Swift Object-c calls each other

Let's take a look at the swift call Object-c

First we create a OC class

At the last step, I found a confirmation box, click Yes the system will generate a conversion bridge for Swift and OC.

His naming rules are the project name-bridging-header.h This is the system generated by our direct use.

Next we add a method to the OC class that we just created

#import <Foundation/Foundation.h> @interface testswift2oc:nsobject-(void) testocstr; @end

Implementation method

#import "TestSwift2OC.h" @implementation testswift2oc-(void) testocstr{    NSLog (@ "This is the OC Method");} @end

Then we add a statement to the system-generated file testswiftoc-bridging-header.h.

#import "TestSwift2OC.h"

Well, we can call it in swift, try it.

        var testswift2oc=testswift2oc ()        testswift2oc.testocstr ()

Did it come out already?

Now let's take a look at the OC call Swift

We create a new swift to define a method

Import Uikitclass testoc2swft:nsobject {    func testswftstr () {        println ("This is the Swift method")    }}

Then we first import a header file in the OC class that needs to invoke the Swift class

Project Name-swift.h (this is automatically generated by the system)

Look at the code

#import "Testswiftoc-swift.h"

Then we call in OC

    TESTOC2SWFT *testoc2swift=[[testoc2swft Alloc]init];    [Testoc2swift TESTSWFTSTR];

The call is ready.
