iOS開發--新聞首頁效果WMPageController的使用

TatBaron 8年前發布 | 10K 次閱讀 iOS開發 移動開發

這一篇記錄的是iOS開發中第三方庫WMPageController控件的使用方法,主要是用來分頁顯示內容的,可以通過手勢滑動來切換頁面,也可以通過點擊標題部分來切換頁面,如下圖所示:

使用方法:

新建工程DemoTest1,然后通過cocoapods引入WMPageController到項目中,Podfile文件的內容如下:

platform :ios,'7.0'

target 'DemoTest1' do

 pod 'WMPageController', '~> 1.6.4'

end

方法一:

(1)創建幾個ViewController繼承自UIViewController測試用:

(2)打開AppDelegate.m文件,在其中加入下面一個方法:

#import "WMPageController.h"

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

@interface AppDelegate ()

@property(nonatomic,strong) WMPageController *createPages;

@end

@implementation AppDelegate

- (WMPageController *)createPages {


    //WMPageController中包含的頁面數組
    NSArray *controllers = [NSArray arrayWithObjects:[ViewController class], [OneViewController class],[TwoViewController class], nil];
    //WMPageController控件的標題數組
    NSArray *titles = [NSArray arrayWithObjects:@"體育新聞", @"娛樂新聞",@"直播新聞", nil];
    //用上面兩個數組初始化WMPageController對象
    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)]; // 這里可以設置不同的寬度

    //設置WMPageController每個標題的寬度
    pageController.menuItemWidth = 375/3;
    //設置WMPageController標題欄的高度
    pageController.menuHeight = 35;
    //設置WMPageController選中的標題的顏色
    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;
}

方法二:

(1)創建個ViewController繼承自WMPageController

(2)編輯ViewController.m文件,代碼如下:

初始化設置:

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

#import "ThreeViewController.h"

@interface ThreeViewController () 

@property (nonatomic, strong) NSArray *titleData;
@end

@implementation ThreeViewController

#pragma mark 標題數組
- (NSArray *)titleData {
    if (!_titleData) {
        _titleData = @[@"單曲", @"詳情", @"歌詞",@"歌詞"];
    }
    return _titleData;
}
#pragma mark 初始化代碼
- (instancetype)init {
    if (self = [super init]) {


        self.titleSizeNormal = 15;
        self.titleSizeSelected = 15;
        self.menuViewStyle = WMMenuViewStyleLine;
        self.menuItemWidth = [UIScreen mainScreen].bounds.size.width / self.titleData.count;
        self.menuHeight = 50;
    }
    return self;
}

WMPageController --Datasource & Delegate

#pragma mark - Datasource & Delegate

#pragma mark 返回子頁面的個數
- (NSInteger)numbersOfChildControllersInPageController:(WMPageController *)pageController {
    return self.titleData.count;
}

#pragma mark 返回某個index對應的頁面
- (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 返回index對應的標題
- (NSString *)pageController:(WMPageController *)pageController titleAtIndex:(NSInteger)index {

    return self.titleData[index];
}
