  • 干掉xcode 4.2里的performselector警告

    xcode 4.2非常可恶,原来的代码里有调用performselector:withObject:的地方无一例外获得一个警告: Semantic Issue PerformSelector may cause a leak because its selector is unknown warning倒是不影响程序运行,但是这人要是有点代码小洁癖的话,那日子就没法过了,这warning怎么看都碍眼。所以必须得想办法把它弄没了: #pragma clang diagnostic push #pragma clang diagnostic ignored \”-Warc-performSelector-leaks\” [self performSelector:nextView]; #pragma clang diagnostic pop 世界清静啦
