iOS 创建PDF
示例
UIGraphicsBeginPDFContextToFile(fileName, CGRectZero, nil);
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, 612, 792), nil);
[self drawText];
UIGraphicsEndPDFContext();fileName是您要在其中添加或附加的文档文件
NSString* temporaryFile = @"firstIOS.PDF";
NSArray *arrayPaths =
NSSearchPathForDirectoriesInDomains(
NSDocumentDirectory,
NSUserDomainMask,
YES);
NSString *path = [arrayPaths objectAtIndex:0];
NSString* fileName = [path stringByAppendingPathComponent:fileName];其中drawText是
(void)drawText
{
NSString* textToDraw = @"Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.";
CFStringRef stringRef = (__bridge CFStringRef)textToDraw;
CFAttributedStringRef currentText = CFAttributedStringCreate(NULL, stringRef, NULL);
CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString(currentText);
CGRect frameRect = CGRectMake(0, 0, 300, 100);
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, 450);
CGContextScaleCTM(currentContext, 2, -2);
CTFrameDraw(frameRef, currentContext);
CFRelease(frameRef);
CFRelease(stringRef);
CFRelease(framesetter);
