This is a simple timer, you may need to declare some variables in the .h file.
-(void)onViewDidLoad {
//set on start up
NSDate *startTime = [NSDate date];
}
-(void)someOtherFunction {
//amount to dely by (seconds)
NSInteger *delayAmount = 1;
//work out the current delay time
NSTimeInterval elapsedTime = [startTime timeIntervalSinceNow];
//if the delay is bigger than the specified amount then...
if (elapsedTime >= delayAmount) {
//Do the stuff to do when the delay time has passed
NSDate *startTime = [NSDate date];
}
To round a number use the following code:
CGFloat variable = ...CGFloat result = round(variable * 1000.0) / 1000.0;
or
CGFloat variable = round(variable * 1000.0) / 1000.0;[/code]
Use 1000 for 3decimal places, 100 for 2 etc!
My new look portfolio is now up and running. I am still uploading some of my older designs so if I am missing one of your favorites check back soon to see it, or let me know what and I will do what I can about getting it online for you.Please have a look around and see if there is anything that catches your eye. Who knows, maybe I can do something for you? Let me know what you think.
Thanks

The tags in question are META tags. They are the bits of code that sit in between the <HEAD> </HEAD> tags and tell search engines whats in a page (except google which actually reads a pages text content).
Meta data should be put just after the <TITLE> tags in the <HEAD>. It tales the format <META name="the catagory" content="the information">. The name is usually one of 4 types - "description", "resource-type", "keywords" or "distribution". The information depends on the name. I will briefly cover the two that are most important for a search engine: "description" and "keywords". The "keywords" are a list of main topics covered by the page in question. This blog has the keywords "photoshop, illustrator, dreamweaver, Hints, Tips, Techniques, Carl Topham" since thats the main list that covers it. Separate each keyword with a comma (and space). Keywords can be two words so "Carl Topham" is counted as one keyword. Try to keep the keywords restricted to less than about 250 characters as some search engines actually reduce page ranking if you use too many. The "description" is just that. It's a more people friendly description of your page. Try to sumarise in 2-3 sentences. Some search engines use it but its usually just the bit shown under your link in the search engine. You should end up with code that looks like:
<META NAME="Keywords" CONTENT="illustration, Carl Topham, photoshop, illustrator, dreamweaver, Hints, Tips, Techniques"> <META NAME="Description" CONTENT="The official blog of Carl Topham. Containing a range of graphic design, web design....">
Save and upload to your server. If you are using wordpress the you need to login and goto "presentation > theme editor" and choose "header" on the page list on the right. Then paste it on a new line after the <TITLE ...

Why? For any design the environment is usually a second priority to cost. Businesses run to make money so that is where the focus is aimed. So why would a business want to shift more focus onto the environment. What I am briefly going to cover are a few very good reasons for cost and not for the classic argument to save the world for my children and my children's children.
How? What methods are best for saving a bit of cash when designing / producing a product? There are many many ways to reduce cost and help protect the environment. Most just require a bit of extra thinking when designing. Here are a few ways I have found to get you started: When designing products, money can be saved in the long run by carefully designing products to use materials and resources efficiently. This reduces waste during the initial building stage and also at the end of the product life cycle.
Using already recycled materials or using materials that can easily be recycled. Design packaging that can be easily separated into key materials that can be recycled. This reduces disposal costs which are sometimes charged to the original manufacturer. Using simple fastening methods instead of adhesives is often a good way to do this.
Do not over use packaging. Some products do not need a huge box with many layers of wrapping and padding. Not only will you reduce costs in material but transport costs can be reduced due to smaller space usage.
Take ideas from nature. Nature has been designing for quite a bit longer than anyone around and has got the efficient use of materials down to a fine art. Its not just amounts of material used, it's also the ways they are used. Shapes and ...
