I'm using a small UIWebView, and scalesPageToFit doesn't work correctly for some url. (look like it cannot resize at 100%. (but if i zoom out the webview manually(gesture), it work!
view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200.0f, 400.0f)];
webViewT = [[UIWebView alloc] initWithFrame:view.bounds];
webViewT.delegate = self;
webViewT.scalesPageToFit = YES;
NSURL* url = [NSURL URLWithString:#"http://www.google.com/"];
[webViewT loadRequest:[NSURLRequest requestWithURL:url]];
Please note that i've found a solution:(below work, BUT I have the time to see a "resize"
- (void) webViewDidFinishLoad:(UIWebView *)webViewT {
if ([theWebView respondsToSelector:#selector(scrollView)])
{
UIScrollView *scroll=[theWebView scrollView];
float zoom=theWebView.bounds.size.width/scroll.contentSize.width;
[scroll setZoomScale:zoom animated:NO];
}
}
Any idea? Thanks!
In Some of cases this types of problem Generated. At that time java script use for control of Zoom of UIWebView, use following code.
NSString *jsCommand = [NSString stringWithFormat:#"document.body.style.zoom = 1.5;"];
[webLookupView stringByEvaluatingJavaScriptFromString:jsCommand];
Other way is
Refer this Answer UIWebView does not scale content to fit
So I basically get an NSData of UIImage and I use a UIWebView to display it. I do it that way:
[self.view addSubview:webView];
webView.delegate = self;
webView.scalesPageToFit = YES;
webView.backgroundColor = [UIColor darkGrayColor];
I then load the picture into it like this:
NSData *image02Data = attachmentToLoad.attachment_data;
[webView loadData:image02Data MIMEType:#"image/jpg" textEncodingName:nil baseURL:nil];
And I get a result that isn't exactly what I want:
As you can see the image leaves a white bottom line down at the bottom of the UIWebView. How can I make the size of the UIWebView to be equal to that of the image?
Have you seen this post?

I think it is exactly you want
I'm new to iphone app development and I'm trying to add an image to the start of my app. I've created an array of images which when iterated should create an animation.
-(void)viewDidLoad
{
animation = [[UIImageView alloc] init];
animation.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:#"panda1.png"],
[UIImage imageNamed:#"panda2.png"],
[UIImage imageNamed:#"panda3.png"], nil];
animation.animationRepeatCount = 2;
animation.animationDuration = 2;
[animation startAnimating];
[self.view addSubview:animation];
[animation release];
//for loading the webpage at start up
NSString *urlAddress = #"http://projects.seng.uvic.ca/fatpanda/m/most_recent.php";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
//load the request in the UIWebView
[webView loadRequest:requestObj];
}
The reason I release the animation at the end of this is because I'd like to remove the last image so I can replace it with a view of a website in a UIWebView and have that visible at the end. The code above compiles but when I run it no images appear but the website does.
Any help would be greatly appreciated.
try this, i think your frame is ending up all zeros.
UIImage * first = [UIImage imageNamed:#"panda1.png"]
animation = [[UIImageView alloc] initWithImage:first];
animation.animationImages = [NSArray arrayWithObjects:
first,
[UIImage imageNamed:#"panda2.png"],
[UIImage imageNamed:#"panda3.png"], nil];
Also...
releasing the animaiton will not remove it from the superview. in fact calling addSubview will increase the reference count to the UIImageView and releasing it is the correct thing to do. When you want to to remove from the view it you will have to find it again in the list of subviews and either hide it or call removeFromSuperview.
I want my webview with Rounded Rectangle Corners.
Any help ?
Here's how:
//first, you
#import <QuartzCore/QuartzCore.h>
//.....
//In your method, where you add your UIWebView, do:
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(50, 220, 200, 100)];
//The rounded corner part:
webView.layer.cornerRadius = 5;
webView.clipsToBounds = YES;
//Load a web site:
[webView loadRequest: [NSURLRequest requestWithURL:
[NSURL URLWithString:#"http://www.stackoverflow.com/"]]];
//yourView is the UIView's superview, might be the window, or anything you want
[yourView addSubview: webView];
[webView release];
This uses the QuartzCore framework, and it only works on >= OS 3.0
you can add some mask image over your webView. in such way you can change form of the visible part of your webView
we're trying to implement an article detail view for an RSS-like application. The windows has a UIScrollView that contains a UITextView (which is the title), a UIButton (which opens a gallery), and a UIWebView (with the body). The idea is that all these elements scroll together...
The problem is that whenever we have a body over 1000px tall, everything below that mark is truncated. We've heard that this is because that is the maximum height for a view, and since the Scroll is handled by the top UIScrollView, there is no way to see what's further down.
does anybody know a way around this?
Thanks!
---- update 1 ----
We've broken up the body into 900px-high chunks, but all webviews after the first one show no content...
