I am adding a cell to a UITableView which has a scrollview, the code I have in the cell is :
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 30, 320, 44)];
UIView *labelView = [[UIView alloc] initWithFrame:CGRectMake(4, 4, 80 * _labels.count, 44)];
for (NSUInteger i = 0; i < _labels.count; i++) {
NSString *aLabel = [_labels objectAtIndex:i];
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(i * 70, 3, 60, 30)];
button.tag = i;
[button setTitle:aLabel forState:UIControlStateNormal];
[button setBackgroundColor:[UIColor lightGrayColor]];
[labelView addSubview:button];
}
scrollView.contentSize = CGSizeMake(labelView.frame.size.width, labelView.frame.size.height);
[scrollView addSubview:labelView];
[self addSubview:scrollView];
However this does not scroll :(. If I have the same code segment outside the tableview and add this directly to the view, it works as expected. What am I missing?
Try [cell addSubview:scrollView];
Try adding the scrollView to the contentView of the UITableViewCell and maybe setting
self.contentView.userInteractionEnabled = NO
From the UITableViewCell reference doc
Discussion
The content view of a UITableViewCell object is the default superview for content displayed by the cell. If you want to customize cells by simply adding additional views, you should add them to the content view so they will be positioned appropriately as the cell transitions into and out of editing mode.

I have navigation bar with custom view on it. UIImageView and UILabel are subviews of titleView. And I add UITapGestureRecognizer to titleView to make it show another UIViewController when the user taps on it. When you tap on titleView other UIViewController opens. But when you click on back button in my titleView size of UIImageView changes. Here is the code
UIView *titleView = [[UIView alloc] initWithFrame: CGRectMake(0, 0, self.view.frame.size.width, 30)];
UILabel *title = [[UILabel alloc] initWithFrame: CGRectMake(0, 0, self.view.frame.size.width/2, 30)];
title.text = _groupName;
[title setTextColor:[self colorFromHexString:#"#474747"]];
[title setFont:[UIFont fontWithName:#"Roboto-Bold" size:16]];
[title setTextAlignment:NSTextAlignmentCenter];
[title setBackgroundColor:[UIColor clearColor]];
_imageView.frame = CGRectMake(0, 0, 30, 30);
_imageView.layer.cornerRadius = 15.0;
_imageView.layer.masksToBounds = YES;
_imageView.layer.borderColor = [UIColor lightGrayColor].CGColor;
_imageView.layer.borderWidth = 0.1;
_imageView.contentMode = UIViewContentModeScaleAspectFit;
title.frame = CGRectMake(title.frame.origin.x+20, title.frame.origin.y, self.view.frame.size.width/2, 30);
UITapGestureRecognizer *recognizer;
recognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:#selector(titleTapped:)];
titleView.userInteractionEnabled = YES;
[titleView addGestureRecognizer:recognizer];
[titleView addSubview:title];
[titleView setBackgroundColor:[UIColor clearColor]];
[titleView addSubview:_imageView];
self.navigationItem.titleView = titleView;
Here are the images where you can see the changes
I check your code Add clips to bounds and do not need to title frame two times.
_imageView.frame = CGRectMake(0, 0, 30, 30);
_imageView.layer.cornerRadius = 15.0;
_imageView.layer.masksToBounds = YES;
_imageView.clipsToBounds = true;
Rather than setting the frame of the views directly, you might try using Auto Layout; I suspect what's happening is that your custom view is getting re-layed-out after the back button, and it's reverting to the image view's instrinsicSize.
What you could do instead is turn off translatesAutoresizingMaskIntoConstraints on the subviews, and then add constraints to position them, and finally add width and height constraints to the image view.
Using Auto Layout is also recommended if you ever intend to internationalize your app -- if you set up your constraints correctly, then the translated title will fit and you won't have to ever play around with hardcoded values.
I have container view, where I add some image and button.
Container view is property of UIView.
I'll add my Container View to ScrollView like this:
#property (nonatomic,strong) UIView *containerView;
..
containerView = [[UIView alloc] init];
for (int i=0;i<5;i++) {
UIImageView *whiteBack = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 235-height, 385-height-height)];
whiteBack.center = CGPointMake(_scrollView.frame.size.width * i+_scrollView.frame.size.width/2, self.view.bounds.size.height/2-131+height);
whiteBack.backgroundColor = [UIColor darkGrayColor];
whiteBack.layer.cornerRadius = 3;
whiteBack.layer.masksToBounds = YES;
[containerView addSubview:whiteBack];
UIImageView *img = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 228-height, 340-height-height)];
img.center = CGPointMake(_scrollView.frame.size.width * i+_scrollView.frame.size.width/2, self.view.bounds.size.height/2-150+height);
img.image = [UIImage imageNamed:[NSString stringWithFormat:#"poster0%i.jpg",i+1]];
[containerView addSubview:img];
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeCustom];
infoButton.frame = CGRectMake(233, 0, 25, 25);
infoButton.center = CGPointMake(_scrollView.frame.size.width * i+_scrollView.frame.size.width/2-100, 325-height);
[infoButton addTarget:self action:#selector(flipImage:) forControlEvents:UIControlEventTouchUpInside];
infoButton.tag = i;
infoButton.backgroundColor = [UIColor clearColor];
[infoButton setImage:[UIImage imageNamed:#"upload-50"] forState:UIControlStateNormal];
[infoButton setTintColor:[UIColor whiteColor]];
[containerView addSubview:infoButton];
}
[self.scrollView addSubview:containerView];
///
- (void) flipImage :(id) sender {
NSLog(#"infoButton pressed:%i",[sender tag]);
}
but when I pressed button nothing happens!
