How to properly position the back button in iOS7
ios7, objective-c, uinavigationbar, uinavigationitem
Solution
EDIT I think I might have found the trick (in iOS 7 Design Resource -- UIKit User Interface Catalog.) Under Bar Button Items
Note that a bar button image will be automatically rendered as a template image within a navigation bar, unless you explicitly set its rendering mode to UIImageRenderingModeAlwaysOriginal. For more information, see Template Images.
Under Template Images they have some code to specify the UIImageRenderingMode.
UIImage *myImage = [UIImage imageNamed:@"back"];
UIImage *backButtonImage = [myImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
// now use the new backButtomImage
[[UINavigationBar appearance] setBackIndicatorImage:backButtonImage];
[[UINavigationBar appearance] setBackIndicatorTransitionMaskImage:backButtonImage];
Try creating the UIImage with alignment insets and then set the Back Indicator image.
UIEdgeInsets insets = UIEdgeInsetsMake(10, 0, 0, 0); // or (0, 0, -10.0, 0)
UIImage *alignedImage = [[UIImage imageNamed:@"back"] imageWithAlignmentRectInsets:insets];
[[UINavigationBar appearance] setBackIndicatorImage:alignedImage];
[[UINavigationBar appearance] setBackIndicatorTransitionMaskImage:alignedImage];
You might also try adjusting the position of the UINavigationBar title text
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:(CGFloat)adjustment forBarMetrics:(UIBarMetrics)barMetrics];
Problem
I used this code to use a custom image as the back button in the whole app. ``` [[UINavigationBar appearance] setBackIndicatorImage:[UIImage imageNamed:@"back"]]; [[UINavigationBar appearance] setBackIndicatorTransitionMaskImage:[UIImage imageNamed:@"back"]]; ``` The image dimensions are 30 x 30. The code adds the image as the back button but the position is not the correct, as you can see in the following image: Any ideas on how to properly position the image without modifying its dimensions (at least the visual part of the image (circle + arrow))? EDIT: I don't want to use a custom back button because that forces me to disable the swipe/back-gesture in iOS7
