• 新建关卡控制器


• 自定义UIScrollView


• 增加UIPageView


• 每个关卡的View

整体效果展示

一、新建关卡控制器

1??拖线

－修改控制器class

－修改控制器的View的class（方便设置背景）

－装资源文件

－返回按钮

1??在初始化方法里面做一些事情

－添加四张背景图片

1.创建四个FullView

2.将这四个view加入到scrollview里面（封装成方法）

#pragma mark -加载图片

- (void)loadViews

{

    [self addView:@"select_easy_bg.jpg" index:0];

    [self addView:@"select_normal_bg.jpg" index:1];

    [self addView:@"select_hard_bg.jpg" index:2];

    [self addView:@"select_insane_bg.jpg" index:3];

}

#pragma mark加载图片

- (void)addView:(NSString*)viewName index:(int)index

{

    CGSize size = self.frame.size;

    BgView *bg = [[BgView alloc]initWithFrame:CGRectMake(size.width * index, 0, size.width, size.height)];

    [bg setFullView:viewName];

    [self addSubview:bg];

    [self sendSubviewToBack:bg];

}

－加载关卡信息

#pragma mark - 加载关卡

- (void)loadStages

{

    //1.从plist文件中加载所有的关卡

    NSURL *url = [[NSBundle mainBundle]URLForResource:@"stages" withExtension:@"plist"];

    NSArray *stages = [NSArray arrayWithContentsOfURL:url];

int count = stages.count;

    //2.将关卡中的字典取出，并且转换成一个模型

    for (int i = 0; i < count; i++) {

        NSDictionary *stageDic = stages[i];
//2.1加载关卡的状态

        StageRecordModel *stageRecordModel =[[StageRecordTool sharedStageRecordTool] stageRecordWithNo:i + 1];
//2.2加载关卡的信息

        StageInfo *stageInfo = [StageInfo stageInfoWith:stageDic];

        stageInfo.stageRecordModel = stageRecordModel;

        stageInfo.stageNo = i + 1;
//2.3加载要显示的关卡的View

        Stage *stageView = [[NSBundle mainBundle]loadNibNamed:@"Stage" owner:nil options:nil][0];

        stageView.stageInfo = stageInfo;

        stageView.tag = i + 1;
//2.4为stageView添加手势监听

        [stageView addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(itemClick:)]];
//2.5计算每一个View所在的位置

        CGRect stageFrame = stageView.frame;

        CGFloat stageWidth = self.frame.size.width;

        CGFloat x = (stageWidth * 4 - stageFrame.size.width * 8)/8;

        stageFrame.origin.x = (stageFrame.size.width + x) * (i/3) + 27;

        stageFrame.origin.y = 120 + (i%3)*(stageFrame.size.width + 7);

        stageView.frame = stageFrame;
[self addSubview:stageView];

        [self sendSubviewToBack:stageView];

    }

}

－设置scrollView的contentSize、可滚动、去掉滚动条

//3.设置scrollView的一些属性

        self.contentSize = CGSizeMake(self.frame.size.width * 4, self.frame.size.height);

        self.pagingEnabled = YES;

        self.showsHorizontalScrollIndicator = NO;

1??设置代理，监听是 scrollView的滚动

2??实现代理方法

3??设置pageView的current page

#pragma mark - 给pageView显示当前的页码

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView

{

    _pageView.currentPage = scrollView.contentOffset.x / scrollView.bounds.size.width;

}

1??新建Stage类

2??新建xib

3??新建一个Model和关卡信息一一对应

StageInfo.h

#import <Foundation/Foundation.h>

#import "StageRecordModel.h"

@interface StageInfo : NSObject
@property (nonatomic, copy) NSString *icon;

@property (nonatomic, copy) NSString *title;

@property (nonatomic, copy) NSString *intro;

@property (nonatomic, copy) NSString *format;

@property (nonatomic, copy) NSString *unit;
@property (nonatomic, assign) int stageNo;

@property (nonatomic, assign) double max;

@property (nonatomic, assign) double min;
//让关卡信息拥有一个StageRecordModel属性

@property (nonatomic, strong) StageRecordModel *stageRecordModel;
+ (StageInfo *)stageInfoWith:(NSDictionary*)dict;
@end

StageInfo.m

#import "StageInfo.h"

#define kIcon @"icon"

#define kTitle @"title"

#define kIntro @"intro"

#define kMax @"max"

#define kMin @"min"

#define kFormat @"format"

#define kUnit @"unit"

@implementation StageInfo
+ (StageInfo *)stageInfoWith:(NSDictionary *)dict

{

    StageInfo *stageInfo = [[self alloc]init];
stageInfo.icon = dict[kIcon];

    stageInfo.title = dict[kTitle];

    stageInfo.intro = dict[kIntro];

    stageInfo.format = dict[kFormat];

    stageInfo.unit = dict[kUnit];

    stageInfo.max = [dict[kMax] doubleValue];

    stageInfo.min = [dict[kMin] doubleValue];
return stageInfo;

}
@end

4??加载关卡信息

－Stage类

stage.h

#import <UIKit/UIKit.h>

@class StageInfo;

@interface Stage : UIView
@property (nonatomic, strong) StageInfo *stageInfo;

//关卡数

@property (weak, nonatomic) IBOutlet UIButton *stageNo;

//关卡图标

@property (weak, nonatomic) IBOutlet UIImageView *stageIcon;

//关卡锁

@property (weak, nonatomic) IBOutlet UIView *stageLock;

//关卡覆盖涂层

@property (weak, nonatomic) IBOutlet UIView *stageCover;

//关卡边框

@property (weak, nonatomic) IBOutlet UIImageView *stageRim;

//新关卡

@property (weak, nonatomic) IBOutlet UIImageView *stageNew;

//关卡等级下面的阴影

@property (weak, nonatomic) IBOutlet UIImageView *stageShadow;

//关卡的等级

@property (weak, nonatomic) IBOutlet UIImageView *stageRank;
@end

stage.m

@implementation Stage

+ (id)stageViewWithStageModel:(StageInfo *)stageInfo

{

    Stage *view = [[NSBundle mainBundle] loadNibNamed:@"StageView" owner:nil options:nil][0];

    view.stageInfo = stageInfo;

    return view;

}

#pragma mark 设置关卡信息

- (void)setStageInfo:(StageInfo *)stageInfo

{

    _stageInfo = stageInfo;

    // 1.设置编号

    [_stageNo setTitle:[NSString stringWithFormat:@"%d", stageInfo.no] forState:UIControlStateNormal];

    // 2.设置图标

    _stageImage.image = [UIImage imageNamed:stageInfo.icon];

}

@end

－添加关卡到StageView界面（查看二）
