The C version of this uses an example, a weather station, in Cocoa.The program uses temperature, pressure and humidity data for three different purposes.Besides the files from Buck & Yacktman, I had eight files for my four classes: operates the window where the user types in the weather data and posts the notification when the user clicks the “Send Data” button. // #import "Ch14_Notifications App Delegate.h" #import "MYNotification Center.h" #import "MYNotification.h" @implementation Ch14_Notifications App Delegate @synthesize sensor Window; @synthesize current Window; @synthesize stats Window; @synthesize forecast Window; @synthesize current Controller; @synthesize stats Controller; @synthesize forecast Controller; @synthesize temperature Field; @synthesize pressure Field; @synthesize humidity Field; - (void)application Did Finish Launching:(NSNotification *)a Notification - (IBAction)send Data:(id)sender @end #import "MYNotification.h" @interface Current Controller : NSObject - (void)update Weather:(MYNotification *)note; @end // // Current Controller.m // Ch14 Notifications // // Created by Norm Hecht. There is some coupling between this class and the observers, since this class has to register the observers, but that occurs in a single method, @class MYNotification Center; static NSString *Temperature Key String = @"temperature"; static NSString *Pressure Key String = @"pressure"; static NSString *Humidity Key String = @"humidity"; static NSString *Weather Notification String = @"weather notification"; @interface Ch14_Notifications App Delegate : NSObject @property (assign) IBOutlet NSWindow *sensor Window; @property (assign) IBOutlet NSWindow *forecast Window; @property (assign) IBOutlet NSWindow *stats Window; @property (assign) IBOutlet NSWindow *current Window; @property (assign) IBOutlet NSObject *forecast Controller; @property (assign) IBOutlet NSObject *stats Controller; @property (assign) IBOutlet NSObject *current Controller; @property (assign) IBOutlet NSText Field *temperature Field; @property (assign) IBOutlet NSText Field *pressure Field; @property (assign) IBOutlet NSText Field *humidity Field; -(IBAction)send Data:(id)sender; @end // // Ch14_Notifications App Delegate.m // Ch14 Notifications // // Created by Norm Hecht. As noted in the post on Chapter 11, this lets the compiler find the typos for you (the string varaible named slips though unnoticed).Since the observers didn’t necessarily use all of those strings, the compiler gave a warning, even though all of them were used somewhere. Code looks like this: is only updated when the last file has been exported, so it's blank during the whole loop and gets the last file name once the loop reaches the end. I'm a total noob here, I'm wondering if the NSText Field needs a command to be updated, similarly to a table view. Since this is taking a long time, you should do this on a background thread and then update the textfield on the main thread.

So this implementation of a Singleton is flawed, because it allowed me to create a second instance.

Is there any easy way to implement this or else use NSString value to hold the previous string and set this string to NSText Filed along with new button's string value.
