If I want to put emoji in my segmented control I probably want to get image on first row but get 2nd and 3rd.
How can I fix it?
Just put #{NSForegroundColorAttributeName : [UIColor whiteColor]} as text attribute for UIControlStateSelected state
#interface ViewController ()
#property (weak, nonatomic) IBOutlet UISegmentedControl *segmentedControl;
#end
#implementation ViewController
- (void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
NSDictionary *dict = #{NSForegroundColorAttributeName : [UIColor whiteColor]};
[self.segmentedControl setTitleTextAttributes:dict forState:UIControlStateSelected];
}
#end

I have a view controller that contains a scroll view. Inside of the scroll view, I have a custom header view with its own custom NIB. The issue I am having is that touch events on a button inside the custom view are not being fired. From reading other answers, I tried setting my custom view's clipsToBounds property to YES, and doing so results in no visible content for the header view. This is probably part of the problem, but I don't know how to fix it. My code below:
In the view controller:
#interface MyViewController ()
#property (weak, nonatomic) DetailHeaderView *headerView; // The custom view placed inside contentView
#property (weak, nonatomic) IBOutlet UIScrollView *scrollView;
#property (weak, nonatomic) IBOutlet UIView *contentView; // content view for scrollView
#end
#implementation MyViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Load the Header View
NSArray *views = [[NSBundle mainBundle] loadNibNamed:#"DetailHeaderView" owner:nil options:nil];
self.headerView = [views firstObject];
self.headerView.psychic = self.psychic;
// Add the header view to the scroll view
[self.contentView addSubview:self.headerView];
[self setConstraints];
}
-(void)setConstraints {
[self.view removeConstraints:self.view.constraints];
[self.scrollView removeConstraints:self.scrollView.constraints];
[self.contentView removeConstraints:self.contentView.constraints];
[self.headerView removeConstraints:self.headerView.constraints];
[self.scrollView mas_makeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(self.view);
make.right.equalTo(self.view);
make.top.equalTo(self.view);
make.bottom.equalTo(self.view);
}];
[self.contentView mas_makeConstraints:^(MASConstraintMaker *make) {
make.edges.equalTo(self.scrollView);
make.width.equalTo(self.scrollView);
}];
[self.headerView mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.contentView);
make.left.equalTo(self.contentView);
make.width.equalTo(self.contentView);
make.height.equalTo(#120);
}];
}
And in my custom view file:
#interface DetailHeaderView()
#property (weak, nonatomic) IBOutlet UIPhotoView *photoView;
#property (weak, nonatomic) IBOutlet UILabel *levelLabel;
#property (weak, nonatomic) IBOutlet UILabel *experienceLabel;
#property (weak, nonatomic) IBOutlet UIView *horizontalRuleView;
#property (weak, nonatomic) IBOutlet StarRatingView *ratingView;
#property BOOL constraintsAlreadySet;
#end
#implementation DetailHeaderView
-(void)updateConstraints {
[super updateConstraints];
// self.clipsToBounds = YES; <- When I uncomment this, I see nothing.
[self removeConstraints:self.constraints];
[self.photoView mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self).with.offset(20);
make.left.equalTo(self).with.offset(8);
make.width.equalTo(#120);
make.height.equalTo(#100);
}];
[self.levelLabel mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.photoView).with.offset(8);
make.left.equalTo(self.photoView.mas_right).with.offset(8);
}];
// self.priceButton below is the button that is not clickable.
// It is not set as a property in this .m file because it is declared as a
// public property in the .h so that the parent view can respond to events.
[self.priceButton mas_makeConstraints:^(MASConstraintMaker *make) {
make.centerY.equalTo(self.levelLabel);
make.right.equalTo(self).with.offset(-8);
}];
[self.horizontalRuleView mas_makeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(self.levelLabel);
make.top.equalTo(self.levelLabel.mas_bottom).with.offset(8);
make.right.equalTo(self.priceButton);
make.height.equalTo(#1);
}];
[self.experienceLabel mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.horizontalRuleView.mas_bottom).with.offset(8);
make.left.equalTo(self.horizontalRuleView);
}];
[self.ratingView mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.experienceLabel.mas_bottom).with.offset(8);
make.left.equalTo(self.experienceLabel);
}];
}
Again, without setting clipsToBounds in "DetailHeaderView", I see all the content, but the self.priceButton property does not have touch events sent.
Any help would be greatly appreciated!
Something in your view hierarchy is preventing touches or else swallowing them. My guess is you need to set userInteractionEnabled=YES on the contentView and/or the headerView.
I am attempting to pass information from one viewController to another using a push segue with an IBAction button named *line.

