IOS UserModel创建

之前一直是NSDictionary党，拿到服务器数据存储到字典后，哪里用到哪里取值。这么做虽然方便，然后可读性差，尤其一段时间后回头做修改，会很难受。于是学着创建model来管理数据。

用户模型创建了两个类：User和UserModel。
User:
使用NSUserDefaults来保存用户信息，提供一些简单方法，包括保存用户信息，清理用户信息，获取一些指定的数据如头像、名字等，登陆状态的判断。

UserModel：
1.处理数据访问，比如登陆获取用户信息，上传头像；
2.把字典中需要的值转成类的属性来保存。

User.h:

#import <Foundation/Foundation.h>
@class UserModel;
@interface User : NSObject

+ (void)saveProfile:(UserModel *)userModel;
+ (NSString *)getMemberID;

+ (void)updatePhoto:(NSString *)photo;

+ (void)loginOut;
+ (BOOL)isLogin;
@end

User.m


#import "User.h"
#import "UserModel.h"

static NSString *const kMemberID = @"memberID";
static NSString *const kBindMobile = @"bindMobile";
static NSString *const kPhoto = @"photo";
static NSString *const kTrueName = @"trueName";
static NSString *const kSex = @"sex";
static NSString *const kEmail = @"email";
static NSString *const kMemberLevel = @"memberLevel";
@implementation User

+ (void)saveMemberID:(NSString *)memberID andBindMobile:(NSString *)bindMobile andPhoto:(NSString *)photo andTrueName:(NSString *)trueName andSex:(NSString *)sex andEmail:(NSString *)email andMemberLevel:(BOOL)memberLevel{
    
    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    [userDefaults setObject:memberID forKey:kMemberID];
    [userDefaults setObject:bindMobile forKey:kBindMobile];
    [userDefaults setObject:photo forKey:kPhoto];
    [userDefaults setObject:trueName forKey:kTrueName];
    [userDefaults setObject:sex forKey:kSex];
    [userDefaults setObject:email forKey:kEmail];
    [userDefaults setBool:memberLevel forKey:kMemberLevel];
    
    [userDefaults synchronize];
}

+ (void)saveProfile:(UserModel *)userModel{
    [User saveMemberID:userModel.memberID andBindMobile:userModel.bindMobile andPhoto:userModel.photo andTrueName:userModel.trueName andSex:userModel.sex andEmail:userModel.email andMemberLevel:userModel.memberLevel];
}

+ (NSString *)getMemberID{
    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    return [userDefaults objectForKey:kMemberID];
}

+ (void)updatePhoto:(NSString *)photo{
    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    [userDefaults setObject:photo forKey:kPhoto];
    [userDefaults synchronize];
}

+ (void)loginOut{
    [User saveMemberID:@"" andBindMobile:@"" andPhoto:@"" andTrueName:@"" andSex:@"" andEmail:@"" andMemberLevel:0];
}

+ (BOOL)isLogin{
    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    NSString *memberIDString = [userDefaults objectForKey:kMemberID];
    return memberIDString.length>0;
}
@end

    } else {
        return CGSizeMake(800 * width / height, 800);

举个例子，我现在要作登陆操作：
LoginViewController.m

- (void)doRightButtonAction{
    MBProgressHUD *HUD = [[MBProgressHUD alloc] initWithView:self.view];
    HUD.labelText = @"正在登陆";
    [HUD show:YES];
    [self.view addSubview:HUD];
    
    self.loginModel = [UserModel new];
    NSDictionary *parameter = @{@"mobile":@"18758363317",@"password":@"111111"};
    [self.loginModel loginWithParameter:parameter success:^(NSString *successMessage) {
        HUD.mode = MBProgressHUDModeText;
        HUD.labelText = successMessage;
        [HUD hide:YES afterDelay:1.5];
    } failure:^(NSString *failureMessage) {
        HUD.mode = MBProgressHUDModeText;
        HUD.labelText = failureMessage;
        [HUD hide:YES afterDelay:1.5];
    }];
    
}
