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
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 .
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wno-unused-getter-return-value" // or whatever
-(void)yourMethodHere{
// generate warning
}
#pragma clang diagnostic pop
