I am working on my app to make compatible to iphone 5. In the following code, donebutton works for iphone 4, but when it comes to iphone5 it is not touchable! I dont know why?
float screenSizeHeight=[UIScreen mainScreen].bounds.size.height;
if(screenSizeHeight==568)
{
UIImageView *my_image_view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Plain_Background2.png"]];
[my_image_view setFrame:CGRectMake(0,20,320,568)];
[self.view addSubview:my_image_view];
[self.view sendSubviewToBack:my_image_view];
imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 20, 320, 460)];
[doneButtonOutlet setFrame:CGRectMake(124,470,72,28)];
}
if(screenSizeHeight==480)
{
UIImageView *my_image_view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Plain_Background.png"]];
[my_image_view setFrame:CGRectMake(0,20,320,480)];
[self.view addSubview:my_image_view];
[self.view sendSubviewToBack:my_image_view];
imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 20, 320, 400)];
[doneButtonOutlet setFrame:CGRectMake(124,432,72,28)];
}
This is because in iPhone 5 scrollView height is more and it is above your button.
So change origin y of UIButton.
imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 20, 320, 460)];
// Here imageScrollView bottom is at 480 pixel and doneButtonOutlet origin is at 470 so either small height of scrollview or change button origin y..
[doneButtonOutlet setFrame:CGRectMake(124,470,72,28)];
Hope it helps you.

My UIScrollView isn't scrolling. (I'm trying to get it to scroll horizontally) I'm setting the contentSize to be (960, 300). I have set the framesize of the UIScrollView to be width:320 height:300 in the storyboard.
I have a container view inside the scroll view that has a width of 960 points.
At 320 points, I have a subview that has a background color of brown. When I scroll, I can see the brown subview, but it bounces back when I let go of the drag.
This is my viewDidLoad method:
- (void)viewDidLoad
[super viewDidLoad];
self.scrollView.scrollEnabled = YES;
[self.scrollView setFrame:CGRectMake(0,0,320,300)];
self.scrollView.contentSize = CGSizeMake(960, 300);
UIView *subview1 = [[UIView alloc] initWithFrame:CGRectMake(320, 0, 320, 300)];
[subview1 setBackgroundColor:[UIColor brownColor]];
UIView *containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 960, 300)];
[containerView addSubview:subview1];
[self.scrollView addSubview:containerView];
}
Here is a sample code for create a scroll view programmatically:
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIScrollView* scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 300)];
scrollView.backgroundColor = [UIColor redColor];
scrollView.scrollEnabled = YES;
scrollView.contentSize = CGSizeMake(960, 300);
[self.view addSubview:scrollView];
UIView *subview1 = [[UIView alloc] initWithFrame:CGRectMake(320, 0, 320, 300)];
[subview1 setBackgroundColor:[UIColor brownColor]];
UIView *containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 960, 300)];
containerView.backgroundColor = [UIColor greenColor];
[containerView addSubview:subview1];
[scrollView addSubview:containerView];
So, there is no issue in your code, but something wrong with your storyboard configure.
I have a few thoughts about what you are trying to accomplish. I don't know how old is your code, but today we have many better ways to work with scrollview and they don't include setting up the intrinsic size or fame.
Well, despite my doubt about the objective of the code, I tried to run it here, using storyboard, a single view, a default configured scrollView and the experiment went well, your code actually works, I think maybe you have some problem with your scrollView. I know this will sound weird but did you checked if the scrollView has the property "Scrolling Enabled" checked?
If you can give me more information about this issue, I can help you.
I have an app that starts in Landscape mode and I have the following UIView that is created to go full screen.
- (void)loadSignupScreen {
CGFloat screenHeight = self.view.frame.size.height;
CGFloat screenWidth = self.view.frame.size.width;
self.signupContainer = [[UIView alloc] initWithFrame:self.view.bounds];
[self.signupContainer setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleBottomMargin|UIViewAutoresizingFlexibleLeftMargin|UIViewAutoresizingFlexibleRightMargin|UIViewAutoresizingFlexibleTopMargin];
UIImageView *bgImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, screenWidth, screenHeight)];
[bgImageView setBackgroundColor:[UIColor darkGrayColor]];
[bgImageView setAlpha:0.8];
[self.signupContainer addSubview:bgImageView];
[self.view addSubview:self.signupContainer];
}
The problem is that when I rotate the screen to portrait it isn't full screen instead it only seems to be about 3/4 the length of the screen. How can I make it fill the screen on rotate? I don't have a problem using the autosizing in IB just when it is programmed.
Thanks
You are assigning the wrong autoresizingMask to the signupContainer. It should just be flexible height and width.
[self.signupContainer setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight];
Also the UIImageView needs an autoresizingMask.
UIImageView *bgImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, screenWidth, screenHeight)];
[bgImageView setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight];
Im using the following codes to customize the navigationbar with an UIView. But why there is a gap in the left size of the navigationbar? ps. the gradient image is test.png.
Thanks in advance!
- (void)viewDidLoad
{
[super viewDidLoad];
// show image
UIImage *image = [UIImage imageNamed: #"test.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage: image];
[imageView setContentMode:UIViewContentModeScaleToFill];
imageView.frame = CGRectMake(0, 0, 320, 44);
// label
UILabel *tmpTitleLabel = [[UILabel alloc] initWithFrame:CGRectMake(110, 0, 100, 44)];
tmpTitleLabel.text = #"title";
tmpTitleLabel.textAlignment = UITextAlignmentCenter;
tmpTitleLabel.backgroundColor = [UIColor clearColor];
tmpTitleLabel.textColor = [UIColor whiteColor];
CGRect applicationFrame = CGRectMake(0, 0, 320, 44);
UIView * newView = [[UIView alloc] initWithFrame:applicationFrame];
[newView addSubview:imageView];
[newView addSubview:tmpTitleLabel];
self.navigationItem.titleView = newView;
}
Edit 1
Here is my test code and screen shot
- (void)viewDidLoad
{
[super viewDidLoad];
UIView * viewGreen = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
UIView * viewRed = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
[viewGreen setBackgroundColor:[UIColor greenColor]];
[viewRed setBackgroundColor:[UIColor redColor]];
self.navigationItem.titleView = viewRed;
[self.view addSubview:viewGreen];
}
your code is work fine.just check the image and transparency.
