Im trying to make my own calendar similar to iCal and all is going well except for one thing. I plan to have the calendar selection up the top then a table list down the bottom. I can do this but then the calendar is in the same subview as the table and scrolls with it. Although I am currently not using a nib if I build it in a nib then the table wont resize to take up whatever the calendar doesn't. ie it should be larger in say February where as December will be small (exactly like the apple iCal version) I have seen other apps do this. Any ideas on how I would go about this?
Add the tableview and the calendar view separately to the main view.
Example:
- (void)loadView {
[super loadView];
UIView *topView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 100)];
topView.backgroundColor = [UIColor darkGrayColor];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 20, 280, 60)];
label.text = #"Stationary top view";
label.textColor = [UIColor whiteColor];
label.backgroundColor = [UIColor clearColor];
label.textAlignment = UITextAlignmentCenter;
[topView addSubview:label];
[label release];
[self.view addSubview:topView];
[topView release];
UITableView *tableview = [[UITableView alloc] initWithFrame:CGRectMake(0, 100, 320, 380) style:UITableViewStyleGrouped];
tableview.delegate = self;
tableview.dataSource = self;
[self.view addSubview:tableview];
[tableview release];
}

I am trying to customize my tableView in my IOS app. When my tableView(or rather array) is empty, I want to display a customized label instead of the items in the tableView. The label I am referring to is "label0". But something is terribly wrong, my [label0 setHidden:YES]; or [label0 setHidden:NO]; only works in the first block of the if "method"? In the second block (if else) nothing happens no matter what I try to set the label as (hidden or shown).
What have I missed? I cannot see my own fault?
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease];
UILabel *label0 = [[[UILabel alloc] initWithFrame:CGRectMake(0, 25, tableView.bounds.size.width - 0, 100)] autorelease];
if ([self.searchResults count] == 0){
headerView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"lista2.png"]];
UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(5, 3, tableView.bounds.size.width - 5, 18)] autorelease];
label.text = #"Information";
label.textColor = [UIColor whiteColor];
label.backgroundColor = [UIColor clearColor];
[headerView addSubview:label];
label0.text = #"Test test test";
label0.textColor = [UIColor blackColor];
label0.backgroundColor = [UIColor whiteColor];
[tableView addSubview:label0];
[label0 setHidden:NO];
}
else {
headerView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"lista2.png"]];
UILabel *label2 = [[[UILabel alloc] initWithFrame:CGRectMake(5, 3, tableView.bounds.size.width - 5, 18)] autorelease];
label2.text = #"Search results";
label2.textColor = [UIColor whiteColor];
label2.backgroundColor = [UIColor clearColor];
[headerView addSubview:label2];
[label0 setHidden:YES];
}
return headerView;
}
EDIT
I have moved the code to viewDidLoad and set the property for the UILabel. This have unfortunately not solved my problem....
UILabel *label0 = [[[UILabel alloc] initWithFrame:CGRectMake(0, 25, tableView.bounds.size.width - 0, 100)] autorelease];
[tableView addSubview:label0];
if ([self.searchResults count] == 0){
label0.text = #"Test test test";
label0.textColor = [UIColor blackColor];
label0.backgroundColor = [UIColor whiteColor];
[label0 setHidden:NO];
}
else {
[label0 setHidden:YES];
}
This is because your label0 is created every time this method is called so in "else" you are referring to totally different object (not the one that you added to tableView when array was empty).
You shouldn't be adding subviews to tableView from this method. Consider using viewDidLoad. That way you will be adding label0 only once. To achieve that add label0 as property of your viewController.
You forgot to add label0 as subview please put this line in the else statement
[tableView addSubview:label0];
also I cannot see any benefit from doing so. I believe you can just hide the table view and show another view that has the label. but nesting views that way is not good when you come back to debug this code after 1 month you will struggle to understand it.
You say in your edit that you set the property for the UILabel (I assume you mean that you have a property called label0?). If this is so, then when you alloc init your label, it should be self.label0 = ..... not UILabel *label0 = .....
I am trying to add a UILabel programmatically into my UIToolBar but it dose not seem to be appearing. This is what I am doing with my code.
- (void) viewWillAppear:(BOOL)animated
{
// Create custom toolbar at top of screen under navigation controller
[matchingSeriesInfoToolBar setFrame:CGRectMake(0, 60, 320, 30)];
matchingSeriesInfoToolBar = [UIToolbar new];
[matchingSeriesInfoToolBar sizeToFit];
CGFloat toolbarHeight = 30;
CGRect mainViewBounds = [[UIScreen mainScreen] applicationFrame];
[matchingSeriesInfoToolBar setFrame:CGRectMake(CGRectGetMinX(mainViewBounds), 0, CGRectGetWidth(mainViewBounds), toolbarHeight)];
matchingSeriesInfoToolBar.tintColor = [UIColor darkGrayColor];
[self.view addSubview:matchingSeriesInfoToolBar];
// Create size of uitableview (to fit toolbar.
