I need that my UIWebView shows me an entire web page, from the top to the bottom (it doesn't matter if the page is very long and I don't care if I'm not able to read it, I just want to see ALL the page).
So, how do I vertically fit the page in the web view?
Scales to fill, Aspect fit etc... don't work.
Thanks.
You can do it simply by using the following line of code:
myWebView.scalesPageToFit = YES;
This will scale the page to adjust both horizontally and vertically within your UIWebView.
You can sacle with javascript function
NSString *jsCommand = [NSString stringWithFormat:#"document.body.style.zoom = 1.5;"];
[myWebView stringByEvaluatingJavaScriptFromString:jsCommand];
[webview setScalesPageToFit:YES];
or
[webview sizeToFit];
setScalesPageToFit: gives output like this
Sometimes myWebView.scalesPageToFit = YES; doesn't work so we have to set it that's why I written [myWebView setscalesPageToFit:YES]; I have faced this type of problem in UIButton that button.text = #"long text"; does not work but when I use [button setTitle:#"long text" forControlState:UIcontrolStateNormal]; it worked. So may be it will work for you

I am using a web view its working fine. but I am having a three issue 1.i want to change the font 2. change the size of font 3. when I scroll the web content to bottom it's not scrolling up to the bottom.
content=[[UIWebView alloc]init];
content.Frame=CGRectMake(10, 200, 300, 480);
[content loadHTMLString:content1 baseURL:nil];
[content loadHTMLString:[NSString stringWithFormat:#"<html><body background-colo r: transparent text=\"#eadfa8\" font-family=\"Arial Rounded MT Bold\" font-size=\".1\">%#</body></html>", [self.JSONData objectForKey:#"content"]] baseURL: nil];
[content stringByEvaluatingJavaScriptFromString: #"content.body.style.fontFamily = 'Arial'"];
content.opaque=YES;
[self.view addSubview:content];
[content setBackgroundColor:[UIColor clearColor]];
[content setOpaque:NO];
above html coding I try to change the font family to Arial but its not working. help me .
For First two issues answer is Font change inside UIWebView
The third issue you can overcome by below lines
content.scalesPageToFit=TRUE;
content.scrollView.bounces = NO;
I am trying to view the web-page in UIWebView in iOS. Below is the link I am trying to view.
http://almaktab.com/forms/flight.html
The problem is width of table is 255px and when I open this in webview, it covers only half screen which looks odd. Below is the code I am using for viewing web page in UIWebView.
-(void)openWebPage:(NSString*)address {
NSURL*url=[NSURL URLWithString:address];
NSURLRequest*request=[NSURLRequest requestWithURL:url];
myWebView.scalesPageToFit = YES;
myWebView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
myWebView.contentMode = UIViewContentModeScaleAspectFit;
myWebView.autoresizesSubviews = YES;
[myWebView loadRequest:request];
[myWebView setAutoresizingMask:(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth)];
}
I want to stretch this webview so that form can fit for whole page.
I know solution for this would be width=100%, but client don't want to do any changes in their website now. Client asked to do changes in iOS only.
Any idea how this can be get done.
Screenshot (myWebView.scalesPageToFit = YES;)
Screenshot (myWebView.scalesPageToFit = NO;)
Try:
webView.scalesPageToFit = NO;
And in webViewDidFinishLoad:
[view stringByEvaluatingJavaScriptFromString:#"document.getElementById('table3').width='100%'"];
You should have not use AutoresizingMask.
I tried every permutation known to mankind and I cannot get a UIWebView to size properly in a modal form view for the iPad. The web page still displays the full iPad portrait width of 768 points.
Where and how do I tell UIWebView to display width 540 points?
I thought 'scalesPageToFit' is supposed to do this but it does not work.
I tried setting the web view to the size of form view which is 540 x 576 with navigation and status bar. Height is irrelevant though.
I tried adding a UIWebView to a UIView in a storyboard with all resizing set. I then removed the UIWebView and added it programmatically.
- (void)viewDidLoad
{
[super viewDidLoad];
CGRect aFrame = self.view.frame;
if (IS_IPAD)
{
aFrame = CGRectMake(0, 0, FORM_VIEW_WIDTH, FORM_VIEW_HEIGHT);
}
_webView = [[UIWebView alloc] initWithFrame:aFrame];
[_webView setOpaque:NO];
[_webView setDelegate:self];
[_webView setScalesPageToFit:YES];
self.view = _webView;
...
