Question

I am new to iPhone Development. I am trying to push a new table view at didSelectRowAtIndexPath of previous table.

我不明白应该使用什么逻辑。

这是我的代码。

- (void)viewDidLoad {
[super viewDidLoad];

dentalDoc = [[NSMutableArray alloc]initWithObjects:@"one ",@"two",@"Three", nil];
dentalDocImage = [[NSMutableArray alloc]initWithObjects:@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",nil];

searchDocList = [[NSMutableArray alloc]initWithObjects:@"Mary D'souza",@"Eric Josephson",@"Robert Adler",@"Lee Gold",@"Kevin Hansen",@"Karen Ziselman",@"Brad Gosky",@"Mark kogan",@"John Kong",@"Justin kohen",@"Oren Rehmanan",@"Paul Baker",@"Devashish Agarwal",@"Allen Chamberlin",@"Todd Lasner",@"Ryan walsh",@"steven Loan",@"Shrikant Mehta",@"Alexander lobo",nil];

doctorProfileImageList = [[NSMutableArray alloc]initWithObjects:@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",nil];}

和其他表视图方法。

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

// Return the number of sections.
return 1;}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
if (docsInt==0)
{
    return [dentalDoc count];
}
else
{
return [searchDocList count];
}}

以及cellForRowAtIndexPath方法。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

NSString *cellIdentifier  = @"cell";
SearchCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];

if(docsInt == 0)
{
    cell.lblDocName.text = [dentalDoc objectAtIndex:indexPath.row];
    cell.imgProfile.image = [UIImage imageNamed:[dentalDocImage objectAtIndex:indexPath.row]];

}
else
{
cell.lblDocName.text = [searchDocList objectAtIndex:indexPath.row];
cell.imgProfile.image = [UIImage imageNamed:[doctorProfileImageList objectAtIndex: indexPath.row]];

}
return cell;}

我正在尝试检索医生名单，例如Dentist，MBBS，BHMS。选择类别后，我想检索按类别选择的医生姓名列表。

请尽快回复。

如果您使用的是故事板，请使用以下代码

DetailViewController* detailViewController =
[self.storyboard instantiateViewControllerWithIdentifier:@"DetailViewControllerID"];

if([self.navigationController respondsToSelector:@selector(showViewController:sender:)])
    [self.navigationController showViewController:detailViewController sender:self];
else
    [self.navigationController pushViewController:detailViewController animated:animated];

您也可以参考：uitableView didSelectRowAtIndexPath "selected row not loading the detail view"

希望这很有用

我找到了解决方法。这是我的代码。

我有收集视图。其中包含以下Arrays视图中的menuViewController的加载方法。

searchIcons = [NSArray arrayWithObjects:@"empty-filter-xl",@"icon_place",@"ProfilePicRound",@"green_heart_rate",@"MYP",@"Maps-icon", nil];
searchNames = [NSArray arrayWithObjects:@"Dentist",@"MBBS",@"Psychiatrist",@"Cardiologist",@"Nurologist",@"Orthopedic",nil];

这些是集合视图方法。

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section{
return searchIcons.count;
}

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{
static NSString *identifier = @"Cell";
FilterCollectionCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
cell.imgFilterIcon.image = [UIImage imageNamed:[searchIcons objectAtIndex:indexPath.row]];
cell.lblFilterCategory.text = [NSString stringWithFormat:@"%@",[searchNames objectAtIndex:indexPath.row]];

return cell;
}

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath{

SearchList *svc = [self.storyboard instantiateViewControllerWithIdentifier:@"storyBoardIdentifier"];
[self.navigationController pushViewController:svc animated:YES];

if ([[searchNames objectAtIndex:indexPath.row]isEqualToString:@"Dentist"])
{
    svc.docsInt = 0;

}
else if([[searchNames objectAtIndex:indexPath.row]isEqualToString:@"MBBS"])
{
    svc.docsInt = 1;
}
else if([[searchNames objectAtIndex:indexPath.row]isEqualToString:@"Psychiatrist"])
{
    svc.docsInt = 2;
}
else
{
    svc.docsInt = 3;
}
}

