先上图：
我们经常在项目中使用到UISegmentControl进行UITableView的切换 下面我说说我实现的过程。
这个UISegmentControl我是放在导航栏的中间的，实现代码如下：
//创建导航栏分栏控件
-(void)createSegMentController{
NSArray *segmentedArray = [NSArray arrayWithObjects:@"问答",@"倾述",nil];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc]initWithItems:segmentedArray];
segmentedControl.frame = CGRectMake(0, 0, 180, 30);
segmentedControl.selectedSegmentIndex = 0;
segmentedControl.tintColor = [UIColor colorWithRed:252/255.0 green:245/255.0 blue:248/255.0 alpha:1];
[segmentedControl addTarget:self action:@selector(indexDidChangeForSegmentedControl:) forControlEvents:UIControlEventValueChanged];
[self.navigationItem setTitleView:segmentedControl];
}
下面讲讲如何实现UITableView的切换：
创建两个UITableView
UITableView *leftTable;
UITableView *rightTable;
leftTable = [[UITableView alloc]initWithFrame:CGRectMake(0,64,WIDTH,HEIGHT-64-44) style:UITableViewStylePlain];
leftTable.delegate = self;
leftTable.dataSource = self;
[leftTable registerNib:[UINib nibWithNibName:@"AnswerCell" bundle:[NSBundle mainBundle]] forCellReuseIdentifier:AnswerReuseId];
leftTable.separatorStyle = UITableViewCellSeparatorStyleNone;
[self.view addSubview:leftTable];
rightTable = [[UITableView alloc]initWithFrame:CGRectMake(0,64,WIDTH,HEIGHT-64-44) style:UITableViewStylePlain];
rightTable.delegate = self;
rightTable.dataSource = self;
[rightTable registerNib:[UINib nibWithNibName:@"AnswerCell" bundle:[NSBundle mainBundle]] forCellReuseIdentifier:AnswerReuseId];
rightTable.separatorStyle = UITableViewCellSeparatorStyleNone;
[self.view addSubview:rightTable];
- 接下来我们实现切换：
-(void)indexDidChangeForSegmentedControl:(UISegmentedControl *)sender
{
//我定义了一个 NSInteger tag，是为了记录我当前选择的是分段控件的左边还是右边。
NSInteger selecIndex = sender.selectedSegmentIndex;
switch(selecIndex){
case 0:
leftTable.hidden = NO;
rightTable.hidden = YES;
sender.selectedSegmentIndex=0;
tag = 0;
[leftTable reloadData];
break;
case 1:
leftTable.hidden = YES;
rightTable.hidden = NO;
sender.selectedSegmentIndex = 1;
tag=1;
[rightTable reloadData];
break;
default:
break;
}
}
接下来实现UITableView的代理和数据源
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
if(tag==0){
return array.count;
}
else if (tag==1){
return array.count;
}
return 0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
if(tag == 0){
AnswerCell *cell = [leftTable dequeueReusableCellWithIdentifier:AnswerReuseId ];
if (!cell) {
cell = (AnswerCell *)[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier: AnswerReuseId];
}
//cell.model = array[indexPath.row];
cell.content.text = array[indexPath.row];
cell.userImg.image = [UIImage imageNamed:@"tabbar_home_selected@2x"];
cell.userName.text = @"一个演员的自我修养";
cell.title.text = @"演员的自我修养";
cell.time.text = @"4小时前";
cell.star.text = @"1344";
cell.counts.text = @"445";
// 获取不确定文字的高度
NSString *str = array[indexPath.row];
CGFloat testHeight = [self sizeWithFont:[UIFont systemFontOfSize:14.0] maxW:cell.frame.size.width withContent:str] + 10;
// 重新设置cell的frame.
CGRect frame = cell.frame;
frame.size.height = testHeight + self.originCellMaxY;
cell.frame = frame;
return cell;
}
else if (tag==1){
AnswerCell *cell = [rightTable dequeueReusableCellWithIdentifier:AnswerReuseId ];
if (!cell) {
cell = (AnswerCell *)[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier: AnswerReuseId];
}
//cell.model = array[indexPath.row];
cell.content.text = array[indexPath.row];
cell.userImg.image = [UIImage imageNamed:@"tabbar_home_selected@2x"];
cell.userName.text = @"一个演员的自我修养";
cell.title.text = @"演员的自我修养";
cell.time.text = @"4小时前";
cell.star.text = @"1344";
cell.counts.text = @"445";
// 获取不确定文字的高度
NSString *str = array[indexPath.row];
CGFloat testHeight = [self sizeWithFont:[UIFont systemFontOfSize:14.0] maxW:cell.frame.size.width withContent:str] + 10;
// 重新设置cell的frame.
CGRect frame = cell.frame;
frame.size.height = testHeight + self.originCellMaxY;
cell.frame = frame;
return cell;
}
return nil;
}
效果图是这样的：
对了说一下，每个单元格之间那段距离 我是在自定义的cell中放了一个高度为10的UIView。哈哈
就是这个样子：
