Customize the navigation bar: Background color settings, button caption picture settings, picture coordinate modification

First, modify the system native navigation bar to modify the navigation bar background color

Self.navigationController.navigationBar.barTintColor = [Uicolor colorwithhexstring:@ "#2295f2 "];

Custom navigation bar Buttons

Self.navigationItem.rightBarButtonItem = [[Uibarbuttonitem alloc]initwithimage:[uiimage imagenamed:@ "  Btn-menu-h"] style:uibarbuttonitemstyleplain target:self action: @selector (Menubtnclick)];

The custom button picture is too far from the edge of the screen and can be modified by the following code

Modified Rightbarbuttonitem margin

system default Rightbarbuttonitem margin

Self.navigationItem.leftBarButtonItem.imageInsets = Uiedgeinsetsmake (0,-0,0 = Uiedgeinsetsmake (0,-ten,0,ten); 

Setting the background color of the navigation bar will cause the button title color to change, modify the following method

Self.navigationController.navigationBar.tintColor = [Uicolor Whitecolor];

Modify title color and font size

self.navigationController.navigationBar.titleTextAttributes [email Protected]{nsforegroundcolorattributename: [ Uicolor colorwithhexstring:@ "#ffffff"],nsfontattributename:[uifont systemfontofsize: []};

Modify button title Color size

[Self.navigationItem.rightBarButtonItem settitletextattributes:@{nsforegroundcolorattributename: [Uicolor Colorwithhexstring:@ "#ffffff"],nsfontattributename:navitermfont} forstate: UIControlStateNormal];

Because the navigation bar is translucent, if you do not handle the color of the navigation bar and the design color is always error this line of code can turn off the translucent effect, but will cause the coordinates 0 points to move.

[Uinavigationbar appearance].translucent = NO;

Turn off coordinates 0 point move

Self.edgesforextendedlayout = Uirectedgenone;

For more information about the Translucent property, please visit: IOS7 navigation bar Adaptation to the--translucent property setting. Custom navigation bars If the system navigation bar does not meet the design requirements, it needs to be customized according to the design, only the title and left and right buttons are written in the code. You can add any control according to your design.