Your container view has a zero frame (because you just did [[UIView alloc] init];). This means that it never receives any touches because you can never hit it. This goes for the subviews too.
The reason you see the subviews is that views, by default, do not clip drawing to their bounds.
To fix, set the frame of your container view to an appropriate size for the subviews you're adding.
I have 10 UIButtons stacked side to side in my app , and the total dimensions of the buttons are 640x96.
If I add these buttons directly to the UIScrollView, they register touch events and are scrollable.
But if I try to add them to a plain UIView, then add that UIView to the scrollview, they dont work.
This is my code:
- (void)viewDidLoad
{
[super viewDidLoad];
UIView *fview = [[UIView alloc] init];
fview.frame = CGRectMake(0, 0, 640, 96);
fview.backgroundColor = [UIColor blackColor];
[fview setUserInteractionEnabled:YES];
[_sv setUserInteractionEnabled:YES];
for (int i=0; i<10; i++)
{
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(64*i, 0, 64, 96);
[button setTitle:#"Click Me!" forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[fview addSubview:button];
}
[_sv addSubview:fview];
_sv.contentSize = CGSizeMake(640, 96);
}
-(void)buttonClicked:(id)sender {
NSLog(#"Clicked!");
}
While I was writing the question I fixed the problem :D
All I had to do was to set the frame of the UIView before I set the scrollview's contentsize.
In my case:
[_sv addSubview:fview];
fview.frame = CGRectMake(0, 0, 640, 96); // Added line
_sv.contentSize = CGSizeMake(640, 96);
Hope this helps!
I have a UITableViewController that has a tableView. To this tableView, I would like to add both a label as well as a button but unfortunately, I am only able to add one or the other.
Here is my code that I am working with:
- (void) viewDidLoad {
[super viewDidLoad];
selectAllButton = [UIButton buttonWithType:UIButtonTypeCustom];
[selectAllButton setFrame:CGRectMake(280, 0, 25, 25)];
[selectAllButton setImage:[UIImage imageNamed:#"CheckBox1.png"] forState:UIControlStateSelected];
[selectAllButton setImage:[UIImage imageNamed:#"CheckBox2.png"] forState:UIControlStateNormal];
[selectAllButton setUserInteractionEnabled:YES];
[selectAllButton addTarget:self action:#selector(buttonTouched:) forControlEvents:UIControlEventTouchUpInside];
selectAllLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 300, 40)];
[selectAllLabel setTextColor:[UIColor blackColor]];
[selectAllLabel setBackgroundColor:[UIColor clearColor]];
[selectAllLabel setText:#"Select All"];
self.tableView.tableHeaderView = selectAllButton;
self.tableView.tableHeaderView = selectAllLabel;
}
When I run the above method, I am only able to see my label which tells me it is replacing the button. Is there a way for me to get both elements to appear in the tableheaderview?
Create a UIView, add your button & label to it as subviews, than make that view your self.tableview.tableHeaderView
...your code
UIView *headerView = [UIView alloc] initWithFrame:CGRectMake(0, 0, self.tableView.frame.size.width, selectAllButton.frame.size.height + selectAllLabel.frame.size.height)];
[headerView addSubview:selectAllButton];
[headerView selectAllLabel];
self.tableView.tableHeaderView = headerView;
When you init your button & label be sure to change the frame as they will be based on the UIView
Since tableHeaderView is an UIView, try to add it with addSubview:(UIView*) or create an UIView and add that as your tableHeaderView.
How to insert four tableview in a scrollview by pagination.i know how to do this ,but i need a image view as first page and then tableview as second,third and forth page.
Thankz in advance
_scroll=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 55, 1000, 460)];
_scroll.backgroundColor=[UIColor clearColor];
_scroll.pagingEnabled=YES;
_scroll.contentSize = CGSizeMake(1000*5, 460);
[_scroll setBackgroundColor:[UIColor lightGrayColor]];
CGFloat x=0;
for(int i=1;i<6;i++)
{
UITableView *table = [[UITableView alloc]initWithFrame:CGRectMake(x+10, 10, 750, 440) style:UITableViewStylePlain];
[table setBackgroundColor:[UIColor whiteColor]];
table.rowHeight = 120;
table.separatorColor = [UIColor grayColor];
table.delegate=self;
//table.dataSource=self;
[_scroll addSubview:table];
[table release];
x+=1000;
}
[self.view addSubview:_scroll];
_scroll.showsHorizontalScrollIndicator=NO;
[_scroll release];
Ignoring the recommendation that UITableViews are not embedded inside scroll views as they are scrollviews in themself. So dont do this (not a joke).
You add the imageview with addSubview: just like the tableviews you want add. They are all UIViews and are all treated the same way.
So for a hypothetical scrollview with size (100,100) and imageview/tableviews of size (100,100)
imageview.frame = CGRectMake(0,0,100,100);
[scrollview addSubview:imageview];
tableview1.frame = CGRectMake(100,0,100,100);
[scrollview addSubview:tableview1];
tableview2.frame = CGRectMake(200,0,100,100);
[scrollview addSubview:tableview2];
tableview3.frame = CGRectMake(300,0,100,100);
[scrollview addSubview:tableview3];
scrollview.contentSize = CGSizeMake(400,100);
scrollview.pagingEnabled = YES;
