I created a small simple project with a button and a progress bar. I
subclassed NSObject then added an action and a outlet. I then instantiated
the new class and control dragged from the object to the progress bar to
connect to create the connect for the outlet. Then I control dragged from
the button to the object to connect it to the action. After that I created
the two files (.h & .m) in the project. When I click the button nothing
happens and am totally lost. Attached below is the code, any help would be
greatly appreciated. Thanks in advance.
/* progress_bar (.h file) */
#import <Cocoa/Cocoa.h>
@interface progress_bar : NSObject
{
IBOutlet id progressView;
NSTimer *timer;
}
- (IBAction)pushedButton:(id)sender;
@end
// beginning of .m file
#import "progress_bar.h"
@implementation progress_bar
- (void)awakeFromNib
{
srandom(time(NULL));
}
- (IBAction)pushedButton:(id)sender
{
if([sender state] == 1)
{
NSLog(@"Starting");
timer = [[NSTimer scheduledTimerWithTimeInterval:0.2 target:self
selector:@selector(checkTime:) userInfo:nil repeats:YES] retain];
} else {
NSLog(@"Stopping");
[timer invalidate];
[timer release];
}
}
- (void) checkTime: (NSTimer *) aTimer
{
NSLog(@"check");
[progressView incrementBy:10];
}
@end
