YYText iOS17 崩溃处理

YYText 在iOS17的系统上运行可能会崩溃，
经查询发现api弃用 UIGraphicsBeginImageContext （deprecated）

处理方案： YYTextAsyncLayer.m 更新
原文件

UIGraphicsBeginImageContextWithOptions(self.bounds.size, self.opaque, self.contentsScale);
CGContextRef context = UIGraphicsGetCurrentContext();
if (self.opaque) {
CGSize size = self.bounds.size;
size.width *= self.contentsScale;
size.height *= self.contentsScale;
CGContextSaveGState(context); {
if (!self.backgroundColor || CGColorGetAlpha(self.backgroundColor) < 1) {
CGContextSetFillColorWithColor(context, [UIColor whiteColor].CGColor);
CGContextAddRect(context, CGRectMake(0, 0, size.width, size.height));
CGContextFillPath(context);
}
if (self.backgroundColor) {
CGContextSetFillColorWithColor(context, self.backgroundColor);
CGContextAddRect(context, CGRectMake(0, 0, size.width, size.height));
CGContextFillPath(context);
}
} CGContextRestoreGState(context);
}
task.display(context, self.bounds.size, ^{return NO;});
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
self.contents = (__bridge id)(image.CGImage);

更新后

  UIGraphicsImageRendererFormat *format = [[UIGraphicsImageRendererFormat alloc] init];
        format.opaque = self.opaque;
        format.scale = self.contentsScale;

        UIGraphicsImageRenderer *renderer = [[UIGraphicsImageRenderer alloc] initWithSize:self.bounds.size format:format];
        UIImage *image = [renderer imageWithActions:^(UIGraphicsImageRendererContext * _Nonnull rendererContext) {
            CGContextRef context = rendererContext.CGContext;
            if (self.opaque) {
                CGSize size = self.bounds.size;
                size.width *= self.contentsScale;
                size.height *= self.contentsScale;
                CGContextSaveGState(context); {
                    if (!self.backgroundColor || CGColorGetAlpha(self.backgroundColor) < 1) {
                        CGContextSetFillColorWithColor(context, [UIColor whiteColor].CGColor);
                        CGContextAddRect(context, CGRectMake(0, 0, size.width, size.height));
                        CGContextFillPath(context);
                    }
                    if (self.backgroundColor) {
                        CGContextSetFillColorWithColor(context, self.backgroundColor);
                        CGContextAddRect(context, CGRectMake(0, 0, size.width, size.height));
                        CGContextFillPath(context);
                    }
                } CGContextRestoreGState(context);
            }
            task.display(context, self.bounds.size, ^{return NO;});
        }];

        self.contents = (__bridge id)(image.CGImage);
