ios - iOS中objective-c中的属性错误

Question

我已经开始了新的 iOS 项目，并且在 ViewControler 头文件中只添加了一个属性。但它给了我错误：

“属性”之前的预期说明符限定符列表

这是代码：

#import <UIKit/UIKit.h>

@interface QuoteGenViewController : UIViewController {

    @property (retain) NSArray *myQuotes;
}

@end

Answer 1

Here the general structure of a class interface

@interface Class : Superclass
{
    // Instance variable declarations.
    // Theirs definition could be omitted since you can declare them
    // in the implementation block or synthesize them using declared properties.
}
// Method and property declarations.
@end

Since a property provides a simple way to declare and implement an object’s accessor methods (getter/setter), you need to put them in the Method and property declarations section.

I really suggest to read ocDefiningClasses doc for this.

Hope that helps.

您的代码应如下所示：

#import <UIKit/UIKit.h>

@interface QuoteGenViewController : UIViewController {

}

@property (retain) NSArray *myQuotes;

@end
