任何人都知道为什么这个根View Controller's viewDidLoad在发布时被调用了两次？这让我疯了!
这是第一次到第一次的堆栈跟踪viewDidLoad:
#0 0x0000276a in -[RootViewController viewDidLoad] at RootViewController.m:71
#1 0x3097548f in -[UIViewController view]
#2 0x00002734 in -[RootViewController initWithCoder:] at RootViewController.m:39
#3 0x30ab5ce4 in -[UIClassSwapper initWithCoder:]
#4 0x30514636 in _decodeObjectBinary
#5 0x30514035 in _decodeObject
#6 0x30ab5a1d in -[UIRuntimeConnection initWithCoder:]
#7 0x30514636 in _decodeObjectBinary
#8 0x30515f27 in -[NSKeyedUnarchiver _decodeArrayOfObjectsForKey:]
#9 0x305163b0 in -[NSArray(NSArray) initWithCoder:]
#10 0x30514636 in _decodeObjectBinary
#11 0x30514035 in _decodeObject
#12 0x30ab4dde in -[UINib instantiateWithOptions:owner:loadingResourcesFromBundle:]
#13 0x30ab6eb3 in -[NSBundle(NSBundleAdditions) loadNibNamed:owner:options:]
#14 0x308f85f1 in …我viewDidLoad在视图控制器中被调用两次.一旦通过[UIViewController View],并通过第二次[UINib instanciateWithOwner:Options].为什么会这样？可以预防吗？
谢谢
