objective-c - 如何使属性在 InterfaceBuilder (Xcode) 中可见

Question

我创建了一个CustomComponentDataSource将数据传送到CustomComponent.

@protocol CustomComponentDataSource <NSObject>
- (NSUInteger)numberOfBlocksInView:(CustomComponent *)customComponent;
...
@end

@interface CustomComponent : NSView
...
@property id <CustomComponentDataSource> dataSource;
...
@end

是否可以使该dataSource属性可见并准备好在 XCode Interface Bulder 中链接？

Answer 1

将其声明为IBOutlet：

@property IBOutlet id <CustomComponentDataSource> dataSource;
