Objective-C iPhone Programming Lesson 15 - Scores and Randomizations

I show you how to make a score indicator. We also add randomization to the buttons position each time you click it.

I think that it's a little more clear to typecast the buttonframe.size.blah into the unsigned type. It's really personal preference and I don't think in this case or any case it really matters. String typecasts are the only thing that really matter. Also I would suggest flipping the velocities on every click as well. =P. I'm more familiar with the c++ and c# side and have programmed a few things for the WP7, but your tutorials inspire me to do obj-c in my spare time. doing mult obj&app&disapp =D

@malakov5 Alright, so it so happens that the status bar is exactly 20 pixels tall, meaning that the frame is actually 460 pixels heigh. You can get this by doing self.view.frame.size.height.

so in my video response I talked about the useable window dimensions. your 320x480 dimension will work just fine if you enable statusbar hiding while in the game view. in the plist, add a new row and add: status bar is originally hidden: and check the box. voila, the bar is hidden.

@imopsvideo I am currently having the same-ish problem. When I download Xcode from the apple developer website, it downloads, but it is corrupt. I talked to someone else who also was trying to download Xcode, and he is having the same problem.

@JailPodiOS5 Try changing it to abs(arc4random() % 320)

Hi machead101 I followed your tutorial and executed but when the score is getting updated the button goes back and starts moving from the initial location from where it starts Then I tried by commenting the setText line of UILabel then the buttons works fine as expected. On click of button it continuous to move
