or on a combination of objects. The former is called single dispatch and is directly supported by common object-oriented languages such as C++, Java, Smalltalk, Objective-C, Swift, JavaScript, and Python. In these and similar languages, one may call a method for division with syntax ...
In Swift 3 and earlier,dynamicalso implied@objc. New in Swift 4,dynamiconly means dynamic dispatch and says nothing about Objective-C visibility. However, there’s no such thing as Swift dynamic dispatch; we only have the Objective-C runtime’s dynamic dispatch. That means you can’t have...
Swift中也有dynamic关键字,它可以用于修饰变量或函数,它的意思也与OC完全不同。它告诉编译器使用动态分发而不是静态分发。OC区别于其他语言的一个特点在于它的动态性,任何方法调用实际上都是消息分发,而Swift则尽可能做到静态分发。 因此,标记为dynamic的变量/函数会隐式的加上@objc关键字,它会使用OC的runtime机制。
@objc makes things visible to Objective-C code. You might need this for setting up target/action on buttons and gesture recognizers. dynamic opts into dynamic dispatch. You might need this for KVO support or if you‘re doing method swizzling. The only way to do dynamic dispatch currently i...
