本人是开发iPhone应用的,现在用户给了一些UITextView,我需要把它转换成PDF文件然后存储在本地,不知道怎么做?谢谢大家的帮忙。
用UIKit可以把UITextView转为PDF文件的
具体的用法你可以去网上搜一下,也可以看看这个说明链接
试试代码:
- (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 some text for the page.
[self drawText];
//Draw an image
[self drawImage];
done = YES;
}
while (!done);
// Close the PDF context and write the contents out.
UIGraphicsEndPDFContext();
}
- (void) drawText
{
CGContextRef currentContext = UIGraphicsGetCurrentContext();
CGContextSetRGBFillColor(currentContext, 0.0, 0.0, 0.0, 1.0);
NSString *textToDraw = yourtextview.text // use your textfield or textview here
UIFont *font = [UIFont systemFontOfSize:14.0];
CGSize stringSize = [textToDraw sizeWithFont:font
constrainedToSize:CGSizeMake(pageSize.width - 2*kBorderInset- 2*kMarginInset, pageSize.height - 2*kBorderInset - 2*kMarginInset)
lineBreakMode:UILineBreakModeWordWrap];
CGRect renderingRect = CGRectMake(kBorderInset + kMarginInset, kBorderInset + kMarginInset + 50.0, pageSize.width - 2*kBorderInset - 2*kMarginInset, stringSize.height);
[textToDraw drawInRect:renderingRect
withFont:font
lineBreakMode:UILineBreakModeWordWrap
alignment:UITextAlignmentLeft];
}
