I need a way to get all UILabels within a UIView without having to go through all the views within the UIView.
I have many other type of views, UIButtons, UIImageViews and it would be too long to go through all of them when I just need the UILabels.
I'm trying to avoid something like this:
for (UIView *view in myView.subviews)
{
if([view isKindOfClass:[UILabel class]])
{
UILabel *lbl = (UILabel*)view;
}
}
Is it possible or am I dreaming?
Create an NSArray ivar which you can add all the UILabel's to.
If you do it in code then as you create the UILabel just do
NSMutableArray *labels = [[NSMutableArray alloc] init];
// Repeat this for al labels
UILabel *label = [[UILabel alloc] in...
[labels addObject:label];
// Then
self.labels = [labels copy];
If you use IB the declare your property like this
#property (nonatomic, strong) IBOutletCollection(UILabel) NSArray *labels;
and connect all the labels up to this.
Man, you need make use recursion. (If you don't want use tags)
Try This.
-(UIView *)checkChild:(UIView *)view{
NSArray *arrayView = view.subviews;
UIView *returnView = nil;
for (UIView *auxView in arrayView) {
if ([auxView isKindOfClass:[UILabel class]]) {
return auxView;
}else{
returnView = [self checkChild:auxView];
}
}
return returnView;
}
I liked the approach of #SiddharthaMoraes, but changed it to collect all the elements found on its path. I was looking for the UILabels inside my UIViewController and couldn't find them because they where nested inside another UIView, so this recursion should solve the problem:
-(NSMutableArray *)checkChild:(UIView *)view{
NSArray *arrayView = view.subviews;
NSMutableArray *arrayToReturn = [NSMutableArray new];
for (UIView *auxView in arrayView) {
if ([auxView isKindOfClass:[MyLabel class]]) {
[arrayToReturn addObject:auxView];
}else if( auxView.subviews ){
[arrayToReturn addObjectsFromArray:[self checkChild:auxView]];
}
}
return arrayToReturn;
}
You can set the tag property for the label.. something like this...
label.tag = 100;
UILabel *lbl = [yourView viewWithTag:100];

Our iPhone app currently supports IOS 8/9/10. I am having difficulty supporting voice over accessibility for a custom UITableViewCell. I have gone through the following SO posts, but none of the suggestions have worked. I want individual components to be accessible.
Custom UITableview cell accessibility not working correctly
Custom UITableViewCell trouble with UIAccessibility elements
Accessibility in custom drawn UITableViewCell

http://useyourloaf.com/blog/voiceover-accessibility/
Unfortunately for me, the cell is not detected by the accessibility inspector. Is there a way to voice over accessibility to pick up individual elements within the table view cell? When debugging this issue on both device and a simulator, I found that the XCode calls isAccessibleElement function. When the function returns NO, then the rest of the methods are skipped. I am testing on IOS 9.3 in XCode.
My custom table view cell consists of a label and a switch as shown below.
The label is added to the content view, while the switch is added to a custom accessory view.
The interface definition is given below
#interface MyCustomTableViewCell : UITableViewCell
///Designated initializer
- (instancetype)initWithReuseIdentifier:(NSString *)reuseIdentifier;
///Property that determines if the switch displayed in the cell is ON or OFF.
#property (nonatomic, assign) BOOL switchIsOn;
///The label to be displayed for the alert
#property (nonatomic, strong) UILabel *alertLabel;
#property (nonatomic, strong) UISwitch *switch;
#pragma mark - Accessibility
// Used for setting up accessibility values. This is used to generate accessibility labels of
// individual elements.

First of all, from the pattern you described, I'm not sure why you would want to differentiate between different elements in a cell. Generally, Apple keeps every cell a single accessibility element. A great place to see the expected iOS VO behavior for cells with labels and switches is in Settings App.
If you still believe the best way to handle your cells is to make them contain individual elements, then that is actually the default behavior of a cell when the UITableViewCell itself does not have an accessibility label. So, I've modified your code below and run it on my iOS device (running 9.3) and it works as you described you would like.
You'll notice a few things.
I deleted all the custom accessibilityElements code. It is not necessary.
I deleted the override of isAccessibilityElement on the UITableViewCell subclass itself. We want default behavior.
I commented out setting the content view as an accessibilityElement -- we want that to be NO so that the tree-builder looks inside of it for elements.
I set customAccessoryView's isAccessibilityElement to NO as well for the same reason as above. Generally, NO says "keep looking down the tree" and YES says "stop here, this is my leaf as far as accessibility is concerned."
I hope this is helpful. Once again, I do really encourage you to mimic Apple's VO patterns when designing for Accessibility. I think it's awesome that you're making sure your app is accessible!

I have a class called LabelView inheriting from UIView. In the story board have a view dragged and inheriting from LabelView. Now I want to iterate through the self.superview to set the attributed text of each view. Please suggest a method to do so.
Here is my code:
int i=0;
for (UIView *view in labelView) {
if ([view isMemberOfClass:[LabelView class]]) {
[view setTag:i];
NSArray *symbols = #[#"+", #"-", #"*", #"/"];
NSString* symb = [NSString stringWithFormat:#"%#", [symbols objectAtIndex:i]];
UIFont *labelFont = [UIFont systemFontOfSize:view.bounds.size.width*0.80];
NSAttributedString *labelOperator=[[NSAttributedString alloc]initWithString:[NSString stringWithFormat:#"%#", symb]attributes:#{NSFontAttributeName: labelFont}];
CGRect textrect;
textrect.origin=CGPointMake(12, 0);
textrect.size=[labelOperator size];
[labelOperator drawInRect:textrect];
i++;
}
else{
NSLog(#"fail");
}
}
You may want to try something like this:
for (UIView *view in self.view.subviews) {
if ([view isMemberOfClass:[LabelView class]]) {
//DO WHATEVER YOU WANT
}
The above fast enumeration code iterates through all the subviews in your self.view and checks if the view is a member of your custom class which is LabelView. If it finds one, then the statements inside the if condition gets executed. Hope it helps!
The key is to go from your label view to the superview and iterate through its subviews.
for (UIView *label in labelView.superview.subviews) {
if ([label isKindOfClass:[LabelView class]]) {
// configure the label
}
}
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++;
}
}
}
I've created 5 UIView dynamically, which consists of one UILabel and one UIButton each. When I click button, the UIView will setHidden. But it works only on one not other four uiviews.

#property(nonatomic,retain)IBOutlet UILabel *welcome;
#property(nonatomic,retain)CustomView *custom;

int length=[name length];
newViews = [NSMutableArray array];
NSMutableArray *myArray = [NSMutableArray arrayWithObjects:#"cricket", #"golf",#"wrestling", #"FootBall is good game", nil];
int yAxis=44;
int lengthOfArray=[myArray count];
for(int a=0; a<=lengthOfArray; a++){
self.custom= [[CustomView alloc]initWithFrame:CGRectMake(20, yAxis, 100, 44)];

NSLog(#"yaxis is %i",yAxis);
self.custom.tag=200+a;
[newViews addObject:self.custom];
self.custom.Label = [[UILabel alloc]initWithFrame:CGRectMake(5,5, length+70, 30)];
self.custom.button=[[UIButton alloc]initWithFrame:CGRectMake(85,10,12,10)];

Kindly help me. I am new in iOS development. I need here to create UIView with differrnt reference and that reference assign to UIButton to close that particular UIView but I could not get result out.
You could use UISegmentedControl along with number of xib for each UIView.
In each UIView you can place the required UIControls and link the same.
In the delegate method of SegmentedControl 'indexDidChangeForSegmentedControl:(UISegmentedControl *)sender' on each index remove the earlier UIView and add the required UIView.
In the main header file add the IBOutlet for each UIView
#property (nonatomic, weak) IBOutlet UIView *view1;
#property (nonatomic, weak) IBOutlet UIView *view2;
In .m file in the delegate method 'indexDidChangeForSegmentedControl'
- (IBAction)indexDidChangeForSegmentedControl:(UISegmentedControl *)sender {
NSUInteger index = sender.selectedSegmentIndex;
if (UISegmentedControlNoSegment != index) {
if (currentIndex == index) {
return;
}
currentIndex = index;
switch (index) {
case 0:
{
[self.previousView removeFromSuperview];
[self.view addSubview:view1];
self.previousView = view1;
}
break;
case 1:
{
[self.previousView removeFromSuperview];
[self.view addSubview:view2];
self.previousView = view2;
}
break;
}
}
}
Hope this helps.
If you want to use properties, you will have to make a property for each view. Instead, if you want to create them dynamicaly you could store the references to each view in an array.
The next you should know/do is to add a tag to each button. A tag is just a number, which in this case should reference to its position in the Array.
Then based on the button tag (that you can retrieve from the sender) you can retrieve the proper view/button from the array and change the Hidden property on it.
For example (pseudo code/this wont compile):
Creating the views array
#property (nonatomic, strong) NSMutableArray *views;
In View did load create the views
views = [[NSMutableArray alloc] init];
int nrOfViews = 5;
for(int a=0; a<=nrOfViews; a++){
UIView *view = create UIView here.
UIButton *button = create button here.
[view addSubView: button];
[button setTag: a];
[views addObject: view];
}
reference to the view through the pointer retained in the array, find the right one based on the button tag.
-(void)buttonPressed:(UIButton *)sender
{
UIView *view = [views objectAtIndex: sender.tag]; //using the button tag to identify the right view.
[view setHidden: yes];
}
Try something like this:
- (void) buttonPressed: (UIButton*) sender
{
UIView* view = sender.superview;
view.hidden = YES;
}
You need to make some changes as follows
#property(nonatomic,strong)IBOutlet UILabel *welcome; // new arc code
#property(nonatomic,strong)UIView *custom; // new arc code
self.custom = [[UIView alloc]initWithFrame:CGRectMake(20, yAxis, 100, 44)];
I'm trying to create a scrollview with an array of clickable UIImageView's. My goal is that when an ImageView is clicked, it returns which position in the array it occupies. The problem is that i don't know how to "catch" the position's number. How do I do that?
So far I have:
- (IBAction)respondToTapGesture:(UITapGestureRecognizer *)recognizer {
NSLog(#"%#",)//here is where i want to return the element's position.
}
-(void) preenchemenu {
[menu setContentSize:CGSizeMake(400, 91)];
int x=0;
imagensmenu=[NSArray arrayWithObjects:[UIImage imageNamed:#"teste2.tiff"],[UIImage imageNamed:#"teste2.tiff"], nil];
for (int i = 0; i <3; i++) {
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(x,0 , 90, 91)];
x=x+90;
imageView.image = [imagensmenu objectAtIndex:i];
imageView.tag = 1000+ i;
imageView.userInteractionEnabled = YES;
imageView.multipleTouchEnabled = YES;
UITapGestureRecognizer *tapRecognizermenu = [[UITapGestureRecognizer alloc]initWithTarget:self action:#selector(respondToTapGesture:)];
tapRecognizermenu.numberOfTapsRequired = 1;
[imageView addGestureRecognizer:tapRecognizermenu];
[menu addSubview:imageView];
}
}
You can create an array to hold you imageViews and then find the position of your imageView in this array when it is tapped.
Add a property for this
#property (nonatomic, strong) NSMutableArray *imageViews;
initialise it in init
- (id)init...
{
self = [super init...
if (self) {
_imageViews = [NSMutableArray array];
}
return self;
}
Then amend your current method slightly to also add the imageViews to this array as well as a subview of the menu
[self.imageViews addObject:imageView];
[menu addSubview:imageView];
Then in your gesture recognizer call back you can do
- (void)respondToTapGesture:(id)sender;
{
UIView *view = [sender view];
NSLog(#"%d", [self.imageViews indexOfObject:view]);
}
Just find the index by
- (IBAction)respondToTapGesture:(UITapGestureRecognizer *)recognizer
{
UIView *view = recognizer.view;
NSLog(#"Index of image in array is %d", view.tag-1000);
}
