申请数据有两个共同点

解析的类型的方法一样

url page++

把数据解析的部分取出来

把数据的总数组返回

刷新和加载对数组的处理在这里内部完成

用url 和 page array 记录数据

- (instancetype)initWithScrollView:(UIScrollView *)scrollView

url:(NSString *)url

style:(NSArray *(^)(id result))style

refresh:(void(^)(NSArray *array))refresh

empty:(Team9EmptyTool *)empty

{

self = [super init];

if (self) {

self.orignUrl = url;

refresh([NSArray array]);

[scrollView.footer resetNoMoreData];

void(^block)() = ^{

scrollView.footer = [MJRefreshAutoNormalFooter footerWithRefreshingBlock:^{

NSRange range = [self.url rangeOfString:[NSString stringWithFormat:@"page=%ld",self.page]];

if (!range.length) {

[scrollView.footer endRefreshingWithNoMoreData];

return;

}

self.url = [self.url stringByReplacingCharactersInRange:range withString:[NSString stringWithFormat:@"page=%ld",self.page + 1]];

[JQAFNetworkTool getUrl:self.url success:^(id result) {

NSArray *array = style(result);

if (array.count) {

[self.array addObjectsFromArray:array];

array = [NSArray arrayWithArray:self.array];

refresh(array);

// completion(array);

self.page++;

[scrollView.footer endRefreshing];

} else {

[scrollView.footer endRefreshingWithNoMoreData];

}

}failure:^(NSError *error) {

[scrollView.header endRefreshing];

}];

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

[scrollView.footer endRefreshing];

});

}];

};

[JQAFNetworkTool getUrl:self.orignUrl success:^(id result) {

NSArray *array = style(result);

self.array = array.mutableCopy;

refresh(array);

block();

}];

scrollView.header = [MJRefreshNormalHeader headerWithRefreshingBlock:^{

empty.loading = YES;

[scrollView.footer resetNoMoreData];

[JQAFNetworkTool getUrl:self.orignUrl success:^(id result) {

NSArray *array = style(result);

self.array = array.mutableCopy;

refresh(array);

self.page = 1;

self.url = self.orignUrl;

[scrollView.header endRefreshing];

block();

} failure:^(NSError *error) {

[scrollView.header endRefreshing];

}];

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

[scrollView.header endRefreshing];

});

}];

}

return self;

}

+ (Team9RefreshTool *)toolWithScrollView:(UIScrollView *)scrollView

url:(NSString *)url

}

- (void)setOrignUrl:(NSString *)orignUrl

{

if (_orignUrl != orignUrl) {

_orignUrl = orignUrl;

}

self.page = 1;

self.url = self.orignUrl;

}
