Creating multiple views programmatically

Question

Hello I would like to ask how to create multiple views programmatically and show them on the screen, I have tried this but there is something missing.

int x,y;

x= 0;
y=50;

for (int i=0; i<4; i++)
{
    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(x, y, 300, 100)];

view.backgroundColor = [UIColor redColor];


[self.view addSubview: view];

    y+=40;
}

which method do you use this in ? I'm trying to make multiple UIViews in swift but I thought making it like so would override the same and delete the previous one from superview? — TheBen

int x,y,paddingX,widthOfView,HeightOfView;

x= 0;
y=50;
paddingX = 10;
widthOfView = 100;
HeightOfView = 100;

for (int i=0; i<4; i++){
    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(x, y, widthOfView, HeightOfView)];
    view.backgroundColor = [UIColor redColor];
    [self.view addSubview: view];

    y+= widthOfView + paddingX;
}

Following Code may help to you.

    view.layer.cornerRadius = 5.0f;
    [self.view addSubview: view];
    y+=140; //y for next view should be height of previous view and margin between view

Hello I would like to ask you how can I update the frame size while dragging it i have tried this code : { UITouch *touch = [touches anyObject]; CGPoint thisTouch = [touch locationInView:[touch view].superview]; CGPoint prevTouch = [touch previousLocationInView:[touch view].superview]; CGFloat dx = thisTouch.x - prevTouch.x; if ([touch view].frame.origin.x + dx < -500) { [touch view].frame = CGRectMake([touch view].frame.origin.x + dx, [touch view].frame.origin.y, [touch view].frame.size.width, [touch view].frame.size.height); }
