如何在选择中突出显示自定义UIButton约5秒，然后重定向到其他视图？在我的代码中，选择时不会显示任何颜色而是重定向到其他视图。

这是我的代码：

-(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];
}

我该怎么做？

Answer 1

您必须将setShowsTouchWhenHighlighted:yes设置为UIButton。

例如：

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

你只需在该方法中添加sleep（5）;

例如：

这是用户示例uibutton操作方法。

- （无效）样品{

睡眠（5）;

sampleclass * classobject = [[sampleclass alloc] init]; [self.navigationController pushViewController：classobject animated：YES];

}

Answer 3

我不建议使用sleep（），因为这会睡眠所有线程并使应用程序基本上死了x秒。

按照上述说明突出显示按钮，然后使用

[self performSelector:@selector(sample) withObject:self afterDelay:5.0f];


-(void)sample
{
     UIViewController *myNewController = [[UIViewController alloc]init];
    enter code here
    [self presentModalViewController:myNewController animated:YES];
}

在iPhone中保留UIButton的一小部分时间？
