   \# 处理 M1 芯片上不支持 模拟器 运行问题：不仅仅编译活跃的架构，反之就是 i386、x86_64、arm64 等架构都编译。

   config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'

   config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = "arm64"

iOS 18适配问题记录(Xcode16正式版)

问题1：ADClient编译报错问题

报错信息

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_ADClient", referenced from:
       in ViewController.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

相关代码（demo）

原因

苹果对AdClicent API加了一个标识
ADCLIENT_DEPRECATED_IOS_90_145_OBSOLETED_180
表示：iOS7.1-iOS14.5可用，iOS18彻底废弃，会在iOS18系统上编译失败。

解决办法

使用AdService库的AAAttribution替代，注意iOS14.3才可以使用。

            ...
        }

问题2：Xcode16（正式版）运行时，YYCache导致crash

报错信息

在 iOS18 中，需要提前对 sqlite3_stmt 执行 sqlite3_finalize。

libc++abi: terminating due to uncaught exception of type NSException

原因

iOS 18 对 UIView的maskView 增加了断言，导致如果业务代码里有同名属性可能导致触发该断言。

经测试发现：
1.自定义UIView子视图，存在同名属性maskView，会崩溃
2.自定义cell，添加到cell视图上会崩溃，添加到contentView上，则不会崩溃
3.控制器里的maskView视图属性，添加到控制器view，不会崩溃

解决办法

修改自定义视图，将自定义子组件名为maskView的视图进行重命名。
