解除全屏模式后，UIWebView将被清除 [英] UIWebView gets cleared after dismissing a fullscreen modal
问题描述
我有一个UIWebView，它在viewDidLoad上加载一个html字符串。它检测用户是否单击链接并显示模态视图，但是当我关闭模态视图时，UIWebView的html已经消失了！如果我使用FormSheet模式样式，内容会留下，它唯一的全屏模式会导致这种情况。显然我可以在viewWillAppear上再次输入html字符串来修复它，但是这会导致内容重新回到我不想要的状态。继承我的代码：
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 = @"</body></html>";
NSString *htmlContent = [self.articleData valueForKey:@"fulltext"];
NSString *html = [[NSString alloc] initWithFormat:@"%@%@%@", htmlHead, htmlContent, htmlFoot];
[self.articleView loadHTMLString:html baseURL:nil];
[html release];
}
- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {
if (navigationType == UIWebViewNavigationTypeLinkClicked) {
NSURL *URL = [request URL];
ImageViewer *imageView = [[[ImageViewer alloc] initWithNibName:@"ImageViewer" bundle:nil] autorelease];
imageView.imageURL = URL;
[self presentModalViewController:imageView animated:YES];
return NO;
} else {
return YES;
}
}
如果我改变'return NO; 'to'返回YES;'webView内容保持不变，但显然它会加载图像。
If i change 'return NO;' to 'return YES;' the webView contents stays, like it should, but obviously it loads the image.
任何帮助？
谢谢
推荐答案
[self presentModalViewController：ImageView animated：YES] ;
[self presentModalViewController:ImageView animated:YES];
看起来你正在进行类调用而不是ImageView上的实例调用。
It looks like you are making a class call rather than an instance call on ImageView.
