前言
有些时候Xcode的警告过多，或者有些警告是多余的，可以使用#pragma clang diagnostic语法去除。
语法
- 适用整个.m文件
#pragma GCC diagnostic ignored "-W+相关命令"
@implementation BDActionSheetInvite
- 适用指定代码
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-W+相关命令"
[weakSelf performSelector:NSSelectorFromString(selectorStr)];
#pragma GCC diagnostic pop
GCC可以替换为clang
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-W+相关命令"
[weakSelf performSelector:NSSelectorFromString(selectorStr)];
#pragma clang diagnostic pop
几个常用的命令
#pragma clang diagnostic ignored "-Warc-performSelector-leaks"
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
#pragma clang diagnostic ignored "UnavailableInDeploymentTarget"
#pragma clang diagnostic ignored "-Wunused-variable"
#pragma clang diagnostic ignored "UnresolvedMessage"
#pragma clang diagnostic ignored "-Wincompatible-pointer-types"
#pragma clang diagnostic ignored "-Warc-retain-cycles"
