Objc的class属性

代码-Manager.h文件:

#import <Foundation/Foundation.h>

@interface Manager : NSObject

@property (nonatomic, strong, class, readonly) Manager *sharedManager;

@property (nonatomic, copy, class) NSString *name;

@end

代码-Manager.m文件:

#import "Manager.h"

static NSString *_name = nil;

@implementation Manager

+ (Manager *)sharedManager {
    static Manager *_instance = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _instance = [[self alloc] init];
    });
    return _instance;
}

+ (void)setName:(NSString *)name {
    _name = [name copy];
}

+ (NSString *)name {
    return _name;
}

@end
