I have several sub views added to a UIScrollView in the main view controller. Each sub view's view controller has its own tap recognizer. The problem is, only tapping in the starting area on the screen is recognised. After scrolling the view and tapping beyond the starting area, the tapping handler will no longer be called.
This SO post UIButton in non-visible area of UIScrollView seems to be relevant but its solution description wasn't really clear to me...
A simple report project could be found at: dropbox link
Thanks.
Please check your contentview size or setbackground color for scrollview and contentview. Contenview size is not increasing i think.
I have downloaded your project and see that the
SSubViewController *pvc = [SSubViewController controllerWithSubViewID:0];
pvc frame is out of bound
SSubViewController *pvc = [SSubViewController controllerWithSubViewID:0];
[self.scrollView addSubview:pvc.view];
[self addChildViewController:pvc];
[pvc.view setBackgroundColor:[UIColor grayColor]];
[pvc.view setFrame:CGRectMake(0, 0, 400, 200)];
[pvc didMoveToParentViewController:self];
SSubViewController *pvc1 = [SSubViewController controllerWithSubViewID:1];
[self.scrollView addSubview:pvc1.view];
[pvc1.view setBackgroundColor:[UIColor yellowColor]];
[self addChildViewController:pvc1];
[pvc1 didMoveToParentViewController:self];
[pvc1.view setFrame:CGRectMake(0, 400, 400, 200)];
Now see the Colours
As you can see Gray color, and Yellow color frame

I'm trying to implement a ScrollView, but when I put a View inside, the View looks good in the preview but it's not the same when I run the application:
http://i.stack.imgur.com/ZZfEg.jpg
And I don't know how to resize a text of the width of the view.
Without the ScrollView I can do a good structured view but when I use ScrollView I cannot get a good view, how to do ?
Code here: http://pastebin.com/LN5FySku
I think this task is very easy if you use code rather than storyboard.
Use this code..
You can do this in Storyboard as well but i prefer using code for such tasks. Hope that helped.
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 520)]; // little less than 568 to accommodate the tabBar
[scrollView setContentSize:CGSizeMake(320, 1500)];
UIView *largeView = [[UIView alloc] initWithFrame:CGRectMake(10, 10, 320, 100)];
[scrollView addSubview:largeView];
[self.view addSubview:scrollView];
for further more information check this link.
My problem is solved, the reasons:
UIImageView: I think my view have lost the images when i did a copy past of the view, so click on your UIImageView and set the image field.
UILabel: For the cropped text you have to create the Equal Width Constraint between the ContentView and the View, select the ContentView on the view hierarchy and Control + Drag to the View – you should get a pop-up that gives you the “Equal Widths” option.
I have three views : topView, middleView, bottomView.
When I clicked the button in the topView, I want to insert alpha view between topView and middleView.
but middleView and bottomView is already located by calling method [self.view addsubView:] at viewDidLoad.
So I have to change middleView and bottomView below the alpha view...
So I called method 'setFrame', but already added views didn't move to where i want to put them.
So I have to call method 'removeFromSuperView' but there is a big problem that middleView and bottomView are the master views that has multiple subviews into them...
I don't know how to solve this problem, please help me!
! middleView and bottomView, they just need to go down , moving issue is simple.
****UPDATE
My code about the issue is below :
authCodeView is alphaView
authCodeView = [[UIView alloc] initWithFrame:CGRectMake(0, topView.frame.size.height + 8, [UIScreen mainScreen].bounds.size.width, topView.frame.size.height)];
[authCodeView setBackgroundColor:[UIColor whiteColor]];
authCodeField = [[UITextField alloc] initWithFrame:CGRectMake(30, 0, authCodeView.frame.size.width - 30, authCodeView.frame.size.height)];
authCodeField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:#"인증번호 입력" attributes:#{NSForegroundColorAttributeName:tempGray}];
[authCodeView addSubview:authCodeField];
NSLog(#"%f",authCodeView.frame.origin.y+authCodeView.frame.size.height + 8);
[middleView setFrame:CGRectMake(100, authCodeView.frame.origin.y+authCodeView.frame.size.height + 8, [UIScreen mainScreen].bounds.size.width, 308.0f)];
[bottomView setFrame:CGRectMake(0, middleView.frame.origin.y+middleView.frame.size.height+8, [UIScreen mainScreen].bounds.size.width, bottomView.frame.size.height)];
[self.view addSubview:authCodeView];
[self.view addSubview:middleView];
[self.view addSubview:bottomView];
So I called method 'setFrame', but already added views didn't move to where i want to put them.
