UISplitView在DetailView中具有多个ViewController(情节提要)

在寻找答案的过程中,我发现许多人都有同样的问题。我自己想好了,所以这里是我的解决方案。我希望它对其他人有用。

步骤1。 创建SplitViewController项目。如果您已经有项目,请跳过此步骤;)

步骤2。 添加两个不同的视图控制器。在本例中,我称它们为AbcViewController和XyzViewController。

步骤3。 转到ipad情节提要,从情节提要中删除DetailViewController。然后添加两个新的viewController。

步骤4。 设置viewControllers的类和情节提要ID。

步骤5。 转到MasterViewController.h并用以下代码替换代码。

#import <UIKit/UIKit.h>

@class AbcViewController;
@class XyzViewController;

@interface MasterViewController : UITableViewController

@property (strong, nonatomic) AbcViewController *abcViewController;
@property (strong, nonatomic) XyzViewController *xyzViewController;

@end

步骤6。 现在转到MasterViewController.m文件并替换为以下代码:

注: 如果您有一个现有项目并且不想替换,请使用步骤7中的代码。

#import "MasterViewController.h"
#import "DetailViewController.h"

@interface MasterViewController () {
    NSMutableArray *_objects;
}
@end

@implementation MasterViewController

- (void)awakeFromNib
{
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
        self.clearsSelectionOnViewWillAppear = NO;
        self.preferredContentSize = CGSizeMake(320.0, 600.0);
    }
    [super awakeFromNib];
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.detailViewController = (DetailViewController*)[[self.splitViewController.viewControllers lastObject] topViewController];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Table View

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return 2;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];

    if (indexPath.row == 0) {
        cell.textLabel.text = @"ABC";
    }
    if (indexPath.row == 1) {
        cell.textLabel.text = @"XYZ";
    }

    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    self.abcViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"ABC"];
    self.xyzViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"XYZ"];
    if (indexPath.row == 0) {
        NSArray *newVCs = [NSArray arrayWithObjects:[[[self splitViewController ] viewControllers ] firstObject ] , self.abcViewController, nil];
        self.splitViewController.viewControllers = newVCs;
    }
    if (indexPath.row == 1) {
        NSArray *newVCs = [NSArray arrayWithObjects:[[[self splitViewController ] viewControllers ] firstObject ] , self.xyzViewController, nil];
        self.splitViewController.viewControllers = newVCs;
    }
}

@end

步骤7。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    {
        self.abcViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"ABC"];
        self.xyzViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"XYZ"];

        if (indexPath.row == 0) {
            NSArray *newVCs = [NSArray arrayWithObjects:[[[self splitViewController ] viewControllers ] firstObject ] , self.abcViewController, nil];
            self.splitViewController.viewControllers = newVCs;
        }
        if (indexPath.row == 1) {
            NSArray *newVCs = [NSArray arrayWithObjects:[[[self splitViewController ] viewControllers ] firstObject ] , self.xyzViewController, nil];
            self.splitViewController.viewControllers = newVCs;
        }
    }

就这样,运行您的项目并享受:)
