我试图在另一个视图以模态方式呈现后直接显示模态视图(第二个是出现的加载视图).

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    // Show load
    LoadViewController *loader = [[LoadViewController alloc] init];
    [self presentModalViewController: loader animated:NO];
    [loader release];
}

但是当我这样做时,我得到一个"程序接收信号:"EXC_BAD_ACCESS"." 错误.

堆栈跟踪是:

0  0x30b43234 in -[UIWindowController transitionViewDidComplete:fromView:toView:]
1  0x3095828e in -[UITransitionView notifyDidCompleteTransition:]
2  0x3091af0d in -[UIViewAnimationState sendDelegateAnimationDidStop:finished:]
3  0x3091ad7c in -[UIViewAnimationState animationDidStop:finished:]
4  0x0051e331 in run_animation_callbacks
5  0x0051e109 in CA::timer_callback
6  0x302454a0 in CFRunLoopRunSpecific
7  0x30244628 in CFRunLoopRunInMode
8  0x32044c31 in GSEventRunModal
9  0x32044cf6 in GSEventRun
10 0x309021ee in UIApplicationMain
11 0x00002154 in main at main.m:14

有任何想法吗？我完全难过了!加载视图为空,因此肯定没有任何事情导致错误.是否与在同一个事件循环中以模态方式启动2个视图有关？ …
