如何在Objective-C中的PDF中添加欧元货币符号

Question

I am making a PDF file in Objective-C and all goes well. But when I add some curreny symbols in the PDF, it shows something totally different.

‚dž2,060,0 instead of €2,060,0

I have uses the following code to draw text in a PDF:

NSString *reducedString = @"€4,854,525";
CGContextShowTextAtPoint (currentContext,xPos, yPos, [textToDraw UTF8String], [reducedString length]);

Anyone knows how to draw the Euro symbol using this same code ? Is there anything I need to change in the text encoding?

[reducedString drawAtPoint:CGPointMake(xPos  ,yPos) withFont:[UIFont systemFontOfSize:15];

Thanks in advance.

尝试使用欧元符号的unicode

Right way to go is needs to use NSNumberFormatter.

NSInteger currency = 4345;
NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init] autorelease];
[numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
NSString *result = [numberFormatter stringFromNumber:[NSNumber numberWithInteger:currency]];

And result will be string with currency sign depending on the locale.

Try this

//for the document Header
NSString *textToDraw = @"Your text";
UIFont *font = [UIFont boldSystemFontOfSize:18.0];
CGSize stringSize = [textToDraw sizeWithFont:font constrainedToSize:CGSizeMake(pageSize.width - 2*kBorderInset, pageSize.height - 2*kBorderInset - 2*kMarginInset) lineBreakMode:UILineBreakModeWordWrap];
//for title
fYheight=fYheight+25;
CGRect renderingRect = CGRectMake(kBorderInset, fYheight, pageSize.width - 2*kBorderInset, stringSize.height);
[textToDraw drawInRect:renderingRect withFont:font lineBreakMode:UILineBreakModeWordWrap alignment:UITextAlignmentCenter];

Add your text to textToDraw string. No need to convert to constant char.
