在iOS17上，YYText会报以下错误：

UIGraphicsBeginImageContext() failed to allocate CGBitampContext: size={0, 0}, scale=3.000000, bitmapInfo=0x2002. Use UIGraphicsImageRenderer to avoid this assert.

解决方法如下：
在YYTextAsyncLayer.m文件中，_displayAsync:(BOOL)async 方法中。
原代码：

	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);

修复后的代码：

 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);
