舊案一直出現 Error: objc_msgSend Calls Too many arguments to function call, expected 0, have 4

 一個很舊的案子去年改過最近重啟加新需求，去年沒事今年卻出現"Too many arguments to function call, expected 0, have 4"的Error，看了看是objc_msgSend這個造成，但看define: "objc_msgSend(id _Nullable self, SEL _Nonnull op, ...)"也看不出來有4個，3個應該也行吧，Google了下Too many arguments to function call, expected 0, have 3中提到https://github.com/th-in-gs/THObserversAndBinders/blob/master/THObserversAndBinders/THObserver.m，根本跟有幾個參數無關，第一個先將"Apple Clang-Preprocessing"中的"Enable Strict Checking of objc_msgSend Calls"改成NO，然後在用到objc_msgSend前面要加參數的型態，如

objc_msgSend(target, action, selectedDate, origin)

改成 =＞ ((void(*)(id, SEL, NSDate*, id))objc_msgSend)(target, action, selectedDate, origin)

這樣就能解決這error了

objc_msgSend()報錯Too many arguments to function call ,expected 0,have2

Too many arguments to function call, expected 0, have 3
