iOS - 无法访问swift类的静态方法

Question

I want to access Swift code in Objective-c .

I have written one class in swift which contains static method. I want to access that Static Method in objective C Class.

Here is Class declaration:

@objc class LocalizedResource: NSObject {

    /*!
    * @discussion This function will get localize string for key

    * @param key Localize key
    * @return String for locaized key
    * @code LocalizedResource.getStringForKey(key);
    */
    static func getStringForKey(key:String) -> String    {
        let frameworkBundle = NSBundle.mainBundle()
        let value = frameworkBundle.localizedStringForKey(key, value: nil, table: nil)
        return value;
    }
}

I have made following settings for it:

1. Product Module Name : MyProject
2. Defines Module : YES
3. Embedded Content Contains Swift : YES
4. Install Objective-C Compatibility Header : YES
5. Objective-C Bridging Header : $(SRCROOT)/MySources/SwiftBridgingHeader.h

Also I have added @Obj before my class declaration in Swift class.

I have import MyProject-Swift.h in the .m file where I want to access that method.

But when I am trying to access it, it is not allowing me to access that static method.

Is any one having solution for it? Is there something missing?

Thnaks.

Answer 1

注意在Swift 4和构建设置swift 3 @objc inference是default ，我们必须明确地将函数标记为@objc ，否则它将不会在Swift桥头中生成类函数。

From your comment:

I am calling this method as follows:

 errorMessage.text = LocalizedResource.getStringForKey(@"TIMED_OUT_ERROR"); 

In Objective-C, the "dot syntax" is used for properties, not for methods. The correct call should be

errorMessage.text = [LocalizedResource getStringForKey:@"TIMED_OUT_ERROR"];
