pdf show in simulator but not in iPhone - iphone

Question

I am struggling with the problem from last few hour. I make a pdf programmatically and save it on ~/library/Application Support/iPhone Simulator/... and the programs work fine for me in simulator. I can save and retrieve the pdf in webView.
But when I test my App in iPhone4 device I not see the pdf file when I retrieve. I am new so I don't know check manually that pdf created in device or not.
Please provide me help.
thanks
I save the pdf from this code :
- (void)generatePdfButtonPressed{
pageSize = CGSizeMake(612, 792);
NSString *fileName = #"Demo.pdf";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];
[self generatePdfWithFilePath:pdfFileName];
}
- (void) generatePdfWithFilePath: (NSString *)thefilePath
{
UIGraphicsBeginPDFContextToFile(thefilePath, CGRectZero, nil);
NSInteger currentPage = 0;
BOOL done = NO;
do
{
// Mark the beginning of a new page.
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, pageSize.width, pageSize.height), nil);
// Draw a page number at the bottom of each page.
currentPage++;
//[self drawPageNumber:currentPage];
//Draw a border for each page.
// [self drawBorder];
//Draw text fo our header.
[self drawHeader];
//Draw a line below the header.
[self drawLine];
//Draw personel details
[self drawPersonelDetail];
//Draw Education
[self drawEducation];
//Draw work Experiences
[self drawWorkExperiences];
//Draw work Activities
[self drawActivities];
//Draw Skills
[self drawSkils];
//Draw some text for the page.
// [self drawText];
yCord=550;
// [self drawText];
//Draw an image
// [self drawImage];
done = YES;
}
while (!done);
// Close the PDF context and write the contents out.
UIGraphicsEndPDFContext();
}

After a long struggling I find the solution of my own question : I provide solution below may be it help any other.
- (void)generatePdfButtonPressed{
pageSize = CGSizeMake(612, 792);
NSString *fileName = #"Demo.pdf";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];
[self generatePdfWithFilePath:pdfFileName];
}
- (void) generatePdfWithFilePath: (NSString *)thefilePath
{
UIGraphicsBeginPDFContextToFile(thefilePath, CGRectZero, nil);
NSInteger currentPage = 0;
BOOL done = NO;
do
{
// Mark the beginning of a new page.
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, pageSize.width, pageSize.height), nil);
// Draw a page number at the bottom of each page.
currentPage++;
[self drawPageNumber:currentPage];
//Draw a border for each page.
[self drawBorder];
//Draw text our header.
[self drawHeader];
//Draw a line below the header.
[self drawLine];
//Draw personel details
[self drawPersonelDetail];
//Draw Education
[self drawEducation];
//Draw an image
[self drawImage];
done = YES;
}
while (!done);
// Close the PDF context and write the contents out.
UIGraphicsEndPDFContext();
}
And for Display the pdf file the method is :
- (void)showPdfClicked
{
pdf1View.scalesPageToFit = YES;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSLog(#"%#",documentsDirectory);
NSString *path1 =[documentsDirectory stringByAppendingPathComponent:#"Demo.pdf"];
NSLog(#"Retruve Save path is %#: ",path1);
// NSString *path1 = [[NSBundle mainBundle] pathForResource:#"pdf1" ofType:#"pdf"];
NSURL *targetURL1 = [NSURL fileURLWithPath:path1];
NSURLRequest *request1 = [NSURLRequest requestWithURL:targetURL1];
[pdf1View loadRequest:request1];
}

Answer 2

I've run into this problem before. My guess is it's a memory issue--how large is the PDF file you're trying to load? UIWebView seems to have have some issues buffering (if it does this at all) large files for display.

I successfully send my created pdf by email through this code. May Be this helps you(dottorfeelgood).
-(IBAction)emailButtonClicked
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:#"Subject"];
NSString *fileName = #"Demo.pdf";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];
NSMutableData *pdfData = [NSMutableData data];
pdfData = [NSData dataWithContentsOfFile:pdfFileName];
CGRect bounds=CGRectMake(0, 0, 612, 792);
[picker addAttachmentData:pdfData mimeType:#"application/pdf" fileName:#"SomeFile.pdf"];
// Fill out the email body text
NSString *emailBody = #"Image is attached";
[picker setMessageBody:emailBody isHTML:NO];
[self presentModalViewController:picker animated:YES];
//[picker release];
}
Happy Coding!!!
