[iOS] 警告訊息框 ＋ 帳號密碼輸入

練習到這部分又覺得這個功能很實用，於是又放上來了 。

其實跟昨天的那篇沒有差太多，但就是進階版本。（詳情可以看 警號訊息框 ）

先放上完成圖 ＆ code

一樣是在viewcontroller.m裡面做修改喔！

詳細的備註程式裡面有寫完整了，如果還不會也是可以發問

@implementation ViewController

- (void)viewDidLoad {

    // Do any additional setup after loading the view, typically from a nib.

- (void) viewDidAppear:(BOOL)animated

{

    //create a UIAlertController

    UIAlertController *alertController = [UIAlertController

                                          alertControllerWithTitle:@"Title" message:@"message" preferredStyle:UIAlertControllerStyleAlert];

    //declare a "cancel" button

    UIAlertAction *cacelAction = [UIAlertAction actionWithTitle:@"cancel" style:UIAlertActionStyleDefault handler: ^(UIAlertAction *action){

        [self dismissViewControllerAnimated:YES completion:nil];}];

    //declare a "login" button

    UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"login" style:UIAlertActionStyleDefault

        handler:^(UIAlertAction *action){

            NSString *uid = ((UITextField *) [alertController.textFields objectAtIndex:0]).text;

            NSString *pwd = ((UITextField *) [alertController.textFields objectAtIndex:1]).text;

            NSLog(@"account = %@",uid);

            NSLog(@"password = %@",pwd);}];

    //create first textfield

    [alertController addTextFieldWithConfigurationHandler:^(UITextField *textField)

    {textField.placeholder = @"Login";}];

    //create second textfield

    [alertController addTextFieldWithConfigurationHandler:^(UITextField *textField)

    {textField.placeholder = @"password";

        textField.secureTextEntry = YES;}];

    

    [alertController addAction:cacelAction];

    [alertController addAction:okAction];

    

    [self presentViewController:alertController animated:YES completion:nil];

                                  

}

@end

就是這樣囉！
