本文实例为大家分享了ios实现拼图小游戏的具体代码,供大家参考,具体内容如下
首先找到这8张图片,还需要一张空白的图片,自己随便剪一张吧。
定义三个属性:button可变数组,图片可变数组,正确顺序的图片数组。
@property(retain, nonatomic)nsmutablearray *buttonarray; @property(retain, nonatomic)nsmutablearray *a; @property(retain, nonatomic)nsarray *aa;
铺好拼图界面
//图片数组a,用来储存每个图片名称,并且用于后来的打乱 self.a = [nsmutablearray arraywithobjects:@"1.jpg",@"2.jpg",@"3.jpg",@"4.jpg",@"5.jpg",@"6.jpg",@"7.jpg",@"8.jpg",@"9.jpg", nil]; //备份一个正确顺序的图片数组,用于判断游戏是否过关 self.aa = [nsarray arraywitharray:self.a]; //重新开始按钮 uibutton *star = [[uibutton alloc] initwithframe:cgrectmake(120, 400, 100, 40)]; [star settitle:@"重新开始" forstate:uicontrolstatenormal]; [star settitlecolor:[uicolor bluecolor] forstate:uicontrolstatenormal]; star.layer.cornerradius = 6.6f; star.layer.backgroundcolor = [[uicolor colorwithred:0.922 green:0.925 blue:0.929 alpha:1]cgcolor]; //添加点击事件 [star addtarget:self action:@selector(kaishi) forcontrolevents:uicontroleventtouchupinside]; [self.view addsubview:star]; [star release]; //铺出9个button self.buttonarray = [nsmutablearray array]; nsinteger count = 0; nsinteger wight = 351 / 3; nsinteger higth = 351 / 3; for (int i = 0; i < 3; i++) { for (int j = 0; j < 3; j++) { uibutton *button = [[uibutton alloc] initwithframe:cgrectmake(j * (wight+2) + 10, i * (higth + 2) + 20, wight, higth)]; button.backgroundcolor = [uicolor blackcolor]; //给每个button上图片 [button setimage:[uiimage imagenamed:self.a[count]] forstate:uicontrolstatenormal]; [self.view addsubview:button]; //给每个button添加点击事件 [button addtarget:self action:@selector(change:) forcontrolevents:uicontroleventtouchupinside]; //把button放入数组 [self.buttonarray addobject:button]; button.tag = count; [button release]; count++; } }
实现button的点击事件
- (void)change:(uibutton *)sender{ nsinteger flag = 0; int p = 0; //“9.jpg”是空白的那个,打乱后,得在图片数组里找到所在下标,用flag存在来 for (nsinteger i = 0; i < 9; i++) { if ([self.a[i] isequaltostring:@"9.jpg"]) { flag = i; } } //如果所点击的button的上下左右其中有一个是空白图片的话,就跟空白图片交换在图片数组的位置 if (sender.tag - flag == 3 || sender.tag - flag == -3 || sender.tag - flag == 1 || sender.tag - flag == -1) { [self.a exchangeobjectatindex:flag withobjectatindex:sender.tag]; } //重新给每个button上图片 for (int i = 0; i < 9; i++) { [self.buttonarray[i] setimage:[uiimage imagenamed:self.a[i]] forstate:uicontrolstatenormal]; } //判断是否拼图成功,每对应了一张图片p就加一,如果p最后等于9说明游戏通关 for (int i = 0; i < 9 ; i++) { if ([self.a[i] isequaltostring:self.aa[i]]) { p++; }else{ break; } } if (p == 9) { nslog(@"%d",p); uialertview *a = [[uialertview alloc] initwithtitle:@"恭喜!" message:@"已通关" delegate:self cancelbuttontitle:@"确定" otherbuttontitles:nil]; [a show]; [a release]; } }
打乱所有图片
- (void)kaishi{ //产生0到8两个随机数,通过下标交换图片数组中的两张图片 for (int i = 0; i < 10; i++) { [self.a exchangeobjectatindex:(arc4random() % 9) withobjectatindex:(arc4random() % 9)]; } //给每个button上图片 for (int i = 0; i < 9; i++) { [self.buttonarray[i] setimage:[uiimage imagenamed:self.a[i]] forstate:uicontrolstatenormal]; } }
