Ios开发知识点小结

关于MVC分层设计: 

MVC分层将逻辑和界面控件分开, 控件对应相关的函数来响应操作.

在ios开发中, 最简单最快的就是利用视图控制(.xib）来完成界面，控件等非逻辑处理。

让然，也可以手动分层，全用代码控制。 由于我第一次接触MVC模式开发，开始不太习惯，所以在项目中还是用的老方法，要什么就写什么。

六角跳棋中，底层为棋盘：

chessBoardImg = [UIImageimageNamed:@"紫高亮.jpg"];   // UIImage  设置图片，将贴在底层容器中哦给你无

chessBoardViewImg = [[UIImageViewalloc]initWithImage:chessBoardImg]; //UIImageView 一个视图， 并贴上图片。

[chessBoardViewImgsetFrame:CGRectMake(0, 0, 320, 480)]; //给视图设置显示窗口

[selfinsertSubview:chessBoardViewImgatIndex: 0];       //将图片置于底层

棋盘图片放置在底层。 棋子为button，贴在棋盘上面, 每个棋子都有对应的相应函数：

[redChessBt addTarget:selfaction:@selector(redChessSelect:)forControlEvents:UIControlEventTouchUpInside];

点击redChessBt即红色按钮时，将对选中的红色按钮执行 redChessSelect操作. 

选中棋子后, 将计算改棋子在棋盘中可走的位置,并点亮可走区作提示. 这里用到棋盘遍历搜索.

如果是电脑走棋,则遍历该色10个棋子, 选取一个最佳走棋位置走棋.

主棋盘下放贴另一个菜单视图, 包括返回, 重新开始, 帮助等.  

// 放置浮动菜单

CGRect menuRect;

menuRect =CGRectMake(0, 435, 320, 80);

menuView = [[UIViewalloc]initWithFrame:menuRect];    // 增加一个UIView 视图

menuViewImg = [[UIImageViewalloc]initWithImage:[UIImageimageNamed:@"菜单.png"]];

[menuViewImgsetFrame:CGRectMake(0, 0, 320, 80)];

[menuViewaddSubview:menuViewImg];// 图片填充视图

//初始化重新开始，返回， 帮助，菜单四个按钮。

clearBoard = [[UIButtonalloc]initWithFrame:CGRectMake(115, 45, 90, 35)];

[clearBoardsetImage:restartImgforState:UIControlStateNormal];      //原始图片效果

[clearBoardsetImage:restartImg1forState:UIControlStateHighlighted]; //点击后图片的效果。

[clearBoardaddTarget:selfaction:@selector(restartGame:)forControlEvents:UIControlEventTouchUpInside];

[menuViewaddSubview:clearBoard];     // clearBoard按钮属于menuView 视图

backHome = [[UIButtonalloc]initWithFrame:CGRectMake(12, 45, 60, 35)];

[backHomesetImage:backImgforState:UIControlStateNormal];

[backHomesetImage:backImg1forState:UIControlStateHighlighted];

[backHomeaddTarget:selfaction:@selector(backHome:)forControlEvents:UIControlEventTouchUpInside];

[menuViewaddSubview:backHome];

helpBt = [[UIButtonalloc]initWithFrame:CGRectMake(250, 45, 60, 35)];

[helpBtsetImage:helpImgforState:UIControlStateNormal];

[helpBtsetImage:helpImg1forState:UIControlStateHighlighted];

[helpBtaddTarget:selfaction:@selector(helpView:)forControlEvents:UIControlEventTouchUpInside];

[menuViewaddSubview:helpBt];

Menu = [[UIButtonalloc]initWithFrame:CGRectMake(12, 20, 60, 30)];

[MenuaddTarget:selfaction:@selector(showMenu:)forControlEvents:UIControlEventTouchUpInside];

[menuViewaddSubview:Menu];

[selfaddSubview:menuView]; 

[selfbringSubviewToFront:menuView];

//从allChess字典中找到关键位置为ap的坐标，并加入allChessTemp临时存放的字典（语法）

CGPoint app =CGPointFromString([allChessobjectForKey:[NSNumbernumberWithInt:ap]]);

[allChessTempsetObject:NSStringFromCGPoint(app)forKey:[NSNumbernumberWithInt:ap]]; 

// 落子点选择  点击棋盘放大的操作

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {

if (ifTwoTimeChessBoard ==NO){

CGPoint endTouch;

UITouch *touch = [touchesanyObject];

endTouch = [touchlocationInView:self]; // 只需获取最后的touch坐

chessX = endTouch.x;// 在小棋盘上的x坐标

chessY = endTouch.y;// 在小棋盘上的y坐标

[selfzoomIn]; //棋盘放大

}else{

[selfzoomOut]; //棋盘缩小

//    ********    控制点击边界位置时候, 放大棋盘显示棋盘不应该越界   *************
