You can contact me, help you debug it,

CodePudding user response:

No instance dispatchSrc

CodePudding user response:

Check the dispatchSrc,
If it is a pointer variable, should according to dispatchSrc - & gt; Use something form,
If it is a object instance, should according to dispatchSrc. Use something form,

And please note that before the incoming function, dispatchSrc parameters should have correct assignment,
