UIScrollView error in iOS - ios

Question

I am new to UIScrollView. I don't know how to add buttons with them. In my app, I need a button in horizontal view. But when I tried to create the UIScrollView programatically, its not working. It is throwing some errors. pls help me
I tried to implement this using storyboard too, but failed as I dont how to connect them both using the viewDidLoad.
this is the code I have used so far:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.layerPosition = self.toplayer.frame.origin.x;
UIScrollView *scrollview =[[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
scrollview.showsHorizontalScrollIndicator=YES;
scrollview.userInteractionEnabled=YES;
scrollview.scrollEnabled=YES;
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(newView:) forControlEvents:UIControlEventTouchDown];
[button setTitle:#"Excavations",#"Concrete",#"Framing",#"Insulation" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[self.view addSubview:scrollview];
scrollview.contentSize = CGSizeMake(320,960);
}
if I am doing wrong pls tell me the correct procedure to do it.
thanks

Answer 1

I can see just one error in your code now:
[button setTitle:#"Excavations",#"Concrete",#"Framing",#"Insulation" forState:UIControlStateNormal];
setTitle: expect just one string, try this:
[button setTitle:#"Excavations" forState:UIControlStateNormal];
You probably want to add this button thou your scroll view so you need to call:
[scrollview addSubview:button];
It should help, if not post your error.
I assume you want to pass UIControlEventTouchUpInside instead UIControlEventTouchDown as a button control event.

try this .it will work
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.layerPosition = self.toplayer.frame.origin.x;
UIScrollView *scrollview =[[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
scrollview.showsHorizontalScrollIndicator=YES;
scrollview.userInteractionEnabled=YES;
scrollview.scrollEnabled=YES;
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(newView:) forControlEvents:UIControlEventTouchDown];
[button setTitle:#"Excavations" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[self.view addSubview:scrollview];
scrollview.contentSize = CGSizeMake(320,960);
}
