在Objective-C中使用Swift,步驟類似:

1、首先建立一個Objective-C的項目:

2.添加一個Swift的類檔案:

3、點擊Next,彈出一個對話方塊,選擇YES

4、產生一個YourProject-Bridging-Header.h檔案,在本項目中產生的檔案如:

5、在SwiftClass建立類如下:

  import Foundation   class SwiftTest : NSObject {    func test()->NSString{    return "test"   } }

6、在ViewController調用SwiftTest類如下:

  #import "ViewController.h"  #import "ObjectiveTest-Swift.h"  //這裡注意和項目名稱一致  "YourProject-Swift.h"

7、import之後一定要先編譯一次,否則編譯出錯。
8、編譯之後就可以在類裡面調用了如下:

    - (void)viewDidLoad {        [super viewDidLoad];      // Do any additional setup after loading the view, typically from a nib.       SwiftTest *tests = [SwiftTest new];       [tests test];  }
