tap on uitextfield and crashing

I have two UIViewController class.(with names:RootViewController & SecondViewController)

I add SecondViewController in FirstViewController with this code :

SecondViewController *secondView = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];
[self.view addSubview:secondView.view];

So I create one UITextField in SecondViewController with code:

@interface SecondViewController : UIViewController <UITextFieldDelegate>
@property (nonatomic,strong) UITextField *text1;
@end

@implementation SecondViewController
@synthesize text1;

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor yellowColor];
    self.view.frame = CGRectMake(0, 200, 320, 300);

    text1 = [[UITextField alloc] initWithFrame:CGRectMake(20,70,180, 32)];
    text1.textAlignment = NSTextAlignmentRight;
    text1.layer.borderWidth = 1.0f;
    text1.layer.borderColor = [[UIColor grayColor] CGColor];
    text1.autocorrectionType = UITextAutocorrectionTypeNo;
    text1.delegate = self;
    [self.view addSubview:text1];
}
- (IBAction)BackgroundTap:(id)sender {
    [text1 resignFirstResponder];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [text1 resignFirstResponder];
    return YES;
}

Now My Problem Here : when run app and click on my textfield app crashed!!! why??? when app crashed show my this code :

#import <UIKit/UIKit.h>

#import "AppDelegate.h"

int main(int argc, char * argv[])
{
    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}

this is my error :

Your view controller containment is done incorrectly:

SecondViewController *secondView = [[SecondViewController alloc]initWithNibName:@"SecondViewController"
                                                                         bundle:nil];
[self addChildViewController:secondView]; //Assuming self is view controller
[self.view addSubview:secondView.view];
[secondView didMoveToParentViewController:self];
