iOS 17.0 YYText 崩溃处理

本文主要是介绍iOS 17.0 YYText 崩溃处理，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

YYText，发现在iOS 17上运行会崩溃，触发了系统的断言：
UIGraphicsBeginImageContext() failed to allocate CGBitampContext: size={382, 0}, scale=3.000000, bitmapInfo=0x2002. Use UIGraphicsImageRenderer to avoid this assert.

查了下 api，发现UIGraphicsBeginImageContext在iOS 17上已经deprecated了。

处理办法：YYTextAsyncLayer.m

将

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);

替换为：

  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);
