我想旋转一个CGPath,我使用以下代码:
CGAffineTransform transform = CGAffineTransformMakeRotation(angleInRadians);
CGPathRef rotatedPath = CGPathCreateCopyByTransformingPath(myPath, &transform);
这段代码工作正常,但它改变了路径的位置!我希望路径保持与旋转前相同的位置.
我正在尝试将iAds集成到Admob中介SDK中,我iAdListAdapter从Mediation网站下载链接并将其添加到我的xcode项目中,但是现在当我尝试编译项目时,它给出了以下错误:
Undefined symbols for architecture i386:
"_ADBannerContentSizeIdentifierLandscape", referenced from:
-[GADMAdapterIAd getBannerWithSize:] in libAdapterIAd.a(GADMAdapterIAd.o)

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
请指导我做错了什么或者将iAds添加到Mediation SDk的正确方法:我使用XCode 4.6和min sdk 5.0
任何帮助真的很感激!