Then you passed the wrong rectangle to -setFrame:. That method changes the frame of the view, i.e. it's location and size in the coordinate system of its superview.
So I have to call method 'removeFromSuperView' but there is a big problem that middleView and bottomView are the master views that has multiple subviews
You don't need to remove a view just to change its position. You'd only need to remove it if you want to add it to some other view instead, or if you no longer want it in the superview at all. That said, it's not a problem if a view like middleView has subviews -- those will go along with middleView if you remove it from its superview, or if you change middleView's position, etc.
I don't know how to solve this problem, please help me!
When asking for help, you really need to post code that reproduces the problem you're trying to solve.
For example:
there is a tableView, when it is pulled down, the back view display. the effect is like this:
I tried like this but not working:
[self.view addSubview:logoView];
[self.view addSubview:tableView];
You have to
add your logo image view below the table view in xib.
set table view background color to clear color
Set logo image hidden.
in - (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate or check for your self which delegate is best suited. set the logo image hidden to NO
You set the tableView background as your logoview. Keep your UITableviewCell as what color you want.
I'm not sure if i recognize your problem but i think you want something like this:
you'll have to use:
[self.view insertSubview:aboveSubview: ];
[self.view insertSubview:belowSubview: ];
not
[self.view addSubview: ];
You can achieve the same as the example image above by adding the view with a negative y offset.
UIView *header = [[UIView alloc] initWithFrame: CGRectMake(0.0f, 0.0f - self.view.bounds.size.height, self.view.bounds.size.width, self.view.bounds.size.height)];
header.backgroundColor = [UIColor lightGrayColor];
[self.tableView addSubview:header];
However if you have content in this view, such as a logo, it will appear to be pulled down from the top, rather than behind the table, I don't know if this is the effect you want or not.
got a bit of a small problem here. I've been following this tutorial which creates an automatic scrolling slideshow using uiscrollview. This piece of code is used in my viewdidload -
UIScrollView *scr=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 120, 320, 180)];
scr.tag = 1;
scr.autoresizingMask=UIViewAutoresizingNone;
[self.view addSubview:scr];
[self setupScrollView:scr];
UIPageControl *pgCtr = [[UIPageControl alloc] initWithFrame:CGRectMake(0, 280, 320, 60)];
[pgCtr setTag:12];
pgCtr.numberOfPages=10;
pgCtr.autoresizingMask=UIViewAutoresizingNone;
[self.view addSubview:pgCtr];
As you can see a small uiscrollview is created programatically which is 320x180. It works perfectly except for the fact that my UI has another uiscrollview which takes up the whole ui, which is around 320x700. I need to embed this programatically created scrollview into it, any ideas? Or alternatively I need to create my own scrollview using storyboards and link it across using code, but have no idea how I would go about this.
Any ideas would be much appreciated.
You have to embed the scroll view inside the scroll view not the main view
[self.scrollView addSubview:scr];
I have a subview in my navigation bar. I try to add it by this way:
UIView *customView =
[[UIView alloc] initWithFrame:
CGRectMake(0, 0, image.size.width + label.frame.size.width, 44)];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
[customView addSubview:imageView];
[customView addSubview:label];
[self.navigationController.navigationBar addSubview:customView];
However, when I try to push the navigation bar, the customView stays in the place, not animating following the sliding navigation bar. How can I achieve the animated subview? Is it even possible? Thanks!
you should not add subview in that way
you have tospecify your view location in the left , right or title view
self.navigationItem.titleView = YOURVIEW;
or choose another location left or right items in this way the the title view will added to the current view if you want to remove it just set it to nil in the place you want and reload it subviews again,
self.navigationItem.titleView = nil;
As you are using
[self.navigationController.navigationBar addSubview:customView];
that means the navigation bar you have create is in App delegate and is common for all the viewControllers in your project,that is why once you add a view on to it you see it on every view you have. Remove your sub-view in
-(void)viewWillDisappear:(BOOL)animated{
[Your subview remove fromSuperView];
[super viewWillDisappear:YES];
}
and add that subview in
-(void)viewWillAppear:(BOOL)animated{
[self.navigationController.navigationBar addSubview:Your subview];
[super viewWillAppear:YES];
}
this will add the subview in that particular view only and remove it as soon as that view is popped or pushed.The code given is not correct to the syntax please give a check on that.
