How to set CustomFrame on iCarousel in iphone? - iphone

I want to set the frame of iCarousel according to my need. First it shows in the middle of the simulator but i tried my code now it is showing at the top of the simulator.
I am trying this code:
// Try to add custom view for setting height and width of iCarousel
UIView *Carasouel_Customview = [[UIView alloc]initWithFrame:CGRectMake(10, -245, 768, 245)];
[self.view addSubview:Carasouel_Customview];
// Initialize and configure the carousel
//carousel = [[iCarousel alloc] initWithFrame:self.view.bounds];
carousel = [[iCarousel alloc] initWithFrame:Carasouel_Customview.bounds];
//carousel = [[iCarousel alloc] initWithFrame:CGRectMake(20, 200, 179, 245)];
carousel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
carousel.type = iCarouselTypeRotary;
carousel.dataSource = self;
carousel.delegate = self;
[self.view addSubview:carousel];
Any hints from experts would be very welcome.

self.carousel = [[iCarousel alloc]initWithFrame:CGRectMake(0.0, 0.0, 200.0, 150.0)];
self.carousel.delegate = self;
self.carousel.dataSource = self;
self.carousel.type = iCarouselTypeLinear;
self.carousel.clipsToBounds = YES; //This is main point
[self.view addSubview:self.carousel];
When we set customFrame to iCarousel we get its width of fullScreen. So just set its clipsToBounds property YES :)

You're setting y-coordinate -245 to Carasouel_Customview and then setting carousel.frame with Carasouel_Customview.bounds - here y-coordinate is 0.
You are adding carousel to self.view, not Carasouel_Customview - so what do you expect?
Solution:
Add carousel as subview to Carasouel_Customview or set carousel.frame with custom values.

