Can I change the position of navigationbar item?

Question

Here is the snapshot:

And the code is here:

UIButton *leftButton = [UIButton buttonWithType:UIButtonTypeCustom]; leftButton.frame = CGRectMake(0.0f, 0.0f, 46.0f, 32.0f); [leftButton setBackgroundImage:[UIImage imageNamed:@"navi_register_up.png"] forState:UIControlStateNormal]; [leftButton addTarget:self action:@selector(doRegister) forControlEvents:UIControlEventTouchUpInside];  UIBarButtonItem *leftBarItem = [[UIBarButtonItem alloc] initWithCustomView:leftButton]; self.navigationItem.leftBarButtonItem = leftBarItem; [leftBarItem release]; 

Is there any way to move the button up some px? Thank you:)

Answer 1

You need to create a UIBarButtonItem with system item UIBarButtonSystemItemFixedSpace with -5 width which will remove 5 px padding. Then set leftBarButtonItems with both fixed space item and your back bar item like this -

UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil]; [negativeSpacer setWidth:-5];  self.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:negativeSpacer,leftBarItem,nil];
