Live Bytes of app reaches above 1 GB and simulator shows blank screen

Question

I am working in a big project. There was no problem till last hour. Suddenly my app's live bytes keeps on increasing and it touches above 1 GB and I can't even identify where the problem is. I have searched and found this but its for overall bytes not for live bytes.

I got the following error after five minutes:

xxxxxx(1456,0x252d1a8) malloc: *** mach_vm_map(size=8388608) failed (error code=3)
*** error: can't allocate region

Here is a screenshot of Instruments and you can see the live bytes reaches 1 GB.

I've tried the following steps

1. Reset the contents and settings of simulator
2. Delete Xcode full application files
3. Delete all derived files and clean trash fully
4. Re-install Xcode

To be more correct error found in this lines

- (void)viewDidLoad
{
    [super viewDidLoad];

    [UserNameTxtFld setBackgroundColor:[UIColor colorWithRed:242.0f/255.0f green:245.0f/255.0f blue:245.0f/255.0f alpha:1.0]];

    UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, UserNameTxtFld.frame.size.height)];

    UserNameTxtFld.leftView = paddingView;

    UserPasswordFld.leftView =paddingView;

    //Set Splash screen

        CGSize result = [[UIScreen mainScreen] bounds].size;
        if(result.height == 480)
        {
            // iPhone Classic
            NSLog(@"iphone 4");

            if(IS_RETINA)
            {
                NSLog(@"Yes retina Display");
                splashScreenImage.image =[UIImage imageNamed:@"splash_640x960.jpg"];
                [visiblePassword setBackgroundImage:[UIImage imageNamed:@"eye_640x960.png"] forState:UIControlStateNormal];

            }
            else
            {
                NSLog(@"Not retina Display");
                splashScreenImage.image =[UIImage imageNamed:@"splash_320x480.jpg"];
                [visiblePassword setBackgroundImage:[UIImage imageNamed:@"eye_320x480.png"] forState:UIControlStateNormal];
            }
        }
        if(result.height == 568)
        {
            // iPhone 5
            NSLog(@"iphone 5");
            splashScreenImage.image =[UIImage imageNamed:@"splash_640x1136.jpg"];
            [visiblePassword setBackgroundImage:[UIImage imageNamed:@"eye_640x1136.png"] forState:UIControlStateNormal];
        }
    }


}

Nothing's worked. Can any one could say what the problem is?

Answer 1

I have seen your code in this Link

As per your given code you have used same code multiple time.

    UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, UserNameTxtFld.frame.size.height)];

    UserNameTxtFld.leftView = paddingView;

    UserNameTxtFld.leftViewMode =UITextFieldViewModeAlways;

    UserPasswordFld.leftView =paddingView; // this is wrong(can't use it again)
    UserPasswordFld.leftViewMode =UITextFieldViewModeAlways;

You can't use same padding view again. You have to alloc it again for UserPasswordFld field. Take another padding view and use it then it will work.
