Add UIControl programmatically - ios

Question

I try a adding UITableView into scrollview programmatically. I have set anchors and datasource, delegate. You can see in codes. But I can't. I put a breakpoint and everything run. But I can't see in my scrollview.
UITableView *tableView = [[UITableView alloc] init];
tableView.rowHeight = 130;
tableView.translatesAutoresizingMaskIntoConstraints = false;
tableView.delegate = self;
tableView.dataSource = self;
tableView.backgroundColor = [UIColor clearColor];
[self.scrollView addSubview:tableView];
[tableView.leftAnchor constraintEqualToAnchor:self.scrollView.leftAnchor constant:8].active = YES;
[tableView.rightAnchor constraintEqualToAnchor:self.scrollView.rightAnchor constant:8].active = YES;
[tableView.topAnchor constraintEqualToAnchor:self.viewShareBasketExtra.topAnchor constant:8].active = YES;
[tableView reloadData];
This codes are working:
UILabel *lblPrice = [[UILabel alloc] init];
[lblPrice setFont:[UIFont fontWithName:#"HelveticaNeue" size:14]];
lblPrice.translatesAutoresizingMaskIntoConstraints = false;
[lblPrice setTextAlignment:NSTextAlignmentCenter];
lblPrice.text = [NSString stringWithFormat:#"%.2f TL",[_productModel Price]];
[self.priceView addSubview:lblPrice];
[lblPrice.leftAnchor constraintEqualToAnchor:self.priceView.leftAnchor constant:8].active = YES;
[lblPrice.rightAnchor constraintEqualToAnchor:self.priceView.rightAnchor constant:8].active = YES;
[lblPrice.centerXAnchor constraintEqualToAnchor:self.priceView.centerXAnchor].active = YES;
[lblPrice.centerYAnchor constraintEqualToAnchor:self.priceView.centerYAnchor].active = YES;
[self getComments];
But that codes are not working :
UITableView *tableView = [[UITableView alloc]init];
tableView.rowHeight = 130;
tableView.translatesAutoresizingMaskIntoConstraints = false;
tableView.delegate = self;
tableView.dataSource = self;
tableView.backgroundColor = [UIColor clearColor];
[self.scrollView addSubview:tableView];
[tableView.leftAnchor constraintEqualToAnchor:self.scrollView.leftAnchor constant:8].active = YES;
[tableView.rightAnchor constraintEqualToAnchor:self.scrollView.rightAnchor constant:8].active = YES;
[tableView.topAnchor constraintEqualToAnchor:self.webView.topAnchor constant:8].active = YES;
My delegate methods :
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if(commentsArray!=nil){
return [commentsArray count];
}else
{
return 0;
}
}
And I am using custom table cell:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *identity = #"CommentTableViewCell";
CommentTableViewCell *cell = (CommentTableViewCell *)[tableView dequeueReusableCellWithIdentifier:identity];
if(cell == nil){
#try {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"CommentTableViewCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
#catch (NSException *exception) {
NSLog(#"Err:%#", exception.reason);
}
#finally {
}
}

Answer 1

in your header file .h add the next code:
<UITableViewDelegate,UITableViewDataSource>
For example in UIVIewController Class
#interface ViewController : UIViewController<UITableViewDelegate,UITableViewDataSource>
and this is all for you header file now got to .m and implement de nextlines:
this is for height:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{return 40.0f}
and after for this you add in your scrollview
scrollview.addSubview(yourTableView)

didLoad, now UILabel *lblPrice = [[UILabel alloc] init]; working but _webView = [[UIWebView alloc] init]; not working.
- (void)viewDidLoad {
[super viewDidLoad];
self.leftLabel = 0;
self.topLabel = 0;
self.statusWeb = 0;
[self.scrollView setBackgroundColor:[UIColor redColor]];
[lblFavoritesComment setText:[NSString stringWithFormat:#"%ld",(long)[_productModel totalFavorite]]];
[lblCommentCount setText:[NSString stringWithFormat:#"%ld",(long)[_productModel totalComments]]];
[lblProductName setText:[_productModel ProductName]];
lblDescription.lineBreakMode = UILineBreakModeWordWrap;
lblDescription.numberOfLines = 0;
[lblDescription setText:[_productModel Description]];
[lblDescription sizeToFit];
if([_productModel serviceHour] == 0){
NSString *serviceMinStr = [NSString stringWithFormat:#"%ld dk.",(long)[_productModel serviceMin]];
[lblTime setText:serviceMinStr];
}
if([_productModel serviceHour ] == 0 && [_productModel serviceMin] == 0){
[lblTime setText:#""];
}
if(![_productModel.Recipe isKindOfClass:[NSNull class]]){
if(![_productModel.Recipe isEqualToString:#"NULL"] || _productModel.Recipe.length>0){
self->statusWeb = 1;
_webView = [[UIWebView alloc] init];
_webView.translatesAutoresizingMaskIntoConstraints = false;
_webView.frame = CGRectMake(0,0,200, 300);
NSMutableString *html = [NSMutableString stringWithString: #"<html><head><title></title></head><body style=\"background:transparent;\">"];
[html appendString:[_productModel Recipe]];
[html appendString:#"</body></html>"];
[_webView setBackgroundColor:[UIColor blueColor]];
[_webView loadHTMLString:[html description] baseURL:nil];
[self.viewWebView addSubview:_webView];
