I wrote the following code to make my toolbar transparent. [mtoolbar setBackgroundColor:[UIColor clearColor]]; How do I make UIToolbar transparent? Luke You can set the property translucent to YES and see if this helps. [self.toolbar setBackgroundImage:[UIImage new] forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault]; [self.toolbar setBackgroundColor:[UIColor clearColor]]; Setting the property translucent to YES will not work in iOS 5 and below. Here's how it can be done without subclassing toolbar: const float colorMask[6] = {222, 255, 222, 255, 222, 255}; UIImage *img = [

What works to pass touches through to (and display all) subviews?

问题 I have the following subview chain: UIViewController.view -+ |-> UIView (subclass) -+ | +-> UIToolbar | +------------------------> UIWebView In the subclass, I override its -touchesEnded:forEvent: method in order to hide and show the UIToolbar on a single tap touch, through a CAAnimation , as well as issue an NSNotification that causes the view controller to hide its navigation bar. If I do not add the UIWebView as a subview to the view controller's view, then this works properly. If I then

Can I center a UIToolbar item?

I am putting a label on a UIToolbar (per this tip: Adding a UILabel to a UIToolbar ). But the toolbar has a button on the left side, and so flexible spaces throw the label off the center, which is where I'd like it to be. Can I somehow center this toolbar item so that it remains centered in the toolbar? (Already tried balancing the button with a dummy fixed space, no dice.) Thanks! Simplest way would be to put the label above the bar, in it's parent view, and justify it there. Add a flexible space item to the left and right of your center item, like you did. Then add a fixed space item at the

问题 I have a UIToolbar that has a white tint, with a bar button item, followed by some flexible space, followed by another bar button item. I would like to make the toolbar completely clear so that I can see what is under the flexible space (I don't care about seeing what is behind the buttons). Is there a way to do this? I have tried setting the toolbar to translucent, but that does not make it completely clear. 回答1: [self.toolbar setBackgroundImage:[UIImage new] forToolbarPosition

问题 I'm using a storyboard and I've a split view where the master is a UITableViewController. Like the iPad Mail app, I'd like to display a UIToolbar. I wasn't able to add the toolbar via storyboard but I managed to add it programmatically. I'm also able to add a UILabel to the toolbar, but I can't find a way to add a refresh button or any kind of UIBarButtonItem. Any idea? - (void)viewDidLoad { [super viewDidLoad]; [self.navigationController setToolbarHidden:NO]; UILabel *label = [[UILabel alloc

Hiding a UINavigationController's UIToolbar during viewWillDisappear:

不问归期 提交于 2019-12-03 08:16:31
问题 I've got an iPhone application with a UITableView menu. When a row in the table is selected, the appropriate view controller is pushed onto the application's UINavigationController stack. My issue is that the MenuViewController does not need a toolbar, but the UIViewControllers which are pushed onto the stack do. Each UIViewController that gets pushed calls setToolbarHidden:animated: in viewDidAppear: . To hide the toolbar, I call setToolbarHidden:animated: in viewWillDisappear: . Showing the

This should work: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [navigationBar setAlpha:0.0]; [UIView

UIToolbar height on device rotation

好久不见. 提交于 2019-12-03 06:01:22
问题 From the iOS Human Interface Guidelines, iOS UI Element Usage Guidelines On iPhone, take into account the automatic change in toolbar height that occurs on device rotation . In particular, make sure your custom toolbar icons fit well in the thinner bar that appears in landscape orientation. Don’t specify the height of a toolbar programmatically. I can see the height changing from 44 points to 32 points in Mail , Twitter for iPhone and Dropbox for example, but when I add a toolbar (with

UIToolbar setBackgroundColor doesn't fully change color

廉价感情. 提交于 2019-12-03 05:29:00
问题 I'm trying to set the background color of a UIToolBar . I tried selecting the color from IB's Attribute Inspector, and tried setting it programmatically through setBackgroundColor:[UIColor ...] . Both solutions work, but only partially: the color blends something like 50% with white and the toolbar is very light...doesn't show the color I actually chose, but a much lighter version of it. How can I have the UIToolBar of the actual color I'm choosing? It's probably very simple to solve, but I
