这是我的故事板:
我的滚动视图包含 3 个 NavigationController(包含 BubbleListController,它是一种表视图)。这 3 个视图彼此放在一边,这是代码:
ioBubbleListController.h
#import <UIKit/UIKit.h>
@interface ioBubbleListController : UITableViewController {
NSDictionary *bubbles;
}
@end
ioBubbleListController.m
#import "ioBubbleListController.h"
@interface ioBubbleListController ()
@property (nonatomic, retain) NSDictionary *bubbles;
@end
@implementation ioBubbleListController
@synthesize bubbles;
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
[super viewDidLoad];
self.bubbles = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"bubbles" ofType:@"plist"]];
// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [self.bubbles count];
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
return [[self.bubbles allKeys] objectAtIndex:section];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSString *continent = [self tableView:tableView titleForHeaderInSection:section];
return [[self.bubbles valueForKey:continent] count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"CountryCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell...
NSString *continent = [self tableView:tableView titleForHeaderInSection:indexPath.section];
NSString *country = [[self.bubbles valueForKey:continent] objectAtIndex:indexPath.row];
cell.textLabel.text = country;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *continent = [self tableView:tableView titleForHeaderInSection:indexPath.section];
NSString *country = [[self.bubbles valueForKey:continent] objectAtIndex:indexPath.row];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil
message:[NSString stringWithFormat:@"You selected %@!", country]
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
@end
这是我的ioUIPager将一个 BubbleList 放在另一个旁边
#import "ioUIPager.h"
@implementation ioUIPager
@synthesize scrollView;
- (void)viewDidLoad {
[super viewDidLoad];
[self scrollView].contentSize = CGSizeMake(self.scrollView.frame.size.width * 3, self.scrollView.frame.size.height);
UIStoryboard *sb = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
// View1
UITableViewController *view1 = [sb instantiateViewControllerWithIdentifier:@"BubblesList"];
CGRect frame1;
frame1.origin.x = self.scrollView.frame.size.width * 0;
frame1.origin.y = 0;
frame1.size = self.scrollView.frame.size;
[self.scrollView addSubview:view1.view];
view1.view.frame = frame1;
view1.view.backgroundColor = [UIColor greenColor];
// View2
UIViewController *view2 = [sb instantiateViewControllerWithIdentifier:@"BubblesList"];
CGRect frame2;
frame2.origin.x = self.scrollView.frame.size.width * 1;
frame2.origin.y = 0;
frame2.size = self.scrollView.frame.size;
[self.scrollView addSubview:view2.view];
view2.view.frame = frame2;
view2.view.backgroundColor = [UIColor redColor];
// View2
UIViewController *view3 = [sb instantiateViewControllerWithIdentifier:@"BubblesList"];
CGRect frame3;
frame3.origin.x = self.scrollView.frame.size.width * 2;
frame3.origin.y = 0;
frame3.size = self.scrollView.frame.size;
[self.scrollView addSubview:view3.view];
view3.view.frame = frame3;
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
self.scrollView = nil;
}
//- (void)dealloc {
// [scrollView release];
// [super dealloc];
//}
@end
乍一看,一切都很好,但是我在 UITableView/ioBubbleList 上所做的任何手势/触摸/点击,每个单元格都会像这样消失:
如果从故事板我从导航器控制器开始,那么一切正常。有什么提示吗?