[matchingSeriesTableView setFrame:CGRectMake(0, 30, self.view.frame.size.width, self.view.frame.size.height - 30)];
[self.view addSubview:matchingSeriesTableView];
// Ad UILabel to the toolbar
UIBarButtonItem *textFieldItem = [[UIBarButtonItem alloc] initWithCustomView:manufSelectionLabel];
matchingSeriesInfoToolBar.items = [NSArray arrayWithObject:textFieldItem];
manufSelectionLabel.text = #"Hello World!";
[super viewWillAppear:animated];
}
So pretty much I have created a custom toolbar which I have changed the usual location from the bottom of the screen, to appear under the UINavigationController, this is also added to the view like this so it animated properly in the view transitions..
After which I create the size of the tableview so that it appears after the custom toolbar..
then from there I am trying to add a UILabel to the toolbar.. but for some reason its not working out.
Any help would be greatly appreciated.
You must actually create the label somewhere. This code works just fine.
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
[self.view addSubview:toolbar];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];
label.backgroundColor = [UIColor clearColor];
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:label];
toolbar.items = [NSArray arrayWithObject:item];
label.text = #"Hello World";
In the code you posted you don't ever make a UILabel. Your comment says Ad UILabel to the toolbar but you then proceed to make a UIBarButtonItem with a custom view manufSectionLabel.
Where is the code which creates manufSectionLabel?
PS This line does nothing :
[matchingSeriesInfoToolBar setFrame:CGRectMake(0, 60, 320, 30)];
because at that point matchingSeriesInfoToolbar is nil - you haven't made it yet!
I have an application with navigation controller and some table view controller. In table view controller I have a two section header my definitions:
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
if (section == 0) {
UIView* customView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 74)];
UIImageView *myImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"toolbarTopBack.png"]];
UILabel *headline = [[UILabel alloc] initWithFrame:CGRectMake(11, 14, 305, 21)];
headline.backgroundColor = [UIColor clearColor];
headline.textColor = [UIColor whiteColor];
headline.font = [UIFont fontWithName:#"Helvetica Neue" size:21];
headline.text = searchPosition;
UILabel *subHeadline = [[UILabel alloc] initWithFrame:CGRectMake(11, 36, 305, 21)];
subHeadline.backgroundColor = [UIColor clearColor];
subHeadline.textColor = [UIColor grayColor];
subHeadline.font = [UIFont fontWithName:#"Helvetica Neue" size:16];
subHeadline.text = searchRegion;
[customView addSubview:myImageView];
[customView addSubview:headline];
[customView addSubview:subHeadline];
return customView;
} else {
// create the parent view that will hold header Label
UIView *customView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 44)];
customView.userInteractionEnabled = YES;
UIImageView *myImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"mainToolBar.png"]];
UIToolbar *topToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 44)];
topToolbar.barStyle = UIBarStyleDefault;
[topToolbar setBackgroundColor:[UIColor clearColor]];
static dispatch_once_t onceToken; dispatch_once(&onceToken, ^{
NSMutableDictionary *appSettingsData = [[NSMutableDictionary alloc] initWithDictionary:[appDelegate getAppStrings]];
NSArray *segmentItems = [NSArray arrayWithObjects:[NSString stringWithFormat:#"%# (%d)", [appSettingsData valueForKey:#"segmentButton4"], listCountOffers], [NSString stringWithFormat:#"%# (%d)", [appSettingsData valueForKey:#"segmentButton5"], [[appDelegate comunication] getSimilarCount:[appDelegate getCurrentCI] idPosition:idPosition idRegion:idRegion]], nil];
segmentControl = [[UISegmentedControl alloc] initWithItems:segmentItems];
segmentControl.frame = CGRectMake(6, 8, 308, 29);
segmentControl.autoresizingMask = UIViewAutoresizingFlexibleWidth;
segmentControl.segmentedControlStyle = UISegmentedControlStyleBar;
[segmentControl setTintColor:[UIColor grayColor]];
[segmentControl addTarget:self action:#selector(segmentedControlIndexChanged:) forControlEvents:UIControlEventValueChanged];
segmentControl.momentary = NO;
segmentControl.selectedSegmentIndex = 0;
});
UIBarButtonItem *toolbarItem = [[UIBarButtonItem alloc] initWithCustomView:segmentControl];
[topToolbar addSubview:toolbarItem.customView];
[customView addSubview:myImageView];
[customView addSubview:topToolbar];
return customView;
}
}
I use "static dispatch_once_t onceToken; dispatch_once(&onceToken, ^{", because I need create this header only first time (because when I scroll table, method is call and call ... and this is wrong) ...
