled = NO;
webView.userInteractionEnabled = YES;
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:url]]];
[self addSubview:webView];
[webView release];
return self;
To get value from webView, i used below code.
NSString* value = [webView stringByEvaluatingJavaScriptFromString:#"document.getElementById('text').value"];
NSLog(#"got: %#",value);
You could look into how phonegap http://phonegap.com/ solves this.
I have an UIWebView with and using QuartzCore to add some style to this. But when i'm execute:
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 10, self.view.bounds.size.width-20.0, self.view.bounds.size.height-30.0)];
NSString *urlAddress = #"http://www.google.com/";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
webView.layer.cornerRadius = 10;
webView.layer.borderColor = [UIColor whiteColor].CGColor;
webView.layer.borderWidth = 3.0f;
[self.view addSubview:webView];
I get an rounder View but content is sharp. There is a way to roundend corners in content in WebView
The content view is actually the scrollView of UIWebView, so
webView.scrollView.layer.cornerRadius = 10;
Agreed with #graver Answer but not completely Coz His working will not work on iphone 3g and iPod 2nd generation .
webView.layer.cornerRadius = 10;
[webView setClipsToBounds:YES];
ClipsToBound will simple resize all the subviews under webView.
