Crashes the app, as IOS has deprecated UIGraphicsBeginImageContextWithOptions from IOS 17.

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-native-fast-image@8.6.3 for the project I'm working on.

Getting crash on iOS 17 as UIGraphicsBeginImageContextWithOptions. It crashes the app, as IOS has deprecated UIGraphicsBeginImageContextWithOptions from IOS 17.

Here is the diff that solved my problem:

Had the same issue, your solution solved it for us. Thank you!

@dprajapati1179 I really appreciate sharing your solution, can you please open a PR with this Fix??

[mzbyszynski]

FYI Pr is #1012

Note that the change in pr #1007 is also very similar and should fix this isssue.

Do you have repro steps for this @dprajapati1179 ?

I'm running 8.6.3 and my app seems fine on iOS 17 & 17.1 based on the limited testing i've done.

Thanks for this solution but i found that tintColor prop does not work in this solution hence providing an alternative for the same:

• (UIImage)makeImage:(UIImage )image withTint:(UIColor )color { UIImage newImage = [image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate]; UIGraphicsImageRendererFormat format = [UIGraphicsImageRendererFormat defaultFormat]; UIGraphicsImageRenderer renderer = [[UIGraphicsImageRenderer alloc] initWithSize:image.size format:format];

  UIImage resultImage = [renderer imageWithActions:^(UIGraphicsImageRendererContext _Nonnull rendererContext) { CGRect rect = CGRectMake(0, 0, image.size.width, image.size.height); [newImage drawInRect:rect]; CGContextRef context = rendererContext.CGContext; CGContextSetBlendMode(context, kCGBlendModeSourceAtop); [color setFill]; CGContextFillRect(context, rect); }];

  return resultImage; }

After implementing this patch there is a new error, "nan" in size rather then "0":

UIGraphicsBeginImageContext() failed to allocate CGBitampContext: size={nan, nan}, scale=1.000000, bitmapInfo=0x2002. Use UIGraphicsImageRenderer

any ideas what can cause that?
