Keep a UIButton selected for a fraction of time in iPhone? - iphone

Question

How can I keep a custom UIButton highlighted on selection, for about 5 seconds and then redirect to other view? In my code it is not showing any color when selected rather redirecting to other view.
This is my code :
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
CGRect rect=CGRectMake(0+70*j,yy,79,40);
UIButton *button=[[UIButton alloc] initWithFrame:rect];
[button setFrame:rect];
[button setContentMode:UIViewContentModeLeft];
button.titleLabel.font = [UIFont systemFontOfSize:14];
NSString *settitle=[NSString stringWithFormat:#"%#",item.TimeStart];
[button setTitle:settitle forState:UIControlStateNormal];
NSString *tagValue=[NSString stringWithFormat:#"%d%d",indexPath.section+1,i];
button.tag=[tagValue intValue];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button setShowsTouchWhenHighlighted:YES];
[button addTarget:self action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside ];
[hlcell.contentView addSubview:button];
[button release];
}
-(IBAction)buttonPressed:(id)sender
{
[sender setBackgroundColor:[UIColor cyanColor]];
Login *lgn=[[Login alloc] init];
[self presentModalViewController:lgn animated:NO];
[lgn release];
}
How can I do it ?

Answer 1

You have to set setShowsTouchWhenHighlighted:yes to the UIButton.
for example:
UIButton *click_btn=[UIButton buttonWithType:UIButtonTypeCustom];
click_btn.frame=CGRectMake(238,10, 70, 70);
[click_btn setTag:indexPath.row];
[click_btn setShowsTouchWhenHighlighted:YES];
[click_btn addTarget:self action:#selector(sample) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:click_btn];

Answer 2

you just add inside that method sleep(5);
for example:
This is user sample uibutton action method.
-(void)sample{
sleep(5);
sampleclass *classobject=[[sampleclass alloc]init];
[self.navigationController pushViewController:classobject animated:YES];
}

Answer 3

I wouldn't suggest using sleep() as this sleeps all threads and makes the app essentially dead for x seconds.
Highlight the button as per the instructions above and then use
[self performSelector:#selector(sample) withObject:self afterDelay:5.0f];
-(void)sample
{
UIViewController *myNewController = [[UIViewController alloc]init];
enter code here
[self presentModalViewController:myNewController animated:YES];
}
