I am trying to create a multipage PDF. I have followed this tutorial.
This is working with a XIB file for static text and then adds a table from code. But the problem I'm having ATM is that when the table is bigger then one page. When the table has more then 9 rows. It should continue on the next page.
This is what I'm doing in code.
+(void)drawPDF:(NSString*)fileName
{
NSMutableDictionary *mutDictValues = [[[NSUserDefaults standardUserDefaults] objectForKey:#"dicValues"] mutableCopy];
NSMutableArray *arrSelectedCities = [[mutDictValues objectForKey:#"cities"]mutableCopy ];
if(arrSelectedCities.count <= 8){
// If there are only 8 rows --> we can fit everyting on one page !
// Create the PDF context using the default page size of 612 x 792.
UIGraphicsBeginPDFContextToFile(fileName, CGRectZero, nil);
// Mark the beginning of a new page.
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, 612, 792), nil);
[self drawLabels];
[self drawLogo];
int xOrigin = 50;
int yOrigin = 350;
int rowHeight = 50;
int columnWidth = 240;
int numberOfRows = 9;
int numberOfColumns = 2;
[self drawTableAt:CGPointMake(xOrigin, yOrigin) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows andColumnCount:numberOfColumns];
[self drawTableDataAt:CGPointMake(xOrigin, yOrigin) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows andColumnCount:numberOfColumns withArray:arrSelectedCities];
// Close the PDF context and write the contents out.
UIGraphicsEndPDFContext();
}else{
// When we have more then 8 rows we should have 2 pages.
NSLog(#"Create 2 pages");
// Create the PDF context using the default page size of 612 x 792.
UIGraphicsBeginPDFContextToFile(fileName, CGRectZero, nil);
// Mark the beginning of a new page.
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, 612, 792), nil);
[self drawLabels];
[self drawLogo];
int xOrigin = 50;
int yOrigin = 350;
int rowHeight = 50;
int columnWidth = 240;
int numberOfRows = 9;
int numberOfColumns = 2;
[self drawTableAt:CGPointMake(xOrigin, yOrigin) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows andColumnCount:numberOfColumns];
[self drawTableDataAt:CGPointMake(xOrigin, yOrigin) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows andColumnCount:numberOfColumns withArray:arrSelectedCities];
// Create the PDF context using the default page size of 612 x 792.
UIGraphicsBeginPDFContextToFile(fileName, CGRectZero, nil);
// Mark the beginning of a new page.
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, 612, 792), nil);
int xOrigin2 = 50;
int yOrigin2 = 60;
int numberOfRows2 = ((arrSelectedCities.count+1)-9);
[self drawTableAt:CGPointMake(xOrigin2, yOrigin2) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows2 andColumnCount:numberOfColumns];
[self drawTableDataAt:CGPointMake(xOrigin2, yOrigin2) withRowHeight:rowHeight andColumnWidth:columnWidth andRowCount:numberOfRows2 andColumnCount:numberOfColumns withArray:arrSelectedCities];
}
// Close the PDF context and write the contents out.
UIGraphicsEndPDFContext();
}
Let me explain what I'm doing here. I have an array that should fill up my tableview. If the array is bigger then 8 then I should use 2 pages. Else everything works with one page.
What this does is, it's creating only the second page....
Can anybody help me?
You should not call UIGraphicsBeginPDFContextToFile() again when creating the second page,
only UIGraphicsBeginPDFPageWithInfo():
UIGraphicsBeginPDFContextToFile(...);
UIGraphicsBeginPDFPageWithInfo(...); // start first page
// ...
UIGraphicsBeginPDFPageWithInfo(...); // start second page
// ...
UIGraphicsEndPDFContext();

You don't need to create context for second page (UIGraphicsBeginPDFContextToFile(fileName, CGRectZero, nil)), you have to only create this page.
You should also remember about closing opened page using CGPDFContextEndPage().

