How to prevent UIwebView refreshing?

由 时光总嘲笑我的痴心妄想 提交于 2019-12-02 10:04:46
I have made an app that contains a lot of PDF files that are loaded in the UIwebview. Whenever I open the PDF, close it, and then go back to it, the file starts from the top again, it reloads. I don't want it to reload once the user goes out of the file and comes back to it. Example of my code is below. (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. NSString *path = [[NSBundle mainBundle] pathForResource:@"HnonC" ofType:@"pdf"]; NSURL *url = [NSURL fileURLWithPath:path]; NSURLRequest *request = [NSURLRequest requestWithURL:url]

Here is some HTML that I am working with in my UIWebView: <div id = "1"> <span style = "background-color:red"> <a href = "10&20"> This is a link </a> </span> </div> Once the link is tapped, I want to programmatically select the link text in the UIWebView (so "This is a link" would now be highlighted with the blue iOS text selection tool). This is why I am sending some range information in the href of the a tag. This is the call I am using to try and make this programmatic selection: //set content editable true [self.webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@

I have a UIWebView which loads a html string on viewDidLoad. It detects if the user clicks a link and display a modal view, but when i close the modal view the UIWebView's html has gone! If i use a FormSheet Modal Style the content stays behind, its only fullscreen modals that cause this. Obviously i can just input the html string again on viewWillAppear which fixes it but this causes makes the content flick back on which i don't want. heres my code: -(void)viewDidLoad { [self loadArticleText]; ... } -(void)loadArticleText { NSString *htmlHead = @"<html><head>..."; NSString *htmlFoot = @"<

UIWebView 横竖屏尺寸不正确问题解决

由 ぐ巨炮叔叔 提交于 2019-12-02 09:07:57
今天发现ios中，UIWebview 从横屏到竖屏出现界面尺寸不正确，从竖屏到横屏就没有问题。 经过google后，发现了一个比较好的解决方法。 在UIWebview加载的html页面中加入如下标签： <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=no;"/> content=width=device-width 是将页面尺寸设置成当前设备宽度，也可以手动设置成其他宽度。 user-scalable 是控制页面能否让用户进行缩放控制。 加上以上标签就可以解决横竖屏尺寸不正确的情况。 来源： oschina 链接： https://my.oschina.net/u/566401/blog/82082

setKeyboardAppearance for UIWebView

由 那年仲夏 提交于 2019-12-02 08:12:33
问题 It is well know that the keyboard appearance of UITextView and UITextField can be set as following : [self.textField setKeyboardAppearance:UIKeyboardAppearanceAlert]; But how could we set the keyboard appearance of a UIWebView ? Actually, here im using ckeditor for HMTL editing. 回答1: Unfortunately, you can not set the keyboard appearance for a UIWebView using Apple's UIKit APIs. You can however specify the input type using html tags like so: <input type="text" size="30" autocorrect="off"
