Am archive and unarchive the uiview and display the view in ipad this controls (uiimageview,uiscrollview,uitableview,uibutton) were not displayed....but uiview subviews all controls are there ....Is it possible to get that controls(uiimageview,uiscrollview,uitableview,uibutton) in view? possible means how to get that controls to display in view.
uiview *viewForArchive; uiview *newCir=[uiview alloc ]initwithframe:cgrectmake(0,0,768,1024)];
//archiving
NSMutableData *d= [NSMutableData data];
NSKeyedArchiver *kA=[[NSKeyedArchiver alloc] initForWritingWithMutableData:d];
[kA encodeObject:newCir forKey:@"view"];
[kA finishEncoding];
if ([d writeToFile:[NSHomeDirectory() stringByAppendingPathComponent:@"archiveView"] options:NSAtomicWrite error:nil] == NO)
{
NSLog(@"writeToFile error");
}
else
{
NSLog(@"Written!");
}
//unarchiving
NSData *theData = [NSData dataWithContentsOfFile:[NSHomeDirectory() stringByAppendingPathComponent:@"archiveView"]];
NSKeyedUnarchiver *decoder = [[NSKeyedUnarchiver alloc] initForReadingWithData:theData];
NSDictionary *dict= [decoder decodeObjectForKey:@"view"];
[decoder finishDecoding];
if ([theData writeToFile:[NSHomeDirectory() stringByAppendingPathComponent:@"unarchiveView"] options:NSAtomicWrite error:nil] == NO) {
NSLog(@"writeToFile error");
}
else {
if ([dict isKindOfClass:[UIView class]]) {
viewForArchive=(UIView *)dict;
NSLog(@"view:%@",viewForArchive.subviews );
viewForArchive.backgroundColor=[UIColor whiteColor];
[self.view addsubview:viewForArchive];
}
NSLog(@"Written!");
}
this is the uiview archiver coding....
In this coding to print the viewForArchive.subviews all controls are there....in my application this controls (uiimageview,uiscrollview,uitableview,uibutton) were not displayed...what is the problem in this coding...

If your point is to save specific states of your objects, you can store strings in the NSUserDefaults and set the objects according to your strings. Alternatively, you can create the xib files, which automatically will store your objects?
