Buttons on a scrollview

[kampftrinker]

How do i add a button to a scrollview when there is no NIB involved?

below is the code i thought might work, the scrollview part works fine i just can't see the button. any ideas?

-(void)loadview {
self.scrollview1 = [[UIScrollView alloc] init] autorelease];
self.scrollview1.delegate = self;
self.scrollview1.pagingEnabled = YES;
self.scrollview1.showsHorizontalScrollIndicator = NO;
self.scrollview1.showsVerticalScrollIndicator = NO;
self.view = self.scrollView1;

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(100, 60, 100, 30);
button setTitle:@"Click Me!" forState:UIControlStateNormal];
[self.scrollView1 addSubview:button];
}

Thanks
Mick

Can you even see the scrollview? You don't give it a frame anywhere, which could be a problem.

Hi, I can see the scrollview and it works fine.
It's just the button that seems to be a problem.

Thanks

Using your code in a new project, I cannot see the scrollview or the button. Giving it a frame, I can see both the scrollview and the button.

Something to bare in mind as well is that loadView will not work if you are using a XIB.

- (void)loadView {
	
	self.scrollview1 = [[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)] autorelease]; // Dont hard code values in actual app.
	self.scrollview1.delegate = self;
	self.scrollview1.pagingEnabled = YES; 
	self.scrollview1.showsHorizontalScrollIndicator = NO;
	self.scrollview1.showsVerticalScrollIndicator = NO;
	self.view = self.scrollview1;

	UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
	button.frame = CGRectMake(100, 60, 100, 30);
	[button setTitle:@"Click Me!" forState:UIControlStateNormal];
	[button sizeToFit];
	[self.scrollview1 addSubview:button];
}

Hi Harry, thanks for the reply, you are right about the frame that solved the issue. I've tested it without a NIB file and it works, this has highlighted another couple of issues.

My scrollview displays a number of images which i can swipe through. The button moves off screen when i swipe the first image also the button is behind the actual image.

How can i position the button above the image and also stop it scrolling.

Thanks for your help so far.

I would suggest adding the scrollview as a subview to the main view, rather than setting that scrollview as the main view.
Then you would add the button to the main view and not the scrollview. That way it won't scroll and will be on top of the scrollview, providing you add it last.

Thanks for that Harry, it's working now.
