Need Help With NSTimer and UISegmentedControl
I have the following code that works for a Timer view.
The problem is, when I change segments, while the timer is already running, the label resets, but the button text still stay's stop, I need it to stay "start" instead. I tried doing it manually by doing self.timer.titleLabel.text = @"Start";
but for some reason it shows as "S...t"
instead of "Start"
.
- (IBAction)startStop:(UIButton *)sender
{
if ( self.myTimer )
{
[self.myTimer invalidate];
self.myTimer = nil;
[sender setTitle:@"Start" forState:UIControlStateNormal];
}
else
{
self.myTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(handleTimer:) userInfo:nil repeats:YES];
[sender setTitle:@"Stop" forState:UIControlStateNormal];
}
}
- (void)handleTimer:(NSTimer *)timer
{
self.counter--;
self.timerLabel.text = [NSString stringWithFormat:@"%ld", self.counter];
if ( self.counter <= 0 ){
[self.myTimer invalidate];
self.myTimer = nil;
}
}
- (IBAction)reset:(id)sender
{
self.counter = self.counterSegment;
self.timerLabel.text = timerCount;
}
- (void)segmentedControl:(SVSegmentedControl*)segmentedControl didSelectIndex:(NSUInteger)index
{
if ( self.myTimer )
{
[self.myTimer invalidate];
self.myTimer = nil;
self.timer.titleLabel.text = @"Start";
}
if (index == 0)
{
NSLog(@"15 sec");
self.timerCount = @"15";
self.counterSegment = 15;
}
else if (index == 1)
{
NSLog(@"30 sec");
self.timerCount = @"30";

}
else if (index == 2)
{
NSLog(@"60 sec");
self.timerCount = @"60";
self.counterSegment = 60;
}
self.counter = self.counterSegment;
self.timerLabel.text = timerCount;
}
If the button label reads "S...t" instead of "Start", then you need to make the font smaller or invoke adjustsFontSizeToFitWidth
, e.g.
button.titleLabel.font = [UIFont systemFontOfSize: 10];
or
button.titleLabel.adjustsFontSizeToFitWidth = YES;
