Save the position (CGPoints) of a image.

[BarryK88]

I'm trying to save the positions of several images whom are inside my view. How can i store the coordinates of the images so that when the App launches the images are still at the same location?

Thanks in advance!

How many images locations are you trying to save?

If not many, you can use NSUserDefaults to save each individual point. You'll want to first convert the point to an NSString using NSStringFromCGPoint( thePoint ). And later, when you read the string from NSUserDefaults, there is a corresponding method to convert a string back to a CGPoint.

If you are saving a lot of points, it will probably be easier to do what is described above, but add each of the strings to an NSArray and then save the array to NSUserDefaults.

I got 20 images in total. Still got no clue about the next thinking steps.

Help is greatly appreciated!

Are we talking about ImageViews or UIImages, because the latter don't have position, they're just images. If you have image views then you can save the value pairs of .frame.origin.x and .frame.origin.y, then reload on launch and restore the position.

We are talking about 20 UIImageViews. I placed them within my viewDidLoad method like:

image1.center = CGPointMake(381, 637);
etc.

A user is able to drag is UIImageView by means of the touchesmethod, so the coordinates change after dragging. I'd like to save those new coordinates of the UIImageViews.

Any suggestions?

you can use NSDictionary or NSArray to collect your coordinates and then NSUserDefault to store that dictionary/array and retrieve it.

ps: you need to use NSNumber (or NSValue) to save your coordinates (that are primitives) to an dictionary/array (that is an object).

Any luck with this?
