用UIWebView加载本地图片和gif图
加载gif图：
NSData *gif = [NSData dataWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"9" ofType:@"gif"]];
// view生成
[webView loadData:gif MIMEType:@"image/gif" textEncodingName:NULL baseURL:NULL];
加载本地的图片:
//加载本地的图片原理是使用webView加载html标签
UIImage *selectedImage = [UIImage imageNamed:@"icon_VC6_boxStart"];
NSString *stringImage = [self htmlForJPGImage:selectedImage];
//构造内容
NSString *contentImg = [NSString stringWithFormat:@"%@", stringImage];
NSString *content =[NSString stringWithFormat:
@"<html>\n"
"<style type=\"text/css\">\n"
"<!--\n"
"body{font-size:40pt;line-height:60pt;}\n"
"-->\n"
"</style>\n"
"<body>\n"
"%@\n"
"</body>\n"
"</html>"
, contentImg];
//让self.contentWebView加载content
[webView loadHTMLString:content baseURL:nil];
//编码图片
- (NSString *)htmlForJPGImage:(UIImage *)image
{
NSData *imageData = UIImageJPEGRepresentation(image,1.0);
NSString *str1=[NSString stringWithFormat:@"data:image/jpg;base64,%@",[imageData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed]];
return [NSString stringWithFormat:@"<img src = \"%@\" />", str1];
}
