使用EKEventEditViewController时崩溃 [英] crash when using EKEventEditViewController

问题描述

我有一个奇怪的崩溃，我不知道如何调试...
这是代码：

I have a weird crash that I don't know how to debug... Here is the code:

-(void) addEventButtonPressed:(UIButton*)button{
DLog(@"Add new event");
// If event is nil, a new event is created and added to the specified event store. New events are 
// added to the default calendar. An exception is raised if set to an event that is not in the 
// specified event store.
// When add button is pushed, create an EKEventEditViewController to display the event.
EKEventEditViewController *addController = [[EKEventEditViewController alloc] initWithNibName:nil bundle:nil];

// set the addController's event store to the current event store.
addController.eventStore = self.eventStore;
addController.editViewDelegate = self;

// present EventsAddViewController as a modal view controller
[self presentModalViewController:addController animated:YES];

}

我的应用程序在崩溃后崩溃了在这一行的时间：
[self presentModalViewController：addController animated：YES];

My app crashes after a looong time at this line: [self presentModalViewController:addController animated:YES];

我正在使用ARC。
任何线索？
谢谢！

I am using ARC. Any clues? Thanks!

我的控制台只是说 EXC_BAD_ACCESS（代码= 2，地址= 0xbf7ffff4）

似乎 eventStore 需要在传递给 addController 或者你遇到了崩溃。在我的情况下，它是零。

It seems eventStore needs to be initialized before passing it to addController or you get a crash. In my case it was nil.

推荐答案

确保您从主线程呈现EKEventEditViewController;如果你从辅助线程中呈现它，它将崩溃（并不总是，但通常）。

Make sure that you are presenting the EKEventEditViewController from the main thread; it will crash (not always, but usually) if you present it from a secondary thread.
