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);
