The 5 lines that set up workingFrame can be replaced by a single line:

CGRect workingFrame = CGRectMake(15, 400, 40, 40);

Although for beginners it might be helpful to show what exact component of the working frame is being set.

same question i hav that of icodeblog…..
Is there a way to animate the squares? For example pass through an array of 6 .pngs to create animations? Maybe change all the blue squares to little spiders with moving legs?

I just add random to UIView squares with arc4random(),
you just add
int xm = (arc4random() % 6)+1;
NSLog(@”My XM number is %d”, xm);

for(int i = 0; i < xm; i++)
{
UIView *myView = [[UIView alloc] initWithFrame:workingFrame];
bla..bla….

Maybe a silly question (noob inside ), but myView are not released ? It should be ?

Hi,

Great stuff!

Just one thing though.
The two lines of code below produce four errors and i am unsure what the < is doing.

for(int i = 0; i < 6; i++)

if(workingFrame.origin.y < 0)

I think they should read:

for(int i = 0; i < 6; i++)

if(workingFrame.origin.y < 0)

Thank You

Alex

Nice tutorial! I prefer use arc4random() instead of rand(). By using rand() you will get the same result every time. Arc4random() is a real random generator
Right?

Nice example. Just not sure about calling them a poor man’s thread though.

The only problem I have with NSTimer’s is that they can be innacurate.

Instead of looping through the views to get to the appropriate tag, why not do the following?:

UIView *aView = [self.view viewWithTag:r];

Also, you might want to start your tags with 1 instead of 0. The default tag value is 0 and, even though it works in this case where you have no other views, it will clash if you add more views that you don’t explicitly tag.

UIGraphicsBeginImageContext(self.view.bounds.size);

[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

you must also #import

Techy: Hold the home button, and press the sleep button.

Or take a screenshot of the simulator.

Very Cool! Do you think that you guys could make a tutorial on how to add screenshots to your app?
