ios将网页保存为pdf [英] ios save web page as pdf

问题描述

有人能指出我将网页另存为pdf的正确方向吗？我已经有一个iOS pdf阅读器库，但我需要以某种方式实现一个功能，以保存用户正在查看的任何网页为pdf。我假设我必须使用应用内浏览器。有什么想法？

Can someone point me in the right direction for saving a webpage as a pdf? I already have a library for an iOS pdf reader, but I need to somehow implement a feature for saving whatever webpage the user is viewing as pdf. I am assuming I would have to use an in-app browser. Any thoughts?

推荐答案

这不是我做过的事情，但似乎你不是第一个想要做某事的人喜欢这个。

This is not something that I have done, but it seems you are not the first to want to do something like this.

此链接的最后一篇文章提供了将UIWebView保存为图像的代码，您应该能够将该图像转换为PDF。我没有把它归功于代码，因为我没有写它，只是连接你两个：）

The last post in this link provides code to save a UIWebView as an image, and you should be able to convert that image into a PDF. I don't take credit for the code as I did not write it, just connecting you two :)

这是简单的代码：

CGSize sixzevid=CGSizeMake(1024,1100);
UIGraphicsBeginImageContext(sixzevid);
[webview.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

NSData *imageData = UIImagePNGRepresentation(viewImage);

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *pathFloder = [[NSString alloc] initWithString:[NSString stringWithFormat:@"%@",@"new.png"]];
NSString *defaultDBPath = [documentsDirectory stringByAppendingPathComponent:pathFloder];


[imageData writeToFile:defaultDBPath atomically:YES];

很有可能你必须调整这个但是，希望这可以帮助你向右移动方向。

Chances are pretty good that you will have to tweak this but, hopefully this helps you move in the right direction.
