Back-like arrow on iOS 7

由 ぃ、小莉子 提交于 2019-12-09 15:08:24
问题 I need to add a left bar button item in my app that looks like system back button, but is not the system back button, since it will appear on view controller that is the only vc of my navController's stack and execute my own code. Simply writing "Back" isn't really good for me, as I need to display the "<" arrow as well. Is there a way to programmatically create an arrow like that, without making image with that arrow? 回答1: Consider using a dummy UIViewController as a root view controller for

iOS 5 Back Button Size

由 耗尽温柔 提交于 2019-12-09 13:50:07
问题 I'm using the iOS 5 UIAppearance protocol to use a custom navigation bar back button as seen here. Unlike other methods I've found, this one is the best since it preserves the default back button animations and behaviours. The only problem is that I can't change its size or set it to not clip subviews . Here's what's happening: A is intended behaviour, B is default style, C is the clipped result. Unfortunately, it's not as easy as setting UIBarButtonItem to clipsToBounds=NO. Does anyone know

问题 I want to change the color of my right bar button item from black to white. It is a button as a search icon. I have not coded the search implementation yet as I want to get the main interface completed first. I thought that I'd written the correct codes so it should appear as white, but it seems to still appear as black in both the storyboard and simulator. In the storyboard, I have also set it to white. Here is my code, which is located in the AppDelegate.swift file: func application

由 好久不见. 提交于 2019-12-06 12:04:42
问题 I can't seem to get a UISearchBar to position itself from the far left to the far right in the navigation bar. In the -(void)viewDidLoad method, I have the following code: UISearchBar *sb = [[UISearchBar alloc] initWithFrame:self.tableView.tableHeaderView.frame]; sb.delegate = self; self.navigationItem.titleView = sb; [sb sizeToFit]; [sb release]; When you build and run, it looks just fine at first glance. However, looking more closely, you can tell there is a margin/space on the left. This

How to remove UINavigatonItem's border line

由 故事扮演 提交于 2019-12-06 05:42:13
问题 Is it possible to remove UINavigationItem's border? My view under black nav. bar is black and i don't want no visual border between them. To make it clearer (image is not from my app): 回答1: You can't hide it. You can add a subview that will mask it. Example: UIView *overlayView = [[UIView alloc] initWithFrame:CGRectMake(0, 43, 320, 1)]; [overlayView setBackgroundColor:[UIColor whiteColor]]; [navBar addSubview:overlayView]; // navBar is your UINavigationBar instance [overlayView release]; I
