Adding a UILabel to a UIToolbar

Question

I\'m trying to add a label to my toolbar. Button works great, however when I add the label object, it crashes. Any ideas?

UIBarButtonItem *setDateRangeButton

One of the things I'm using this trick for is to instantiate a UIActivityIndicatorView on top of the UIToolBar, something that otherwise wouldn't be possible. For instance here I have a UIToolBar with 2 UIBarButtonItem, a FlexibleSpaceBarButtonItem, and then another UIBarButtonItem. I want to insert a UIActivityIndicatorView into the UIToolBar between the flexible space and the final (right-hand) button. So in my RootViewController I do the following,

- (void)viewDidLoad {
[super viewDidLoad];// Add an invisible UIActivityViewIndicator to the toolbar
UIToolbar *toolbar = (UIToolbar *)[self.view viewWithTag:767];
NSArray *items = [toolbar items];

activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 20.0f, 20.0f)];
[activityIndicator setActivityIndicatorViewStyle:UIActivityIndicatorViewStyleWhite];    

NSArray *newItems = [NSArray arrayWithObjects:[items objectAtIndex:0],[items objectAtIndex:1],[items objectAtIndex:2],
                     [[UIBarButtonItem alloc] initWithCustomView:activityIndicator], [items objectAtIndex:3],nil];
[toolbar setItems:newItems];}