在didSelectItemAtIndexPath中，用户将推送到SearchList View Controller，该控制器显示用户选择医生类别的表格视图。

这是searchList视图控制器的代码。

根据医生的类别列出数组。在视图中执行加载方法。

 dentalDoc = [[NSMutableArray alloc]initWithObjects:@"one ",@"two",@"Three", nil];
dentalDocImage = [[NSMutableArray alloc]initWithObjects:@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",nil];

mbbsDoc = [[NSMutableArray alloc]initWithObjects:@"MBBS 1",@"MBBS 2",@"MBBS 3",@"MBBS 4",@"MBBS 5",@"MBBS 6",@"MBBS 7", nil];
mbbsDocImage = [[NSMutableArray alloc]initWithObjects:@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon", nil];

PsychiatristDoc = [[NSMutableArray alloc]initWithObjects:@"Doctor 1",@"Doctroe 2",@"Doctor 3",@"Doctor 4",@"Doctor 5", nil];
PsychiatristDocImage = [[NSMutableArray alloc]initWithObjects:@"empty-filter-xl",@"icon_place",@"ProfilePicRound",@"green_heart_rate",@"MYP",nil];

searchDocList = [[NSMutableArray alloc]initWithObjects:@"Mary D'souza",@"Eric Josephson",@"Robert Adler",@"Lee Gold",@"Kevin Hansen",@"Karen Ziselman",@"Brad Gosky",@"Mark kogan",@"John Kong",@"Justin kohen",@"Oren Rehmanan",@"Paul Baker",@"Devashish Agarwal",@"Allen Chamberlin",@"Todd Lasner",@"Ryan walsh",@"steven Loan",@"Shrikant Mehta",@"Alexander lobo",nil];
doctorProfileImageList = [[NSMutableArray alloc]initWithObjects:@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",@"ProfilePicRound",@"MapiCon",nil];

这是表视图方法。

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
if (docsInt==0)
{
    return [dentalDoc count];
}
if (docsInt==1)
{
    return [mbbsDoc count];
}


 if (docsInt == 2){
   return [PsychiatristDoc count];}
else
{
    (docsInt == 3);
    return [searchDocList count];
}}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

NSString *cellIdentifier  = @"cell";
SearchCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];

if(docsInt == 0)
{
    cell.lblDocName.text = [dentalDoc objectAtIndex:indexPath.row];
    cell.imgProfile.image = [UIImage imageNamed:[dentalDocImage objectAtIndex:indexPath.row]];
}
else if (docsInt == 1)
{
    cell.lblDocName.text = [mbbsDoc objectAtIndex:indexPath.row];
    cell.imgProfile.image = [UIImage imageNamed:[mbbsDocImage objectAtIndex:indexPath.row]];
}
else if(docsInt == 2)
{
    cell.lblDocName.text = [PsychiatristDoc objectAtIndex:indexPath.row];
    cell.imgProfile.image = [UIImage imageNamed:[PsychiatristDocImage objectAtIndex:indexPath.row]];
}
else
{

    cell.lblDocName.text = [searchDocList objectAtIndex:indexPath.row];
    cell.imgProfile.image = [UIImage imageNamed:[doctorProfileImageList objectAtIndex: indexPath.row]];
}
    return cell;}

最后但并非最不重要的导航方法。

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
// Get the new view controller using [segue destinationViewController].
// Pass the selected object to the new view controller.

if ([segue.identifier isEqualToString:@"Detail"])
{
    NSIndexPath *indexpath = [tblList indexPathForSelectedRow];
    DoctorProfile *destViewController = segue.destinationViewController;
    //destViewController.doctorName = [

    if (docsInt == 0)
    {
        destViewController.doctorName = [dentalDoc objectAtIndex:indexpath.row];
    }
    if (docsInt == 1)
    {
        destViewController.doctorName = [mbbsDoc objectAtIndex:indexpath.row];
    }
    if (docsInt == 2)
    {
        destViewController.doctorName = [PsychiatristDoc objectAtIndex:indexpath.row];
    }
    else
    {
        destViewController.doctorName = [searchDocList objectAtIndex:indexpath.row];
    }


}}

谢谢。

如何在didselectrowatindexpath推送新的表格视图？
