ios - iOS 中 NSmutableArrays 的 NSMuatableArray 的 RemoveObjectAtIndex 正在崩溃
<p><p>我正在使用 <code>NSMutableArray</code> 并尝试从 <code>NSMutableArray</code> 中删除对象，然后它崩溃了</p>
<p><strong>[ removeObjectAtIndex:indexPath.row];</strong></p>
<p><code>.h</code> 就像</p>
<pre><code>NSMutableArray *sectionsArray;
@property (nonatomic, retain) NSMutableArray *sectionsArray;
.m is like:
@synthesize sectionsArray;
#pragma mark - TableView Delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Perform segue to candy detail
NSLog(@"section: %d row: %d", indexPath.section, indexPath.row);
NSLog(@"section :%@", [ objectAtIndex:indexPath.row]);
[ removeObjectAtIndex:indexPath.row];
// withRowAnimation:UITableViewRowAnimationLeft];
}
</code></pre>
<p>崩溃日志是这样的:</p>
<pre><code> 2014-01-28 11:56:24.989 CandySearch section: 2 row: 0
2014-01-28 11:56:24.991 CandySearch section :<Candy: 0x75a5a70>

</code></pre>
<p>我可以看到该索引处的对象。但它仍然崩溃
为什么？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>位于索引“indexPath.section”上的数组是一个 NSArray 对象，而不是一个 NSMutableArray
只需阅读崩溃日志:
<strong>NSArrayI removeObjectAtIndex:</strong></p>
<p>请检查你的sectionArray的对象</p></p>
