All iPad figures of chapter 3 |
The figures with iPad table views in chapter 3 are so small, that they are useless. A serious problem.

Tray implementation |
- (id) initWithOwnerDevice:(id<TrayProtocol>)paramOwnerDevice {
}
self = [super init];
if (self != nil){ ownerDevice = [paramOwnerDevice retain]; /* Initially we have only 10 sheets of paper */ paperCount = 10;
} return(self);
Shouldn't the tray just assign the owner and not retain it?
if (self != nil){ ownerDevice = paramOwnerDevice; }
Note from the Author or Editor:
Hi Thomas,
I had a look at the code. The .h file declares the delegate like this:
@property (nonatomic, retain) id<TrayProtocol> ownerDevice;
Which is the issue as I can see because the owner retains the tray and tray retains the owner. You are right, this is problematic and should have actually been avoided. Thank you for submitting this.
Regards,
Vandad |
