Create PDF file
Sometimes we need to make the pdf file for saving the image or string (No editable) . for this we need to follow some steps.
1: Collect your all strings data and images and write the function to call.

- (IBAction) createPdf:(id)sender { //Get Document Directory path= NSArray * dirPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //Define path for PDF file NSString * documentPath = [[dirPath objectAtIndex:0] stringByAppendingPathComponent:@"Heading2.PDF"]; UIGraphicsBeginPDFContextToFile(documentPath, CGRectZero, nil); // Mark the beginning of a new page.

UIGraphicsEndPDFContext(); } |
Here first you need to calculate the height and width of string that will take due to that reason I have used UILabel for calculating their width and height and set font after this we plot on pdf file.
Now write their function in same class.

CGContextTranslateCTM(currentContext, 0, frameRect.origin.y*2); CGContextScaleCTM(currentContext, 1.0, -1.0); // Draw the frame. CTFrameDraw(frameRef, currentContext); CGContextScaleCTM(currentContext, 1.0, -1.0); CGContextTranslateCTM(currentContext, 0, (-1)*frameRect.origin.y*2); CFRelease(frameRef); CFRelease(stringRef); CFRelease(framesetter); } +(void)drawImage:(UIImage*)image inRect:(CGRect)rect { [image drawInRect:rect]; } +(void)drawLogo :(CGRect)inRect{ UIImage* logo = [UIImage imageNamed:@"ray-logo.png"]; [self drawImage:logo inRect:inRect]; } |
2: Now you need to access the pdf file and display.

- (IBAction)show:(id)sender { NSError *error; NSString *filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject] stringByAppendingPathComponent:@"Heading1.PDF"]; NSString *str = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error]; NSLog(@"%@", filePath); String filePath1 = filePath; } |
3: after this, we need to open this file using web view.

NSURL *urlen = [NSURL fileURLWithPath:_filepath]; NSURLRequest *urlRequest = [NSURLRequest requestWithURL:urlen]; [_webView loadRequest:urlRequest]; [_webView setScalesPageToFit:YES]; |
