uibarbuttonitem

问题 I'm trying to set a custom pressed image for my UIBarButtonItem but nothing seems to be working. From my understanding, the code below should work, but despite setting the image for the highlighted state, the button looks exactly the same when pressed. Any ideas? UIImage *barButtonBackground = [[UIImage imageNamed:ANBarButtonItemBackgroundImageName] resizableImageWithCapInsets:UIEdgeInsetsMake(5.0f,5.0f, 5.0f, 5.0f)]; UIImage *barButtonPressedBackground = [[UIImage imageNamed

问题 I have a UIBarButtonItem in my UIToolbar titled Done . Now I want to change the font from the default to "Trebuchet MS" with Bold. How can I do that? 回答1: Because UIBarButtonItem inherits from UIBarItem, you can try - (void)setTitleTextAttributes:(NSDictionary *)attributes forState:(UIControlState)state but this is for iOS5 only. For iOS 3/4, you will have to use a custom view. 回答2: To be precise, this can be done as below [buttonItem setTitleTextAttributes:[NSDictionary

问题 I have tried this approach/hack: http://blog.blackwhale.at/2009/06/uibuttons-in-uinavigationbar/ The problem is this leaves a faint seam. I tried setting the background image of the nested toolbar to an image I captured of what it should be. That didn't work. The image was not applied. I have also tried using a nested UINavigationBar and that didn't seem to work. I have seen this done in several iPhone apps. Does anyone know how? [EDIT] I want the buttons to look like normal UIBarButtonItems

问题 I've created a popover from a UIBarButtonItem using Xcode Storyboards (so there's no code) like this: Presenting the popover works just fine. However, I can't get the popover to disappear when I tap the UIBarButtonItem that made it appear. When the button is pressed (first time) the popover appears. When the button is pressed again (second time) the same popover appears on top of it, so now I have two popovers (or more if I continuer pressing the button). According to the iOS Human Interface

问题 The following code works up through iOS 6: UIButton *myButton = nil; myButton = [UIButton buttonWithType:UIButtonTypeCustom]; myButton.bounds = CGRectMake(0,0,44,30); // setup myButton's images, etc. UIBarButtonItem *item = nil; item = [[UIBarButtonItem alloc] initWithCustomView:customButton]; This is how the button is supposed to be aligned: However, on iOS 7, the button appears to be offset from the right or left by too many pixels: How can I get my custom bar button items to be aligned

问题 Hi friends am new to iphone developing. Am struggle with add badge values on UIBarbutton item on right side. I have tried but i can't solve this problem. Can anyone help me.

问题 I created a toolbar in IB with several buttons. I would like to be able to hide/show one of the buttons depending on the state of the data in the main window. UIBarButtonItem doesn't have a hidden property, and any examples I've found so far for hiding them involve setting nav bar buttons to nil, which I don't think I want to do here because I may need to show the button again (not to mention that, if I connect my button to an IBOutlet, if I set that to nil I'm not sure how I'd get it back).
