我已经在堆栈溢出上阅读了很长一段时间，但这是我的第一篇文章，只是因为这是我第一次遇到其他人似乎没有修复过的问题！
好的，直到生意。将UITableViews放在UIPageView中应该是一件简单的事情，但我遇到了困难。我有一个ViewController和contentViewController。我使用.xibs而不是故事板。 contentViewController.xib是一个Table View，ViewController.xib是一个View。我只专注于iPhone。 UITableView连接到名为theTableView的dataSource，delegate和Referencing Outlet。
项目构建但是当我运行它时，我收到以下错误消息：

libc++abi.dylib: terminate called throwing an exception
这在ViewController.m中的 - （void）viewDidLoad {}之后崩溃，我还没有学习如何修复auto layout / layoutSubview错误。还有其他人知道吗？
我对ios开发的经验有限，所以我确信我在正确的位置上没有合适的部分。我使用http://www.techotopia.com/index.php/An_Example_iOS_5_iPhone_UIPageViewController_Application来实现这一目标。
我的代码如下：
ViewController.h
#import <UIKit/UIKit.h>
#import "contentViewController.h"
@interface ViewController : UIViewController
<UIPageViewControllerDataSource>
{
UIPageViewController *pageController;
NSArray *pageContent;
}
@property (strong, nonatomic) UIPageViewController *pageController;
@property (strong, nonatomic) NSArray *pageContent;
@end
ViewController.m
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
@synthesize pageController, pageContent;
- (contentViewController *)viewControllerAtIndex:(NSUInteger)index
{
// Return the data view controller for the given index.
if (([self.pageContent count] == 0) || (index >= [self.pageContent count])) {
return nil;
}
// Create a new view controller and pass suitable data.
contentViewController *dataViewController =[[contentViewController alloc]initWithNibName:@"contentViewController"bundle:nil];
dataViewController.dataObject =[self.pageContent objectAtIndex:index];
return dataViewController;
}
- (NSUInteger)indexOfViewController:(contentViewController *)viewController
{
return [self.pageContent indexOfObject:viewController.dataObject];
}
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController
{
NSUInteger index = [self indexOfViewController:(contentViewController *)viewController];
if ((index == 0) || (index == NSNotFound)) {
return nil;
}
index--;
return [self viewControllerAtIndex:index];
}
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController
{
NSUInteger index = [self indexOfViewController:(contentViewController *)viewController];
if (index == NSNotFound) {
return nil;
}
index++;
if (index == [self.pageContent count]) {
return nil;
}
return [self viewControllerAtIndex:index];
}
- (void) createContentPages
{
NSMutableArray *pageStrings = [[NSMutableArray alloc] init];
for (int i = 1; i < 4; i++)
{
NSString *contentString = [[NSString alloc]initWithFormat:@"Chapter %d \nThis is the page %d of content displayed using UIPageViewController in iOS 5.", i, i];
[pageStrings addObject:contentString];
}
pageContent = [[NSArray alloc] initWithArray:pageStrings];
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self createContentPages];
self.pageController = [[UIPageViewController alloc]initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];
pageController.dataSource = self;
[[pageController view] setFrame:[[self view] bounds]];
contentViewController *initialViewController = [self viewControllerAtIndex:0];
NSArray *viewControllers = [NSArray arrayWithObject:initialViewController];
[pageController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];
[self addChildViewController:pageController];
[[self view] addSubview:[pageController view]];
[pageController didMoveToParentViewController:self];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
contentViewController.h
#import <UIKit/UIKit.h>
@interface contentViewController : UIViewController
@property (strong, nonatomic) IBOutlet UITableView *theTableView;
@property (strong, nonatomic) id dataObject;
@property (strong, nonatomic) NSArray *pageContent;
@end

#import "contentViewController.h"
@interface contentViewController ()
@end
@implementation contentViewController
@synthesize theTableView, dataObject, pageContent;
- (void)viewWillAppear:(BOOL)animated
{

}
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{

return self;
}
- (void) createContentPages

{

}
- (void)viewDidLoad
{
[super viewDidLoad];
[self createContentPages];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection (NSInteger)section
{
return 4;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath (NSIndexPath *)indexPath
{

cell.textLabel.text = [pageContent objectAtIndex:indexPath.row];
return cell;

}
@end
所以如果有人能理顺我，我会很感激。
答案 0 :(得分：1)
我能够解决自己的问题，看起来我只是有些混乱。
rdelmar的评论让我走上了正确的轨道，但我将委托和数据源挂钩到了错误的对象。我必须将它们连接到文件所有者才能使其正常工作。
此外，似乎theTableView不是必需的，当我删除时，我的代码突然按预期工作。
如果这还不够清楚，请告诉我如何更具体。谢谢！
