UISplitViewController与故事板
问题描述:
我使用故事板与iPad应用程序的分割视图控制器。并将其初始设置为分割视图控制器。我通过一个数组填充主视图控制器。 'feature'是NSObject类,我声明方法:UISplitViewController与故事板
- (feature *)initWithName:(NSString *)name iconName:(NSString *)iconName featuresofiphone:(iphoneFeatures)featuresofiphone;,并在.m类中定义NSString类型的名称,图标名称,featuresofiPhone的特性。 这是我在didFinishLaunchingWithOptions代码:在主视图控制器
exception 'NSRangeException', reason: '-[UITableView scrollToRowAtIndexPath:atScrollPosition:animated:]: row (0) beyond bounds (0) for section (0).'在:
NSMutableArray *monsters = [NSMutableArray array];
[monsters addObject:[[[feature alloc] initWithName:@"iphone3g"
iconName:@"iphone3g.jpg" featuresofiphone:iphone3gf] autorelease]];
[monsters addObject:[[[feature alloc] initWithName:@"iphone3gs"
iconName:@"iphone3gs.jpg" featuresofiphone:iphone3gsf] autorelease]];
[monsters addObject:[[[feature alloc] initWithName:@"iphone4g" iconName:@"iphone4g.jpg"
featuresofiphone:iphone4gf] autorelease]];
MasterViewController *masterDetailViewController = [[MasterViewController alloc]init];
masterDetailViewController.iphones = iphonesarray;
UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController;
UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
splitViewController.delegate = (id)navigationController.topViewController;
return YES;
但其给予异常
-(void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.detailViewController = (DetailViewController *)
[[self.splitViewController.viewControllers lastObject] topViewController];
[self.tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]
animated:NO scrollPosition:UITableViewScrollPositionMiddle];
}
和控制还没有达到到的cellForRowAtIndexPath - 方法。帮帮我!!

你没有足够的细胞,只是发表评论
[self.tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:NO scrollPosition:UITableViewScrollPositionMiddle];
它试图滚动到不存在的细胞线。
