在 Objective C 中访问日历事件 GData
我想知道是否有人知道如何在 Objective C 应用程序中访问谷歌日历中的数据。我正在尝试创建一个 iPhone 应用程序来访问数据、处理数据并以自定义格式显示数据。
我的项目文件中有源代码，它们编译得很好，但我在实际获取数据时遇到了困难。谁能帮我一些帮助。多谢！
更新：
好吧，我在谷歌的网站上发现了一个简单的东西，它给出了一些简单的解释，但是当我使用提供的代码时，我得到“SIGABRT”，
我确实相信错误在于 didFinishSelector:@selector(ticket: FinishWithFeed：错误:)。
在方法中处理设置一切。
ticket = [service fetchFeedWithURL:feedURL
delegate:self
didFinishSelector:@selector(ticket:finishedWithFeed:error:)];
didFinishSelector 方法如下，
- (void)ticket:(GDataServiceTicket *)ticket
finishedWithFeed:(GDataFeedCalendar *)feed
error:(NSError *)error {
if (error == nil) {
NSArray *entries = [feed entries];
if ([entries count] > 0) {
GDataEntryCalendar *firstCalendar = [entries objectAtIndex:0];
GDataTextConstruct *titleTextConstruct = [firstCalendar title];
NSString *title = [titleTextConstruct stringValue];
NSLog(@"first calendar's title: %@", title);
} else {
NSLog(@"the user has no calendars");
}
} else {
NSLog(@"fetch error: %@", error);
}
}
每次尝试访问此方法时都会出现错误。有人知道为什么吗？
I was wondering if anyone knew how to access data from a google calendar in an objective c application. I am trying to create an iPhone application that access the data, process it and display it in a custom format.
I have the sources in the project file and they are compiling fine, but I am having trouble actually getting the data. Can anyone lend me some help. Thanks a lot!
UPDATE:
Alright, I found a simple thing on google's website that gives a brief explanation of stuff, however when I go to use the code provided I get "SIGABRT"
I do believe the error is lying in the didFinishSelector:@selector(ticket:finishedWithFeed:error:).
In method to handle setting everything up.
ticket = [service fetchFeedWithURL:feedURL
delegate:self
didFinishSelector:@selector(ticket:finishedWithFeed:error:)];
The didFinishSelector method is as follows
- (void)ticket:(GDataServiceTicket *)ticket
finishedWithFeed:(GDataFeedCalendar *)feed
error:(NSError *)error {
if (error == nil) {
NSArray *entries = [feed entries];
if ([entries count] > 0) {
GDataEntryCalendar *firstCalendar = [entries objectAtIndex:0];
GDataTextConstruct *titleTextConstruct = [firstCalendar title];
NSString *title = [titleTextConstruct stringValue];
NSLog(@"first calendar's title: %@", title);
} else {
NSLog(@"the user has no calendars");
}
} else {
NSLog(@"fetch error: %@", error);
}
}
I get an error every time it tries to access this method. Does anyone have an idea why?

好吧，另一个论坛上的某人帮助了我，并给了我以下解决方案，到目前为止它对我有效。尽管我确实注意到编辑完日历后您必须退出谷歌，否则它会因某种原因无法工作。

该论坛中没有说明的是您需要在接口文件中声明以下内容
Alright someone on another forum helped me out and gave me the following solution and it is working thus far for me. Though I did notice you have to log out of google once you are done editing a calendar or it will not work for some reason.

What is not stated in that forum is that you will need to declare the following in the interface file
