先来几张效果图吧

1.首页 首页.png 

- (void)setFrame:(CGRect)frame{ 
static CGFloat margin = 10;  
frame.origin.x = margin;    
frame.size.width -= 2 * frame.origin.x;  
frame.origin.y += margin;  
frame.size.height -= margin;   
[super setFrame:frame];}


UIView *view = [[UIView alloc]initWithFrame:CGRectMake(10, 0, self.frame.size.width-20, self.frame.size.height)];
view.backgroundColor = [UIColor colorWithRed:0.96 green:0.96 blue:0.96 alpha:1.00];
view.layer.cornerRadius = 15;
view.layer.masksToBounds = YES;
self.selectedBackgroundView = view;

2.几种cell的自定义

A.png B.png

string = [NSString stringWithFormat:@"<head><style>img{max-width:14;max-height:14}</style></head>%@",string];
NSMutableAttributedString * messageAttrStr = [[NSMutableAttributedString alloc] initWithData:[string dataUsingEncoding:NSUnicodeStringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType} documentAttributes:nil error:nil]; ```

Time.png 
-(void)setTimeText:(NSInteger)dataLine{   
 NSString * timeString;  
  NSDate * todayDate = [NSDate date];//当前时间    
NSDate * pastDate = [NSDate dateWithTimeIntervalSince1970:dataLine];//发帖时间
    NSDateFormatter * format = [[NSDateFormatter alloc] init];  
  NSCalendar * calendar = [NSCalendar currentCalendar]; 
   NSInteger unit =  NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond; 
   NSDateComponents * comDate =  [calendar components:unit fromDate:pastDate toDate:todayDate options:NSCalendarWrapComponents];//时间差值的组件
  if (comDate.year < 1) {//判断是否今年   
        if ([calendar isDateInToday:pastDate]) {//判断是否今天   
           if (comDate.hour >= 1) {//判断是否大于1小时 
               format.dateFormat = @"今天HH:mm";             
               timeString = [format stringFromDate:pastDate];      
            }else if(comDate.hour < 1 && comDate.minute >= 1){            //判断是否小于1小时     
               timeString = [NSString stringWithFormat:@"%2ld分钟前",(long)comDate.minute];      
            }else if(comDate.hour < 1 && comDate.minute < 1 && comDate.second >= 0){//判断是否在一分钟内
                timeString =@"刚刚";         
             }     
        }else if ([calendar isDateInYesterday:pastDate]){  //判断是否昨天      
          format.dateFormat = @"昨天HH:mm";       
           timeString = [format stringFromDate:pastDate];     
        }else{ // 前天之前       
          format.dateFormat = @"MM-dd HH:mm";       
          timeString = [format stringFromDate:pastDate];     
         }  
  }else{ 
       format.dateFormat = @"yyyy-MM-dd HH:mm";
       timeString = [format stringFromDate:pastDate];  
  }  
  _time.text = timeString;
}

8.设置界面 Paste_Image.png 

NSString  *Path = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject];
- (NSInteger)getSizeOfPath:(NSString *)Path {
    NSFileManager *mgr = [NSFileManager defaultManager];
    NSArray *subpaths = [mgr subpathsAtPath:Path];
    NSInteger totalSize = 0;
    for (NSString *subPath in subpaths) {  
      NSString *filePath = [directoryPath stringByAppendingPathComponent:subPath];

9.具体帖子内容界面 Paste_Image.png

9.1控件布局

9.2内容布局 Paste_Image.png 

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler ;

里的url链接来进行判断处理。

10.其他

1.点击Tabbar按钮实现滑动到顶部或刷新

Paste_Image.png 首先是在自定义的UITabBarController里的UITabBarControllerDelegate的方法 
-(BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController;```
里面来判断当前点击的是哪个按钮对应的控制器，然后根据控制器的`view`的`contentOffset`来判断是否已经在顶部，不在则滑动到顶部，在则执行刷新操作。

3.框架使用
- 网络请求  [AFNetworking](https://github.com/AFNetworking/AFNetworking)
- 图片下载  [SDWebImage](https://github.com/rs/SDWebImage)
- 数据解析  [MJExtension](https://github.com/CoderMJLee/MJExtension)
- HUD显示 [SVProgressHUD](https://github.com/SVProgressHUD/SVProgressHUD)
- 刷      新   [MJRefresh](https://github.com/CoderMJLee/MJRefresh)
- 崩溃日志  [Bugly](https://github.com/BuglyDevTeam/Bugly-iOS)
- 然后框架导入使用的CocoaPods，不过最近Carthage比较流行，最近也在学习Carthage。

4.这是我的第一个正式且上架的APP，所以也一直在更新中，主要是在iPhone手机上使用，所以在iPad上显示时会出现有些布局样式不一样，因为没有进行iPad专门的适配，都是交给系统来做的。然后因为第一个嘛，所以怕不熟练，用的是最熟的OC写的，不过接下来的几个APP已经转swift了，swift写起来还是很舒服的。

## 11.最后因为我当初代码是直接提交到国内的Coding上去的，还是私有库，同时因为懒癌，所以就没有再上传到github上，所以大家是看不到代码了(话说代码我写的有些乱，也没多少注释。)
