Swift框架< - > ObjC互操作

Question

I've got a dylib framework with some UIView subclasses made in swift which I've done to use the new @IBDesignable and @IBInspectable stuff.

So lets say I've got a UITextField subclass in there named MyTextField.swift like this:

MyTextField.swift

@IBDesignable class MyTextField: UITextField {

    // some properties etc.
    // content is irrelevant   
}

Now it compiles and works well in InterfaceBuilder so far so good. But what I need to do is import this special subclass into my Objective C implementation of the controller to set a property in code at runtime.

The framework (named myViews ) has a header called myViews.h which I am able to import into the controllers header like this:

MyViewController.h:

@import myViews;

#import <UIKit/UIKit.h>

#import "myViews.h"

@interface MyViewController : UIViewController

@property(weak, nonatomic) IBOutlet MyTextField *txtName; // <-- This is the problem!

@end

This is where I'm stuck! So the class MyTextField is unknown from the imported headers. The myViews.h was automatically generated. I've tried to import the bridging-headers in there without success.

myViews.h:

#import <UIKit/UIKit.h>

//! Project version number for myViews.
FOUNDATION_EXPORT double myViewsVersionNumber;

//! Project version string for myViews.
FOUNDATION_EXPORT const unsigned char myViewsVersionString[];

// In this header, you should import all the public headers of your framework
// using statements like #import <myViews/PublicHeader.h>

#import <myViews/MyTextField-Swift.h> // <-- This is what I've tried to import here which doesn't work as well.

Hope anybody may help me out. Thanks in advance.

In your objective-c class, try importing your swift module like this:

#import "<ModuleName>-Swift.h"

Where ModuleName is the name of the module containing the swift code
