在我的情況下，我有兩個視圖在標籤欄控制器（類別和家庭），一個集合視圖和一個表視圖。 在表格視圖中，當用戶在其標籤欄item.I上想要加載數據時，只有用戶點擊（Home）時纔開始加載數據。我使用的是AFNetworking，我在viewDidLoad中調用了我的數據加載方法。同樣的事情發生與收集view.please幫助我與this.hope你的幫助謝謝。我附加了我用來將數據加載到表視圖的部分代碼。如何在用戶在ios中查看視圖之前加載數據？
- (void)viewDidLoad {
[super viewDidLoad];
[self.view addSubview:self.homeTableView];
// [self homeviewData];
SWRevealViewController *revealController = self.revealViewController;
if (revealController) {
[self.sidebarButton setTarget:self.revealViewController];
[self.sidebarButton setAction:@selector(revealToggle:)];
[self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];
}
// Do any additional setup after loading the view.
}
- (void)viewWillAppear:(BOOL)animated
{
[self homeTableView];
}

[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
