Question

I am new to iphone development. I am developing an iphone application in which i am downloading files using web service with following code:

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *basePath =  [paths objectAtIndex:0];
NSString *fileLoc = [basePath stringByAppendingString:@"/filename.pdf"];
NSData *fileData = [self decodeBase64WithString:soapResults];
[fileData writeToFile:fileLoc atomically:YES];

And my file is in path : /Users/myusername/Library/Application Support/iPhone Simulator/4.0/Applications/7A627E64-DEAB-40FA-BE04-35ED50580B65/filename.pdf

How can i open this file using uiwebview??? I tried this:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *basePath =  [paths objectAtIndex:0];
NSString *fileLoc = [basePath stringByAppendingString:@"/filename"];
[self loadDocument:fileLoc inView:mywebview];

My loadDocument method is:

-(void)loadDocument:(NSString*)documentName inView:(UIWebView*)webView
{
NSString *path = [[NSBundle mainBundle] pathForResource:documentName ofType:@"pdf"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];  
}

But it showing error… I think location is the problem.. How can i find the path in simulator as well as in orignal device???

Please help me…

pathForResource:ofType: can only be used to load resource files, which are shipped as part of your application bundle. You’re trying to load a downloaded file from your Documents directory. So you should be able to just do

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *basePath =  [paths objectAtIndex:0];
NSString *fileLoc = [basePath stringByAppendingString:@"/filename.pdf"];
NSURL *url = [NSURL fileURLWithPath:fileLoc];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];
