// Only override drawRect: if you perform custom drawing.

// An empty implementation adversely affects performance during animation.

- (void)drawRect:(CGRect)rect

{

// Drawing code

UIBezierPath *roundedRect = [UIBezierPath bezierPathWithRoundedRect:self.bounds cornerRadius:[self cornerRadius]];

[roundedRect addClip];

[[UIColor whiteColor] setFill];

UIRectFill(self.bounds);

[[UIColor blackColor] setStroke];

[roundedRect stroke];

if(self.faceUP){

UIImage *faceImage = [UIImage imageNamed:[NSString stringWithFormat:@"%@%@", [self rankAsString], self.suit]];

if (faceImage) {

CGRect imageRect = CGRectInset(self.bounds,

self.bounds.size.width * (1.0-self.faceCardScaleFactor),

self.bounds.size.height * (1.0-self.faceCardScaleFactor));

[faceImage drawInRect:imageRect];

} else {

[self drawPips];

}

[self drawCorners];

}else{

[[UIImage imageNamed:@"cardback"] drawInRect:self.bounds];

}

NSLog(@"drawRect");

}

这里设置了倒角，阴影，颜色，还有图片

- (void)pushContextAndRotateUpsideDown

{

CGContextRef context = UIGraphicsGetCurrentContext();

CGContextSaveGState(context);

CGContextTranslateCTM(context, self.bounds.size.width, self.bounds.size.height);

CGContextRotateCTM(context, M_PI);

}

- (void)popContext

{

CGContextRestoreGState(UIGraphicsGetCurrentContext());

}

#pragma mark - Corners

- (void)drawCorners

{

NSMutableParagraphStyle *paragraphyStyle = [[NSMutableParagraphStyle alloc] init];

paragraphyStyle.alignment = NSTextAlignmentCenter;

UIFont *cornerFont = [UIFont preferredFontForTextStyle:UIFontTextStyleBody];

cornerFont = [cornerFont fontWithSize:cornerFont.pointSize * [self cornerScaleFactor]];

NSAttributedString *cornerText = [[NSAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@\n%@", [self rankAsString], self.suit] attributes:@{ NSFontAttributeName : cornerFont, NSParagraphStyleAttributeName : paragraphyStyle}];

CGRect textBounds;

textBounds.origin = CGPointMake([self cornerOffset], [self cornerOffset]);

textBounds.size = [cornerText size];

[cornerText drawInRect:textBounds];

[self pushContextAndRotateUpsideDown];

[cornerText drawInRect:textBounds];

[self popContext];

}

这里设置了角落上的suit和rank
