iOS項目-連絡人清單

標籤：

一，項目介紹

首先，簡單介紹一下這個項目的效果

進入程式，首先是登入頁面

登入頁面用到 NSUserDefault 記住登入密碼

 

然後是

 

然後是登入跳轉，用到MBProgressHUD

接著是連絡人清單 是一個UITableView

 

點擊+ 進入新增連絡人...頁面

點擊每行連絡人 進入編輯介面

 

 

點擊登出，彈出UIAlertController

 

 

 

 

二，進入代碼

 

首先 在SB中構建視圖的架構

 

 

 

然後建立幾個對應的控制器，並做好子類連結

 

 

然後實現 登入介面

首先添加觀察者，監視textfield的值的變化

 

    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(textChange) name:UITextFieldTextDidChangeNotification object:self.nameTxtFiled];

    

    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(textChange) name:UITextFieldTextDidChangeNotification object:self.pwdTextField];

    

 設定

NSUserDefaults

記住密碼

設定事件

 

-(void)textChange

{

    self.loginBtn.enabled = self.nameTxtFiled.text.length&&self.pwdTextField.text.length;

 

}

 設定每一個segwe的跳轉

 

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    if ([segue.identifier isEqualToString:@"id"]) {

        ContactTableViewController *contactVC = segue.destinationViewController;

        contactVC.title = [NSString stringWithFormat:@"%@的連絡人清單",self.nameTxtFiled.text];

    }

 

 

}

 點擊事件

 

- (IBAction)loginClick {

    if (![self.nameTxtFiled.text isEqualToString:@"dsn"]) {

        [MBProgressHUD showError:@"使用者名稱錯誤"];

        return;

    }

    if(![self.pwdTextField.text isEqualToString:@"123"])

    {

        [MBProgressHUD showError:@"密碼錯誤"];

        return;

    }

    

    [MBProgressHUD showMessage:@"正在登陸，請等待...."];

    

    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

        [MBProgressHUD hideHUD];

        [self performSegueWithIdentifier:@"id" sender:nil];

    });

    

    

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

    [defaults setObject:self.nameTxtFiled.text forKey:usernameKey];

    [defaults setObject:self.pwdTextField.text forKey:userpassKey];

    [defaults setBool:self.switchbTN.on forKey:switchKey];

    

    [defaults synchronize];

    

    

}
