下面是我的代码崩溃
CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString(currentText);
我正在尝试设置字体,请帮助我谢谢。
+(void)drawText:(NSString*)textToDraw inFrame:(CGRect)frameRect
{
// CFStringRef stringRef = (__bridge CFStringRef)textToDraw;
// Prepare the text using a Core Text Framesetter
NSAttributedString *stringRef=[[[NSAttributedString alloc]initWithString:textToDraw attributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont boldSystemFontOfSize:12.0],(NSString*)kCTFontAttributeName, nil]]autorelease];
CFAttributedStringRef currentText =(__bridge CFAttributedStringRef)stringRef;
CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString(currentText);// at this Line it giving me EXC_BAD_ACCESS
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(currentText);
CFRelease(framesetter);
//CFRelease(stringRef);
