Populate table in pdf - objective-C - ios

Question

I draw a table view in a pdf like in this tutorial and it works when the table was so big like in tutorial , but i need a little table so i have changed :
int xOrigin = 350;
int yOrigin = 200;
int rowHeight = 10;
int columnWidth = 35;
int numberOfRows = 6;
int numberOfColumns = 3;
[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];
and now the table is empty :( Have anyone any ideea about how can i populate again the table ?

Answer 1

With reference to the example you used in method
+(void)drawTableDataAt:(CGPoint)origin
withRowHeight:(int)rowHeight
andColumnWidth:(int)columnWidth
andRowCount:(int)numberOfRows
andColumnCount:(int)numberOfColumns
padding = 10
change your size to 20

Answer 2

This method is used to show with what data the table is populated
+(void)drawTableDataAt:(CGPoint)origin
withRowHeight:(int)rowHeight
andColumnWidth:(int)columnWidth
andRowCount:(int)numberOfRows
andColumnCount:(int)numberOfColumns
{
int padding = 10;
NSArray* headers = [NSArray arrayWithObjects:#"Quantity", #"Description", #"Unit price", #"Total", nil];
NSArray* invoiceInfo1 = [NSArray arrayWithObjects:#"1", #"Development", #"$1000", #"$1000", nil];
NSArray* invoiceInfo2 = [NSArray arrayWithObjects:#"1", #"Development", #"$1000", #"$1000", nil];
NSArray* invoiceInfo3 = [NSArray arrayWithObjects:#"1", #"Development", #"$1000", #"$1000", nil];
NSArray* invoiceInfo4 = [NSArray arrayWithObjects:#"1", #"Development", #"$1000", #"$1000", nil];
NSArray* allInfo = [NSArray arrayWithObjects:headers, invoiceInfo1, invoiceInfo2, invoiceInfo3, invoiceInfo4, nil];
for(int i = 0; i < [allInfo count]; i++)
{
NSArray* infoToDraw = [allInfo objectAtIndex:i];
for (int j = 0; j < numberOfColumns; j++)
{
int newOriginX = origin.x + (j*columnWidth);
int newOriginY = origin.y + ((i+1)*rowHeight);
CGRect frame = CGRectMake(newOriginX + padding, newOriginY + padding, columnWidth, rowHeight);
[self drawText:[infoToDraw objectAtIndex:j] inFrame:frame];
}
}
}
This below pasted method is used to draw the text within table cells
+(void)drawText:(NSString*)textToDraw inFrame:(CGRect)frameRect
{
CFStringRef stringRef = (__bridge CFStringRef)textToDraw;
// Prepare the text using a Core Text Framesetter
CFAttributedStringRef currentText = CFAttributedStringCreate(NULL, stringRef, NULL);
CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString(currentText);
CGMutablePathRef framePath = CGPathCreateMutable();
CGPathAddRect(framePath, NULL, frameRect);
// Get the frame that will do the rendering.
CFRange currentRange = CFRangeMake(0, 0);
CTFrameRef frameRef = CTFramesetterCreateFrame(framesetter, currentRange, framePath, NULL);
CGPathRelease(framePath);
// Get the graphics context.
CGContextRef currentContext = UIGraphicsGetCurrentContext();
// Put the text matrix into a known state. This ensures
// that no old scaling factors are left in place.
CGContextSetTextMatrix(currentContext, CGAffineTransformIdentity);
// Core Text draws from the bottom-left corner up, so flip
// the current transform prior to drawing.
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);
}
In case you want to set the text inside small cells with small font size
-(void)drawText:(NSString*)textToDraw inFrame:(CGRect)frameRect
{
int length=[textToDraw length];
CFStringRef string = (__bridge CFStringRef) textToDraw;
CFMutableAttributedStringRef currentText = CFAttributedStringCreateMutable(kCFAllocatorDefault, 0);
CFAttributedStringReplaceString (currentText,CFRangeMake(0, 0), string);
CTFontRef font = CTFontCreateWithName((CFStringRef)#"Helvetica", 8.0f, nil);
CFAttributedStringSetAttribute(currentText,CFRangeMake(0, length),kCTFontAttributeName,font);
CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString(currentText);
CGMutablePathRef framePath = CGPathCreateMutable();
CGPathAddRect(framePath, NULL, frameRect);
CFRange currentRange = CFRangeMake(0, 0);
CTFrameRef frameRef = CTFramesetterCreateFrame(framesetter, currentRange, framePath, NULL);
CGPathRelease(framePath);
CGContextRef currentContext = UIGraphicsGetCurrentContext();
CGContextSetTextMatrix(currentContext, CGAffineTransformIdentity);
CGContextTranslateCTM(currentContext, 0, frameRect.origin.y*2);
CGContextScaleCTM(currentContext, 1.0, -1.0);
CTFrameDraw(frameRef, currentContext);
CGContextScaleCTM(currentContext, 1.0, -1.0);
CGContextTranslateCTM(currentContext, 0, (-1)*frameRect.origin.y*2);
CFRelease(frameRef);
CFRelease(framesetter);
}