iOS7 View moves under status/nav bars when loadView called again

I have a View Controller that creates its view programatically through the loadView method. The purpose of the view is to display a data models contents. When the view loads it is aligned correctly under the status and navigation bar.
But at a later point I present another view modally to allow the user to select a different data model to populate the view. This causes the the loadView to get called again and re-create the required UI for the new data model. The problem is that the view's contents now appear under the status and navigation bars!
Please note that I am not using auto-layout due to having to support iOS4 :( Also if I include the extendedLayout fix - it does fix the problem but only after the modal's dismiss animation completes leaving a jump down effect. My code below, thanks for any help.
- (void)loadView {
CGRect frame = CGRectMake(0, 0, [Constants ScreenWidth], [Constants ScreenHeight] - StatusBarHeight - ToolbarHeight);
self.view = [[UIView alloc] initWithFrame:frame];
self.view.autoresizingMask = UIViewAutoresizingFlexibleHeight;
self.view.autoresizesSubviews = YES;
self.view.backgroundColor = [Constants categoriesScreenBackgroundColor];
CGRect scrollFrame = CGRectMake(0, 0, [Constants ScreenWidth], [Constants ScreenHeight] - StatusBarHeight - ToolbarHeight - ToolbarHeight);
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:scrollFrame];
scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight |
UIViewAutoresizingFlexibleBottomMargin |
UIViewAutoresizingFlexibleTopMargin;
[self.view addSubview:scrollView];
_toolbarViewController = [self createToolbarViewController];
[self.view addSubview:_toolbarViewController.view];
_toolbarViewController.productInfoWorkflowState = _productInfoWorkflowState;
UIView *containerView = [[UIView alloc] initWithFrame:scrollView.frame];
containerView.backgroundColor = [UIColor clearColor];
_headerViewController = [self createHeaderViewController];
[containerView addSubview:_headerViewController.view];
_menuViewController = [[ProductInfoMenuViewController alloc] initWithBatch:[self batchData]];
_menuViewController.delegate = self;
[containerView addSubview:_menuViewController.view];
CGRect categoriesFrame = _menuViewController.view.frame;
categoriesFrame.origin.y = _headerViewController.view.frame.size.height;
_menuViewController.view.frame = categoriesFrame;
CGRect viewFrame = containerView.frame;
viewFrame.size.height = _headerViewController.view.frame.size.height + _menuViewController.view.frame.size.height;
containerView.frame = viewFrame;
[scrollView addSubview:containerView];
scrollView.contentSize = containerView.frame.size;
_starViewController = [[StarViewController alloc] initForProduct:_productData With:[StarredItems new]];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:_starViewController.view];
}
Screen layout after first load:
Screen layout after second load:
With Leo's suggested fix, the scrollView is correct BUT the toolbar at the bottom now appears incorrectly. Code I used (placed after the toolbar creation code above):
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"7.0")) {
self.automaticallyAdjustsScrollViewInsets = NO;
scrollView.scrollIndicatorInsets = UIEdgeInsetsMake(64.0f, 0.0f, 0.0f, 0.0f);
scrollView.contentInset = UIEdgeInsetsMake(64.0f, 0.0f, 0.0f, 0.0f);
}
Results:
Add following code its work for me for same issue, may be its help you
/* ios 7 Change */
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7)
{
self.edgesForExtendedLayout = UIRectEdgeNone;
self.automaticallyAdjustsScrollViewInsets = NO;
}
Does this only happen on iOS 7?
Give this a try:
self.navigationController.navigationBar.translucent = NO;
Try following:
Toolbar.autoresizingMask = UIViewAutoresizingFlexibleTopMargin;
try this
CGRect frame = CGRectMake(0, StatusBarHeight, [Constants ScreenWidth], [Constants ScreenHeight] - StatusBarHeight - ToolbarHeight);
self.view = [[UIView alloc] initWithFrame:frame];
self.view.autoresizingMask = UIViewAutoresizingFlexibleHeight;
self.view.autoresizesSubviews = YES;
self.view.backgroundColor = [Constants categoriesScreenBackgroundColor];
CGRect scrollFrame = CGRectMake(0, StatusBarHeight, [Constants ScreenWidth], [Constants ScreenHeight] - StatusBarHeight - ToolbarHeight - ToolbarHeight);
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:scrollFrame];
scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight |
UIViewAutoresizingFlexibleBottomMargin |
UIViewAutoresizingFlexibleTopMargin;
[self.view addSubview:scrollView];
I think the problem is due to incorrect automatic set of content insets of the scrollview.
Try the following. In your loadView, set self.automaticallyAdjustsScrollViewInsets to NO (only if NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1). Now, set the contentInset and scrollIndicatorInsets to the correct values depending on OS version:
scrollview.contentInset = scrollview.scrollIndicatorInsets = UIEdgeInsetMake(NSFoundationVersionNumber <= NSFoundationVersionNumber_iOS_6_1 ? 0 : 64, 0, 0, 0);
My problem was solved unmarking the check "Adjust Scroll View Insets" in the View Controller (using Storyboards).

UIPickerView Height customisation

Need to display 4 UIPickerView in ViewController.
How can i customise height?
Minimum height we can given is 162.
Can i give 100 height for each UIPickerView?
Is there any framework or example available?
Try this:
UIPickerView *picker = [[UIPickerView alloc] initWithFrame: CGRectZero];
picker.showsSelectionIndicator = YES;
picker.autoresizingMask = UIViewAutoresizingFlexibleWidth;
CGSize ps = [picker sizeThatFits: CGSizeZero];
picker.frame = CGRectMake(0.0, 0.0, ps.width, ps.height + 100);
Try with following code, it may be work in you case:
self.MyPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 0, 320, 100)];
For Other tips check This Answer
UIPicker sizing in landscape mode
For UIPickerView there are only three Height : 162,180,216. You can use CGAffineTransformMakeTranslation and CGAffineTransformMakeScale for properly fit to picker.
CGAffineTransform t;
CGAffineTransform s;
CGAffineTransform u;
UIPickerView *pickerview;
t = CGAffineTransformMakeTranslation (0, pickerview.bounds.size.height);
s = CGAffineTransformMakeScale (1.0,0.5);
u = CGAffineTransformMakeTranslation (0 ,pickerview.bounds.size.height);
pickerview.transform = CGAffineTransformConcat (t, CGAffineTransformConcat(s,u));
Here the above code changes the height of picker view.
If you don't mind clipping the ends, you can embed it inside of a smaller view, with clipping enabled.

