내 앱에서 ePub를 읽으려면 AePubreader 샘플 코드를 사용하고 있습니다. 내가 직면 한 문제는 장의 마지막 페이지가 제대로 렌더링되지 않고 보이는 영역을 벗어나는 것입니다. 나는 ipad에서 2 페이지 모드로 변환하기 위해 다음과 같이 AePubreader 코드를 편집했다.두 페이지 모드로 ePub 렌더링
-In chaper.m의 파일 webViewDiDFinishLoading이 다음 한 코드를 다음과 같이 EpubViewController.m webViewDidFinishLoading에서
- (void) webViewDidFinishLoad:(UIWebView*)webView{
NSString *varMySheet = @"var mySheet = document.styleSheets[0];";
NSString *addCSSRule = @"function addCSSRule(selector, newRule) {"
"if (mySheet.addRule) {"
"mySheet.addRule(selector, newRule);" // For Internet Explorer
"} else {"
"ruleIndex = mySheet.cssRules.length;"
"mySheet.insertRule(selector + '{' + newRule + ';}', ruleIndex);" // For Firefox, Chrome, etc.
"}"
"}";
NSString *insertRule1 = [NSString stringWithFormat:@"addCSSRule('html', 'padding-left: 0px;padding-right: 0px; padding-top: 0px; padding-bottom: 0px; height: %fpx;-webkit-column-count: 2; -webkit-column-gap: 0px; ')", webView.frame.size.height];
NSString *insertRule2 = [NSString stringWithFormat:@"addCSSRule('p', 'text-align: justify;')"];
NSString *setTextSizeRule = [NSString stringWithFormat:@"addCSSRule('body', '-webkit-text-size-adjust: %d%%;')",fontPercentSize];
NSString *setImageRule = [NSString stringWithFormat:@"addCSSRule('img', 'max-width: %fpx; height:%fpx;')", webView.frame.size.width-200,webView.frame.size.height-200];
NSString *setFontRule = [NSString stringWithFormat:@"addCSSRule('body', 'font-family: Arial;' , 'font-name: Arial-BoldItalicMT;')"];
[webView stringByEvaluatingJavaScriptFromString:setFontRule];
[webView stringByEvaluatingJavaScriptFromString:setImageRule];
[webView stringByEvaluatingJavaScriptFromString:varMySheet];
[webView stringByEvaluatingJavaScriptFromString:addCSSRule];
[webView stringByEvaluatingJavaScriptFromString:insertRule1];
[webView stringByEvaluatingJavaScriptFromString:insertRule2];
[webView stringByEvaluatingJavaScriptFromString:setTextSizeRule];
float totalWidth = [[webView stringByEvaluatingJavaScriptFromString:@"document.body.scrollWidth"] floatValue];
pageCount = (ceilf)((float)totalWidth/webView.frame.size.width);
NSLog(@"Chapter %d: %@ -> %d pages & totalWidth :: %f", chapterIndex, title, pageCount,totalWidth);
[webView dealloc];
[delegate chapterDidFinishLoad:self];
}
은 다음과 같습니다 -
- (void)webViewDidFinishLoad:(UIWebView *)theWebView{

float pageCountofChapter = [[loadedEpub.spineArray objectAtIndex:currentSpineIndex] pageCount];
pagesInCurrentSpineCount =(ceilf)(pageCountofChapter/2.0);
UIScrollView* sv = nil;
for (UIView* v in webView.subviews) {
if([v isKindOfClass:[UIScrollView class]])
{
sv = (UIScrollView*) v;
sv.contentSize = CGSizeMake(pagesInCurrentSpineCount*1024, sv.contentSize.height);
}
}
// NSLog(@"TotalWidth :: %d && pagesInCurrentSpineCount :: %d && currentPageInSpineIndex :: %d",totalWidth,pagesInCurrentSpineCount,currentPageInSpineIndex);
[self gotoPageInCurrentSpine:currentPageInSpineIndex];
}
내가 발견 한 그 계산 된 페이지에있을 때 홀수 번째 장의 마지막 페이지가 제대로 렌더링되지 않습니다? 또한, epub을 정확하게 렌더링하기 위해 두 페이지 모드 지원을 제공하는 대체 라이브러리가 있습니까?
감사합니다.이 메소드에서 수행하는 작업은 무엇입니까? UIScrollView * scrollV = [ self getScrollViewFromWebView : webView]; – dineshprasanna
