关于UITableView横扫删除的问题 [NSMutableArray removeObjectAtIndex]
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
[myArray removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
else if (editingStyle == UITableViewCellEditingStyleInsert) {
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view.
}
}
在这里 myArray 是一个数组 是数据成员 并且我已经alloc，但是当我在模拟器中横扫的时候老是在remove那里报错，报的这个错

解决办法：
数组应该初始化称NSMutableArray 我定义成NSArray 了
NSMutablearray * myarray = [[NSMutableArray alloc] init];版权声明：本文为博主原创文章，未经博主允许不得转载。
