我似乎无法推送到其他UITableView。当我运行代码时,它仅显示EventType,并且在单击时确实将推发送到另一个UITableView,从而显示事件。该代码假定将一个UITableView推送到另一个UITableView。请有人可以帮助我解决我遇到的这个问题。我认为它来自RootViewController,但我似乎无法查明问题所在。
该应用程序正常运行,但是我无法推送到其他TableViewController。这是使用的代码,这里是使用的代码,但是由于大多数设置是使用IB完成的,因此并没有真正揭示出太多内容。
这是RootViewController.m
-我认为问题是由此引起的,但我似乎无法查明从何而来。
#import "RootViewController.h"
#import "EventTypeViewController.h"
@interface RootViewController ()
@end
@implementation RootViewController
@synthesize eventType;
- (void) viewDidLoad
{
eventType = [[NSMutableArray alloc]init];
[eventType addObject:@"Corporate"];
[eventType addObject:@"Social"];
[eventType addObject:@"Dining"];
[self setTitle: @"Events"];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [eventType count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
cell.textLabel.text = [[eventType objectAtIndex:indexPath.row]retain];
[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];
return cell;
}
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
EventTypeViewController *events = [[EventTypeViewController alloc] initWithNibName:@"EventTypeViewController" bundle:nil];
if ([[eventType objectAtIndex:indexPath.row] isEqual:@"Corporate"])
{
events.eventsInt = 0;
[events setTitle:[eventType objectAtIndex:indexPath.row]];
}
if ([[eventType objectAtIndex:indexPath.row] isEqual:@"Social"])
{
events.eventsInt = 1;
[events setTitle:[eventType objectAtIndex:indexPath.row]];
}
if ([[eventType objectAtIndex:indexPath.row] isEqual:@"Dining"]) {
events.eventsInt = 2;
[events setTitle:[eventType objectAtIndex:indexPath.row]];
}
[self.navigationController pushViewController:events animated:YES];
}

这是EventTypeViewController.m
-我没什么好说的。
#import "EventTypeViewController.h"
@interface EventTypeViewController ()
@end
@implementation EventTypeViewController
@synthesize eventsInt;

{
corporateArray = [[NSMutableArray alloc]
initWithObjects:@"Corporate 1", @"Corporate 2", @"Corporate 3", @"Corporate 4", nil];

initWithObjects:@"Dining 1", @"Dining 2", @"Dining 3", nil];
}

return 1;
}

{
if (eventsInt == 0)
return [corporateArray count];
if (eventsInt == 1)
return [socialArray count];
if (eventsInt == 2)
return [diningArray count];
[self.tableView reloadData];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

cell.textLabel.text = [[corporateArray objectAtIndex:indexPath.row]retain];
if (eventsInt == 1)
cell.textLabel.text = [[socialArray objectAtIndex:indexPath.row]retain];
if (eventsInt == 2)
cell.textLabel.text = [[diningArray objectAtIndex:indexPath.row]retain];

您的UITableViewController是否嵌入了UINavigationController?这样您就可以激活push方法。
您也可以使用segues。实施-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
,为那里的下一个控制器设置数据变量,然后使用[self performSegueWithIdentifier:(NSString *) sender:(id)sender]