I have 3 images. I load one by one to camera overlay image. Then i need to take snapshot. But when i click button it take snapshot of particular image. When i put imageName.png in captureStillImageWithOverlay it take snapshot of that image only, it won't taking other images when present in overlay
Button click code:
- (void)ButtonPressed {
[[self captureManager] captureStillImageWithOverlay:[UIImage imageNamed:#"img2.png"]];
}
Load images:
-(void)loadNextPage:(int)index
{
int countFlag=0;
for(int i=index*4;i<(index+1)*4;i++)
{
UIButton *imageView=[[UIButton alloc]initWithFrame:CGRectMake((320*index)+countFlag*80+ 2, 5, 75, 75)];
imageView.tag=i+1;
[imageView addTarget:self action:#selector(imageViewClicked:) forControlEvents:UIControlEventTouchUpInside];
[imageView.layer setBorderColor:[UIColor lightGrayColor].CGColor];
[imageView.layer setBorderWidth:1.0f];
switch ((i+1)%5) {
case 0:
[imageView setImage:[UIImage imageNamed:#"img1.png"] forState:UIControlStateNormal];
break;
case 1:
[imageView setImage:[UIImage imageNamed:#"img2.png"] forState:UIControlStateNormal];
break;
case 2:
[imageView setImage:[UIImage imageNamed:#"img3.png"] forState:UIControlStateNormal];
break;
}
[myScrollView addSubview:imageView];
[imageView release];
countFlag++;
}
}
Capture overlay image:
- (void)captureStillImageWithOverlay:(UIImage*)overlay
{
AVCaptureConnection *videoConnection = nil;
for (AVCaptureConnection *connection in [[self stillImageOutput] connections]) {
for (AVCaptureInputPort *port in [connection inputPorts]) {
if ([[port mediaType] isEqual:AVMediaTypeVideo]) {
videoConnection = connection;
break;
}
}
if (videoConnection) {
break;
}
}

[[self stillImageOutput] captureStillImageAsynchronouslyFromConnection:videoConnection
completionHandler:^(CMSampleBufferRef imageSampleBuffer, NSError *error) {
CFDictionaryRef exifAttachments = CMGetAttachment(imageSampleBuffer, kCGImagePropertyExifDictionary, NULL);
if (exifAttachments) {
NSLog(#"attachements: %#", exifAttachments);
} else {
NSLog(#"no attachments");
}
NSData *imageData = [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageSampleBuffer];
UIImage *image = [[UIImage alloc] initWithData:imageData];
CGSize imageSize = [image size];
CGSize overlaySize = [overlay size];
UIGraphicsBeginImageContext(imageSize);
[image drawInRect:CGRectMake(0, 0, imageSize.width, imageSize.height)];
CGFloat xScaleFactor = imageSize.width / 320;
CGFloat yScaleFactor = imageSize.height / 480;
[overlay drawInRect:CGRectMake(30 * xScaleFactor, 100 * yScaleFactor, overlaySize.width * xScaleFactor, overlaySize.height * yScaleFactor)]; // rect used in AROverlayViewController was (30,100,260,200)
UIImage *combinedImage = UIGraphicsGetImageFromCurrentImageContext();
[self setStillImage:combinedImage];
UIGraphicsEndImageContext();
[image release];
[[NSNotificationCenter defaultCenter] postNotificationName:kImageCapturedSuccessfully object:nil];
}];
}
I take the reference from this url [http://www.musicalgeometry.com/?p=1681]
An overlay is just for presentation in the camera picker.
You also need to combine these images in your final UIImage (JPEG or TIFF or whatever) you save to disk.
Other people have had (and have solved) this same problem as you.
EDIT, here is some code that may help you out:
- (void)captureStillImageWithOverlay:(NSArray *) arrayOfImageFiles
{
AVCaptureConnection *videoConnection = nil;
for (AVCaptureConnection *connection in [[self stillImageOutput] connections]) {
for (AVCaptureInputPort *port in [connection inputPorts]) {

