MobileOA第一期总结
前段时间一直没有更新博客，好想给自己找个借口———恩，我还是多找几个吧。毕业论文、毕业照，再感伤一下，出去玩一下，不知不觉就过去几个月了。然后上个月底才重新回到学习之路，从此让我走上正轨吧。
这算是本宝宝人生中的第一个项目了，虽然分给我的两个模块都很基础，但在编写过程中，仍然出现很多问题。从编码习惯到后期的数据处理，总结一下，以后谨记。一、问题
1、注释
这次项目过后，我才真正切身感受到注释的重要性———这次的项目有些大，一个师姐带着我编写。注释没写好，会让跟你合作的人平添各种麻烦，就连本人，到了后期，UI界面调整之后，又回过头找当初的初衷是在干嘛，浪费时间。
2、工作流逻辑
这次的OA项目，我一共写过三个模块——请假工作流，任务模块，会议模块
由于最初写的请假工作流，并没有什么太大的逻辑问题，与其他模块没有太大的关联，我只拘泥在自己的小世界里写自己的东西，结束后集成进去便无大碍。以至于，我在接到任务和工作流模块之后，也只是安心做自己的，到后来发现，这中间涉及到的方方面面，竟然与其他模块有着千丝万缕的联系，我从一开始的工作流走向与数据来源都没弄清楚，以至于在后面调接口的时候，牵扯进很多问题，甚至连UI都改了不少。
PS：可能是因为我们实验室没有专门的UI设计师，，，但至少，在以后两年的时间里，我懂得了，不要全信设计师，被坑得到最后都满脸懵逼。
3、数据渲染
由于这是第一次参与一个完整的项目，一开始便只顾着写死数据，把页面重现以为就OK了，却没有想到零零散散的数据会给后期的数据处理造成多大的麻烦，傻乎乎的甚至有些需要从后台获取的数据不知道在@interface里面声明。
4、接口调试
我的时间，大部分还是浪费在了调接口上，可能是因为我从一开始就对接口有一种莫名的恐惧感。一遇到问题，就开始怀疑自己的能力。
其次，在接口调试过程中，要学会调试，单步跟踪，清楚代码的走向，数据获取在哪一步出现了问题，到底是自己的参数问题还是后台接口的问题，不到万不得已也别怀疑接口，宝宝在被打脸n次后吸取了教训，再也不敢随便找接口的麻烦了。还好是在学校，这要是到了公司，估计再也没人愿意写我的接口了 - -
5、数据处理
刚刚开始的时候，我总是在子进程中处理数据，只拿出自己需要的字段。然而，UI只要出现一些小的变动，就得重新分析获取数据，徒增各种麻烦。
二、可重用代码
以下是我在编写过程中用到的师姐的代码，先备份一下，有时间看看。1、后台获取数据接口
（1）可刷新（分页）
- (void)setupRefresh
{
self.tableView.mj_header = [MJRefreshNormalHeader headerWithRefreshingTarget:self refreshingAction:@selector(headerRereshing)];
[self.tableView.mj_header beginRefreshing];
self.tableView.mj_footer = [MJRefreshAutoNormalFooter footerWithRefreshingTarget:self refreshingAction:@selector(footerRereshing)];
}
#pragma mark 开始进入刷新状态
- (void)headerRereshing
{
[self loadTaskList:YES];
}
- (void)footerRereshing
{
[self loadTaskList:NO];
}
#pragma mark -- 获取任务数据
- (void)loadTaskList:(BOOL)isReFresh{
if (isReFresh) {
_pageNum = 1;
}
NSString *urlStr = [NSString stringWithFormat:@"%@%@",BASE_URL,TaskList_URL];
NSDictionary *jsonParam = @{
@"telephone" : [NSUserDefaults getUserTelephone ],
@"page" : @(_pageNum),
@"pageSize" : @(10)
};
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
dispatch_queue_t myQueue = dispatch_queue_create([@"loadTaskList" UTF8String], NULL);
dispatch_async(myQueue, ^{
//请求数据
NSData *data = [WebGetDataUtil getDataByURL:[NSURL URLWithString:urlStr ] withJsonParam:jsonParam];
NSError *error;
if (data) {
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:&error ];
NSInteger code = [[dic objectForKey:@"code"]integerValue];
if (code == 1) {
//判断服务器是否返回数据
NSError *error;
NSArray *array = [dic objectForKey:@"data"];
if(array){
//判断返回的数据是否正确解析
dispatch_async(dispatch_get_main_queue(), ^{
//前台更新ui
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSDictionary * news = nil;
NSDictionary * news1 = nil;
if (self.taskData.count >0 && array.count >0) {
