以下代码有什么问题?在这里我使用两个表视图并为它们分配不同的数据源,但它不起作用
-(void)viewDidLoad
{
[super viewDidLoad];
arryData = [[NSArray alloc] initWithObjects:@"MCA",@"MBA",@"BTech",@"MTech",nil];
arryData2 = [[NSArray alloc] initWithObjects:@"Objective C",@"C++",@"C#",@".net",nil];
flag=1;
myTable1.hidden=YES;
myTable2.hidden=YES;
btnOne.layer.cornerRadius=8;
btnTwo.layer.cornerRadius=8;
myTable1.layer.cornerRadius=8;
myTable2.layer.cornerRadius=8;
myTable1.delegate=self;
myTable1.dataSource=self;
myTable2.delegate=self;
myTable2.dataSource=self;
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(self.myTable1=tableView)
{
return [arryData count];
}
else {
return [arryData2 count];
}
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 20;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(tableView==self.myTable1)
{
static NSString *CellIdentifier1 = @"Cell1";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1] ;
}
cell.textLabel.text = [arryData objectAtIndex:indexPath.row];
NSLog(@"1here is%i %@",indexPath.row,cell.textLabel.text);
return cell;
}
else
{
static NSString *CellIdentifier2 = @"Cell2";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier2] ;
}
cell.textLabel.text = [arryData2 objectAtIndex:indexPath.row];
return cell;
}
}
-(IBAction)btnCategory:(id)sender
{
if (flag==1) {
flag=0;
myTable1.hidden=NO;
myTable2.hidden=YES;
}
else{
flag=1;
myTable1.hidden=YES;
myTable2.hidden=YES;
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
myTable1.hidden=YES;
myTable2.hidden=YES;
}
-(IBAction)btnTopic:(id)sender
{
if (flag==1) {
flag=0;
myTable2.hidden=NO;
myTable1.hidden=YES;
}
else{
flag=1;
myTable2.hidden=YES;
myTable1.hidden=YES;
}
}

当我删除 mytable2 的数据源时,所有数据都会添加到 table1 中,否则不会在任何表中加载任何数据。
