I'm beginner with collection view,
I need to create cell like this
Can I do it from Storyboard?
I want to add margin of cell = 4 or 5 in the top, bottom, lift and right in iPhones and iPads of all sizes, or I if need to do that programmatically How I can add the contents of the cell like the image above?
There is no "margin" here. There is simply a rectangle with a shadow, and everything else is drawn in front of it. The simplest solution is probably a custom UIView that draws itself as a rectangle with a shadow. Make that the content view's direct subview, and everything else in the cell is a subview of that. The inset of the rectangle-with-shadow within the cell's content view can be determined by autolayout (and the position of all the stuff inside it can be determined by autolayout too).
Thus it was trivial for me to obtain this sort of thing:
And of course you can tweak the border color, the background color, and so forth.

I am creating an iPad view which has a tableview as a subview. The tableview only takes a small portion of the screen and is somewhere near the middle of the screen and it contains some menu items. I want people to be about to scroll this tableview up and down however I do not like how the cells disappear against a hard edge. When I set clipsToBounds to false, I get what I want in that the hard edge is not there anymore but the top/bottom cell disappears when the tableview needs that cell for recycling. Is there a common technique to avoid this hard-edge of when the cells scroll up against the tableview's bounds? I was thinking of adding gradient alpha masks on a parent container view but it seems a bit over the top.
There are no hard and fast rule about this, but you certainly can do whatever you feel best. What I would do in a case of floating tableView is giving it a nice border using layer. It is easy to code (2~3 lines). Round the edge to make it pretty.
If you want to drop shadow, it gets a little more complicated but possible. Just draw a bezier curve path of a rectangle (where you want your shadow to appear). Assign that CALayer shadowPath. Then add it to the table.
You can also gradient an alpha to make it appear shadow like.
But I would suggest, you set clipsToBounds to YES since it looks horrible otherwise, given the fact that the table 'floats' somewhere in your view.
I am working on an app that has TableViewCells with varying heights. I am placing a UIImageView into them and each will use the same size image (the same size of the largest cell), however I need to mask the excess in the smaller cells (keeping the bottom, not the top).
To be more specific, I have 3 different cell heights, 112, 104 and 88. The images will all be 112 tall and I want the images to have the tops cut off on the smaller cells. Im pretty sure the answer lies within the bounds, frame and center attributes of a UIImageView, but I cant figure out exactly what I should be doing.
You will need to set the frame of your image view such that the bottom of the image view is aligned with the bottom of your cell.
You will also need to ensure the contentview of you cell is clipping content to its bounds (setClipToBounds to yes).
If I had to do this I would subclass the UITabelViewCell class and implement the layoutSubviews method. In your implementation don't forget to call super first so the content view has the right size (also if you go in editing mode). Then use the content view bounds and place your content accordingly.
When you add the image view to the cell, it should automatically cut off the top part, as long as you have the UIImageView bottom positioned within the frame, it should be what you wanted.
The design of the UITableView is something like this:
I want to make my cells with a tiny triangle, like in a comic book. The thing is, how can i add the triangle to the size of my custom cell? The common rectangle size wouldn't work if i want the user to be able to tap that little rectangle.
And how can i make the opposite? I want the triangle to cover the space of another cell, so tapping the little triangle of the first cell, covering part of the second cell's rectangle space, would activate de first one. This is, substracting a little triangle from the cell's space.
Not sure it would work, but building on user697562's comment, you could try the following:
Add a small UIView to the table cell to represent the small triangle
Rotate it using its transform property, making sure that, along with its frame, it will have the proper placement.
Add a UITapGestureRecognizer to the UIView
Add an instance variable to the view to save the indexPath of the cell it's in (or even the above cell, since it will be associated with the above cell). This way when the gesture recognizer is triggered, you know what row you're in.
Write the action method associated with the gesture recognizer to do the same thing as tableView:didSelectRowAtIndexPath: would do for the above cell.
Set the separatorStyle property of the UITableView to UISeparatorStyleNone, so that it won't draw the lines between cells. If this doesn't work just set the separatorColor property to your table cell's background color.
Draw a border along the top & bottom of the cell, accounting for the triangle.
Good luck with it! Let me know whether it works if you try it.
What's the UI element that is top of that number buttons to display number ? (which is in light blue color)
It looks like a UINavigationBar with a prompt. However, the location of the gloss (which differs from your typical UINavigationBar) and the centering of the numbers (not shown) makes me think it is a custom view.
If you're trying to replicate it, I'd suggest starting with a UIView. Add a UIImageView with appropriate image for the the blue background and a UILabel for the text. Or, instead of the UIImageView, you could draw the background in the UIView's drawRect: method.
I am currently working on an application for a client, and they have made an odd request. The request involves putting a custom image as the indicator for the scrollview. I am not even sure if this is possible but if it is can you please let me know how one would go about doing that.
Thanks
UIScrollView streches a small, semi-transparent circle image to generate its scrollbars. You can find this image as the first subview of a UIScrollView:
UIImageView *circle = [scrollView.subviews objectAtIndex:0];
However, as I said this image is stretched, and as far as I can tell, only the alpha values are considered when drawing the scroll bars.
So for example if you're only interested in changing the top/bottom ends of the scroll bar, you can try to change this image. However, I doubt you'll be able to do anything interesting.
A possible solution that comes to mind, and this is only a theory, is to add a custom, transparent UIView on top of a UIScrollView. Then you can hide the default scroll bar (by using showsHorizontalScrollIndicator and showsVerticalScrollIndicator), pass the necessary touch events to the UIScrollView to scroll the content, and draw the scrollbars in your custom view.
