这一篇记录的是iOS开发中第三方库WMPageController控件的使用方法，主要是用来分页显示内容的，可以通过手势滑动来切换页面，也可以通过点击标题部分来切换页面，如下图所示：
使用方法:
新建工程DemoTest1，然后通过cocoapods引入WMPageController到项目中，Podfile文件的内容如下：
platform :ios,'7.0' target 'DemoTest1' do pod 'WMPageController', '~> 1.6.4' end
方法一：
（1）创建几个ViewController继承自UIViewController测试用：
（2）打开AppDelegate.m文件，在其中加入下面一个方法：
#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中包含的页面数组
NSArray *controllers = [NSArray arrayWithObjects:[ViewController class], [OneViewController class],[TwoViewController class], nil];
//WMPageController控件的标题数组
NSArray *titles = [NSArray arrayWithObjects:@"体育新闻", @"娱乐新闻",@"直播新闻", nil];
//用上面两个数组初始化WMPageController对象
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)]; // 这里可以设置不同的宽度
//设置WMPageController每个标题的宽度
pageController.menuItemWidth = 375/3;
//设置WMPageController标题栏的高度
pageController.menuHeight = 35;
//设置WMPageController选中的标题的颜色
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）创建个ViewController继承自WMPageController
（2）编辑ViewController.m文件，代码如下：
初始化设置：
#import "TwoViewController.h"
#import "OneViewController.h"
#import "TableViewController.h"
#import "ThreeViewController.h"
@interface ThreeViewController ()
@property (nonatomic, strong) NSArray *titleData;
@end
@implementation ThreeViewController
#pragma mark 标题数组
- (NSArray *)titleData {
if (!_titleData) {
_titleData = @[@"单曲", @"详情", @"歌词",@"歌词"];
}
return _titleData;
}
#pragma mark 初始化代码
- (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 返回子页面的个数
- (NSInteger)numbersOfChildControllersInPageController:(WMPageController *)pageController {
return self.titleData.count;
}
#pragma mark 返回某个index对应的页面
- (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对应的标题
- (NSString *)pageController:(WMPageController *)pageController titleAtIndex:(NSInteger)index {
return self.titleData[index];
}
相关设置：
