如何禁用Xcode编译器警告“属性访问结果未使用-吸气剂不应用于副作用”

Question

我想知道如何禁用标题为：属性访问结果未使用的Xcode编译器警告-不应将吸气剂用于副作用

Answer 1

The best approach would probably be to cast to void , or assign to an unused variable ( T unused_var = property_access; ), and add a comment to the line stating why the return value is being discarded. However...

Find the project setting for compiler flags and add:

-Wno-unused-getter-return-value

This comes from Clang Options to Control Error and Warning Messages and Diagnostics Flags in Clang .

Answer 2

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wno-unused-getter-return-value" // or whatever

-(void)yourMethodHere{
// generate warning
}

#pragma clang diagnostic pop
