IOS Development--imitation news home effect Wmpagecontroller The use of detailed _ios

This record is the use of the third party library Wmpagecontroller control in iOS development, mainly used to page content, you can move through gestures to switch pages, or by clicking on the title section to switch pages, as shown in the following image:

How to use:

Create a new project DemoTest1 and then introduce Wmpagecontroller to the project via Cocoapods, podfile the contents of the file are as follows:

Platform:ios, ' 7.0 '

target ' DemoTest1 ' do

 pod ' wmpagecontroller ', ' ~> 1.6.4 '

end

Method One:

(1) Create several Viewcontroller inherits from Uiviewcontroller test:

(2) Open the APPDELEGATE.M file and add one of the following methods to it:

#import "WMPageController.h"

#import "OneViewController.h"
#import "ViewController.h"
#import "TwoViewController.h"

@interface AppDelegate ()

@property (nonatomic, strong) WMPageController * createPages;

@end

@implementation AppDelegate

-(WMPageController *) createPages {


  // Array of pages contained in WMPageController
  NSArray * controllers = [NSArray arrayWithObjects: [ViewController class], [OneViewController class], [TwoViewController class], nil];
  // WMPageController title array
  NSArray * titles = [NSArray arrayWithObjects: @ "体育 新闻", @ "娱乐 新闻", @ "直播 新闻", nil];
  // Initialize the WMPageController object with the above two arrays
  WMPageController * pageController = [[WMPageController alloc] initWithViewControllerClasses: controllers andTheirTitles: titles];
  pageController.menuViewStyle = WMMenuViewStyleLine;
  pageController.titleColorSelected = [UIColor whiteColor];
  pageController.titleColorNormal = [UIColor colorWithRed: 168.0 / 255.0 green: 20.0 / 255.0 blue: 4 / 255.0 alpha: 1];
  pageController.progressColor = [UIColor colorWithRed: 168.0 / 255.0 green: 20.0 / 255.0 blue: 4 / 255.0 alpha: 1];
  // pageController.itemsWidths = @ [@ (70), @ (100), @ (70)]; // You can set different widths here

  // Set the width of each title of WMPageController
  pageController.menuItemWidth = 375/3;
  // Set the height of the WMPageController title bar
  pageController.menuHeight = 35;
  // Set the color of the title selected by WMPageController
  pageController.titleColorSelected = [UIColor colorWithRed: 200 green: 0 blue: 0 alpha: 1];
  return pageController;
}


-(BOOL) application: (UIApplication *) application didFinishLaunchingWithOptions: (NSDictionary *) launchOptions {


 self.window = [[UIWindow alloc] initWithFrame: [UIScreen mainScreen] .bounds];


  WMPageController * page = [self createPages];

  UINavigationController * na = [[UINavigationController alloc] initWithRootViewController: page];

  self.window.rootViewController = na;

  [self.window makeKeyAndVisible];

  return YES;
}

Method Two:

(1) Create a viewcontroller inherit from Wmpagecontroller

(2) Edit the viewcontroller.m file with the following code:

Initialization settings:

#import "TwoViewController.h"
#import "OneViewController.h"
#import "TableViewController.h"

#import " ThreeViewController.h "

@interface threeviewcontroller () 

@property (nonatomic, strong) Nsarray *titledata;
@end

@implementation threeviewcontroller

#pragma mark title array
-(Nsarray *) Titledata {
  if (!_titledata) {
    _titledata = @[@ "single", @ "Details", @ "lyrics", @ "lyrics"];
  }
  return _titledata;
}
#pragma mark initialization Code
-(instancetype) init {
  if (self = [super init]) {


    self.titlesizenormal =;
    self.titlesizeselected =;
    Self.menuviewstyle = Wmmenuviewstyleline;
    Self.menuitemwidth = [UIScreen mainscreen].bounds.size.width/self.titledata.count;
    Self.menuheight = M
  return self;
}

Wmpagecontroller--datasource & Delegate

#pragma mark-Datasource & Delegate

#pragma mark Returns the number of child pages
-(NSInteger) numbersOfChildControllersInPageController: (WMPageController *) pageController {
  return self.titleData.count;
}

#pragma mark Returns the page corresponding to an index
-(UIViewController *) pageController: (WMPageController *) pageController viewControllerAtIndex: (NSInteger) index {


  switch (index) {
      case 0: {

        TwoViewController * vcClass = [[TwoViewController alloc] init];
        vcClass.title = @ "1";

        return vcClass;
      }

        break;
      case 1: {

        OneViewController * vcClass = [OneViewController new];
        vcClass.title = @ "2";
        return vcClass;

      }
        break;
      case 2: {

        TableViewController * vcClass = [TableViewController new];
        vcClass.title = @ "3";
        return vcClass;

      }
        break;

      default: {

        OneViewController * vcClass = [OneViewController new];
        vcClass.title = @ "4";
        return vcClass;

      }

        break;
    }


}

#pragma mark Returns the title corresponding to index
-(NSString *) pageController: (WMPageController *) pageController titleAtIndex: (NSInteger) index {

  return self.titleData [index];
}
