I want to make photogrid like this app.
I know that I can do this using UIClollectionView or any other demos available in cocoa controls , but the issue of using all these is that i can not move the grid view in any direction i.e i can move only in horizontal or vertical directions but not in z axis direction (i.e scrolling horizontal and vertical directions at the same time).
I want the grid view to move in any directions.
Is there any way to achieve this?
Thanks..

I am using XF and sfchart and I want to detect the zooming direction and set the zoom mode based on it, I mean if the user starts zooming vertically I want to zoom mode to be set on Y axis and when they zoom horizontally I want to set it on X axis. Is there anyway to detect the zoom direction?
Usually items of iCarousel are displayed downside tilted. I want the change with upside tilted.
I got the code at github
and the iCarousel with options was nearest to my requirement.But it was for in same Y level Where I need to tilt it upwards.I changed its angle but it gets overlapped which is also not required. I simply just want to tilt the views upwards rather than downwards.
I have adjust tilt and spacing value of converflow type of iCarousel
Is there any idea to acquire this?
UPDATE:
I tried to use Cylindrical type in the example.And that matches the tilt effect upward as i want. But if I decrease the space it all overlaps and images are getting overlapped. Which I don't want I want images to get behind of each other
I am trying to created a vertical menu (on the left side of the screen) which I can display and hide using a gesture recognizer.
I have found a post similar to this which helped slightly, but all it did was rotate the UIToolBar to a vertical position without changing the width or position.
If anyone has succesfully created something similar to this and is willing to help I would greatly appreciate it!
Also, if anyone can point me in the right direction possibly to some sample code I would like that as well.
You could do this with a UIToolBar by applying a 90 degree rotation transform, and then having all your icons rotated 90 degrees to match - you can change the width and position simply by adjusting the UIToolBar frame. However, you will need to create your own toolbar to do this rather than using the built-in one you get with a navigation controller.
Another option is simply to roll it yourself: this will allow you more customisation, so is perhaps the better option. There are a number of third-party implementations of varying types, some based off the current Facebook App side-bar, a good place to start looking is http://cocoacontrols.com - they are of varying quality.
On the other hand, it wouldn't be too difficult to roll your own, so that's a good option to consider.
I trying to figure out how to create a Custom Map like the following:

I just don't know where to start from, do I use UIWebView or MapKit?
Any help will be appreciated.
Thanks
What we did in our app is use a UIImageView on a UIScrollView. You need to take a screenshot of the object you will map on the google-map and precisely draw your overlay over it. Also you need to take the top left coordinate and bottom right coordinate of the screenshot you took from the map. Then put the overlay image inside an imageview, image view on scrollview, and scale your coordinate system on the scrollview with the coordinates you took from the map. Now you can precisely plot POI-s on your overlay. A note: The first thing we did is we overlaid the g-map with custom image view but it was really slow when scrolled, so don't even try it. Good luck with coding.
[EDIT] you take a large screenshot of an area on google map like this

I'm building a cell-based game that essentially works like dominoes: you start with one tile in the center, then connect additional tiles to it that can branch out in all directions. I have my game table all set up and working great... now I just need to make it scroll to accommodate the expanding content.
So, this doesn't seem to fit easily into a UIScrollView's built-in behavior. For one thing, cells expand in all directions – potentially going into the negative coordinate space of the UIScrollView. As far as I can tell, UIScrollView does not allow an actual CGRect with size AND origin to be defined for the scrolling content area. It appears you can only define a width and height for the content area that extends from point (0,0). Is this true, or am I missing something?
Assuming my understanding of the content area limitations are correct, how would one ideally handle this problem? My go-to idea would be to shift all subviews into positive coordinate space as the game board expands, then update the ScrollView's contentOffset property to counter the shift and make the transition invisible. I just want to make sure I'm not reinventing an inferior wheel before I start developing this.
Thanks in advance for any and all ideas!
I believe your idea is the good one, every time a tile is added, you may need to adjust your content view in order to be able to center on the tile that just was added.
Hence if this is "backward" (-x or -y) and your on top of your view (or nearly), you'll have to extend your contentView (surely the same way you do for +x, +y) and thus, adjust every of your tiles with the translation you did to your contentView's down-right corner.
Following up... yep, that did it. I set up the display so that it redraws the grid of cells from the upper-left corner. Whenever a new row or column of cells is added to the top or the left, the UIScrollView's contentOffset shifts by the newly added pixels to hide the change in content position.
