Crash when setStrokeColor is null in iOS 7

Hi , there. I use this great open source. thank you.

By the way ,I encountered crash bug recently.

my code THLabel albumButtonLabel = [[THLabel alloc] initWithFrame:CGRectMake(albumButton.frame.origin.x - 10, albumButton.frame.origin.y + albumButton.frame.size.height - 15, 170, 33)]; albumButtonLabel.text = NSLocalizedString(@"START_BUTTON_ALBUM", nil); albumButtonLabel.font = [UIFont fontWithName:@"mikachan_o-PB" size:16]; albumButtonLabel.backgroundColor = [UIColor clearColor]; albumButtonLabel.textColor = [UIColor whiteColor]; albumButtonLabel.shadowBlur = 3.0f; albumButtonLabel.shadowColor = [UIColor grayColor]; albumButtonLabel.shadowOffset = CGSizeMake(2.0f, 2.0f); albumButtonLabel.transform = CGAffineTransformMakeRotation(18.0f \ M_PI/180);

In iOS6 , there is no problem without setting strokeColor , but in iOS7 crashed.

crash at // ------- // Step 4: Draw stroke. // ------- if ([self.text respondsToSelector:@selector(sizeWithAttributes:)]) {//colorがnullの時 NSDictionary attrs = @{NSFontAttributeName: font, NSParagraphStyleAttributeName: paragraphStyle, NSStrokeColorAttributeName: self.color NSStrokeWidthAttributeName: @([self strokeSizeDependentOnStrokePosition] \ [UIScreen mainScreen].scale)};

[self drawTextInRect:textRect withAttributes:attrs];

}

crash log * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[2]'

So , I add following code before "NSDictionary *attrs = @{......" id color = self.strokeColor; if(!color){ color = [NSNull null]; }

My test enviroment [iPhone Retina(4-inch , 64bit) iOS 7.0]. [iPhone Retina(4-inch ) iOS 7.0]. [iPhone4 iOS7.0 GM Seed].

Sorry my poor English. Thank in advance.
