如何使用包含cdata的字符串创建Image（来自包含cdata的xml图像标记的nsstring）

Question

我使用soap方法来使用Web服务，响应在wsdl中，xml图像标记包含cdata，我想知道如何使用这种类型的数据创建uiimage。

NSData* imageData =  [[[[servicesArray objectAtIndex:indexPath.row]valueForKey:@"image"] valueForKey:@"text"]  dataUsingEncoding:NSUTF8StringEncoding];
UIImage* image = [[UIImage alloc] initWithData:imageData];//[UIImage imageWithData:imageData];

但我的结果是零 这是cdata

首先，您必须将CData转换为NSData：

NSData *myData = (__bridge NSData*)my_cfdata;;

然后使用它来获取UIImage： -

UIImage* image = [[UIImage alloc] myData];
