我加載一個HTML文件在UIWebview.I我試圖調整UIWebview中的圖像大小加載。在此web視圖中,根據設備大小將html內容拆分爲多個頁面(下面的代碼顯示)。對於我使用的滑動手勢分頁。它正常工作,直到this.In這個html文件我有幾個圖像的大小互不相同。有些圖像不僅僅是設備的寬度。我需要修正圖像的寬度,使其適合屏幕。我不想滾動webview,因爲我使用了滑動手勢進行分頁。那麼,如何根據設備寬度重新調整圖像的大小。如何在UIWebview中調整圖像大小?
我用下面的代碼
- (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: 0px; height: %fpx; -webkit-column-gap: 0px; -webkit-column-width: %fpx;')", webview4epub.frame.size.height, webview4epub.frame.size.width];
NSString *insertRule2 = [NSString stringWithFormat:@"addCSSRule('p', 'text-align: justify;')"];
[webview4epub stringByEvaluatingJavaScriptFromString:varMySheet];
[webview4epub stringByEvaluatingJavaScriptFromString:addCSSRule];
[webview4epub stringByEvaluatingJavaScriptFromString:insertRule1];
[webview4epub stringByEvaluatingJavaScriptFromString:insertRule2];
NSString* foundHits = [webview4epub stringByEvaluatingJavaScriptFromString:@"results"];
NSMutableArray* objects = [[NSMutableArray alloc] init];
NSArray* stringObjects = [foundHits componentsSeparatedByString:@";"];
for(int i=0; i<[stringObjects count]; i++){
NSArray* strObj = [[stringObjects objectAtIndex:i] componentsSeparatedByString:@","];
if([strObj count]==3){
[objects addObject:strObj];
}
}
int totalWidth = [[webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.scrollWidth"] intValue];
}