How to add View below other view in ViewController in iOS?

In my app i am creating view controller with mixed of UILabel and UITextview which want to be scrollable because the text are dynamic and also exceeds vertical screen size.
I am currently having Scrollview which has subviews as below. Views are created in Xcode 4.3 Storyboard.
UILabel1(Say Heading)
UITextView1(Dynamic text which can be any size)
UILabel2(Second Heading)
UITextView2(Dynamic text which can be any size)
and so on.
The problem is
When the UITextView1 has more content then it overlaps with UILabel2 which i don't want.
I would like to have UILabel1 on top of scrollView and UITextView1 below the UILabel1. UILabel2 below UITextView1 and so on.
What i have to do to achieve this?
EDIT
In Storyboard

In Simulator

Thanks for your help guys. Much appreciated.
Code
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
[scrollView setScrollEnabled:YES];
[self.view addSubview:cockTailNameLabel];
[self.view insertSubview:txtIngredients belowSubview:cockTailNameLabel];
[self.view insertSubview:scrollView belowSubview:cockTailNameLabel];
//[scrollView]
[self.cockTailNameLabel setText:self.passcockTailName];

[scrollView setContentSize:CGSizeMake(320, 1000)];
NSLog(#"RecipeName :%# ",passcockTailName);
}
In Storyboard or IB you can rearrange them freely.
In code you do - (void)insertSubview:(UIView *)view belowSubview:(UIView *)siblingSubview.
In code (in viewDidLoad):
UIScrollView *scroll =[[UIScrollView alloc] initWithFrame:CGrectMake(0,0 320, 480)];
[self.view addSubview:scroll];
// code to init your UI object
UILabel *uilabel1 = [[UIlabel alloc] initWithFrame:CGrectMake(10,10, 100, 40)]; // example
uilabel1.font = [UIFont systemFontOfSize:10];
uilabel1.text = #"UILabel1";
uilabel1.backgroundColor = [UIColor clearColor];
//
//
UILabel *uilabel2 = [[UIlabel alloc] initWithFrame:CGrectMake(10, 10 + 10 + uilabel1.frame.origin.y, 100, 40)]; // example
uilabel2.font = [UIFont systemFontOfSize:10];
uilabel2.text = #"UILabel2";
uilabel2.backgroundColor = [UIColor clearColor];
//
//
[scroll addSubview:uilabel1];
[uilabel1 releale];
[scroll addSubview:uilabel2];
[uilabel2 releale];
//
//
// in end
float offset = 10.0 * 2; // offset between uiobjects, N - number of objects
scroll.contentSize = CGSizeMake (0, 0, uilabel1.frame.size.height + uilabel2.frame.size.height + offset, 320);
Note that you may set frame (and other properties) of yours uiobjects and adds it in order to descend.
You can tell next view to start from the end of the first view like so:
startYOfNextView = firstView.frame.origin.y position + firstView.frame.size.height;
Do the same for the rest of the other view. If your view has variable text length, you may need to precaculate the height of the string based on a specific font e.g.:
CGSize maxSize = CGSizeMake(widthOfView, 9999999);
CGSize expectedSize = CGSizeMake(stringVar sizeWithFont:[UIFont fontWithName:#"Arial"] withMaxSize:maxSize lineBreakMode:UILineBreakModeWordWrap);
then tell your dynamic view to use the height of expectedSize variable like so:
myDynamicView = [[UILabel alloc] initWithFrame:CGRectMake(..., expectedSize.height)];
Your issue is labels are coming on top of the textview (Overlapped), right?
In This case, you are modifying the height of the textview dynamically. If its just for display purpose you can set the text to a UILabel with numberOfLines = 0 instead of UITextview; As its added to scrollview adding a label will be fine.
Also you need to modify the origin.y of the remaining views so that it will be properly aligned. ie, secondView.origin.y = firstView.origin.y + firstView.size.height + offset. Likewise modify the origin of the remaining views wrt the just above view. So that its origin will lie outside the previous view frame.
In my case I had to project it over the parent view, so remember there is also something,
- (void)insertSubview:(UIView *)view aboveSubview:(UIView *)siblingSubview
I think adding a transparent UI button is the fastest solution. You could add it once and then show / hide whenever you need to disable all views below the current one (assuming the "current" view, say a popup, was added last to your superview).
Declare an instance variable UIButton* _parentDisablingOverlay; in your popup view, then add this in its init or layoutSubviews method:
_parentDisablingOverlay = [[UIButton alloc] initWithFrame:CGRectMake(0,0, self.superview.frame.size.width, self.superview.frame.size.height)];
[self.superview insertSubview:_parentDisablingOverlay belowSubview:self];
_parentDisablingOverlay.hidden = true;
Later on, when you want to show the popup and disable everything below:
- (void) open {
self.hidden = false;
_parentDisablingOverlay.hidden = false;
}
Similarly to close and re-enable everything:
- (void) close {
self.hidden = true;
_parentDisablingOverlay.hidden = true;
}

