ios實現帶有輸入框的AlertView

1,實現一個alertView

    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"" message:@"請輸入Wi-Fi密碼" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"確定", nil];
    alertView.alertViewStyle = UIAlertViewStyleSecureTextInput;
    [alertView show];

2，實現代理方法

#pragma mark - UIAlertViewDelegate
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    UITextField *passwordText = [alertView textFieldAtIndex:0];
//    passwordText.
    NSLog(@"%@",passwordText.text);
    NSLog(@"buttonIndex:%d",buttonIndex);
}
