强势插入:在编译.app后与.app同根目录文件夹下会有一个对应的.dSYM文件,要养成一个好习惯,发布一版app时同时保存对应的.dSYM文件。

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?

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!!
