我正在处理聊天视图。为此，我使用了以下代码：Chat Code 这工作正常。现在我在UItableViewCell中使用了UIcollectionView。集合视图工作正常。但问题是doselect方法没有调用UICollectionView以及UITableView。请帮我。我非常需要你的帮助。
我在UITableViewCell类中使用了这段代码：
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
self.backgroundColor = [UIColor clearColor];
if ([[UIDevice currentDevice].systemVersion floatValue] < 7.0f) {
self.textLabel.backgroundColor = [UIColor whiteColor];
}
self.textLabel.font = [UIFont systemFontOfSize:14.0f];
self.textLabel.lineBreakMode = NSLineBreakByWordWrapping;
self.textLabel.numberOfLines = 0;
self.textLabel.textAlignment = NSTextAlignmentLeft;
self.textLabel.textColor = [UIColor blackColor];
_timestampLabel = [[UILabel alloc] init];
_timestampLabel.autoresizingMask = UIViewAutoresizingFlexibleWidth;
_timestampLabel.textAlignment = NSTextAlignmentCenter;
_timestampLabel.backgroundColor = [UIColor clearColor];
_timestampLabel.font = [UIFont systemFontOfSize:12.0f];
_timestampLabel.textColor = [UIColor colorWithRed:0.4 green:0.4 blue:0.4 alpha:1.0];
_timestampLabel.frame = CGRectMake(0.0f, 12, self.bounds.size.width, 18);
[self.contentView addSubview:_timestampLabel];
messageBackgroundView = [[UIImageView alloc] initWithFrame:self.textLabel.frame];
[self.contentView insertSubview:messageBackgroundView belowSubview:self.textLabel];
self.AvatarImageView = [[UIImageView alloc] initWithFrame:CGRectMake(5,10+TOP_MARGIN, 50, 50)];
[self.contentView addSubview:self.AvatarImageView];
CALayer * l = [self.AvatarImageView layer];
[l setMasksToBounds:YES];
[l setCornerRadius:self.AvatarImageView.frame.size.width/2.0];
self.selectionStyle = UITableViewCellSelectionStyleNone;
UICollectionViewFlowLayout *layout = [[UICollectionViewFlowLayout alloc] init];
layout.scrollDirection = UICollectionViewScrollDirectionHorizontal;
self.collectionView = [[UICollectionView alloc] initWithFrame:CGRectZero collectionViewLayout:layout];
[self.collectionView registerNib:[UINib nibWithNibName:@"ImageCollection" bundle:nil] forCellWithReuseIdentifier:@"Cell"];
[self.collectionView setUserInteractionEnabled:YES];
self.collectionView.backgroundColor = [UIColor clearColor];
[self.contentView addSubview:self.collectionView];
[messageBackgroundView setUserInteractionEnabled:YES];
[self.contentView setUserInteractionEnabled:YES];
// UITapGestureRecognizer *lpgr // = [[UITapGestureRecognizer alloc] // initWithTarget:self action:@selector(tapRecognized:)]; // lpgr.numberOfTapsRequired
= 1; // lpgr.delegate = self; // [self.collectionView addGestureRecognizer:lpgr];
}
[self setUserInteractionEnabled:YES];
return self; }
在UIViewController中我在tableView cellForRowAtIndexPath中使用了这段代码：
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *L_CellIdentifier = @"SPHTextBubbleCell";
self.documentsArray = [[NSMutableArray alloc]init];
self.documentsArray = [[self.messagesArray objectAtIndex:indexPath.row]valueForKey:@"Attachments"];
SPHTextBubbleCell *cell = [tableView dequeueReusableCellWithIdentifier:L_CellIdentifier];
cell.userInteractionEnabled = YES;
if (cell == nil)
{
cell = [[SPHTextBubbleCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:L_CellIdentifier];
}
// cell.bubbletype=(([[[self.messagesArray objectAtIndex:indexPath.row]valueForKey:@"MessageFromId"]intValue] == 1))?@"LEFT":@"RIGHT";
if ([[[self.messagesArray objectAtIndex:indexPath.row]valueForKey:@"MessageFromId"]intValue] == 1) {
cell.bubbletype = @"RIGHT";
}
else
{
cell.bubbletype = @"LEFT";
}
[cell setBackgroundColor:[UIColor clearColor]];
cell.textLabel.text = [[self.messagesArray objectAtIndex:indexPath.row]valueForKey:@"Content"];
cell.textLabel.tag=indexPath.row;
NSString *dateString = [NSString stringWithFormat:@"%@",[self mfDateFromDotNetJSON:[[self.messagesArray objectAtIndex:indexPath.row]valueForKey:@"UpdatedOn"]]];
NSLog(@"dateString..%@",dateString);
NSString *myString = [NSString stringWithFormat:@"%@",dateString];
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = @"yyyy-MM-dd HH:mm:ss ZZZ";
NSDate *yourDate = [dateFormatter dateFromString:myString];
// NSTimeZone *utc = [NSTimeZone timeZoneWithAbbreviation:@"UTC"];
// [dateFormatter setTimeZone:utc];
dateFormatter.dateFormat = @"dd-MMM-yy HH:mm";
NSString *newString = [dateFormatter stringFromDate:yourDate];
NSLog(@"newString..%@",newString);
if ([self.documentsArray count]!=0)
{
cell.CustomDelegate = self;
[cell.collectionView setUserInteractionEnabled:YES];
[cell.collectionView setDelegate:self];
[cell.collectionView setDataSource:self];
cell.collectionView.delegate =self;
cell.collectionView.dataSource = self;
[cell.collectionView reloadData];
[cell.collectionView setHidden:NO];
[cell.collectionView setBackgroundColor:[UIColor clearColor]];
}
else
{
[cell.collectionView setHidden:YES];
}
cell.collectionView.tag =indexPath.row;
cell.timestampLabel.text = newString;
[cell.AvatarImageView sd_setImageWithURL:([[[self.messagesArray objectAtIndex:indexPath.row]valueForKey:@"MessageFromId"]intValue] == 1)?[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",imageURLLive,[[[self.messagesArray objectAtIndex:indexPath.row]valueForKey:@"SellerPicture"] valueForKey:@"PictureUrl"]]]:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",imageURLLive,[[[self.messagesArray objectAtIndex:indexPath.row]valueForKey:@"BuyerPicture"] valueForKey:@"PictureUrl"]]]
placeholderImage:[UIImage imageNamed:@"Nav-profile1.png"]];
return cell;
}

如果您的问题是您的UICollectionView点击不会导致UITableViewCell被选中，那么您可以通过继承UICollectionView并根据自己的喜好修改hitTest函数来绕过它。
这个允许您点击集合视图项之外的任何内容来选择表格单元格，但集合视图项本身将阻止点击并根据需要处理它们。

在我的案例中，修改%Super.Context = "";
方法并不起作用。我决定使用hitTest。

不要忘记设置delegate和dataSource。
self.tableView.delegate = self;
self.tableView.dataSource = self;