}
I also tried loading in viewDidAppear (in addition to viewDidLoad, viewWillAppear, etc.)
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[[self webView] setFrame:CGRectMake(0, 0, FORM_VIEW_WIDTH, FORM_VIEW_HEIGHT)];
[[self webView] setScalesPageToFit:YES];
NSURL *webURL = [NSURL URLWithString:#"http://www.google.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:webURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:5.0f];
[[self webView] loadRequest:request];
}
Any recommendations appreciated.
This keeps happening to me. I post a lengthy question, then two seconds later I find the answer.
Anyway, someone posted a solution to this problem here:
UIWebView -- load external website, programmatically set initial zoom scale, and allow user to zoom afterwards
However, I altered the script to set the width to the iPad width:
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
NSString* js =
#"var meta = document.createElement('meta'); "
#"meta.setAttribute( 'name', 'viewport' ); "
#"meta.setAttribute( 'content', 'width = 540px, initial-scale = 1.0, user-scalable = yes' ); "
#"document.getElementsByTagName('head')[0].appendChild(meta)";
[[self webView] stringByEvaluatingJavaScriptFromString: js];
}
Note the portion 'width = 540px, initial-scale = 1.0, user-scalable = yes'
I changed the width to the form width and scale to 1.0.
I also need to handle iPhone, and so I will make adjustments for that next. I think this fix may only be needed for the iPad form view.
UPDATE: Answer is short-lived. If I load any other page the sizing is thrown off again. Back to square one.
SOLUTION: This view will only need to access a few web pages that I developed. Therefore, I updated the few web pages that I need to access by adding the meta tag to each of them. I only need to access these pages and so this is the solution I plan to go with. This means I need to set the viewport width to 540px only for iPad somehow. I will figure that out next.
<meta name="viewport" content="width:540, initial-scale=1, maximum-scale=1">
This piece of code dispalys a document in a scrollable UIWebView:
- (void)viewDidLoad
{
[super viewDidLoad];
_myWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 760)];
NSURL *myUrl = [NSURL URLWithString:#"http://pathToDoc/myDoc.doc"];
NSURLRequest *myRequest = [NSURLRequest requestWithURL:myUrl];
[_myWebView loadRequest:myRequest];
[self.view addSubview:_myWebView];
}
This works fine except when trying to display a landscape document which has been created with custom margins which are smaller than standard.
The result is the contents of the right-hand edge of the document are chopped off.
Is there any way to display the whole document?
Well, after several months of frustration with this (can barely believe how long it took!), it turned out to need only a single line of code to solve the problem.
_documentWebView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
Add that just after the last line and suddenly all is well in the world.
I use a UIWebView in my app to present content, but now I can't do it anymore because I also need to use a UIScrollView and it creates conflicts related to scrolling.
Also, UIWebView is very slow.
So my question is : is there any another way to load string which contains HTML tags (strong, p, div, and etc...)?
UPDATE (improved explanation)
I have UIVIewController containing an image at the top, and under this image is a title and under the title is content (HTML string from web). The problem is that when the text is too big, the webview is scrolling, but not the whole page. I want the whole page to scroll, not just the webview.
You won't get anything faster or better than the native UIWebView. Probably you should overthink your UI/UX. What exactly do you want to achieve with a webview in a scrollview??
Perhaps attributed strings are enough for you. Look it up.
The OHAttributedLabel even parses HTML for you.
Solved.
-(void)webViewDidFinishLoad:(UIWebView *)webView {
NSString *output = [webView stringByEvaluatingJavaScriptFromString:#"document.body.scrollHeight;"];
int webViewHeight = [output intValue];
//NSLog(#"height: %d", webViewHeight);
if(webViewHeight > 220){
CGRect frame = articleContentWebView.frame;
frame.size.height = webViewHeight;
articleContentWebView.frame = frame;
int scrollViewheight = 416 + (webViewHeight - 220);
[articleScrollView setContentSize:CGSizeMake(320, scrollViewheight)];
}
}
In delegate method webViewDidFinishLoad I calculate height od UIWebView content and then set height of UIWebVIew and height of UIScrollView.
