我在iPad上使用UISplitViewController for app。第一项任务是以纵向模式显示主视图和详细视图。我这样做了:
// It is possible to keep the Master View in portrait mode
// also. Just pass YES to this method to enable this mode.
- (id) initWithMasterInPortraitMode:(BOOL) masterInPortrait {
self = [super init];
self.keepMasterInPortraitMode = masterInPortrait;
return self;
}
// Thanks to http://intensedebate.com/profiles/fgrios for this code snippet
-(void) viewWillAppear:(BOOL)animated {
NSLog(@"viewWillAppear");
if(keepMasterInPortraitMode == NO) {
return;
}
//check interface orientation at first view and adjust it
//if it is in portrait mode
if (self.interfaceOrientation == UIInterfaceOrientationPortrait || self.interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
UIViewController* master = [self.viewControllers objectAtIndex:0];
UIViewController* detail = [self.viewControllers objectAtIndex:1];
[self setupPortraitMode:master detail:detail];
}
}
// Thanks to http://intensedebate.com/profiles/fgrios for this code snippet
- (void)setupPortraitMode:(UIViewController*)master detail:(UIViewController*)detail {
//adjust master view
CGRect f = master.view.frame;
f.size.width = 320;
f.size.height = 1024;
f.origin.x = 0;
f.origin.y = 0;
[master.view setFrame:f];
//adjust detail view
f = detail.view.frame;
f.size.width = 448;
f.size.height = 1024;
f.origin.x = 321;
f.origin.y = 0;
[detail.view setFrame:f];
}
我像这样创建splitView:
MySplitViewController *mySplitViewController = [[MySplitViewController alloc] initWithMasterInPortraitMode:YES];
好的,这样就行了,当我以纵向模式启动应用程序时,它会同时显示主视图和详细视图。
现在一切都有效。但我想在主视图中为每个记录(行)显示详细视图中的不同视图。 masterView中的didSelectRowAtIndexPath方法如下所示:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row == 0) {
FirstDetailViewController *firstDetailView = [[FirstDetailViewController alloc] initWithNibName:@"firstDetailView" bundle:nil];
UINavigationController *firstDetailNavigationController = [[UINavigationController alloc] initWithRootViewController:firstDetailView];
[firstDetailView release];
[self.splitViewController setViewControllers:[NSArray arrayWithObjects:self.navigationController, firstDetailNavigationController, nil]];
}
else {
SecondDetailViewController *secondDetailView = [[SecondDetailViewController alloc] initWithNibName:@"secondDetailView" bundle:nil];
UINavigationController *secondDetailNavigationController = [[UINavigationController alloc] initWithRootViewController:secondDetailView];
[secondDetailView release];
[self.splitViewController setViewControllers:[NSArray arrayWithObjects:self.navigationController, secondDetailNavigationController, nil]];
}
}
在第一行或第二行(在masterView中)单击(触摸)后,splitView仅显示没有masterView的detailView(整个屏幕)。
如何强制splitView在更改视图,主视图和详细视图时显示???
感谢您的帮助!
答案 0 :(得分:0)
我找到了解决方案。在masterView中,我创建了splitViewController实例并将本地实例分配给该实例:
settingsSplitViewController = (SettingsSplitViewController *)self.splitViewController;
在方法didSelectRowAtIndexPath中,我这样做:
[settingsSplitViewController setupPortraitMode:self.navigationController detail:detailNavigationController];
希望能帮助别人解决这类问题。
