adding uiview as a subview to the main view

Question

i want to add an UIView for small size as a subview to existing view.

i have a UIViewController pushed with a nib name which is the main vi

Answer 1

UIView *view = [[UIView alloc] init];

Answer 2

UIView needs to be alloc'ed and init'ed with a frame:

CGRect frame = CGRectMake(x, y, width, height); // Replacing with your dimensions
UIView *view = [[UIView alloc] initWithFrame:frame];

Answer 3

To add something (rather important) to the answers above;

CGRect frame = CGRectMake(x, y, width, height); // Replacing with your dimensions
UIView *view = [[UIView alloc] initWithFrame:frame];

Then, you want to actually add it to the superview (assuming the view is self.view)

[self.view addSubview:view];
