有时候须要根据tag来获取cell,须要建立NSIndexpath,咱们可能会这么用:数组
NSIndexPath *indexPath = [[NSIndexPath alloc] initWithIndex:tag];spa
没有报错,但很遗憾的是经过这样的indexPath,你是怎么都获取不到cell的!正确的建立方法是:
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:row inSection:section];
code
if ([self.dataArray indexOfObject:model] != NSNotFound) {//数组中某一元素在数组中的位置 NSInteger inde =[self.dataArray indexOfObject:model] ; NSLog(@"-2---%ld----",inde); model.status = @"1"; [self.dataArray replaceObjectAtIndex:inde withObject:model];//替换数组中某一元素的值 NSIndexPath *indexPath = [NSIndexPath indexPathForRow:inde inSection:0];//建立NSIndexpath [self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationNone];//刷新表格的某一行 }
