self.tableView.backgroundColor = [UIColor clearColor];iPhone の時にやっていた上記が効かず困っていたのだが、そういことか。
- (void)viewDidLoad {
[super viewDidLoad];
[self.tableView setBackgroundView:nil];
[self.tableView setBackgroundView:[[[UIView alloc] init] autorelease]];
self.tableView.backgroundColor = [UIColor clearColor];
透明になった。

)UISplitViewController.view の構成はこう。UIView

UILayoutContainerView
|-UINavigationTransitionView

- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[picker dismissModalViewControllerAnimated:YES];
UIImage* image = [info objectForKey:UIImagePickerControllerEditedImage];
NSError* error = nil;
NSData* data = UIImageJPEGRepresentation(image, 0.5);
[self.session sendData:data
toPeers:[NSArray arrayWithObject:self.peerID]
withDataMode:GKSendDataReliable
error:&error];
if (error) {
NSLog(@"%@", error);
}
}特別な工夫はなく UIImage を NSData に変換して送信しているだけ。- (void) receiveData:(NSData *)data fromPeer:(NSString *)peer
inSession:(GKSession *)session context:(void *)context
{
// image
NSLog(@"received image");
self.imageView.image = [UIImage imageWithData:data];
}
}これも工夫は無い。送られてきた NSData から UIImageを生成して表示しているだけ。Error Domain=com.apple.gamekit.GKSessionErrorDomain Code=30202 "Send data error."
UserInfo=0x570c1b0 {NSLocalizedFailureReason=AGPSessionSendTo failed (801C0001).,
NSLocalizedDescription=Send data error.}メモリが不足していたのでそれに関連してエラーが出たのかもしれない。2010年12月9日木曜日 | Published in Bluetooth, GameKit, iOS 4.2, iPad, iPhone, サンプルあり | 0 コメント
- (IBAction)connect:(id)sender
{
GKPeerPickerController* picker = [[GKPeerPickerController alloc] init];
picker.delegate = self;
picker.connectionTypesMask = GKPeerPickerConnectionTypeNearby;
[picker show];
}インスタンスを作り、-[show] を投げると接続に必要なダイアログが表示される。
- (void)peerPickerController:(GKPeerPickerController *)picker
didConnectPeer:(NSString *)peerID toSession:(GKSession *)session
{
self.peerID = peerID;
self.session = session;
session.delegate = self;
[session setDataReceiveHandler:self withContext:nil];
picker.delegate = nil;
[picker dismiss];
[picker autorelease];
}- (IBAction)sendText:(id)sender
{
NSData* data = [self.sendText.text dataUsingEncoding:NSUTF8StringEncoding];
NSError* error = nil;
[self.session sendData:data
toPeers:[NSArray arrayWithObject:self.peerID]
withDataMode:GKSendDataReliable
error:&error];
if (error) {
NSLog(@"%@", error);
}
self.sendText.text = @"";
}次に受け側。receiveData:fromPeer:inSession:context: を実装する。ここでは渡ってきた NSData を UTF8でデコードして NSStringに戻し、画面上の UITextView へ表示している。- (void) receiveData:(NSData *)data fromPeer:(NSString *)peer inSession: (GKSession *)session context:(void *)context NSString* msg = [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease]; NSString* text = [self.textView.text stringByAppendingFormat:@"%@\n", msg]; self.textView.text = text; }
