iOS Subviews are getting placed on different position for the same Coordinate

[AbhishekApple]

Subviews are getting placed on different position on mainView for the same Coordinates
I have created a toolbar in IB and other through code,........
while adding both the tool bars on the same coordinates they are being placed on different position... ???????
Plz any one can suggest....

@synthesize toolBar;

- (void)viewDidLoad {
    [super viewDidLoad];
	UIToolbar *tbl = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 210 ,770 , 40)];
	[tbl setBarStyle:UIBarStyleBlack];
	[self.view addSubview:tbl];
	
	toolBar.frame= CGRectMake(0, 210 ,770 , 40);
	[self.view addSubview:toolBar];
}

But if i create both the toolbar through code then they occupy the same position....

Actually i have Scrollview created Through code and want to add toolbar (created in IB) at the bottom of scrollview... but it is not getting placed on required position....
