這一篇記錄的是iOS開發(fā)中第三方庫WMPageController控件的使用方法敌蜂，主要是用來分頁顯示內(nèi)容的箩兽，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紊册，如下圖所示：

使用方法:
新建工程DemoTest1比肄，然后通過cocoapods引入WMPageController到項目中，Podfile文件的內(nèi)容如下：
platform :ios,'7.0'
target 'DemoTest1' do
pod 'WMPageController', '~> 1.6.4'
end
方法一：
（1）創(chuàng)建幾個ViewController繼承自UIViewController測試用：
（2）打開AppDelegate.m文件囊陡，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(shù)組
NSArray *controllers = [NSArray arrayWithObjects:[ViewController class], [OneViewController class],[TwoViewController class], nil];
//WMPageController控件的標題數(shù)組
NSArray *titles = [NSArray arrayWithObjects:@"體育新聞", @"娛樂新聞",@"直播新聞", nil];
//用上面兩個數(shù)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(shè)置不同的寬度
//設(shè)置WMPageController每個標題的寬度
pageController.menuItemWidth = 375/3;
//設(shè)置WMPageController標題欄的高度
pageController.menuHeight = 35;
//設(shè)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(chuàng)建個ViewController繼承自WMPageController
（2）編輯ViewController.m文件芳绩，代碼如下：
初始化設(shè)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(shù)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(shù)
- (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];
}
