Write a WebView that supports full screen in IOS

Write a WebView that supports full screen in IOS

In this way, write the Layout

A TitleView is used as the top search bar:

@ Implementation TitleView-(id) initWithFrame :( CGRect) frame {self = [super initWithFrame: frame]; if (self) {// Initialization code [self initTilte];} return self;}-(void) initTilte {UITextField * field = [[UITextField alloc] initWithFrame: CGRectMake (20, 10,230, 30)]; _ textField = field; _ textField. autoresizingMask = UIViewAutoresizingFlexibleWidth; // automatically adjusts its position so that its left and right distances remain unchanged with superview _ textField. enablesReturnKeyAutomatically = YES; // enable return to use _ textField during input. placeholder = @ "please input:"; // sets the value of hint _ textField. textAlignment = NSTextAlignmentLeft; // text to the left: _ textField. borderStyle = UITextBorderStyleNone; // no border _ textField. font = [UIFont systemFontOfSize: 18366f]; // set the font size _ textField. contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter; _ textField. contentverticalignment = UIControlContentVerticalAlignmentCenter; // these two enable the text to be centered and show _ textField. clearButtonMode = inputs; // when input, clear button UIImage * image = [[UIImage imageNamed: @ "text_field_bg.png"] stretchableImageWithLeftCapWidth: 20 topCapHeight: 0]; // stretchableImageWithLeftCapWidth makes the image stretch _ textField. delegate = self; // set proxy _ textField for textField. background = image; // set the background to textField. leftViewMode = UITextFieldViewModeAlways; [_ textField setText: @ "http://m.baidu.com"]; CGRect frame = [_ textField frame]; frame. size. width = 15; UIView * view1 = [[UIView alloc] initWithFrame: frame]; _ textField. leftView = view1; // set the distance between the text and textField on the left [self addSubview: _ textField]; UIButton * button = [UIButton buttonWithType: UIButtonTypeCustom]; // init a button that can customize the background [button setBackgroundImage: [[UIImage imageNamed: @ "cancel_but_bg.png"] Priority: 20 topCapHeight: 0] forState: UIControlStateNormal]; button. frame = CGRectMake (, 10, 49, 30); // set the background of the button, which has two statuses: normal and highlight.

Viewdidload of viewcontroller:

If you perform the full screen and exit full screen operation:

-(Void) scrollViewDidEndDragging :( UIScrollView *) scrollView willDecelerate :( BOOL) decelerate {CGFloat screenHeight = [UIScreen mainScreen]. applicationFrame. size. height; NSArray * arr = [self. customWidgetUiWebView subviews]; UIScrollView * sView = [arr objectAtIndex: 0]; if (sView. contentSize. height <screenHeight) {// if the content area of the webview is smaller than the screen height, return;} if (self. customWidgetUiWebView. widgetEmbedStat Us = ENoWidgetEmbed) {NSLog (@ "= y = % f", sView. contentOffset. y); if (sView. contentOffset. y> = SearchBar_Height & sView. contentOffset. y <sView. contentSize. height-screenHeight) {// contentOffset is the position of the origin of the currently displayed area relative to the origin of the entire scrollView. if it is greater than SearchBar_Height and less than the bottom if (isFullScreenMode) {return ;} else {[self goToFullScreenMode] ;}} else if (isFullScreenMode) {[self exitFullScreenMode] ;}}-(void) goT Detail {[UIView beginAnimations: @ "FullScreenMode" context: NULL]; [UIView setAnimationDuration: 0.5f]; [UIView attributes: self]; [UIView attributes: @ selector (animationDidStop: finished: context :)]; [UIView setAnimationBeginsFromCurrentState: YES]; [UIView setAnimationCurve: UIViewAnimationCurveEaseInOut]; _ webToolBarController. webToolBar. frame = [[WebToolBarUIManager SharedInstance] webToolBarHideFrame]; [UIView commitAnimations]; _ titleView. frame = [[CustomUiWebViewUIManager sharedInstance] getSearchBarViewFullView]; _ customWidgetUiWebView. frame = [[CustomUiWebViewUIManager sharedInstance] timeout]; // shwo button [UIView beginAnimations: @ "animationID" context: NULL]; [UIView setAnimationDuration: 0.5f]; _ fullScreenBtn. alpha = 1; [UIView c Response]; isFullScreenMode = YES; [_ titleView resignTextField];}-(void) Comment {[UIView beginAnimations: @ "NotScreenMode" context: NULL]; [UIView setAnimationDuration: 0.2f]; [UIView setAnimationDelegate: self]; [UIView setAnimationDidStopSelector: @ selector (animationDidStop: finished: context :)]; [UIView attributes: YES]; [UIView setAnimationCurve: UIViewAnimati OnCurveEaseInOut]; [SearchBarViewController sharedInstance]. view. frame = [[SearchBarUIManager sharedInstance] searchBarViewFrame]; _ webToolBarController. webToolBar. frame = [[WebToolBarUIManager sharedInstance] webToolBarFrame]; if (!

Gosafari code:

- (void)goSafari{UIActionSheet *actionSheet = [[UIActionSheet alloc]  initWithTitle:NSLocalizedString(@"String_QueryOpBySafari", nil)  delegate:self  cancelButtonTitle:NSLocalizedString(@"String_Cancel", nil)  destructiveButtonTitle:nil  otherButtonTitles:NSLocalizedString(@"String_OpBySafari", nil),nil];[actionSheet showInView:self.view];}- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{if (buttonIndex==0){if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:[_customWidgetUiWebView stringByEvaluatingJavaScriptFromString:@"document.URL"]]]){[[CCommon sharedInstance ]appOpenUrl:[_customWidgetUiWebView stringByEvaluatingJavaScriptFromString:@"document.URL"]];}else{[[CCommon sharedInstance ]appOpenUrl:[[_customWidgetUiWebView.request URL]absoluteString]];}                }}
