Objective-c Method to get a number then countdown in 1 every second
- by Sami
Hi, i need a little help i have a method which gets value such as 50, it then assigns that value to trackDuration, so NSNumber *trackDuration = 50, i want the method to every second minus 1 from the value of trackDuration and update a label, the label being called duration.
Here's what i have so far;
- (void) countDown {
iTunesApplication *iTunes = [SBApplication applicationWithBundleIdentifier:@"com.apple.iTunes"];
NSNumber *trackDuration = [NSNumber numberWithDouble:[[iTunes currentTrack] duration]];
while (trackDuration > 0) {
trackDuration - 1;
int inputSeconds = [trackDuration intValue];
int hours = inputSeconds / 3600;
int minutes = ( inputSeconds - hours * 3600 ) / 60;
int seconds = inputSeconds - hours * 3600 - minutes * 60;
NSString *trackDurationString = [NSString stringWithFormat:@"%.2d:%.2d:%.2d", hours, minutes, seconds];
[duration setStringValue:trackDurationString];
sleep(1);
}}
Any help would be much appreciated, thanks in advanced, Sami.
