My adBannerViewdoesn't appear in my UIScrollView.
I suppose it is because user doesn't visualize the ad if he does not scroll. So Apple does not allowed it.
Is it right ? I have not found anything on the subject on the web.
Cheers.
You can't place an ADBannerView inside an UIScrollView such as a UITableViewController
You can however use a UIViewController and add, on top of this view, an ADBannerView and UIScrollView.

I am new to mac application development, here i want to do expand and collapse view in my custom view(NSView)
here the sample image
How can i achieve these kind of collapse and expand cell in NSViewController not in NSWindow...
Is it possible using NSTableView?
I know its a simple question but i facing problem.
Please suggest me some sample code or links..
Thanks
Collapsing / expanding can be implemented by adjusting auto layout constraints in the action method of the disclosure triangle button.
#property (nonatomic, weak) IBOutlet NSLayoutConstraint *moreInfoBoxHeight;
[[self.moreInfoBoxHeight animator] setConstant:75];
Apple has sample code using NSStackView at https://developer.apple.com/library/mac/samplecode/InfoBarStackView/Introduction/Intro.html
The view at the picture given is NSOutlineView. It is the NSTableView subclass.
Look at the Apple reference page and Outline programming topics.
I have UiTableView containing some data, and I want to scroll the UiTableViewCells horizontally to the left or right to show some UiButtons that act some action relatif to the content of the cell.
How Can I do this?
I'm thinking in creating custom cell, and putting a scrollView in it, May this did the trick?
There is a tutorial for this at http://idevrecipes.com/2011/04/14/how-does-the-twitter-iphone-app-implement-side-swiping-on-a-table/ with sample code. He is using a UISwipeGestureRecognizer to trigger an animation that pushes the cell off the screen.
You could use a swipe gesture recognizer attached to your cell.
You can add a UIScrollView to the contentView of a UITableViewCell. If you want to scroll the content using buttons, simply overlay the UIScrollView with buttons and make them call the various scrolling methods of UIScrollView.
Nested UIScrollView (UITableView inherits from UIScrollView) are quite clever about detecting touch conflicts and resolving the users intended gesture.
https://github.com/JonasGessner/JGScrollableTableViewCell might be what you're looking for. It implements this using a UIScrollView inside the cell (just like the iOS 7 mail app).
(Yes the answer is a bit late, but it's never too late! :P)
I've been searching for some time for an answer on this problem:
How can I keep the scrollbars on my UIScrollView and UIWebview visible? So that the user knows he can scroll up or down. (like in firefox or any other browser so without touching the scrollvie first)
I read on some sites that it wasn't possible, so my other question would be:
Is there a way to add a "scrollbar" to a scrollview or webview?
Thank you very much
Maybe you could use this:
flashScrollIndicators
It won't show the scrollbar all the time, but it just flashes when the view is loaded.
Edited: Other solution:
In your view didload, you make a scrollview of you webview like this:
UIScrollview *scrollview = [webview.subviews objectAtindex:0];
you have to set the delegate of the scrollview on self:
scrollview.delegate= self
in your .h file you add
When you place in your .m file you can use:
-(void)ScrollviewDidscroll:...
(I don't know if it works when you have multiple scrollviews)
Yes you can try adding a custom view ( can be image view) on top the scrollbar. You will have to monitor the contentOffset and contentSize to know where you are. Based on this information, you can position your custom scroll bars.
It may be a dumb question, but I can't find an answer to this ...
I have an UIScrollView and inside a number of UIButtons.
When I press a button, I want to know the screen location of the button. If I use button.frame it gives me the position inside UIScrollView, which is normal.
How can I find x and y relative to screen of the button pressed?
Thanks in advance.
Your objection was right- instead, use
- (CGPoint)convertPoint:(CGPoint)point toView:(UIView *)view
from UIView, like
[button.superview convertPoint:button.frame.origin toView:nil];
Not tested, but I believe that should work. Also see iPhone - Get Position of UIView within entire UIWindow
For swift:
let pointXY:CGPoint = (button.superview?.convert(button.frame.origin, to: nil))!
print("button pointXY: \(pointXY.debugDescription)")
I created UIImageView with the help of Interface Bulder. Now I want to place label inside it (as its subview). In code I can type something like: [myUIImageView addSubview:myUILabel]; But can I do it with the help of IB? I found the solution for UIView, but can't find something similar for UIImageView.
You cannot add a subview to UIImageView in interface builder for reasons only known to Apple! You are right in saying that you can addSubview programmatically, but then, the overhead of setting autoresizing masks and placements of subviews should all be handled in code, which is cumbersome.
So there is an easy workaround. Instead of dragging an instance of UIImageView in the nib, just drag a UIView and change its class to UIImageView from UIView (cmd+4 option of inspector). The only difference you find in the nib for default imageView instance and your new UIImageView subclass instance is: you cannot set image to your new imageView from nib (cmd+1 option). So, in the -viewDidLoad method of its appropriate viewController, set image to this outlet of UIImageView.
By doing so, you are free to add subviews to your "now UIImageView" instances in interface builder, which is much easy.
I would like to add answer.
While it sucks you cannot add subview to UIImageView, you can get the same effect by incorporating UIView with transparent (clear color) background.
Then put the UIImageview BEFORE it.
So the UIView has the subviews and the UIImageview is the background of the UIView.
I think that's apple's intent.
Here is a screenshot:
Here is the result:
Don't forget to set background as clear color
Now if someone could actually point me to a tutorial how to do this it'll be great. I spent hours doing it the checked answered way. The checked answer is a fine answer but very unintuitive because you can't see your background image clearly while working. I think mine is the proper way to do so.
In latest XCode(4.5) there is an option to drag and drop the required controls to the parent.
It is quite easy.
Attached screen shot for the same. I dragged the Label/TextField and Button to UIImageView
Use this code:
UIImage *image = [UIImage imageNamed:#"background.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
[self.view insertSubview:imageView atIndex:0];
(replace background.png with image) (replace atIndex:0 with whatever place in the .index root you want to insert the image and your off.
