Ios 引起SIGABRT的SET编辑方法
我正在写一本书,叫《iphone编程》。我正在阅读第11章,在这里您实现了自己的设置编辑方法:Ios 引起SIGABRT的SET编辑方法,ios,Ios,我正在写一本书,叫《iphone编程》。我正在阅读第11章,在这里您实现了自己的设置编辑方法: - (void)setEditing:(BOOL)editing animated:(BOOL)animated { [super setEditing:editing animated:animated]; if( editing) { NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[teams coun
- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{
[super setEditing:editing animated:animated];
if( editing) {
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[teams count] inSection:0];
NSArray *paths = [NSArray arrayWithObject:indexPath];
[[self tableView] insertRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationLeft];
}
else {
/*
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[teams count] inSection:0];
NSArray *paths = [NSArray arrayWithObject:indexPath];
[[self tableView] deleteRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationFade];
*/
}
}
当我运行这个程序时,整个应用程序会执行一个Sigabort,除此之外没有任何其他信息。引起问题的线路如下:
[[self tableView] insertRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationLeft];
我不确定我做错了什么。还有什么好看的
