uilabel 添加点击事件
UITapGestureRecognizer *tapGestureTel = [[[UITapGestureRecognizeralloc]initWithTarget:self action:@selector(teleButtonEvent:)]autorelease];
[telephoneLabel addGestureRecognizer:tapGestureTel];
collectionView
/*------------类目详细列表----------*/ UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init]; // flowLayout.itemSize = CGSizeMake(63, 75); //三列的 flowLayout.itemSize = CGSizeMake(100, 120); flowLayout.scrollDirection = UICollectionViewScrollDirectionVertical; //滚动方向的设置--垂直 // flowLayout.scrollDirection = UICollectionViewScrollDirectionHorizontal; //滚动方向 --水平 flowLayout.minimumLineSpacing = 10; self.collectionView = [[UICollectionView alloc] initWithFrame:CGRectMake(95, 108, 215, 426) collectionViewLayout:flowLayout]; self.collectionView.backgroundColor = [UIColor whiteColor]; self.collectionView.delegate = self; self.collectionView.dataSource = self; // self.collectionView.showsHorizontalScrollIndicator = NO; //隐藏水平滚动条 self.collectionView.showsVerticalScrollIndicator = NO; //隐藏垂直滚动条 [self.collectionView registerClass:[MyUICollectionViewCell class] forCellWithReuseIdentifier:@"aaa"]; [self.view addSubview:self.collectionView]; [flowLayout release]; [_collectionView release];
NSNumber * time= listModel.lastUptrackAt; NSDate *date = [[[NSDate alloc]initWithTimeIntervalSince1970:[time doubleValue]/1000.0]autorelease]; //把毫秒的时间转化成时间 NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; dateFormatter.dateFormat = @"yyyy-MM-dd"; NSString *date2 = [dateFormatter stringFromDate:date]; //把时间进行格式化 cell.labelTime.text = [NSString stringWithFormat:@"最后更新:%@",date2];
ios设置tableview默认选中第一行并实现点击第一行的效果
//如果有数据,默认选中第一行并请求第一行的数据 if(self.tableViewData.count>0) { [self.tableView selectRowAtIndexPath:[NSIndexPath indexPathForItem:0 inSection:0] animated:YES scrollPosition:UITableViewScrollPositionTop];//设置选中第一行(默认有蓝色背景) [self tableView:self.tableView didSelectRowAtIndexPath:[NSIndexPath indexPathForItem:0 inSection:0]];//实现点击第一行所调用的方法 }
