Hi I have been looking around for this solution but cannot find it.
Have created a loading view controller to show all the loading process which has UILabel, UIActivityIndicator. After finishing loading I want to push to a tab bar controller view.
But the tricky part is I have three different NSOperations working while loading the data. Cannot figure out when to push the view from the loading view controller to the tab bar controller.
Any help really appreciated.
Should be simple enough. Have each operation call into a single shared method when it completes; that method should check each operation’s isFinished. If all three are done, the whole thing’s ready, and you can bring up your main tab-bar controller.