Everything works fine, when I create table view controller it show a headers, when I scroll it, nothing is recreating (it is fine), but when I push back button a then reopen tableview controller headers are empty. Where is problem ? Is there any solution, how to fix it ? Thanks a lot
Well, to me it looks like it's a problem with your static dispatch.
When you push the Back button, chances are that your view holding the table view is released (I don't know your code, but I suppose it is like that), meaning all internal variables are gone - except your static dispatch, which won't be called the next time you instantiate the view. So, during the next instantiation your segmentItems will not be created, but because the view was released, they are empty. You should solve your 'only create once' problem differently, e.g. by remembering the created segmentItems in a dictionary and getting them from there if they do not exist yet.
You're using dispatch_once without really needing to. The block will only be executed once, even if you subsequently remove the view controller from memory and deallocate segmentControl.
Use lazy loading instead - create a property for your segmentControl view within your view controller, and in the accessor for that, if the backing ivar is nil, create it then:
Your synthesize statement:
#synthesize segmentControl = _segmentControl
Your accessor method:
-(UISegmentedControl*)segmentControl
{
if (_segmentControl)
return _segmentControl;
UISegmentedControl *segmentControl = //... create your control here
self.segmentControl = segmentControl
return segmentControl;
}
Then when you want to use the view, use self.segmentControl. The first time you call it, it will be created, the subsequent times, it will be re-used.
check it with breakpoint and see the process. it maybe the memory allocation problem. See this it may help you. http://www.icodeblog.com/2010/12/10/implementing-uitableview-sections-from-an-nsarray-of-nsdictionary-objects/
I am confused regarding auto-complete bubble location while entering data in UITextView.
What i have observed is that depending upon its frame's origin , auto-complete bubble either comes on top or bottom. There is no fixed location, provided scrollEnabled is set to NO.
Here are the two links. Code is written in init()
http://www.flickr.com/photos/26021742#N00/6975525835/
UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(0, 150, 320, 41)] autorelease];
view.backgroundColor = [UIColor grayColor];
[self.view addSubview:view];
UITextView *growingTextView = [[UITextView alloc] initWithFrame:CGRectMake(0, 10, 200, 27)];
growingTextView.font = [UIFont fontWithName:#"Helvetica" size:13];
growingTextView.scrollEnabled = NO;
[view addSubview:growingTextView];
http://www.flickr.com/photos/26021742#N00/6975525727/
UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(0, 50, 320, 41)] autorelease];
view.backgroundColor = [UIColor grayColor];
[self.view addSubview:view];
UITextView *growingTextView = [[UITextView alloc] initWithFrame:CGRectMake(0, 10, 200, 27)];
growingTextView.font = [UIFont fontWithName:#"Helvetica" size:13];
growingTextView.scrollEnabled = NO;
[view addSubview:growingTextView];
Can anyone explain this observed behavior ???
I know that popovers and bubbles will always automatically adjust it's position for ease of use. It's already on Apple's code and in both images the bubble position makes sense.
In the picture below, what type of view is used to create the 'turning on reminders' activity indicator? Is it a custom view with a label and a standard UIActivityIndicator? a built in UIKit class?
As others have said, it is a custom view. Fortunately, a kind third party has created a nice open source implementation:
https://github.com/jdg/MBProgressHUD
yes it is view with a label and a standard UIActivityIndicator.
You don't need a custom view. Something like this completely untested code would do it:
- (UIView *)busyOverlayViewWithText:(NSString *)text {
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(80, 120, 160, 160)];
view.opaque = NO;
view.clipsToBounds = YES;
view.backgroundColor = [UIColor colorWithWhite:0 alpha:.2];
view.layer.cornerRadius = 8;
UIActivityIndicatorView *spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle: UIActivityIndicatorViewStyleWhiteLarge];
spinner.center = CGPointMake(80, 30);
[spinner startAnimating];
[view addSubview:spinner];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 60, 160, 100)];
label.text = text;
label.textColor = UIColor.whiteColor;
label.backgroundColor = UIColor.clearColor;
label.textAlignment = UITextAlignmentCenter;
label.numberOfLines = 0;
label.lineBreakMode = UILineBreakModeWordWrap;
[view addSubview:label];
return view;
}
this is using ARC. Add (auto)releases if you use manual memory management.
This is not a single built-in class. Rather it is a composition of:
A custom transparent view, possibly an image.
A standard activity indicator.
A standard label.
If you want to create something similar then you can easily put them all in a single class.
