The age-old problem. Files, that are stored with padded zeros 000, 001, 002, 003 – and a counter that doesn’t have this zero-padding. There are probably myriad solution to that problem, here’s my take:

Create a temporary string consisting of a minimum of 3 characters length.

NSString *tempZeros = [NSString stringWithFormat:@"00%i", i];

Get the last 3 characters, shave off the rest.

NSString *zeroPaddedIndex = [tempZeros substringFromIndex:[tempZeros length] - 3];

No if’s, no but’s, no clauses.

Update: Of course, there’s always a better way. 452

As seen in iPhone SDK 3.2 beta 2 and the “A signed resource has been added, modified, or deleted.” error message.

Solution? Switch back to iPhone SDK 3.1.3 with XCode 3.2.1

Apparently several different versions of XCode (and the Developer Folder) can happily coexist. Just rename one DeveloperBeta or something like that…

float f = 1.23456;
 
NSLog(@"%.2f", f);
NSLog(@"%.0f", f);
NSLog(@"%.0f", f);

[NSTimer scheduledTimerWithTimeInterval:1.0

Alternative to Part I [35], has the possibility of repetetive calls.

Not sure if anyone except me will need this information again.

Situation: A legacy RubyCocoa Application that runs fine in OSX 10.5, but refuses to compile in 10.6. RubyCocoa is working, only access to constants seems to be problematic.

So far the following workarounds:
