Multiple instance UIView only load xib file in the first instance - ios

I'm working on as slideshow with some CustomUIView showed in a UIScrollView and it works good. But i have a custom UIView to show the content of each news. My slide works goods , but the XIB file of my custom view is loaded only for the first one and other customview are empty.
Here is my code :
my ViewController.m
- (void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:YES];
int nbrNews = _sharedDataManager.rssfeeds.count;
_sliderView.contentSize = CGSizeMake(self.view.frame.size.width*nbrNews, self.view.frame.size.height);
self.pageControl.currentPage = 0;
self.pageControl.numberOfPages = nbrNews;
for (int i = 0; i< nbrNews; i++) {
NewsView *newsView = [[NewsView alloc] initWithFrame:CGRectMake(i*self.view.frame.size.width, 0, self.view.frame.size.width, self.view.frame.size.height)];
NSDictionary *news = [_sharedDataManager.rssfeeds objectAtIndex:i];
newsView.titleLabel.text = [news objectForKey:#"title"];
[_sliderView addSubview:newsView];
}
}
CustomView.h
#import <UIKit/UIKit.h>
#interface NewsView : UIView
#property (weak, nonatomic) IBOutlet UILabel *titleLabel;
#end
CustomView.m
#import "NewsView.h"
#implementation NewsView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
self = [[[NSBundle mainBundle] loadNibNamed:#"OneNewsView" owner:self options:nil] objectAtIndex:0];
}
return self;
}
#end
here the result :
EDITED : i change the color of the view in my custom view. and we can see that only the first one is realy loaded with xib file. and i dont know why !!!! can you help me?

i solve my problem by adding :
self.frame = frame;
to my customView.m initWithFrame

Reuse xib in different screens

I have 4 screens that have one almost the same view:
And one screen have the same view but with slightly different UI:
So, my question: Can I use one xib and adapt states (active, inactive) and change ui for different screen? How I can do it?
Here is an example of this kind of class
In Your .m file of custom XIB class if you are using objective-c.
- (void)foo:(NSString*)labelText andButtonText:(NSString*)buttonTitle {
//Do your code here for some screen like change labels and button text
}
- (void)bar:(NSString*)labelText andButtonText:(NSString*)buttonTitle {
//Do your code here for some another screen and change labels and button text
}
In Your .h file of custom XIB class if you are using objective-c.
- (void)foo:(NSString*)labelText andButtonText:(NSString*)buttonTitle;
- (void)bar:(NSString*)labelText andButtonText:(NSString*)buttonTitle;
In your view controller where you want to display the custom UI
Create an instance of your xib or add through interfacebuilder
And On your instance of custom class call the method as required.
Below is a class I've used in one of my project to get a clear understanding.
#import <UIKit/UIKit.h>
#import "DYRateView.h"
#interface LevelAndRankDetails : UIView
#property (nonatomic, strong) IBOutlet UIView* contentView;
#property (nonatomic, strong) IBOutlet UIView* viewContainer;
#property (nonatomic, strong) IBOutlet UILabel* lblLevel;
#property (nonatomic, strong) IBOutlet UILabel* lblRanking;
#property (weak, nonatomic) IBOutlet DYRateView *viewRate;
- (void)setLevel:(NSNumber*)level andRanking:(NSNumber*)ranking;
- (void)setupUI;
#end
.m File
#import "LevelAndRankDetails.h"
#import "AppDelegate.h"
#import "Constants.h"
#implementation LevelAndRankDetails
/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect {
// Drawing code
}
*/
- (id)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]){
[self commonSetup];
}
return self;
}
-(id)initWithCoder:(NSCoder *)aDecoder
{
self = [super initWithCoder:aDecoder];
if (self)
{
[self commonSetup];
}
return self;
}
- (void)layoutSubviews {
[super layoutSubviews];
}
- (void)viewFromNibForClass {
[[NSBundle mainBundle] loadNibNamed:[[self class] description] owner:self options:nil];
[self addSubview:self.contentView];
self.contentView.frame = self.bounds;
}
- (void)commonSetup {
[self viewFromNibForClass];
//For View's Corner Radius
self.contentView.layer.cornerRadius = 12;
self.contentView.layer.masksToBounds = YES;
self.contentView.backgroundColor = kDefaultBackgroundGreyColor;
self.viewContainer.backgroundColor = kDefaultBackgroundGreyColor;//[UIColor clearColor];
self.backgroundColor = kDefaultBackgroundGreyColor;
//self.viewContainer.backgroundColor = UIColorFromRGB(0xBB9657);//[kLearnFromLightColor colorWithAlphaComponent:0.5];
self.viewRate.rate = 0;
self.viewRate.editable = NO;
self.viewRate.delegate = nil;
self.viewRate.alignment = RateViewAlignmentCenter;
self.viewRate.backgroundColor = [UIColor clearColor];
[self.viewRate setEmptyStarImage:[UIImage imageNamed:#"StarEmpty"]];
UIImage* imageFullStar = [[UIImage imageNamed:#"StarFull"] imageTintedWithColor:kSliderDarkYellowColor];
[self.viewRate setFullStarImage:imageFullStar];
self.lblLevel.textColor = [UIColor whiteColor];
self.lblRanking.textColor = [UIColor whiteColor];
//For Teacher label
}
- (void)setupUI {
self.contentView.layer.cornerRadius = 0;
self.contentView.layer.masksToBounds = YES;
self.contentView.backgroundColor = [UIColor clearColor];
self.viewContainer.backgroundColor = [UIColor clearColor];//[UIColor clearColor];
self.backgroundColor = [UIColor clearColor];
}
- (void)setRanking:(CGFloat)ranking {
self.viewRate.rate = ranking;
}
- (void)setLevel:(NSNumber*)level {
self.lblLevel.text = [NSString stringWithFormat:#"Level : %#",level];
}
- (void)setLevel:(NSNumber*)level andRanking:(NSNumber*)ranking {
if (level.integerValue > 0) {
[self setLevel:level];
}
if (ranking.doubleValue > 0) {
CGFloat rankingConverted = ranking.floatValue;
[self setRanking:rankingConverted];
}
}
#end
And this is how you use it in your view controller
LevelAndRankDetails* toolTipCustomView = [[LevelAndRankDetails alloc] initWithFrame:CGRectMake(0, 0, 250, 66)];
toolTipCustomView.backgroundColor = [UIColor blackColor];
[toolTipCustomView setLevel:#(10) andRanking:#(3)];

iOS: Dereferencing NSMutableArray

When someone votes down the question... kindly please also comment why you had voted it down.
I have a UIView (myHolderView) on which I want to place 9 or more other views.
I added some UIView (MyView) instances to an NSMutableArray of 9 elements (MyArray).
MyView has a label (UILabel) on it. Can someone please assist how to get label's text using MyArray?
Note:
I am seeing the UIViews added to main holder view and getting labels on it.
initWithFrame:(v,v,v,v) number: (value) is the init method I had overloaded init with.
//These two are declared as global variable
NSMutableArray *tiles;
MyView *tile;
#implementation ViewController
#synthesize myHolderView;
- (void)viewDidLoad
{
[super viewDidLoad];
tiles=[[NSMutableArray alloc]initWithCapacity:9];
for (int xIndex=0; xIndex<3; xIndex++)
{
for(int yIndex=0; yIndex<3; yIndex++)
{
static int label=0;
[tiles addObject:[[MyView alloc]initWithFrame:CGRectMake(value,value,value,value)
number:[[NSString alloc] initWithFormat:#"%d",label+1]]];
[self.myHolderView addSubview:tiles[label]];
//Now - when I want to print the labels onto Console as NSLog messages
//it is printing null
MyView *n=[[MyView alloc]init];
n=(MyView *)[tiles objectAtIndex:label++];
NSLog(#"%#---", n.myLabel.text);
//this also does not work. Definitely wrong dereferencing
// NSLog(#"%#---", (MyView*) [tiles ObjectAtIndex:1].mylabel.text);
//label++;
}
}
}
Please help
how to dereference NSMuableArray objects to the type what we want (the
type we know it exactly)
MyView:
- (id)initWithFrame:(CGRect)frame number:(NSString *)num;
{
self = [super initWithFrame:frame];
if (self) {
MyView *tile = [[[NSBundle mainBundle] loadNibNamed:#"XView" owner:self options:nil] objectAtIndex:0];
tile.myLabel.text=num;
[self addSubview:tile];
}
return self;
}
According to your comment, you want to add some view to your holderview. Later, you want to change text in particular view. So I suggest some way. I think, It will help you..
1) create and Add subview to your holder view
for (int xIndex=0; xIndex<9; xIndex++)
{
MyView *subView = [[MyView alloc]initWithFrame:CGRectMake(value,value,value,value)
number:[[NSString alloc] initWithFormat:#"%d",somecount+1]]]; // doesn't know why do you try this..
subView.tag = xIndex;
[self.myHolderView addSubview: subView];
}
2) Get particular subview with tag value.(No need to maintain any other array in your view controller)
After some time, you want to change text in particular view. Just try it..
MyView *subView = [self.myHolderView viewWithTag:index]; // as like, you access array
subView.myLabel.text = yourUpdateText;
#import "ViewController.h"
#interface MyView : UIView
#property UILabel *myLabel;
- (id) initWithFrame: (CGRect) rect number: (NSString *) string;
#end
#implementation MyView
- (id) initWithFrame: (CGRect) frame number: (NSString *) number {
self = [super initWithFrame:frame];
if (!self) return nil;
// Any things here
// Are you initialized label?
_myLabel = [UILabel new];
[_myLabel setText:number];
[self addSubview:_myLabel];
return self;
}
#end
#interface ViewController ()
#property UIView *myHolderView;
#end
NSMutableArray *tiles;
MyView *tile;
#implementation ViewController
#synthesize myHolderView;
- (void)viewDidLoad {
[super viewDidLoad];
tiles=[[NSMutableArray alloc]initWithCapacity:9];
int value = 1, label = 0;
myHolderView = [UIView new];
for (int xIndex=0; xIndex<3; xIndex++) {
for(int yIndex=0; yIndex<3; yIndex++) {
NSString *number = [[NSString alloc] initWithFormat:#"%d",label+1];
MyView *myView = [[MyView alloc]initWithFrame:CGRectMake(value,value,value,value)
number:number];
[tiles addObject:myView];
[self.myHolderView addSubview:tiles[label]];
//Now - when I want to print the labels onto Console as NSLog messages
//it is printing number
MyView *n=(MyView *)[tiles objectAtIndex:label++];
NSLog(#"%#---", n.myLabel.text);
}
}
// And without tiles array
for (UIView *subView in [myHolderView subviews])
for (UIView *subSubView in [subView subviews])
if ([subSubView isKindOfClass:[UILabel class]])
NSLog(#"%#", [(UILabel *) subSubView text]);
}
#end
Your problem is nothing to do with arrays or dereferencing. It's a logical issue because you are creating multiple views and nesting them.
Change the implementation of MyView:
- (id)initWithFrame:(CGRect)frame number:(NSString *)num;
{
self = [[[NSBundle mainBundle] loadNibNamed:#"XView" owner:self options:nil] objectAtIndex:0];
self.frame = frame;
self.myLabel.text = num;
return self;
}
Try something like this (typed inline so watch for issues):
- (void)viewDidLoad
{
[super viewDidLoad];
tiles = [[NSMutableArray alloc] initWithCapacity:9];
NSUInteger counter = 0;
for (int xIndex=0; xIndex<3; xIndex++)
{
for(int yIndex=0; yIndex<3; yIndex++)
{
MyView *newView = [[MyView alloc] initWithFrame:CGRectMake(value,value,value,value) number:[[NSString alloc] initWithFormat:#"%d", counter+1]]];
[self.myHolderView addSubview:newView];
[tiles addObject:newView];
MyView *logView = (MyView *)[tiles objectAtIndex:counter];
NSLog(#"view %d is %#---", counter, logView.myLabel.text);
counter++;
}
}
}

Add UIViewController as subview of UIScrollView

I am building an app with some scrolling inside. In short, this is my configuration:
1) class_1: a view with a set of elements inside (something similar to camera row) listed by using a collection view
2) class_2: a modal view called by class_1 where I show each singular element selected (from class_1). Inside the same class I have also implemented the horizontal scroll of all the elements
3) class_3: a simple viewcontroller with an imageview inside which will contain the element I will show in class_2
Running my app looks like class_3 is not added as subview of class_2 and all the singular content I try to load are not visible.
Below is my class_2 code
Interface:
#import <UIKit/UIKit.h>
#import "class_3.h"
#interface class_2 : UIViewController
#property (strong, nonatomic) IBOutlet UIPageControl *pageControl;
#property (strong, nonatomic) IBOutlet UIScrollView *scrollView;
#property (weak, nonatomic) NSArray *imageList;
#end
Implementation:
#interface class_2 () {
NSMutableArray *_viewControllers;
}
- (void)loadScrollViewWithImage:(NSUInteger)indexImage;
#end
#implementation class_2
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
// _imageList is passed from class_1 when I call class_2. Contains an array of images
self.pageControl.numberOfPages = [_imageList count];
self.pageControl.currentPage = 0;
// I store inside an array N objects as the number f images I have to show. At the beginning the array has only null objects, then it will contains the views based on the images I have scrolled.
//I am storying my images inside a view because maybe I will show more controls and not just the image. It will be much easier manage them.
_viewControllers = [[NSMutableArray alloc] init];
for (NSUInteger i = 0; i < [_imageList count]; i++) {
[_viewControllers addObject:[NSNull null]];
}
// I set some properties of my scrollview defined as outlet
self.scrollView.frame = CGRectMake(0, 0, 320, 345);
self.scrollView.contentSize = CGSizeMake(CGRectGetWidth(self.scrollView.frame) * [_imageList count], CGRectGetHeight(self.scrollView.frame));
self.scrollView.pagingEnabled = YES;
// this is set to NO, I switched to YES just now for debug (at least I can see how big the area is since there are no images visible)
self.scrollView.showsHorizontalScrollIndicator = YES;
self.scrollView.showsVerticalScrollIndicator = NO;
self.scrollView.scrollsToTop = NO;
self.scrollView.delegate = self;
// for testing now I always take the first and second elements of my array. I load both so when I move from the first image to the second is already there and there is no gap/flashing effect
[self loadScrollViewWithImage:0];
[self loadScrollViewWithImage:1];
}
#pragma mark - Private methods
- (void)loadScrollViewWithImage:(NSUInteger)indexImage {
// I scrolled until the last image, from here I can only go back
if (indexImage >= [_imageList count])
return;
// I replace the placeholder (null) object
class_3 *controller = [_viewControllers objectAtIndex:indexImage];
if ((NSNull *)controller == [NSNull null]) {
controller = [[class_3 alloc] init];
[_viewControllers replaceObjectAtIndex:indexImage withObject:controller];
}
// I add the controller's view to the scroll view - in case this is the first time I'm scrolling this image
if (controller.view.superview == nil) {
// I set my controller frame as the scrollview works as container
CGRect frame = self.scrollView.frame;
frame.origin.x = CGRectGetWidth(frame) * indexImage;
frame.origin.y = 0;
controller.view.frame = frame;
// I finally add my viewcontroller as child of my superview and subview of the scrollview
[self addChildViewController:controller];
[self.scrollView addSubview:controller.view];
[controller didMoveToParentViewController:self];
// I set an image corrisponding with the element selected from class_1
controller.imageView.image = [_imageList objectAtIndex:indexImage]
// I also tried with a fake image...just in case. No one of them is visible
//controller.imageView.image = [UIImage imageNamed:#"tempPhoto"];
}
}
My class_3 is a viewcontroller which hosts only an image view shoulb be populated with the corresponding image selezted before.
The pagecontroller is used to show where I scrolling (letf/right) and how many elements there are. The scrolling is phisically managed with the scrollview.
Here is my class_3 definition
Interface:
#import <UIKit/UIKit.h>
#import "class_3.h"
#interface class_3 : UIViewController
#property (strong, nonatomic) IBOutlet UIImageView *imageView;
#end
Implementation (nothing really impressive)
#import "class_3.h"
#interface class_3 ()
#end
#implementation class_3
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.imageView.image = [UIImage imageNamed:#"tempPhoto"];
}
#end
What am I missing?
Tnx
Your class_3 should be a UIView, instead of a UIViewController, subclass. See here

Button on iOS is not sending events on touchUpInside

I created a .xib file form my custom view.
I created .h/.m files for that view.
I ctrl dragged from button to header file to create an IBAction and set the value to touchUpInside. Here is what is happening:
http://screencast.com/t/R1WTpK7xp
WTF?
It triggers event when up is outside the button?
EDIT:
Here is the screenshot:
And what is the thing with down vote? I don't see a point in that.
View.h
#import <UIKit/UIKit.h>
#import "DrawingViewDelegate.h"
#interface DrawingBottomToolbarView : UIView
#property (weak) id <DrawingViewDelegate> delegate;
- (IBAction)lineSegmentButtonPush:(id)sender;
#end
View.m
#import "DrawingBottomToolbarView.h"
#implementation DrawingBottomToolbarView
#synthesize delegate;
- (id)initWithFrame:(CGRect)frame
{
NSLog(#"frame");
self = [super initWithFrame:frame];
if (self) {
// Initialization code
[self addSubview:[[[NSBundle mainBundle] loadNibNamed:#"DrawingBottomToolbarView" owner:self options:nil] objectAtIndex:0]];
//[[[NSBundle mainBundle] loadNibNamed:#"DrawingBottomToolbarView" owner:self options:nil] objectAtIndex:0];
//[self addSubview:self.];
}
return self;
}
//-(id)initWithCoder:(NSCoder *)aDecoder{
//
// NSLog(#"coder");
// if ((self = [super initWithCoder:aDecoder])){
// [self addSubview:[[[NSBundle mainBundle] loadNibNamed:#"DrawingBottomToolbarView" owner:self options:nil] objectAtIndex:0]];
// }
// return self;
//}
- (IBAction)lineSegmentButtonPush:(id)sender
{
NSLog(#"line push");
}
#end
I don't get it where is the problem.
EDIT 2:
I tried setting buttons as outlets and add target/action in code and same thing happens:
.h
#property (weak, nonatomic) IBOutlet UIButton *lineSegmentButton;
.m
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
[self addSubview:[[[NSBundle mainBundle] loadNibNamed:#"DrawingBottomToolbarView" owner:self options:nil] objectAtIndex:0]];
self.currentSelectedPathSegment = NoneSegment;
[self.lineSegmentButton addTarget:self action:#selector(lineSegmentButtonPush:) forControlEvents:UIControlEventTouchUpInside];
}
return self;
}
EDIT 3: Here is where I add two views. drawing view is created in code, bottomToolbar is created from .xib file.
kBottomToolbarHeight is constant with same value as height defined in .xib file.
- (void)viewWillAppear:(BOOL)animated
{
[self.view addSubview:self.drawingView];
[self.view addSubview:self.bottomToolbar];
CGRect selfRect = self.view.bounds;
CGRect drawingViewRect = selfRect;
CGRect bottomToobarRect = selfRect;
drawingViewRect.size.height = selfRect.size.height - kBottomToolbarHeight;
bottomToobarRect.size.height = kBottomToolbarHeight;
bottomToobarRect.origin.y = drawingViewRect.size.height;
self.drawingView.frame = drawingViewRect;
self.bottomToolbar.frame = bottomToobarRect;
}
The behavior you mention and show in the screencast is exactly the same as I experienced when I somewhere in the view hierarchy had a parent view with a UITapGestureRecognizer.
I'm unsure whether or not to flag your question as a possible duplicate of this one which helped me solve my problem.
For reference this is not a problem in iOS 6.0, only earlier versions.

Why is it when Custom UIView loads itself from a NIB but is also embedded in another NIB I get infinite loop

I have a problem with a custom uiview (MyCustomView) loading its view from a NIB (MyCustomView.xib).
The problem is the MyCustomView is reused in other XIBs so awakeFromNib is called.
The CustomView.xib also contains an instance of MyCustomView so loadNibNamed in MyCustomView.awakeFromNib goes into infinite loop
im getting infinite loop as:
SomeVC.xib
+ calls MyCustomView awakeFromNib
++ which calls loadNibNamed: MyCustomView.nib
+++++ but top level View is also instance of MyCustomView
....so awakeFromNib: goes into infinite loop
Im just wondering if when a custom view loads its self from a nib then top level UIView shouldnt be instance of MyCustomView?
If so how do I wire up outlet/actions (do I make MyCustomView the files owner instead?)
anyway cheers
LONG EXPLANATION:
I have a row of buttons which I want to reuse on a number of screens.
So I created a custom view
#interface ScreenMenuButtonsView : UIView
#property (retain, nonatomic) IBOutlet UIButton *buttonHome;
#property (retain, nonatomic) IBOutlet UIButton *buttonMyMusic;
#property (retain, nonatomic) IBOutlet UIButton *buttonStore;
#property (retain, nonatomic) IBOutlet UIButton *buttonSocial;
#property (retain, nonatomic) IBOutlet UIButton *buttonSettings;
#end
I wanted to layout the view in IB so I created a NIB
ScreenMenuButtonsView_iPad.xib
Files Owner: no set NSObject
VIEW: ScreenMenuButtonsView
+ UIButton
+ UIButton
+ UIButton
I want the custom view to load its own NIB internally and I used the example from
http://nathanhjones.com/2011/02/20/creating-reusable-uiviews-with-a-drop-shadow-tutorial/
http://nathanhjones.com/wp-content/uploads/2011/02/ReusableTableHeaders.zip
- (id)initWithFrame:(CGRect)frame {
//self = [super initWithFrame:frame]; // not needed - thanks ddickison
if (self) {
NSArray *nib = [[NSBundle mainBundle]
loadNibNamed:#"HeaderView"
owner:self
options:nil];
[self release]; // release object before reassignment to avoid leak - thanks ddickison
self = [nib objectAtIndex:0];
self.layer.shadowColor = [[UIColor blackColor] CGColor];
self.layer.shadowOffset = CGSizeMake(1.0, 1.0);
self.layer.shadowOpacity = 0.40;
}
return self;
}
Which is ok except this presumes you call initWithFrame somewhere to instantiate the CustomView.
The HeaderView example calls it like this:
// load the header - this could be done in viewWillAppear as well
HeaderView *header = [[HeaderView alloc]
initWithFrame:CGRectMake(0, 0, 320, 60)];
header.lblTitle.text = #"That. Just. Happened.";
tblData.tableHeaderView = header;
[header release];
I wanted to be able to use my custom view class in any other XIB
HomeScreenViewController.xib
Files Owner: HomeScreenViewController
View:
+ ....other controls
+ ScreenMenuButtonsView
The problem is when HomeScreenViewController is loaded it calls awakeFromNib on my customView:
so I moved the nib loading out initWithFrame and into a method called setupView and called it from initWithFrame AND awakeFromNib
- (id) initWithFrame:(CGRect)frame
{
if ( ( self = [super initWithFrame: frame] ) )
{
[self setUpView];
}
return self;
}
- (void)awakeFromNib
{
[self setUpView];
}
- (void) setUpView{
if (self) {
NSArray* nibViewsArray = nil;
if([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad){
//IPAD
nibViewsArray = [[NSBundle mainBundle] loadNibNamed:#"ScreenMenuButtonsView_iPad"
owner:self
options:nil];
...
}
My problem is that when HomeScreenViewController.xib is loaded:
HomeScreenViewController.xib
Files Owner: HomeScreenViewController
View:
+ ....other controls
+ ScreenMenuButtonsView
It tries to create ScreenMenuButtonsView and because its in a NIB
it calls
ScreenMenuButtonsView awakeFromNib
BUT in here I call loadNibNamed:
- (void) setUpView{
_viewSetupAlready = TRUE;
//http://nathanhjones.com/2011/02/20/creating-reusable-uiviews-with-a-drop-shadow-tutorial/
//self = [super initWithFrame:frame]; // not needed - thanks ddickison
if (self) {
NSArray* nibViewsArray = nil;
if([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad){
//IPAD
nibViewsArray = [[NSBundle mainBundle] loadNibNamed:#"ScreenMenuButtonsView_iPad"
owner:self
options:nil];
}else{
//IPHONE
nibViewsArray = [[NSBundle mainBundle] loadNibNamed:#"ScreenMenuButtonsView_iPhone"
owner:self
options:nil];
}
if(nibViewsArray){
//[self release]; // release object before reassignment to avoid leak - thanks ddickison
UIView * myView = [nibViewsArray objectAtIndex: 0];
//Check the top level object in NIB is same type as this custom class
//if wrong you probably forgot to use correct NIB name in loadNibNamed:
if([myView isMemberOfClass:[self class]]){
self = (ScreenMenuButtonsView *)myView;
}else{
NSLog(#"ERROR:top level view is not same type as custom class - are you loading the correct nib filename in loadNibNamed:\n%#", myView);
}
}else{
NSLog(#"ERROR:nibViewsArray is nil");
}
}
}
loadNibName: load
ScreenMenuButtonsView_iPad.xib
Files Owner: no set NSObject
VIEW: ScreenMenuButtonsView
+ UIButton
+ UIButton
+ UIButton
But top view is ScreenMenuButtonsView
so creates a new instance and calls awakeFromNib
and I get infinite loop.
I know why the loops occurring and instance on ScreenMenuButtonsView is loading another instance from the xib.
My question is in
ScreenMenuButtonsView_iPad.xib
Files Owner: no set NSObject
VIEW: ScreenMenuButtonsView
+ UIButton
+ UIButton
+ UIButton
should I change
VIEW: UIView
but what about outlets and actions for the button:
should I change
Files Owner: no set NSObject
to be the view class
Files Owner: ScreenMenuButtonsView
