iOS 导航栏定制

工具分类

extension UINavigationBar {

func initWithViewController(control:UIViewController,title:String) {

control.title=title;

self.barTintColor =
UIColor(rgba:
navigationBarColor);

// 定义导航栏标题栏字体属性

self.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.whiteColor(),
NSFontAttributeName:UIFont.boldSystemFontOfSize(17)];

// 定义导航栏的系统按钮的颜色属性

self.tintColor =
UIColor.whiteColor();

UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent,
animated: false);

}

func initWithLeftAction(control:UIViewController, imgNormal:String, imgHighlighted:String, action:Selector)
{

initWithLeftAction(control, imgNormal: imgNormal, imgHighlighted: imgHighlighted, imgSelected:
"", action: action);

}

func initWithLeftAction(control:UIViewController, imgNormal:String, imgHighlighted:String, imgSelected:String,action:Selector)
{

let leftButton:UIButton =
UIButton(frame: CGRectMake(0,
0, 30,
30));

leftButton.contentEdgeInsets =
UIEdgeInsetsMake(0,
0, 0,
0);

leftButton.setImage(UIImage(named: imgNormal), forState: .Normal);

leftButton.setImage(UIImage(named: imgHighlighted), forState: .Highlighted);

leftButton.setImage(UIImage(named: imgSelected), forState: .Selected);

leftButton.addTarget(control, action: action, forControlEvents: .TouchUpInside);

let leftBarButton:UIBarButtonItem =
UIBarButtonItem(customView: leftButton);

control.navigationItem.leftBarButtonItem = leftBarButton;

}

func initWithRightAction(control:UIViewController, imgNormal:String, imgHighlighted:String, action:Selector)
{

let rightButton:UIButton =
UIButton(frame: CGRectMake(0,
0, 30,
30));

rightButton.contentEdgeInsets =
UIEdgeInsetsMake(0,
0, 0,
0);

rightButton.setImage(UIImage(named: imgNormal), forState: .Normal);

rightButton.setImage(UIImage(named: imgHighlighted), forState: .Highlighted);

rightButton.addTarget(control, action: action, forControlEvents: .TouchUpInside);

let rightBarButton:UIBarButtonItem =
UIBarButtonItem(customView: rightButton);

control.navigationItem.rightBarButtonItem = rightBarButton;

}

}

// 这里要注意的是返回按钮必须在上一级控制器中定制

返回按钮的字体颜色由下一级控制的navigationBar.tingColor决定

extension UINavigationController {

func pushViewController(controller:
UIViewController, animated: Bool, topController:
UIViewController, isCustom:
Bool) {

pushViewController(controller, animated: animated, topController: topController, isCustom: isCustom, title:
"");

}

func pushViewController(controller:
UIViewController, animated: Bool, topController:
UIViewController, isCustom:
Bool, title:String) {

if isCustom ==
false {

pushViewController(controller, animated: animated);

return;

}

var backButtonImage =
UIImage(named: "bt_back")!;

backButtonImage = backButtonImage.resizableImageWithCapInsets(UIEdgeInsetsMake(0, backButtonImage.size.width
- 1, 0,
0));

let backItem =
UIBarButtonItem(title: title, style: .Plain, target:
nil, action: nil);

UIBarButtonItem.appearance().setBackButtonTitlePositionAdjustment(UIOffsetMake(6,
0), forBarMetrics: .Default);

// 设置返回按钮的文字不可见

UIBarButtonItem.appearance().setBackButtonBackgroundImage(backButtonImage, forState: .Normal, barMetrics: .Default);

topController.navigationItem.backBarButtonItem = backItem;

pushViewController(controller, animated: animated);

}
