Question

In my work, I just want to read a downloaded PDF in iphone device

At first, I tried to use the “bundleRoot” directory, it is work in simulator but not on device. Now, I just test in simulator for Directory of Document or Cache.

How can I get a writable path on the iPhone?

After I read the above topic,

I have tried using Directory of Document or Cache.

Here is my code in finding the writable path

/******************************************************************************/

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *cachePath = [paths objectAtIndex:0];
BOOL isDir = NO;
NSError *error;

if (! [[NSFileManager defaultManager] fileExistsAtPath:cachePath isDirectory:&isDir] && isDir == NO) {
    [[NSFileManager defaultManager] createDirectoryAtPath:cachePath withIntermediateDirectories:NO attributes:nil error:&error];
}


NSString *path_to_file = [cachePath stringByAppendingPathComponent:@"testing6.pdf"];

/******************************************************************************/

I can find the downloaded file and get the size in this directory,but I cannot read the file by using the following code :

            pdf = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL);

    page = CGPDFDocumentGetPage(pdf, 1);
    CGPDFPageRetain(page);

    CGRect pageRect = CGPDFPageGetBoxRect(page, kCGPDFMediaBox);

The return pageRect.size.width is 0

After I print out the download and retrieve file path also are :

/Users/ITDEV/Library/Application Support/iPhone Simulator/4.3.2/Applications/806ED359-70F8-4C07-996F-6AFC959B3FC7/Library/Caches/testing6.pdf

Anyone can help me pls?

If all other answers won’t work then try using NSBundle as below:

NSString *path = [[NSBundle mainBundle] pathForResource:@"myfilename" ofType:@"pdf"];
NSLog("path : %@",path);

Same problem i faced and i found that my plist file was not in Documents directory but instead it shows me path to my app and then it shows MYAppName.app/myPlist.plist file. This means that the app file includes my plist file in its own bundle i.e. MainBundle.
