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];
}];
}
;
#pragma mark - table methods
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return events.count;
}
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
CalendarModel* event = events[indexPath.row];
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"yyyy-MM-dd'T'HH:mm:ss.SSSzzz";
NSDate *gmtDate = [formatter dateFromString: [[event.time objectAtIndex:0] startTime]];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];
cell.textLabel.text = [NSString stringWithFormat:@"%@",
event.title
];
cell.detailTextLabel.text = [formatter stringFromDate: gmtDate];
return cell;
}
@end
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？
答案 0 :(得分：0)
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。
答案 1 :(得分：0)
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：）
