一、程序实现要求
1.要求
2. 界面分析
(1) 需要读取或修改属性的控件需要设置属性
序号标签
图片
图片描述
左边按钮
右边按钮
(2) 需要监听响应事件的对象,需要添加监听方法

说明:
1> 定义控件属性,注意:属性必须是strong的,示例代码如下:
@property (nonatomic, strong) UIImageView *icon;
2> 在属性的getter方法中实现懒加载,示例代码如下:
1 - (UIImageView *)icon 2 { 3 4 if (!_icon) { 5 6 // 计算位置参数 7 8 CGFloat imageW = 200; 9 10 CGFloat imageX = (320 - imageW) / 2; 11 12 CGFloat imageH = 200; 13 14 CGFloat imageY = 80; 15 16 // 实例化图像视图 17 18 _icon = [[UIImageView alloc] initWithFrame:CGRectMake(imageX, imageY, imageW, imageH)]; 19 20 // 将图像视图添加到主视图 21 22 [self.view addSubview:_icon]; 23 24 } 25 26 return _icon; 27 28 }
四、使用plist文件
(1)使用Plist文件的目的:将数据与代码分离
(2)加载方法:
NSString *path = [[NSBundle mainBundle] pathForResource:@"ImageData" ofType:@"plist"];
_imageList = [NSArray arrayWithContentsOfFile:path];
提示:通常在方法中出现File字眼,通常需要传递文件的全路径作为参数

(4)plist文件
(5)实现效果
五、补充
开发思路:
1.完成基本功能
2.考虑性能
(1)(初始化操作,可以直接调用change进行)
(2)因为要控制序号和图片两个变量,所以考虑使用字典代替掉switch
(3)每次点击,字典都需要创建一次,效率低,可以考虑创建的这部分拿到初始化方法中去,这样就只需要创建一次就ok了。
(4)考虑缺点(对代码的顺序要求极其严格)
(5)懒加载(需要的时候才加载,那么什么时候是需要的时候,及调用get方法的时候)
(6)每次都来一下?效率低 → 只有第一次调用get方法时为空,此时实例化并建立数组,其他时候直接返回成员变量(仅仅执行一次)
注意点:
1.方法的调用堆栈(顺序)。
2.使用plist:让数据的操作更加灵活,把数据弄到外面去,解除耦合性,让耦合性不要太强。实际上是一个xml,是苹果定义的一种特殊格式的xml。
3.bundle-包(只读)
