- (void)viewDidLoad{
UIView *baseView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
[self.view addSubview:baseView];
// Displays UIImageView
UIImageView *myImage = [[UIImageView alloc]
initWithImage:[UIImage imageNamed:@"ka1_046.png"]];
myImage.frame = CGRectMake(0, 0, 320, 460);
[baseView addSubview:myImage];
// create the UIToolbar at the bottom of the view controller
toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 425, 320, 40)];
toolbar.barStyle = UIBarStyleBlackOpaque;
[baseView addSubview:toolbar];
我怎样才能使没有导航控制器和 tabbarcontroller 的 Main VC 的 UIToolbar 对所有 VC 都是全局的