To add the line at last and check again
[self.view addSubview:newView];
problem is solved by the following code
[self.navigationBar insertSubview:imageView atIndex:1];
i have a problem with UIScrollView and UINavigationController(s) and iOS 4. The following code works fine with iOS 5:
////////////////////////////////////////////////////////////////////////////////////
/* Scroll View */
////////////////////////////////////////////////////////////////////////////////////
mScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 88, 1024, 668)];
mScrollView.contentSize = CGSizeMake(1850, 668);
////////////////////////////////////////////////////////////////////////////////////
// First View
////////////////////////////////////////////////////////////////////////////////////
UIImageView *imgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed: #"view_bg.png"]];
imgView.frame= CGRectMake(10, 50, 350, 510);
[mScrollView addSubview:imgView];
[imgView release];
mFirstView = [[[FirstView alloc] init] autorelease];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:mFirstView];
navigationController.navigationBar.tintColor = [UIColor colorWithRed:79.0/255 green:143.0/255 blue:0.0/255 alpha:1];
navigationController.view.frame = CGRectMake(25, 65, 320, 480);
[mScrollView addSubview:navigationController.view];
////////////////////////////////////////////////////////////////////////////////////
// Second View
////////////////////////////////////////////////////////////////////////////////////
UIImageView *imgView2 = [[UIImageView alloc] initWithImage:[UIImage imageNamed: #"view_bg.png"]];
imgView2.frame= CGRectMake(380, 50, 350, 510);
[mScrollView addSubview:imgView2];
[imgView2 release];
mSecondView = [[[SecondView alloc] init] autorelease];
UINavigationController *navigationController2 = [[UINavigationController alloc] initWithRootViewController:mSecondView];
navigationController2.navigationBar.tintColor = [UIColor colorWithRed:79.0/255 green:143.0/255 blue:0.0/255 alpha:1];
navigationController2.view.frame = CGRectMake(395, 65, 320, 480);
[mScrollView addSubview:navigationController2.view];
// finally add the scroll view to the parent view
[self.view addSubview:mScrollView];
All i do is, to add a ScrollView with 2 NavigationControllers (with a allocated root view controller) do the view. But using this code with iOS 4 does not show the right size of the ViewControllers added. The ViewControllers are the size of the whole iPad screen!!!!!
As i already said, it works on iOS 5! Even when i change the size of the views added manually it is not working, the added view always fills the whole iPad screen!! Any ideas to fix this?
Thank you in advance!
in your code you have the following
//first view you add mfirstview.view
[mScrollView addSubview:mFirstView.view];
//second view you add navigationController2.view
[mScrollView addSubview: navigationController2.view];
So i guess you have to change the first view code to do the following
[mScrollView addSubview: navigationController.view];
myscrollview = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0,self.view.frame.size.width, self.view.frame.size.height)];
myscrollview.delegate = self;
[self.view addSubview:myscrollview];
CGSize scrollViewContentSize = CGSizeMake(self.view.frame.size.width, self.view.frame.size.height+500);
[myscrollview setContentSize:scrollViewContentSize];
lblluckyno = [[UILabel alloc] initWithFrame:CGRectMake(20, 30, 200, 50)];
lblfirstmsg = [[UILabel alloc] initWithFrame:CGRectMake(15, 50, 295, 800)];
But I don't know My Firstmasg length.... after that lblfirstmsg I want to add second lblsecongmgs.... So how can I add?
After you set first label and set it content you can call [lblfirstmsg sizeToFit]; to fit frame to its content. Then you can add your second UIlabel next to the first one [[UILabel alloc] initWithFrame:CGRectMake(lblfirstmsg.frame.origin.x + lblfirstmsg.frame.size.width, lblfirstmsg.frame.origin.y, 200, 50)];
[myscrollview addSUbview:lblluckyno];
and same way add 2nd label.
This is your scroll view code.
myscrollview = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0,self.view.frame.size.width, self.view.frame.size.height)];
myscrollview.delegate = self;
[self.view addSubview:myscrollview];
[myscrollview setContentSize:CGSizeMake(self.view.frame.size.width,self.view.frame.size.height+500);];
After you set two label With CGRect and add in Scroll View
[myScrollView addSubView:lblluckyno];
......
Hello Mayur P Bhansali,
You can find the position and dimension of your first label like so:
lblluckyno = [[UILabel alloc] initWithFrame:CGRectMake(20, 30, 200, 50)];
UILabel *secondLabel = [[UILabel alloc] initWithFrame: CGRectMake(lblluckyno.frame.origin.x + lblluckyno.frame.size.width, 200, 100)];
Each UIView has a "frame" object and this frame object has a "origin" C structure and "size" C structure. Using labelName.frame.size.width gives you the width of a frame and labelName.frame.origin.x gives you the X coordinate of the frame.
You could access these properties like this too:
[labelName frame].size.width
[labelName frame].size.origin.x
lblluckyno = [[UILabel alloc] initWithFrame:CGRectMake(20, 30, 200, 50)];
lblfirstmsg = [[UILabel alloc] initWithFrame:CGRectMake(15, 50, 295, 800)];
[myscrollview addSUbview:lblluckyno];
[myscrollview addSUbview:lblfirstmsg];
