YYText是我们iOS开发中常用的一个开源第三方组件,原作者已停止维护,在最新的iOS17上会触发断言崩溃:
UIGraphicsBeginImageContext() failed to allocate CGBitampContext: size={382, 0}, scale=3.000000, bitmapInfo=0x2002. Use UIGraphicsImageRenderer to avoid this assert.
原因是UIGraphicsBeginImageContext在iOS 17上已经deprecated了,如果项目中暂时无法移除YYText,可以尝试使用下面的方法进行修复
1、移出YYText在cocopads中的引用:
# pod "YYText"
2、手动导入YYText
3、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);
再重新运行项目即可。
