Xcode15适配

一、绘制图片崩溃

在将颜色绘制成图片时，出现了崩溃，原因为传入的size为0。

arduino 复制代码

+ (UIImage *)imageWithColor:(UIColor *)color withSize:(CGSize)size {
    CGRect rect = CGRectMake(0, 0, size.width, size.height);
    UIGraphicsBeginImageContextWithOptions(rect.size, NO, 0);
    [color setFill];
    UIRectFill(rect);   // Fill it with your color
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}

发现UIGraphicsBeginImageContextWithOptions在iOS17被标记为过时。使用新方法修改为：

ini 复制代码

+ (UIImage *)imageWithColor:(UIColor *)color withSize:(CGSize)size {
    UIGraphicsImageRendererFormat *format = [[UIGraphicsImageRendererFormat alloc] init];
    format.opaque = NO;
    format.scale = 0.0;
    UIGraphicsImageRenderer *render = [[UIGraphicsImageRenderer alloc] initWithSize:size format:format];
    UIImage *image = [render imageWithActions:^(UIGraphicsImageRendererContext * _Nonnull rendererContext) {
        CGRect rect = CGRectMake(0, 0, size.width, size.height);
        [color setFill];
        UIRectFill(rect);
    }];
    
    return image;
}

测试一切正常。

二、报错`DT_TOOLCHAIN_DIR`

编译的时候报错DT_TOOLCHAIN_DIR cannot be used to evaluate LIBRARY_SEARCH_PATHS, use TOOLCHAIN_DIR instead,这需要全局（包括第三方库）都要替换哈。

解决方法，直接在Podfile中修改，如下：

lua 复制代码

post_install do |installer|
  flutter_post_install(installer) if defined?(flutter_post_install)

  installer.aggregate_targets.each do |target|
    target.xcconfigs.each do |variant, xcconfig|
      xcconfig_path = target.client_root + target.xcconfig_relative_path(variant)
      IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
    end
  end

  installer.pod_target_subprojects.flat_map { |p| p.targets }.each do |target|

    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
      config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"

      if config.base_configuration_reference.is_a? Xcodeproj::Project::Object::PBXFileReference
        xcconfig_path = config.base_configuration_reference.real_path
        IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
      end
    end
  end
end

修改之前是

ruby 复制代码

post_install do |installer|
  flutter_post_install(installer) if defined?(flutter_post_install)
  
  installer.pod_target_subprojects.flat_map { |p| p.targets }.each do |target|
    target.build_configurations.each do |c|
      c.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
      c.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
    end
  end
end

添加了其中的DT_TOOLCHAIN_DIR相关内容。修改后记得删除Pods文件夹，重新pod install.

三、报错`compact unwind compressed function offset doesn't fit in 24 bits`

编译时出现Assertion failed: (false && "compact unwind compressed function offset doesn't fit in 24 bits"), function operator(), file Layout.cpp, line 5758.的报错。

解决方法：在Other Linker Flags中添加**-ld_classic**.

四、个推崩溃

升级到Xcode15后运行在iOS17系统没有问题，但是在iOS17以下的系统，那么就会崩溃啊。崩溃日志如下

less 复制代码

此现象必现，所以可以判断一定个推的问题了，直接联系了个推官方，10分钟后得到答复，是最低支持版本的问题。

解决方法：

五。Done

编译成功，运行成功，使用Xcode15提交App Store，审核成功。
