下拉过快崩溃

下拉获取数据成功后在移除数组中的元素

[JzZNetworkManager loadDataByString:FootPrintHistory httpHeaderFieldDic:nil parameters:paremeters withType:OTHER_TYPE success:^(id responseObject) {

if ([responseObject[@"statusCode"] integerValue] == 0) {

[self.historyArray removeAllObjects];

NSArray *array = responseObject[@"list"];

if (array.count != 0) {

for (NSDictionary *dic in array) {

MRFootPrint  *model = [[MRFootPrint alloc] initWithDic:dic];

[self.historyArray addObject:model];

}

}

[_tableView.mj_header endRefreshing];

[self.tableView reloadData];
