我有一個初始表unreadmessagesArrays,女巫顯示完美。 但要滾動至底部,並加載數據的另一行.. 我用這個:滾動到底部後在表格視圖中加載數據
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{
CGFloat currentOffset = scrollView.contentOffset.y;
CGFloat maximumOffset = scrollView.contentSize.height - scrollView.frame.size.height;
if (maximumOffset - currentOffset <= 10.0) {
[self insertRowInTableView];
}
}
-(void)insertRowInTableView {
[self.unreadmessagesArray addObject:self.messagesIfScroll];
[mytableView beginUpdates];
NSArray *paths = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:([self.unreadmessagesArray count] - 1) inSection:0]];
[mytableView insertRowsAtIndexPaths:paths withRowAnimation:NO];
[mytableView endUpdates];
[mytableView reloadData];
}
-(void)getMessagesIfScollToBottom {
self.messagesIfScroll = [NSMutableArray arrayWithArray:responseA];
}
我得到的錯誤是:Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayI addObject:]: unrecognized selector sent to instance 0xa20b620'
問題出在哪裏? 謝謝
同樣的問題! – lyn87 2014-10-17 17:06:55
'unreadmessagesArray'的類型是什麼?這是NSMutableArray還是NSArray? – 2014-10-18 05:43:18
都是unreadmessageaArray,而messagesIfScroll是NSMutalearray! – lyn87 2014-10-19 12:17:39
