Objective c 将子视图添加到单元格

setting the first responder view of the table but we don't know its type (cell/header/footer)
static NSString *textfield = @"textfield";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:textfield];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:textfield];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(15, 0, cell.frame.size.width, cell.frame.size.height)];
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
textField.clearButtonMode = UITextFieldViewModeAlways;
textField.returnKeyType = UIReturnKeyNext;
textField.autocapitalizationType = UITextAutocapitalizationTypeSentences;
textField.adjustsFontSizeToFitWidth = YES;
textField.placeholder = placeholderName;
textField.font = [UIFont fontWithName:@"HelveticaNeue-Light" size:17.0f];
textField.textColor = [UIColor colorWithRed:68.0f/255.0f green:68.0f/255.0f blue:68.0f/255.0f alpha:1.0];
textField.tag = curTag;
textField.text = @"aads";
[_fields setObject:textField forKey:[NSNumber numberWithInt:curTag]];
[textField addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
[textField becomeFirstResponder];
[cell.contentView addSubview:textField];
}
我也在努力
[cell.contentView bringSubviewToFront:textField];
及
[cell.contentView.window addSubview:textField]
但是我在牢房里没有uitextfield
如何创建视图:
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self)
{
_currentPage = 0;
_fields = [NSMutableDictionary dictionary];
[[PopupData inst] loadNewPortfolioPopupData];
[[NSBundle mainBundle] loadNibNamed:@"CustomPopupView" owner:self options:nil];
[self addSubview:_view];
[self mainPopupNavi];
// _tableView.bounces = NO;
}
return self;
}
乍一看,问题很可能是您的文本字段大小为0。您正在根据单元格的大小为其指定大小,但在执行此操作时,单元格的大小为0 如果你加上
textField.autoResizingMask=uiviewsautoresizingflexiblewidth | uiviewsautoresizingflexiblewhight代码>
在调整文本字段的大小后,应该可以这样做。这将在调整文本字段的superview大小后自动调整其大小。因此,一旦单元格准备好显示,文本字段将随之调整大小。我按您所说的那样放置,但再次使用subviewtofront时,它不会显示在单元格上,而使用addsubview时,文本“设置第一个…”不知道要做什么\u为什么不使用适当的UITableViewCell子类来维护正常的视图层次结构。