view inside scrollView it is not moving

I have a UIScrollView of size 320x412 and inside it an UIView of size 280x277.But I tried for hours to make that View move up and down when I drag it.If I replace the UIView with a TextView it is working...I can drag the TextView up and down inside the UIScrollView...but with the View it is not working.
This is how my xib file looks like.The black one is the View I want to make it move inside the UIScrolView.ANy idea why is this not working?
EDIT: I did this
scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
scrollView.contentSize = CGSizeMake(320,480);
scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
scrollView.bounces = YES;
scrollView.bouncesZoom = YES;
scrollView.scrollEnabled = YES;
scrollView.minimumZoomScale = 0.5;
scrollView.maximumZoomScale = 5.0;
scrollView.delegate = self;
//myView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
[scrollView addSubview:myView];
[myView release];
And still not working!
You need to set the content size of scrollview greater then scrollview frame height to make the scrollview to scroll vertically. You scrollview height is 412.
Set content size, scrollview.contentSize = CGSizeMake(320, 430);
ALWAYS resize scrollview.contentSize .....
and not the scrollview.frame :===////
good luck! :=)

UIPickerView not appearing until touch occurs

I'm programatically adding two custom UIPickerViews to another view (MainView). They work just fine but they are not visible until a touch event occurs in any part of the MainView. I've checked the class references for UIPickerView and UIView but haven't found anything that manages to "refresh" the view, unless I'm missing something obvious?
Here's my drawRect method in MainView.m. I've tried doing the same thing in viewDidLoad but with no success. Could the custom rotations/transforms etc have something to do with it?
- (void)drawRect:(CGRect)rect {
CGRect pickerFrame = CGRectMake(50, -32, 30, 180);
m_picker1 = [[UIPickerView alloc] initWithFrame:pickerFrame];
m_picker1.delegate = self;
m_picker1.tag = k_ptag1;
m_picker1.showsSelectionIndicator =YES;
m_picker1.backgroundColor = [UIColor clearColor];
CGAffineTransform rotate = CGAffineTransformMakeRotation(3.14/2);
rotate = CGAffineTransformScale(rotate, 0.075, 0.85);
[m_picker1 setTransform:rotate];
[self addSubview:m_picker1];
pickerFrame = CGRectMake(50, 67, 30, 180);
m_picker2 = [[UIPickerView alloc] initWithFrame:pickerFrame];
m_picker2.delegate = self;
m_picker2.tag = k_ptag2;
m_picker2.showsSelectionIndicator =YES;
m_picker2.backgroundColor = [UIColor clearColor];
rotate = CGAffineTransformMakeRotation(3.14/2);
rotate = CGAffineTransformScale(rotate, 0.075, 0.85);
[m_picker2 setTransform:rotate];
[self addSubview:m_picker2];
}
You add subviews in a view's controller, not the view itself. I would suggest familiarising yourself with the MVC design pattern.
drawRect is only supposed to be used for the actual drawing of the view itself, not subviews.
