我正在尝试创建一个SplitViewController视图但是我收到以下警告：
属性splitViewController需要定义setSplitViewController方法-use @ Synthesize，@ dynamic或在此类实现中提供方法实现。
以下是代码
///AppDelegate.h
@class ViewController;
@class DetailViewController;
@interface AppDelegate : UIResponder <UIApplicationDelegate, UISplitViewControllerDelegate>
{
UISplitViewController *splitViewController;
ViewController *viewcontroller;
DetailViewController *detailViewController;
}
@property (nonatomic,retain) UIWindow *window;
@property (nonatomic,retain) DetailViewController *detailViewController;
@property(nonatomic,retain) UISplitViewController *splitViewController;
@property (nonatomic,retain) ViewController *viewController;
@end
///AppDelegate.m"
#import "ViewController.h"
#import "DetailViewController.h"
@implementation AppDelegate
@synthesize window = _window;
@synthesize viewController = _viewController;
@synthesize splitviewController;
@synthesize detailViewController;
- (void)dealloc
{
[_window release];
[_viewController release];
[super dealloc];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
ViewController *rootViewController = [[ViewController alloc] initWithStyle:UITableViewStylePlain];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailView" bundle:nil];
rootViewController.detailViewController = detailViewController;
splitViewController = [[UISplitViewController alloc] init];
splitViewController.viewControllers = [NSArray arrayWithObjects:navigationController, detailViewController, nil];
splitViewController.delegate = detailViewController;
[self.window makeKeyAndVisible];
return YES;
}
///ViewController.h
#import <UIKit/UIKit.h>
@class DetailViewController;
@interface ViewController : UITableViewController{
DetailViewController *detailViewController;
NSMutableArray *phone;
}
@property (nonatomic,retain)IBOutlet DetailViewController *detailViewController;
@property (nonatomic,retain) NSMutableArray *phone;
@end
///ViewController.m
#import "ViewController.h"
#import "DetailViewController.h"
@interface ViewController ()
@end
@implementation ViewController
@synthesize detailViewController,phone;
- (CGSize)contentSizeForViewInPopoverView {
return CGSizeMake(320, 600);
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.phone = [[NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"phone" ofType:@"plist"]] retain];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)aTableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)aTableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return [phone count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"CellIdentifier";
// Dequeue or create a cell of the appropriate type.
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
cell.accessoryType = UITableViewCellAccessoryNone;
}
// Configure the cell.
cell.textLabel.text = [self.phone objectAtIndex:indexPath.row];
return cell;
}
- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
/*
When a row is selected, set the detail view controller's detail item to the item associated with the selected row.
*/
detailViewController.detailItem = [self.phone objectAtIndex:indexPath.row];
}
- (void)dealloc {
[detailViewController release];
[super dealloc];
}

问题是你的@synthesize语句中拼写错误的splitViewController - 你没有把v大写。
如果您以简单的方式完成此操作，则不会遇到此问题。不再需要实例变量或@synthesize语句 - 在创建属性时自动获得两者。

在您的情况下，添加@synthesize splitViewController = _splitViewController; 和 detailViewController = _ detailViewController;
以下是有用的代码，如何添加UISplitViewController。
/// AppDelegate.h file
#import <UIKit/UIKit.h>
#import "MasterViewController.h"
#import "DetailViewController.h"
@interface AppDelegate : UIResponder <UIApplicationDelegate, UISplitViewControllerDelegate>
@property (strong, nonatomic) UIWindow *window;
@property (nonatomic, strong) UISplitViewController *splitViewController;
@property (nonatomic, strong) MasterViewController *masterVC;
@property (nonatomic, strong) DetailViewController *detailVC;
@property (nonatomic, strong) UINavigationController *mvcNavCon;
@property (nonatomic, strong) UINavigationController *dvcNavCon;
@end
/// AppDelegate.m File
#import "AppDelegate.h"
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
self.masterVC = [[MasterViewController alloc] init];
self.mvcNavCon = [[UINavigationController alloc] initWithRootViewController:self.masterVC];
self.detailVC = [[DetailViewController alloc] init];
self.dvcNavCon = [[UINavigationController alloc] initWithRootViewController:self.detailVC];
self.splitViewController = [[UISplitViewController alloc] init];
self.splitViewController.delegate = self;
self.splitViewController.viewControllers = [NSArray arrayWithObjects:self.mvcNavCon, self.dvcNavCon,nil];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = self.splitViewController;
[self.window makeKeyAndVisible];
return YES;
}

在您的密码中，您还没有合成您的splitViewController媒体资源。由于您尚未将其合成为属性，因此编译器会发出警告，要求您合成属性，以便它可以自动为您的信任生成setter和getter（您可以使用生成的setter和getter使用.表示法如在self.splitViewController中那样将其合成为
@synthesize splitViewController = _splitViewController
或
将您自己的自定义setter和getter实现为
//setter
- (void)setSplitViewController:(UISplitViewController*)splitViewController_ {
//assuming your property has retain identifier
if (splitViewController != splitViewController_) {
[splitViewController release];
splitViewController = [splitViewController_ retain];
}
}
//getter
- (UISplitViewController*)splitViewController {
return splitViewController;
}
或
使用@dynamic splitViewController将属性声明为动态。这意味着该属性的setter和getter将从其他地方提供。
修改
使用以下内容替换appDelegate.m中的didFinishLaunchingWithOptions方法：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
_viewController = [[ViewController alloc] initWithNibName:@"ViewController's nib name" bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:_viewController];
detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailView" bundle:nil];
rootViewController.detailViewController = detailViewController;
splitViewController = [[UISplitViewController alloc] init];
splitViewController.viewControllers = [NSArray arrayWithObjects:navigationController, detailViewController, nil];
splitViewController.delegate = detailViewController;
self.window.rootViewController = splitViewController;
return YES;
}
还编辑dealloc：
- (void)dealloc
{
[_window release];
[_viewController release];
[splitViewController release];
[detailViewController release];
[super dealloc];
}
在viewController viewDidLoad中将self.phones替换为
self.phone = [[NSArray arrayWithObjects：@＆＃34; Cell ONE＆＃34;，@＆＃34; Cell TWO＆＃34;，@＆＃34; Cell THREE＆＃34;，@＆＃34; Cell FOUR＆＃34;，@＆＃34; Cell FIVE＆＃34;，@＆＃34; Cell SIX＆＃34;，nil];
这仅用于测试阵列部件是否正确加载..因此，如果要创建单元格，您可以看到它们。在cellForRowAtIndexPath方法中设置一个断点并查看它是否被称为
然后最后在didSelect看看detailItem iVar是不是nil。
是的，在加载之前检查NIB名称，并确保NIB中的所有插座都正确连接。
干杯，玩得开心。
