[无限互联] IOS开发之瀑布流和下拉刷新上拉加载 效果图： 视图的层次结构 self.view ---AOWaterView(继承UIScrollView)---v1,v2,v3(继承UIView) ---MessView(继承UIView) ---UrlImageButton(继承UIButton，图片作为button的背景图片显示) 类的说明： AOWaterView 继承UIScrollView，能够上下滑动，显示瀑布流。 MessView 继承UIView，图片显示在此视图中。 DataInfo 数据Model类 DataAccess 用于读取plist文件 主要实现代码： 1、读取dataList.plist中的数据，并保存到定义好的Model中，然后把Model存到一个数组中。初始化DataAccess [objc] view plaincopyprint? //初始化 - (void)viewDidLoad { [super viewDidLoad]; //创建DataAccess对象，用来读取dataList.plist中的数据 DataAccess *dataAccess= [[DataAccess alloc]init]; //获取图片Model，加入数组 NSMutableArray *dataArray = [dataAccess getDateArray]; self.aoView = [[AOWaterView alloc]initWithDataArray:dataArray]; self.aoView.delegate=self; [self.view addSubview:self.aoView]; } 读取数据 [objc] view plaincopyprint? -(NSDictionary *)getDicByPlist{ NSString *path=[[NSBundle mainBundle] pathForResource:@dataList ofType:@plist]; NSMutableDictionary *dic = [[NSMutableDictionary alloc]initWithContentsOfFile:path]; return dic; } //获取基础联系列表 -(NSMutableArray *)getDateArray{ NSDictionary *dic = [self getDicByPlist]; NSMutableArray *imageList = [[NSMutableArray alloc]init]; NSMutableArray *dicArray = [dic objectForKey:@imageList]; for (NSDictionary *vdic in dicArray) { DataInfo *data=[[DataInfo alloc]init]; NSNumber *hValue=[vdic objectForKey:@height]; data.height= hValue.floatValue; NSNumber *wValue=[vdic objectForKey:@width]; data.width= wValue.floatValue; data.url = [vdic objectForKey:@url]; data.title=[vdic objectForKey:@title]; data.mess=[vdic objectForKey:@mess]; [imageList addObject:data]; } return imageList; } -(NSDictionary *)getDicByPlist{ NSString *path=[[NSBundle mainBundle] pathForResource:@dataList ofType:@plist]; NSMutableDictionary *dic = [[NSMutableDictionary alloc]initWithContentsOfFile:path]; return dic; } //获取基础联系列表 -(NSMutableArray *)getDateArray{ NSDictionary *dic = [self getDicByPlist]; NSMutableArray *imageList = [[NSMutableArray all
