我想知道是否有人對此問題有解釋/解決方案。我使用GData API來獲取日曆信息並將其存儲到NSDictionary中,並在以後訪問它。但是,當我調用函數來獲取數據時,在我調用函數後,好像日曆訪問正在發生許多行。GData日曆執行順序
在下面的代碼中,我立即調用loadGoogleCalendarEvents,它會去獲取事件並執行一些更多的處理,但是我的應用程序正在「跳過」它,添加按鈕並執行其他操作,它獲取日曆的東西。
有沒有人對此有過解釋?
- (void)viewDidLoad
{
self.dayDictionary = [NSMutableDictionary dictionary];
[self loadGoogleCalendarEvents];
UIImage* fImage = [UIImage imageNamed:@"facebook_med"];
CGRect fbuttonFrame = CGRectMake(220, 9, 25, 25);
UIButton* fButton = [UIButton buttonWithType:UIButtonTypeCustom];
fButton.frame = fbuttonFrame;
[fButton addTarget:self action:@selector(pushFacebookButton) forControlEvents:UIControlEventTouchUpInside];
[fButton setBackgroundImage:fImage forState:UIControlStateNormal];
[fButton setShowsTouchWhenHighlighted:YES];
UIImage* tImage = [UIImage imageNamed:@"twitter_med"];
CGRect tbuttonFrame = CGRectMake(255, 9, 25, 25);
UIButton* tButton = [UIButton buttonWithType:UIButtonTypeCustom];
tButton.frame = tbuttonFrame;
[tButton addTarget:self action:@selector(pushTwitterButton) forControlEvents:UIControlEventTouchUpInside];
[tButton setBackgroundImage:tImage forState:UIControlStateNormal];
[tButton setShowsTouchWhenHighlighted:YES];
UIButton* aButton = [[UIButton buttonWithType:UIButtonTypeInfoLight] retain];
aButton.frame = CGRectMake(285,9, 25, 25);
[aButton addTarget:self action:@selector(pushAboutButton) forControlEvents:UIControlEventTouchUpInside];
[aButton setShowsTouchWhenHighlighted:YES];
[navBar addSubview:fButton];
[navBar addSubview:tButton];
[navBar addSubview:aButton];
[super viewDidLoad];
}
非常感謝您的回答。我沒有意識到這會發生(不知道爲什麼我沒有意識到這一點),考慮到我已經完成了URL訪問,當我想要時,正確的順序發生。我能夠爲此做一些工作,並得到它的工作。 – MZimmerman6 2011-05-26 13:34:10
