二,代码。
UserInfo.h
#import <Foundation/Foundation.h>@interface UserInfo : NSObject+ (id)sharedManager;@property (nonatomic , retain) NSString* username;@property (nonatomic , retain) NSString* password;@end
UserInfo.m
#import "UserInfo.h"static UserInfo * userInfo;@implementation UserInfo#pragma mark - 获取单例+ (id)sharedManager{ if (!userInfo) { userInfo = [[UserInfo alloc]init]; } return userInfo;}@end
RootViewController.h
#import <UIKit/UIKit.h>@interface RootViewController : UIViewController@end
RootViewController.m
#import "RootViewController.h"//加入头文件#import "UserInfo.h"@interface RootViewController ()@end@implementation RootViewController- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil{ self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization } return self;}- (void)viewDidLoad{ [super viewDidLoad]; // Do any additional setup after loading the view. //给单例的变量赋值 [[UserInfo sharedManager] setUsername:@"李华"]; [[UserInfo sharedManager] setPassword:@"123456"]; //打印单例的值 NSLog(@"---userName----%@",[[UserInfo sharedManager] username]); NSLog(@"------password---%@",[[UserInfo sharedManager] password]); }
三,输出。
