我面临一个问题,没有调用 didselectrowatindexpath。我的tableview在viewdidload中设置如下:
- (void)viewDidLoad
{
//[super viewDidLoad];
self.tableView.delegate = self;
self.tableView.dataSource = self;
[self.tableView reloadData];
self.detailViewController = (klViewController *)[[self.splitViewController.viewControllers lastObject] topViewController];
}
现在我的 cellForRowAtIndexPath 被调用,我正在重用单元格,如下所示:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"menuSelection1";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
AmbassadorInfoData * data = [self.LoadMenuItems objectAtIndex:indexPath.row];
cell.textLabel.text = data.treeName;
return cell;
}
我已经检查了其他答案,并且大多说可能会使用 didDeselectRowAtIndexPath 。但这里不是这种情况。现在我的问题出在我的拆分视图控制器中,每当我选择任何选项时,相应的详细视图都不会显示并且是空白的。我在 rootview 控制器(klViewController)中的方法都没有被调用。这可能是什么原因?以下是与 UITableView 相关的所有方法。它在与 viewDidLoad 相同的类中实现
#pragma mark - Table view data source
- (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.
return [self.LoadMenuItems count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"menuSelection1";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
AmbassadorInfoData * data = [self.LoadMenuItems objectAtIndex:indexPath.row];
cell.textLabel.text = data.treeName;
return cell;
}
-(NSArray *)LoadMenuItems
{
NSMutableArray * menuData = [[NSMutableArray alloc] initWithCapacity:5];
AmbassadorInfoData * data = [[AmbassadorInfoData alloc] init];
data.treeName = @"Ambassador Info";
data.treeDescription = @"This is temp data.";
NSString * file = [[NSBundle mainBundle] pathForResource:@"oak" ofType:@"jpg"];
data.treePhoto = [UIImage imageWithContentsOfFile:file];
[menuData addObject:data];
data=nil;
data = [[AmbassadorInfoData alloc] init];
data.treeName = @"AmbassadorInternalList";
data.treeDescription = @"This is temp data.).";
file = [[NSBundle mainBundle] pathForResource:@"DouglasFir" ofType:@"jpg"];
data.treePhoto = [UIImage imageWithContentsOfFile:file];
[menuData addObject:data];
data=nil;
data = [[AmbassadorInfoData alloc] init];
data.treeName = @"Text 3";
data.treeDescription = @"This is temp data.";
file = [[NSBundle mainBundle] pathForResource:@"SugarMaple" ofType:@"jpg"];
data.treePhoto = [UIImage imageWithContentsOfFile:file];
[menuData addObject:data];
data=nil;
data = [[AmbassadorInfoData alloc] init];
data.treeName = @"Text 4";
data.treeDescription = @"This is temp data.";
file = [[NSBundle mainBundle] pathForResource:@"RedMaple" ofType:@"jpg"];
data.treePhoto = [UIImage imageWithContentsOfFile:file];
[menuData addObject:data];
data=nil;
data = [[AmbassadorInfoData alloc] init];
data.treeName = @"Text 5";
data.treeDescription = @"This is temp data.";
file = [[NSBundle mainBundle] pathForResource:@"Pine" ofType:@"jpg"];
data.treePhoto = [UIImage imageWithContentsOfFile:file];
[menuData addObject:data];
menuItems = [[NSArray alloc] initWithArray:(NSArray *)menuData];
data=nil;
return menuItems;
}
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
AmbassadorInfoData * selectedItem =(AmbassadorInfoData *)[self.menuItems objectAtIndex:[self.tableView indexPathForSelectedRow].row];
detailObject = selectedItem;
[detailViewController setDetailItem:detailObject];
}
