Question

我已经从IOS的共享谷歌日历中检索了我的活动，并在桌面视图中显示它们。至于现在，他们的简化显示为事件标题为标题，事件时间为副标题。我想把日期（eventtime）用作一个节目标题，以便例如3月31日所有事件在一个组中显示，时间作为“正确的细节”

我的代码如下所示：

@interface MasterViewController () {
    NSArray *events;
}
@end

@implementation MasterViewController

-(void)viewDidAppear:(BOOL)animated
{
    //show loader view
    //[HUD showUIBlockingIndicatorWithText:@"Fetching JSON"];


    //make HTTP call
    NSString* searchCall = [NSString stringWithFormat:@"http://www.google.com/calendar/feeds/kao1d80fd2u5kh7268caop11o4%%40group.calendar.google.com/public/full?alt=json"];

    [JSONHTTPClient getJSONFromURLWithString: searchCall
                                  completion:^(NSDictionary *json, JSONModelError *err) {

                                      //got JSON back
                                      NSLog(@"Got JSON from web: %@", json);

                                      if (err) {
                                          [[[UIAlertView alloc] initWithTitle:@"Error"
                                                                      message:[err localizedDescription]
                                                                     delegate:nil
                                                            cancelButtonTitle:@"Close"
                                                            otherButtonTitles: nil] show];
                                          return;
                                      }

                                      //initialize the models
                                      events = [CalendarModel arrayOfModelsFromDictionaries:
                                                json[@"feed"][@"entry"]
                                                ];

                                      if (events) NSLog(@"Loaded successfully models");

                                      //show the videos
                                      [self.tableView reloadData];

                                  }];


}
;

我已经在网上找到了这个代码，但是他没有获得JSON数据，但我相信，从iPhone日历中获取数据。

我有没有办法将我的json event.startdate用作节头？

Answer 1

就个人而言，我会忽略你在那里发布的代码，因为它不是你想要做的。

您设置标题和副标题的代码部分是以下两行： cell.textLabel.text = [NSString stringWithFormat：@“％@”，event.title]; cell.detailTextLabel.text = [formatter stringFromDate：gmtDate];

因此，如果您希望标题为日期，只需将其作为cell.textLabel.text值。

Answer 2

所以，如果你想做部分。

确保部分数量大于1.

然后你可能想看看这些表方法。根据您的具体情况和定制需求，您可以相应地进行更改。

(NSString*) tableView:(UITableView*)tableView titleForHeaderInSection:(NSInteger)section{
   }

(CGFloat)tableView:(UITableView*)tableView heightForHeaderInSection:(NSInteger)section{
 }

(UIView*)tableView:(UITableView*)table viewForHeaderInSection:(NsInteger)section{
}

我希望这会有所帮助。我通常会有一个例子，我目前没有最多的可用时间，但如果需要，我可以提供一个。

小心：）

有JSON数据，希望与IOS6应用程序中的部分一起显示
