这不是你自己写的代码。但至少它确认了是对象调用了一个没有实现的方法。
-(IBAction)bookmarkButtonPressed { self.master.isBookmarked = !self.master.isBookmarked; // Update shared bookmarks if (self.master.isBookmarked) [[RMBookmarks sharedBookmarks] bookmarkMaster:self.master]; else [[RMBookmarks sharedBookmarks] unbookmarkMaster:self.master]; // Update UI [self updateBookmarkImage]; }
看起来没什么问题再检查一下storyboard (XIB文件) 确认按钮连接的正确性。

-(IBAction)bookmarkButtonPressed:(id)sender { // Remain unchanged.. }
当然你也可以简单地在XIB文件上删除错误的连接然后重新连接方法使XIB文件连接到正确的方法上。两者方法都行。

这看起来跟前面那个崩溃日志很像。是另一个SIGABRT 异常。 你可能想知道是否是相同的问题发送信息到一个没有实现相应方法的对象?
6 Rage Masters 0x00088c66 -[RMBookmarksViewController tableView:commitEditingStyle:forRowAtIndexPath:] (RMBookmarksViewController.m:68)
这是UITableViewDataSource 的一个方法. 呵呵?! 毫无疑问苹果已经实现了该方法 —— 你可以重载它, 但不像是还没有实现。而且,这是个可选的委派方法。 所以问题不是调用了一个没有实现的方法。

帧 5, UITableView调用了它自己的另一个方法 deleteRowsAtIndexPaths:withRowAnimation: 然后是看起来像苹果内部方法的_endCellAnimationsWithContext: 被调用。然后Foundation framework发生异常handleFailureInMethod:object:file:lineNumber:description:.
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationAutomatic]; }
发现问题了吗? 给你点时间仔细看一下。
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { RMMaster *masterToDelete = [bookmarks objectAtIndex:indexPath.row]; [bookmarks removeObject:masterToDelete]; [[RMBookmarks sharedBookmarks] unbookmarkMaster:masterToDelete]; [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationAutomatic]; }
搞定了!走起讨厌的 bug!!
