问题 I am doing project of bill. there are many bills that i can scroll and each bill have many items with quantity and price. At the button, there are also many buttons on toolbar. Total Price of bill is 1 button among them, and i don't know how to show the number of total price on this button ! 回答1: A UIButton has a currentTitle-property and you should be able to get the title from that. A UIBarButtonItem has a possibleTitles-property which is an NSSet containing all possible titles the bar

问题 I stumbled upon this SO discussion on adding/removing qlpreviewcontroller's uibarbuttonitems. However they were removing the navigation bar and overlaying a new one on top of it. I was looking to change the toolbar primarily because the toolbar that comes with QLPreviewController is black and the rest of the toolbars in my application are white. I have code in place to get the bar overlaying but it seems that when I set the toolbar tint color to white, its actually becoming a light gray. I

问题 Hoping someone here has conquered this one 'cuz it's driving me crazy. My app includes a popover that is used to enter and edit information. I learned today that it's possible to show a toolbar at the bottom of the popover and that's great -- except that I cannot for the life of me get any buttons to show on said toolbar. Here's where we start: UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController: editorViewer]; //*** This makes the toolbar

问题 I need to work with a subclassed UIToolbar in the UINavigationController . I know this can be done via Interface Builder but I need it to be done programatically. The docs state that the UINavigationController toolbar property is readonly so I'm at a bit of a loss as to how I proceed.

问题 As can be seen below, my toolbar gets chopped off in the compact size: My UI consists of a ToolBar and a WebView. The constraints I tried don't work, although I did get them to turn blue. As you can see, my toolbar is pinned to the top, the left side, and the right side (I also set a constant height). How can I get my toolbar to display correctly in the compact size. Thanks. Edit1: Edit2: Here is what I did to get things to display correctly: I had to drag the edges of the WebView all the way

问题 This question already has an answer here : Creating nib view from UIBarButtonItem? (1 answer) Closed 5 years ago . So I've seen previous questions similar to this but they were of no help. I've read Apple's documentation too but I could not understand where I've gone wrong. AFAIK I did everything logically, but when I click on my done button on an UItoolbar overlay, the button can be pushed but it does not do anything. This obviously means it fails to acknowledge the written code. But how? I

问题 I have set tintcolor for my UIToolBar.It displays Correctly in ios 6.0 but it shows black color on ios 5.0 simulator. My code is here originalBounds = mysearchBarBarItem.customView.bounds; mySearchBar.bounds = CGRectMake(0,0,215,44); myTopToolbar.tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:NAVIGATION_BAR_BACKGROUND]]; myTopToolbar.barStyle = UIBarStyleDefault; mySearchBar.barStyle = UIBarStyleDefault; mySearchBar.tintColor = [UIColor colorWithPatternImage:[UIImage

问题 I have a UIViewController. I want to add a UIToolbar to the bottom, but IB is not letting me. How can I achieve this? Note: The UIViewController is part of a UINavigationController. I'm not sure if this affects the visibility of the toolbar. 回答1: Starting from iOS 3.0 you can set toolbar items you want using following UIViewController 's method: - (void)setToolbarItems:(NSArray *)toolbarItems animated:(BOOL)animated of simply set or override toolbarItems property. And toolbar will appear