videoConnection = connection;
break;
}
}
if (videoConnection) {
break;
}

if (exifAttachments) {
NSLog(#"attachements: %#", exifAttachments);
} else {
NSLog(#"no attachments");
}
NSData *imageData = [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageSampleBuffer];
UIImage *image = [[UIImage alloc] initWithData:imageData];
CGSize imageSize = [image size];
UIGraphicsBeginImageContext(imageSize);
[image drawInRect:CGRectMake(0, 0, imageSize.width, imageSize.height)];
CGFloat xScaleFactor = imageSize.width / 320;
CGFloat yScaleFactor = imageSize.height / 480;
for(NSString * imageFileName in arrayOfImageFiles)
{
// images named #"img1" or #"img1.png" should work
UIImage * overlay = [UIImage imageNamed: imageFileName];
if(overlay)
{
CGSize overlaySize = [overlay size];
[overlay drawInRect:CGRectMake(30 * xScaleFactor, 100 * yScaleFactor, overlaySize.width * xScaleFactor, overlaySize.height * yScaleFactor)]; // rect used in AROverlayViewController was (30,100,260,200)
} else {
NSLog( #"could not find an image named %#", imageFileName);
}
}

I need to take overlay image without setting drawInRect. When i set drawInRect it gives output of setting size. I need to take picture with new size without using following code.

} else {
NSLog(#"no attachments");
}
NSData *imageData = [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageSampleBuffer];
UIImage *image = [[UIImage alloc] initWithData:imageData];
CGSize imageSize = [image size];
CGSize overlaySize = [overlay size];
UIGraphicsBeginImageContext(imageSize);
[image drawInRect:CGRectMake(0, 0, imageSize.width, imageSize.height)];
CGFloat xScaleFactor = imageSize.width / 320;
CGFloat yScaleFactor = imageSize.height / 480;
[overlay drawInRect:CGRectMake(30 * xScaleFactor, 100 * yScaleFactor, overlaySize.width * xScaleFactor, overlaySize.height * yScaleFactor)]; // rect used in AROverlayViewController was (30,100,260,200)
// [overlay drawInRect:CGRectMake(30 * xScaleFactor, 100 * yScaleFactor, overlaySize.width * xScaleFactor, overlaySize.width* yScaleFactor)];
UIImage *combinedImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
// NSData * data = UIImagePNGRepresentation(image);

Try this code :
UIGraphicsBeginImageContext(self.view.bounds.size);
// retrieve the current graphics context
CGContextRef context = UIGraphicsGetCurrentContext();
// render view into context
[self.view.layer renderInContext:context];
// create image from context

Currently I am working on a Paint Application for iPhones and iPads. I want to print the current screen display (Drawing) of the screen. Can any body help me in these case ?
Here is the code i have used so far ,
-(void)printImage {
NSString *path = [[NSBundle mainBundle] pathForResource:#"micky" ofType:#"png"];
NSData *dataFromPath = [NSData dataWithContentsOfFile:path];
UIPrintInteractionController *pCon = [UIPrintInteractionController sharedPrintController];
if(pCon && [UIPrintInteractionController canPrintData:dataFromPath]) {
pCon.delegate = self;
UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputGeneral;
printInfo.jobName = [path lastPathComponent];
printInfo.duplex = UIPrintInfoDuplexLongEdge;
pCon.printInfo = printInfo;
pCon.showsPageRange = YES;
pCon.printingItem = dataFromPath;
void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) = ^(UIPrintInteractionController *printController, BOOL completed, NSError *error) {
if (!completed && error) {
NSLog(#"Unsuccessfull %# error%u", error.domain, error.code);
}
};
[pCon presentAnimated:YES completionHandler:completionHandler];
}
}
Again , all what i want to know is i should be able to print the Current Window(Drawing, Screen) instead of the Image Micky.png (as in the code)
This code takes a screenshot of the current view and outputs an UIImage of it:
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, YES, 0);
CGContextRef context = UIGraphicsGetCurrentContext();
[self.view.layer renderInContext:context];
UIImage *imageFromCurrentView = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
