我有一個奇怪的問題,每當我在iPad模擬器上運行我的應用程序它完美的作品,但如果我嘗試在真正的設備(iPad空氣iOS 7.0.4)嘗試這段代碼。模擬器上的Xcode應用程序工作,在真實設備崩潰
我有:
嵌入在主詳細拆分視圖控制器導航控制器(將調用A) - >更換賽格瑞 - >
的UITableViewController - >更換賽格瑞 - >
someViewController(將呼叫B)
現在..將segue替換回導航控制器(全部爲主控細節),並且在此僅在實際設備上墜毀,僅給出:(lldb)
現在這是B實施
- (IBAction)backToTable:(id)sender
{
id detail = self.splitViewController.viewControllers[1];
if(detail) { // iPad
[self performSegueWithIdentifier:@"backToTable" sender:self];
}
else // iPhone
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:@"backToTable"]){
ViewControllerA *destViewController = [[[segue destinationViewController] viewControllers] objectAtIndex:0];
destViewController.boolForSegue = @"true";
}
}
,這是一個
.h
@property (strong) NSString *boolForSegue;
.m
-(void)viewWillAppear:(BOOL)animated
{
if ([_boolForSegue isEqualToString:@"true"]){
[self unlockView];
}
}
- (void)unlockView
{
[self performSegueWithIdentifier:@"mySegue" sender:self];
}
我再說一遍,在模擬器工作完全沒有問題的。可能是什麼問題呢??
