UIWebview-加载PNG图像-错误

Question

I am trying to load the image(png) in UIWebview. 我正在尝试在UIWebview中加载image（png）。 But I got the following error ""ImageIO: PNGinvalid literal/lengths set" 但是我收到以下错误““ ImageIO：PNGinvalidliteral / lengths set”

I will get the "png" from the web service. 我将从网络服务中获取“ png”。 I will store it in the following path. 我将其存储在以下路径中。 "Users/XXX/Library/Application Support/iPhone Simulator/4.3.2/Applications/E4DE3097-EA84-492F-A2A7-5882202F3B00/Documents/attachement.png " “用户/ XXX /库/应用程序支持/ iPhone模拟器/4.3.2/Applications/E4DE3097-EA84-492F-A2A7-5882202F3B00/Documents/attachement.png”

When I reading the file from the path, I got the error. 当我从路径中读取文件时，出现错误。 I am using the following code 我正在使用以下代码

  NSBundle *bundle = [NSBundle mainBundle]; 


  NSString *path = [bundle bundlePath];
    NSURL *baseURL = [NSURL fileURLWithPath:path];

    NSString *commentHtml = [NSString stringWithFormat:@"<img src=\"%@\"/>", documentEntity.path];
    NSString *html3 = [NSString stringWithFormat:@"<html><head/><body><div><b>COMMENTS:</b></div>%@</body></html>", commentHtml];
    [self.documentView loadHTMLString:html3 baseURL:baseURL];

Please help me. 请帮我。

If you have saved the Image in Documents Folder, why are you fetching from MainBundle. 如果已将“图像”保存在“文档”文件夹中，为什么要从MainBundle中提取图像。 Fetching Image from the Documents Directory would be : 从文档目录中获取图像将是：

    NSString *aDocumentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
    NSString *aFilePath = [NSString stringWithFormat:@"%@/attachement.png", aDocumentsDirectory];
    UIImage *anImage = [UIImage imageWithContentsOfFile:aFilePath];