UIScrollView *scroll=[[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
[scroll setBackgroundColor:[UIColor whiteColor]];
[scroll setCanCancelContentTouches:NO];
scroll.clipsToBounds = NO;
scroll.indicatorStyle = UIScrollViewIndicatorStyleBlack;
//TÃtulo
CGRect tit =CGRectMake(5.0f, 0.0f, 315.f, 50.0f);
UILabel *titulo=[[UILabel alloc] initWithFrame:tit];
titulo.text=[itemNew objectForKey:#"titulo"];
titulo.numberOfLines = 2;
titulo.font=[UIFont fontWithName:#"Helvetica" size:16.0f];
titulo.textColor=[self getColor:#"00336E"];
[scroll addSubview:titulo];
[titulo release];
//Entradilla
float altura_entradilla=calcLabel([itemNew objectForKey:#"entradilla"], [UIFont boldSystemFontOfSize:16], 50, 315.0f);
CGRect ent_frame = CGRectMake(5.0f, 50.0f, 315.0f,altura_entradilla );
UILabel *entradilla=[[UILabel alloc] initWithFrame:ent_frame];
entradilla.text=[itemNew objectForKey:#"entradilla"];
entradilla.numberOfLines=4;
entradilla.font=[UIFont fontWithName:#"Helvetica" size:17.0f];
entradilla.textColor=[UIColor blackColor];
[scroll addSubview:entradilla];
[entradilla release];
NSString *cuerpo=[itemNew objectForKey:#"cuerpo"];
[scroll setContentSize:CGSizeMake(320.0f,40000.0f)];
[scroll setScrollEnabled:YES];
webView = [[UIWebView alloc] initWithFrame:CGRectMake(5.0f, altura_entradilla+50, 315.0f, 900)];
[webView loadHTMLString:cuerpo baseURL: [NSURL fileURLWithPath:[[NSBundle mainBundle] resourcePath]]];
webView.detectsPhoneNumbers=NO;
webView.delegate=self;
[webView setScalesPageToFit:NO];
[scroll addSubview:webView];
webView.backgroundColor=[UIColor blackColor];
webView.userInteractionEnabled=NO;
[webView release];
if (altura_webview>900) {
UIWebView *webView2 = [[UIWebView alloc] initWithFrame:CGRectMake(5.0f, altura_entradilla+50+900, 315.0f, 900)];
[webView2 loadHTMLString:cuerpo baseURL: [NSURL fileURLWithPath:[[NSBundle mainBundle] resourcePath]]];
webView2.detectsPhoneNumbers=NO;
webView2.delegate=self;
[webView2 setScalesPageToFit:NO];
[scroll addSubview:webView2];
webView2.backgroundColor=[UIColor yellowColor];
webView2.userInteractionEnabled=NO;
[webView2 release];
}
self.view=scroll;
check the contentSize on your UIScrollview.
I've not heard of a 1000 point limit (or seen it in bigger views I have in our app).
Use more then one UIWebViews as body
Are you using loadHTMLString to add content to webView?
Try loadRequest method. There is no problem with 1024px when you are using loadRequest
I had the same problem and I read and tried a few tips of this thread, but neither loading the content via loadHTMLString, nor using [_webView setNeedsDisplay] did changed anything for me. (I should try loading more UIWebViews, but I'm lazy:)
I used a quick and dirty fix using the scrollview delegate, which did the trick:
#interface ArticleViewController : UIViewController <UIScrollViewDelegate>
then fire up the view in init
_scrollView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
self.view = _scrollView;
_scrollView.delegate = self;
and use the delgate's method to redraw the webView as it shows up
- (void) scrollViewDidEndDragging: (UIScrollView *) scrollView willDecelerate: (BOOL) willDecelerate
{
CGRect frame = _webView.frame;
frame.size = CGSizeMake(frame.size.width, frame.size.height + 1);
_webView.frame = frame;
}
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
CGRect frame = _webView.frame;
frame.size = CGSizeMake(frame.size.width, frame.size.height + 1);
_webView.frame = frame;
}
When you say :
We've tried breaking the body into several 900px-high webViews, but the second, third, etc. get blanked out (you can see the backgroundColor, but not the content)...
It seems to me that other persons have met this issue (I can't find the posts again), in fact UIWebviews seems to use only one HTML Interpreter. Meaning that if one UIWebView is loading HTML Content, others UIWebView won't load anything.
To solve that, you need to use UIWebView's delegate methods : didFinishLoad, and start loading the other webviews after that.
Please be aware that I'm not sure about what I'm saying, because I did not try it myself, but it might be a solution.
The post marked as the answer has a link in it's last comment. That is the solution to this problem. I had this very same problem, and invoking [[webView _documentView] _webCoreNeedsDisplay]; in those 2 delegates solved it. Cheers.
