推荐答案

嗨..让你的网址/地址是 http://www.example.com/ ，而文件名是 link.txt 。当您的应用程序加载时，您可以更改任何字符串中的文件名，然后附加字符串..然后将网址加载到您的网页视图。



Code Bellow，

Hi .. Let your url / address is http://www.example.com/ , and ur file name is link.txt. when ur application load u can change the file name in any string then append the string .. then load the url to ur web view.

Code Bellow,

NSString *fileName = @"demo.txt";
NSString *address = @"https://www.example.com/";
address = [address stringByAppendingString:fileName];
NSLog(@"%@",address); // check ur url link in the debug terminal, it should be like .
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
[self.webView loadRequest:request];

地址应该是这样的： - http://www.example.com/link.txt [ ]



好​​的，

然后如果你想下载按钮上的文件单击执行此操作，下载并将文件下载到您的设备

在按钮操作上写下此方法，

address should be like :- http://www.example.com/link.txt[]

Okay ,
then if u want to download the file on button click do this, download and the file to ur device
write this method on button action,

NSData *urlData = [NSData dataWithContentsOfURL:url];
NSString  *filePath;
NSArray  *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString  *documentsDirectory = [paths objectAtIndex:0];
filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"filename.txt"];
NSLog(@"%@",filePath);
[urlData writeToFile:filePath atomically:YES];

如果你想让你的网页浏览自动执行此操作，只需在加载网页视图和上述方法后稍加延迟。

If u want you web view to do this automatically, just give some delay after web view loaded and the above method.
