iphone initializing tab bar controller view programatically
- by unsorted
I want to initialize my tab bar controller programatically, but I just get a blank screen with the code I have. I tried to imitate TheElements sample app, and stuff seems comparable going line-by-line, but obviously something's wrong. Any suggestions?
Thanks...
In main.m:
#import <UIKit/UIKit.h>
int main(int argc, char *argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, @"DubbleWrapAppDelegate");
[pool release];
return retVal;
}
In DubbleWrapAppDelegate.h:
@interface DubbleWrapAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> {
UIWindow *window;
UITabBarController *tabBarController;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UITabBarController *tabBarController;
@end
In DubbleWrapAppDelegate.m:
@implementation DubbleWrapAppDelegate
@synthesize window;
@synthesize tabBarController;
- init {
if (self = [super init]){
// initialize to nil
window = nil;
tabBarController = nil;
}
return self;
}
- (void)applicationDidFinishLaunching:(UIApplication *)application {
SafeTableViewController *vc1 = [[SafeTableViewController alloc] initWithStyle:UITableViewStylePlain];
[vc1 setSafeItems:[SafeItem knownSafeItems]]; // Set the list of known SafeItems:
UINavigationController *nc1;
nc1 = [[UINavigationController alloc] initWithRootViewController:vc1];
[vc1 release];
BoxXRayTableViewController *vc2 = [[BoxXRayTableViewController alloc] initWithStyle:UITableViewStylePlain];
UINavigationController *nc2;
nc2 = [[UINavigationController alloc] initWithRootViewController:vc2];
[vc2 release];
AboutLibertyViewController *vc3 = [[AboutLibertyViewController alloc] init];
UINavigationController *nc3;
nc3 = [[UINavigationController alloc] initWithRootViewController:vc3];
[vc3 release];
NSArray* controllers = [NSArray arrayWithObjects:nc1, nc2, nc3, nil];
tabBarController = [[UITabBarController alloc] init];
tabBarController.viewControllers = controllers;
[controllers release];
// Add the tab bar controller's current view as a subview of the window
window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
[window setBackgroundColor:[UIColor redColor]];
[window addSubview:tabBarController.view];
[window makeKeyAndVisible];
[nc1 release];
[nc2 release];
[nc3 release];
}
The plist is set so that there is no NIB file referenced.
