3:用法
能够把ViewController里面的tableViewDataSource的三个方法给去掉，然后在载入tableview的时候写上，
NSArray *array=[NSArray arrayWithArray:self.cellInfoArray];
void (^configureCell)(RRFriendViewControllerCell*,RRFriendViewControllerModel *) = ^(RRFriendViewControllerCell* cell,RRFriendViewControllerModel *modelInfo) {
PAImageView *image=[[PAImageView alloc]initWithFrame:cell.myimage.bounds backgroundProgressColor:[UIColor lightGrayColor] progressColor:nil image:nil];
[cell.myimage addSubview:image];
[image setImageURL:modelInfo.image];
cell.mynickName=modelInfo.nickName;
cell.myID=modelInfo.ID;
cell.myrunDistance=modelInfo.rundistance;
cell.mydistance=modelInfo.distance;
};
self.arrayDataSource=[[RRFriendTableViewDataSource alloc]initWithItems:array cellItentifier:@"RRFriendViewControllerCell" configureCellBlock:configureCell];
self.myTableView.dataSource=self.arrayDataSource;