news = [self.taskData objectAtIndex:(self.taskData.count - 1)];
news1 = [array objectAtIndex:array.count-1];
}
if (array.count != 0 ) {
BOOL addFlag = YES;
if (news && !isReFresh) {
//上拉加载的是后台给出的是重复数据
if ([news[@"id"]integerValue] == [news1[@"id"]integerValue]) {
addFlag = NO;
[KSToastView ks_showToast:@"已经是最后一条" duration:3.0f];
}
}
if (isReFresh) {
[self.taskData removeAllObjects];
}
if (addFlag) {
[self.taskData addObjectsFromArray:array];
}
[_tableView reloadData];
_pageNum ++;
}else{
//没有新的数据
if(!isReFresh){
[KSToastView ks_showToast:@"已经是最后一条" duration:3.0f];
}
}
if(isReFresh) {
[self.tableView.mj_header endRefreshing];
}
else {
[self.tableView.mj_footer endRefreshing];
}
});
}
else{
//数据解析有误
dispatch_async(dispatch_get_main_queue(), ^{
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSLog(@"error:%@",error);
if(isReFresh)
[self.tableView.mj_header endRefreshing ];
else [self.tableView.mj_footer endRefreshing ];
});
}
}else {
dispatch_async(dispatch_get_main_queue(), ^{
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSLog(@"error:%@",error);
if(isReFresh)
[self.tableView.mj_header endRefreshing ];
else [self.tableView.mj_footer endRefreshing ];
});
}
} else{
//网络问题
dispatch_async(dispatch_get_main_queue(), ^{
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
[KSToastView ks_showToast:@"无法连接网络，请检查网络设置" duration:3.0f];
if(isReFresh){
//加载本地条目
[self.tableView.mj_header endRefreshing];
}
else [self.tableView.mj_footer endRefreshing ];
});
}});
}
（2）不可刷新
#pragma mark -- 获取后台数据
// 获取任务信息
- (void)getDetailTaskInfo {
NSString *urlStr = [NSString stringWithFormat:@"%@%@",BASE_URL, TaskDetailInfo_URL];
NSDictionary *jsonParam = @{ @"id" : @(self.taskId)};
NSLog(@"--%zd:",self.taskId);
NSLog(@"urlStr:%@",urlStr);
dispatch_queue_t queue = dispatch_queue_create([@"getDetailTaskInfo" UTF8String], NULL);
dispatch_async(queue, ^{
NSData *data = [WebGetDataUtil getDataByURL:[NSURL URLWithString:urlStr ] withJsonParam:jsonParam];
if(data){
NSError *error;
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:&error];
// NSLog(@"loginDic = %@", dic);
if (dic) {
NSInteger code = [[dic objectForKey:@"code"]integerValue];
dispatch_async(dispatch_get_main_queue(), ^{
if (code == 1) {
NSDictionary *task = [dic objectForKey:@"data"];
self.taskData = task;
[self updateViewData:task];
[self setView];
}else {
[KSToastView ks_showToast:[dic objectForKey:@"msg"] duration:3.0f];
}
});
}
}else{
dispatch_async(dispatch_get_main_queue(), ^{
[KSToastView ks_showToast:@"网络连接失败" duration:3.0f];
});
}
});
}
