When initiating a view from a UIActionSheet button, upon returning to the view via the navigationBar back button, the toolbar while still visible does not have any of the buttons that were previously on it. This error has arisen since updating to iOS 6 and occurs while testing it on the simulator and a device running iOS 6 only. If I comment out the code that hides the toolbar on the view pushed by the UIActionSheet the buttons are added when going back.
I’m making my toolbar items programatically in viewWillAppear and showing the UIActionSheet from the toolbar which I’m accessing via self.navigationController.toolbar.
Any idea what is causing this problem? It’s only happened since iOS 6 has come around so is there any changes that I need to take into account regarding viewWillAppear?
This is how the view is pushed from the actionSheet:
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (actionSheet.tag == 2) {
if (buttonIndex == 0) {
[self dismissAllTips];
self.actionNoteAddView= [[self.storyboard instantiateViewControllerWithIdentifier:@"IDActionNoteAddView"] retain];
actionNoteAddView.note_id = 0;
actionNoteAddView.iscompleted=0;
[[NSUserDefaults standardUserDefaults] setBool:NO forKey:@"tool_tips"];
[self.navigationController pushViewController:actionNoteAddView animated:TRUE];
[actionNoteAddView release];
}else if(buttonIndex == 1){
...
These are the view methods for the pushed view:
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
self.navigationItem.hidesBackButton = NO;
[self.navigationController setToolbarHidden:YES];
txtcontent.layer.cornerRadius = 10.0f;
}
-(void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
}
These are the view methods for the view that pushed the view using the actionSheet:
- (void) viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
self.navigationItem.hidesBackButton = YES;
[self.navigationController setToolbarHidden:NO];
self.navigationController.navigationBarHidden=NO;
self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.8 green:0.45 blue:0.2 alpha:1];
self.navigationController.toolbar.barStyle = UIBarStyleBlackOpaque;
self.navigationController.toolbar.tintColor = [UIColor colorWithRed:0.8 green:0.45 blue:0.2 alpha:1];
UIImage *actionButtonImage = [UIImage imageNamed:@"31-circle-plus@2x.png"];

UIBarButtonItem *dashButton = [[UIBarButtonItem alloc] initWithImage:dashButtonImage style:UIBarButtonItemStylePlain target:self action:@selector(settingsPressed:)];
UIBarButtonItem *flexItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
NSArray *toolitems = [NSArray arrayWithObjects:dashButton, flexItem, actionButton, flexItem, nil];
[self setToolbarItems:toolitems];
self.title = @"Dashboard";
defaultProfile.text = [[NSUserDefaults standardUserDefaults] stringForKey:@"default_profile"];
BOOL dailyProcess = [[NSUserDefaults standardUserDefaults] boolForKey:@"daily_process"];
if(dailyProcess){
[[NSUserDefaults standardUserDefaults] setBool:NO forKey:@"daily_process"];
[[NSUserDefaults standardUserDefaults] synchronize];
loading = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
labelProcess = [[UILabel alloc]initWithFrame:CGRectMake(60, 105, 240, 30)];
labelProcess.text = @"Processing...";
labelProcess.backgroundColor = [UIColor clearColor];
labelProcess.textColor=[UIColor colorWithRed:0.8 green:0.45 blue:0.2 alpha:1];
[labelProcess setFont:[UIFont systemFontOfSize:20]];
loading.opaque = NO;
loading.backgroundColor = [UIColor colorWithWhite:0.0f alpha:0.6f];
indicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
[indicator setHidesWhenStopped:YES];
indicator.center = self.view.center;
[self.view addSubview:loading];
[self.view addSubview:indicator];
[self.view addSubview:labelProcess];
[indicator startAnimating];
}
}
-(void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
CGRect frame = CGRectMake(157, 365, 10, 10);
UIView *viewToPointAt = [[UIView alloc] initWithFrame:frame];
[self.view addSubview:viewToPointAt];
BOOL willies = [[NSUserDefaults standardUserDefaults] boolForKey:@"tool_tips"];
if(willies==YES){
if(popTip == nil) {
popTip = [[[CMPopTipView alloc] initWithMessage:@"Step 1/3: This is the Action Button. You can create, view and auto-fill notes which are then added to your timeline.(Click for step 2)."] autorelease];
popTip.delegate = self;
[popTip presentPointingAtView:viewToPointAt inView:self.view animated:YES];
popTip.backgroundColor = [UIColor colorWithRed:0.8 green:0.45 blue:0.2 alpha:1];
popTip.textColor = [UIColor whiteColor];
}
}
[viewToPointAt release];
}
Tried a lot of different techniques and eventually sorted it by showing it in one view method and hiding it in the next. It’s one fo the strangest bugs I have encountered and this is hardly a fix, but I hate having unanswered questions.
