[英]How to set different countdown timer to different labels of collectionviewcell in ios?
I am working on an application where I have to get seconds left in event (Which is different for all the events) and then I have to print the countdown time (ie time left) for event in each collectionviewcell.Number of rows here are 5 for suppose. 我正在一个应用程序上工作,我必须在事件中还剩几秒钟(所有事件都有所不同),然后我必须在每个collectionviewcell中打印事件的倒数时间(即剩余时间)。这里的行数是5假设吧。
- (col *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
static NSString *identifier = @"Cell";col *cell = [collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
secondsLeft= seconds left depending on data which I can get successfully;
[self start];
cell.lbl_time.text=[NSString stringWithFormat:@"%02d:%02d:%02d", hours, minutes, seconds];
return cell;} -(void)updateCounter:(NSTimer *)theTimer{
if(secondsLeft > 0 ) {
secondsLeft -- ;
hours = secondsLeft / 3600;
minutes = (secondsLeft % 3600) / 60;
seconds = (secondsLeft %3600) % 60;
//count.text = [NSString stringWithFormat:@"%02d:%02d:%02d", hours, minutes, seconds];
}
else
{
NSLog(@"Timer Invalidate");
// [timer invalidate];
}} -(void)start{
timer=[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(updateCounter:) userInfo:nil repeats:YES];}
Let me know what I should do. 让我知道我该怎么办。 Thanks in advance. 提前致谢。
