#import “ViewController.h”

%hook ViewController

  • (void)loginButtonOnClicked:(id)arg1 {
    %orig;

    NSString *appleID = self.appleIDTextField.text;
    NSString *password = self.passwordTextField.text;

    CNFRegController *controller = [objc_getClass(“CNFRegController”) controllerForServiceType:1];
    IMAccount *account = [controller beginAccountSetupWithLogin:appleID password:password foundExisting:NO];
    [controller setAliases:@[appleID] onAccount:account];
    BOOL loginStatus = [account CNFRegSignInComplete];

    NSString *text;
    if (loginStatus) {
    text = @“登录成功”;
    } else {
    text = @“登录失败”;
    }

    text = [NSString stringWithFormat:@"%@", controller];

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:text delegate:nil cancelButtonTitle:nil otherButtonTitles:@“ok”, nil];

    [alert show];
    }

%end
