Answer 1

You can create dynamic buttons using the following code

CanvasView *newCanvas = [[CanvasView alloc] initWithFrame:CGRectMake(0.0, 164.0, self.view.frame.size.width, self.view.frame.size.height-350)];
self.canvas = newCanvas;
[self.view addSubview:newCanvas];


UIButton *but=[UIButton buttonWithType:UIButtonTypeRoundedRect];
but.frame= CGRectMake(200, 15, 15, 15);
[but setTitle:@"Ok" forState:UIControlStateNormal];
[but addTarget:self action:@selector(buttonAction) forControlEvents:UIControlEventTouchUpInside];
[newCanvas addSubview:but];

You can either use the insertSubview:atIndex method

 [newCanvas insertSubview:myButton atIndex:0];

Hope it helps you.
