The values are in the 0.0 to 1.0 range. E.g. divide by 255., but remember the decimal dot so you get floating point division and not integer division. Like selectedColor = [UIColor colorWithRed:14.0/255.0 green:114.0/255.0 blue:199.0/255.0 alpha:1];
Works until iOS11! You can use negative flexible spaces and rightBarButtonItems property instead of rightBarButtonItem: UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil]; spacer.width = -10; // for example shift right bar button to the right self.navigationItem.rightBarButtonItems = @[spacer, yourBarButton];
Set the button type to UIButtonTypeCustom and it’ll stop flashing
In iOS7 there is new button type called UIButtonTypeSystem NS_ENUM_AVAILABLE_IOS(7_0), // standard system button Check your .xib file and change button type to Custom To do this programmatically, add this line to the viewDidLoad: [UIButton buttonWithType:UIButtonTypeSystem];
