macos - 更新OS X到El Capitan和Core Plot崩溃:(

Question

我的操作系统更新为10.11
试图运行我的在优胜美地上运行良好的项目
但是核心情节有些奇怪
这是崩溃日志，有什么想法吗？

从git hub下载了核心图的新副本
编译为框架和相同的故事:-(

好吧，所以我修改了源代码
如果有人会有同样的问题，这是我的(不是很好的解决方案

在名为CPTTextLayer.m的文件中

-(void)renderAsVectorInContext:(CGContextRef)context
{
    if ( self.hidden ) {
        return;
    }


    //////////////////////////////////////////////////
    //Added by me to avoid crash when self.text
    // or self.attributedText is nil
    //////////////////////////////////////////////////
    if (!self.text || !self.attributedText)
    {
        return;
    }
    ///////////////////////////////////////////////////
    NSString *myText = self.text;
    if ( myText.length > 0 ) {
        [super renderAsVectorInContext:context];

#if TARGET_IPHONE_SIMULATOR || TARGET_OS_IPHONE
        CGContextSaveGState(context);
        CGContextTranslateCTM(context, CPTFloat(0.0), self.bounds.size.height);
        CGContextScaleCTM( context, CPTFloat(1.0), CPTFloat(-1.0) );
#endif

        CGRect newBounds = CGRectInset(self.bounds, kCPTTextLayerMarginWidth, kCPTTextLayerMarginWidth);
        newBounds.origin.x += self.paddingLeft;
#if TARGET_IPHONE_SIMULATOR || TARGET_OS_IPHONE
        newBounds.origin.y += self.paddingTop;
#else
        newBounds.origin.y += self.paddingBottom;
#endif
        newBounds.size.width  -= self.paddingLeft + self.paddingRight;
        newBounds.size.height -= self.paddingTop + self.paddingBottom;



        NSAttributedString *styledText = self.attributedText;




        if ( (styledText.length > 0) && [styledText respondsToSelector:@selector(drawInRect:)] ) {
            [styledText drawInRect:newBounds
                         inContext:context];
        }
        else {
            [myText drawInRect:newBounds
                 withTextStyle:self.textStyle
                     inContext:context];
        }

    #if TARGET_IPHONE_SIMULATOR || TARGET_OS_IPHONE
        CGContextRestoreGState(context);
    #endif
    }
}
