我正在尝试构建一个可以获取Google日历信息的应用程序,例如日历,事件等,但我遇到了一个大问题.
这是我的代码：
#define GoogleClientID @"client id"
#define GoogleClientSecret @"secret"
#define GoogleAuthURL @"https://accounts.google.com/o/oauth2/auth"
#define GoogleTokenURL @"https://accounts.google.com/o/oauth2/token"
NSString *const kKeychainItemName = @"Calendar Panel: Google Calendar";
- (instancetype)initWithViewController: (UIViewController*) viewController;
{
self = [super init];
if (self) {
_viewController = viewController;
}
return self;
}
- (BOOL)isSignedIn {
NSString *name = [self signedInUsername];
return (name != nil);
}
- (NSString *)signedInUsername {
// Get the email address of the signed-in user
GTMOAuth2Authentication *auth = self.calendarService.authorizer;
BOOL isSignedIn = auth.canAuthorize;
if (isSignedIn) {
return auth.userEmail;
} else {
return nil;
}
}
- (GTMOAuth2Authentication * )authForGoogle
{
//This URL is defined by the individual 3rd party APIs, be sure to read their documentation
NSURL * tokenURL = [NSURL URLWithString:GoogleTokenURL];
// We'll make up an arbitrary redirectURI. The controller will watch for
// the server to redirect the web view to this URI, but this URI will not be
// loaded, so it need not be for any actual web page. This needs to match the URI set as the
// redirect URI when configuring the app with Instagram.
NSString * redirectURI = @"urn:ietf:wg:oauth:2.0:oob";
GTMOAuth2Authentication * auth;
auth = [GTMOAuth2Authentication authenticationWithServiceProvider:@"lifebeat"
tokenURL:tokenURL
redirectURI:redirectURI
clientID:GoogleClientID
clientSecret:GoogleClientSecret];
auth.scope = @"https://www.googleapis.com/auth/userinfo.profile";
return auth;
}
- (void)signInToGoogle
{
if (![self isSignedIn]) {
GTMOAuth2Authentication * auth = [self authForGoogle];
// Display the authentication view
GTMOAuth2ViewControllerTouch * viewController = [[GTMOAuth2ViewControllerTouch alloc] initWithAuthentication:auth
authorizationURL:[NSURL URLWithString:GoogleAuthURL]
keychainItemName:@"GoogleKeychainName"
delegate:self
finishedSelector:@selector(viewController:finishedWithAuth:error:)];
[[self.viewController navigationController] pushViewController:viewController animated:YES];
} else
NSLog(@"Something wrong with the sign in procedure!");
}
- (void)viewController:(GTMOAuth2ViewControllerTouch * )viewController
finishedWithAuth:(GTMOAuth2Authentication * )auth
error:(NSError * )error
{
NSLog(@"finished");
NSLog(@"auth access token: %@", auth.accessToken);
self.calendarService.authorizer = auth;
[[self.viewController navigationController] popToViewController:self.viewController animated:NO];
if (error != nil) {
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Error Authorizing with Google"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
} else {
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Success Authorizing with Google"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
}
}
- (void)fetchCalendarList {
self.calendarList = nil;
self.calendarListFetchError = nil;
GTLServiceCalendar *service = self.calendarService;
GTLQueryCalendar *query = [GTLQueryCalendar queryForCalendarListList];
self.calendarListTicket = [service executeQuery:query
completionHandler:^(GTLServiceTicket *ticket,
id calendarList, NSError *error) {
// Callback
self.calendarList = calendarList;
self.calendarListFetchError = error;
self.calendarListTicket = nil;
NSLog(@"Fetched number of calendars: %@", self.calendarList);
//[self updateUI];
}];
//[self updateUI];
}
- (GTLServiceCalendar *)calendarService {
static GTLServiceCalendar *service = nil;
if (!service) {
service = [[GTLServiceCalendar alloc] init];
// Have the service object set tickets to fetch consecutive pages
// of the feed so we do not need to manually fetch them
service.shouldFetchNextPages = YES;
// Have the service object set tickets to retry temporary error conditions
// automatically
service.retryEnabled = YES;
}
return service;
}
@end
这是控制台输出：

2014-09-10 23:57:53.986 CalendarPanel[24383:60b] Fetched number of calendars: (null)
我的两个问题是：
1.我怎样摆脱这些冲突？
2.我的代码看起来不错吗？ (从用户那里获取所有日历)我认为使用这个GData类非常棘手,并且存在非常有限/或非常过时的信息.
最佳答案 而不是安装整个Pod尝试使用subpods
pod 'Google-API-Client/Calendar', '~> 1.0'
或者你需要的任何一个
pod 'Google-API-Client/Drive', '~> 1.0'
