Cocoa 绑定和宏

我在 Interface Builder 中有一堆绑定。当我想访问它时，我必须这样做，例如：

[[NSUserDefaults standardUserDefaults] integerForKey:@"bINDDPagesTag"]

并且我必须为其他绑定执行至少 20 次...那么，如果我使用 #define 来正常吗？这些绑定是这样的：

#define kINDDPagesTag [[NSUserDefaults standardUserDefaults] integerForKey:@"bINDDPagesTag"]
#define kINDDRange [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDRange"]
#define kINDDBleedTop [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDBleedTop"]
#define kINDDBleedBottom [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDBleedBottom"]
#define kINDDBleedInside [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDBleedInside"]
#define kINDDBleedOutside [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDBleedOutside"]
#define kINDDSendData [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDSendData"]

它工作得很好，但我应该使用这种方式吗？我还有更好的办法吗？谢谢！

I have a bunch of bindings in Interface Builder. When I want to access it, I have to do this, for example:

[[NSUserDefaults standardUserDefaults] integerForKey:@"bINDDPagesTag"]

and I have to do it for other bindings at least 20 times...so, is it normal if I using #define for these bindings like this:

#define kINDDPagesTag [[NSUserDefaults standardUserDefaults] integerForKey:@"bINDDPagesTag"]
#define kINDDRange [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDRange"]
#define kINDDBleedTop [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDBleedTop"]
#define kINDDBleedBottom [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDBleedBottom"]
#define kINDDBleedInside [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDBleedInside"]
#define kINDDBleedOutside [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDBleedOutside"]
#define kINDDSendData [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDSendData"]

It works perfectly, but should I use this way? I there a better way?
Thanks!

我从来没有这样做过，但我认为你的方法没有理由行不通。但是，我认为创建静态实用程序类可能更灵活且更易于维护，例如：

@interface InterfaceConstants : NSObject {
}
+ (int)pagesTag;
+ (id)range;
//etc.
@end

@implementation InterfaceConstants
+ (int)pagesTag {
    return [[NSUserDefaults standardUserDefaults] integerForKey:@"bINDDPagesTag"];
}
+ (id)range {
    return [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDRange"];
}
//etc.
@end

I've never done it that way, but I see no reason why your approach wouldn't work. However, I think creating a static utility class may be a bit more flexible and more maintainable, like:

@interface InterfaceConstants : NSObject {
}
+ (int)pagesTag;
+ (id)range;
//etc.
@end

@implementation InterfaceConstants
+ (int)pagesTag {
    return [[NSUserDefaults standardUserDefaults] integerForKey:@"bINDDPagesTag"];
}
+ (id)range {
    return [[NSUserDefaults standardUserDefaults] objectForKey:@"bINDDRange"];
}
//etc.
@end