Thanks for any suggestions on why this method is not being called when the button is pushed
The only way for your IBAction to NOT get called is when the button is not appropriately connected to it. Double check that in the connections inspector.
In my app I have two views: a mapView, and a detail view. The mapView has annotations, and the annotation views have right callout buttons that push the detail view onto the stack when the callout button is pressed. In the detail view, the user can take a picture that appears on the UIImage that is on the detail view controller. What I want is for a different image to be on the detail view controller for each annotation. I have read that I can use a singleton, and I have made a singleton class, but I do not know how to use it. Can someone help me out?
Here is some code:
My MKAnnotation class:
#import <CoreLocation/CoreLocation.h>
#import <MapKit/MapKit.h>
#interface MapPoint : NSObject <MKAnnotation>
{
NSString *_address;
CLLocationCoordinate2D _coordinate;
NSNumber *_identifier;
UIImage *_image;
}
- (id)initWithAddress:(NSString*)address
coordinate:(CLLocationCoordinate2D)coordinate
title:(NSString *)t
identifier:(NSNumber *)ident;
//This is a required property from MKAnnotation
#property (nonatomic, readonly) CLLocationCoordinate2D coordinate;
//This is an optional property from MKAnnotataion
#property (nonatomic, copy) NSString *title;
#property (nonatomic, readonly, copy) NSString *subtitle;
#property (nonatomic) BOOL animatesDrop;
#property (nonatomic) BOOL canShowCallout;
#property (copy) NSString *address;
#property (copy) NSNumber *identifier;
#property (copy,nonatomic) UIImage *image;
#end
#implementation MapPoint
#synthesize title, subtitle, animatesDrop, canShowCallout;
#synthesize address = _address, coordinate = _coordinate, identifier = _identifier, image = _image;
-(id)initWithAddress:(NSString *)address
coordinate:(CLLocationCoordinate2D)coordinate
title:(NSString *)t
identifier:(NSNumber *)ident
{
self = [super init];
if (self) {
_address = [address copy];
_coordinate = coordinate;
_identifier = ident;
[self setTitle:t];
NSDate *theDate = [NSDate date];
subtitle = [NSDateFormatter localizedStringFromDate:theDate
dateStyle:NSDateFormatterMediumStyle
timeStyle:NSDateFormatterMediumStyle];
}
return self;
}
#end
Here is the detail view controller:
#import <UIKit/UIKit.h>
#class P2OViewController;
#interface PinViewController : UIViewController <UINavigationControllerDelegate, UIImagePickerControllerDelegate,UITextFieldDelegate>
{
__weak IBOutlet UILabel *label;
__weak IBOutlet UIButton *removeButton;
NSString *addressForLabel;
__weak P2OViewController *_vc;
__weak NSNumber *_identifier;
}
#property (weak, nonatomic) IBOutlet UIImageView *imageView;
#property (weak, nonatomic) IBOutlet UILabel *label;
#property (weak, nonatomic) IBOutlet UIButton *removeButton;
#property (weak, nonatomic) P2OViewController *vc;
#property (weak, nonatomic) NSNumber *identifier;
-(void)takePicture:(id)sender;
-(void)buttonPressed:(id)sender;
#end
#import "PinViewController.h"
#import "MapPoint.h"
#import "P2OViewController.h"
#implementation PinViewController
#synthesize imageView, label, removeButton;
#synthesize vc = _vc, identifier = _identifier;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
UIBarButtonItem *pic = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemCamera
target:self
action:#selector(takePicture:)];
[[self navigationItem]setRightBarButtonItem:pic];
}
return self;
}
-(void)takePicture:(id)sender
{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc]init];
//If our device has a camera, we ant to take a picture, otherwise, we just pick from photo library
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
} else {
[imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
}
[imagePicker setDelegate:self];
//Place the image picker on the screen
[self presentViewController:imagePicker
animated:YES
completion:nil];
}
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
//Get picked image from info dictionary
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
//Put the image onto the screen in out image view
[imageView setImage:image];
//Take image picker off the screen - you must call this dismiss method
[self dismissViewControllerAnimated:YES
completion:nil];
}
#end
You surely have a class implementing the MKAnnotation protocol.
In this class simply add a UIImage property and assign to every annotation its custom image.
Then when presenting the detailed view you just pass around the annotation and access its image property you defined.
EDIT
In your PinViewController simply declare a property like this
#property(nonatomic, strong) MapPoint * annotation;
Before you present your PinViewController assign the corresponding annotation to it, doing something like
detailedController.annotation = theAnnotation;
Do whatever you need to do to get the image, then store it in the annotation in this way
self.annotation.image = theImage;
Now the annotation is storing the image, so as long as you keep it in memory it will be there available for you.
The next time you push the detailed view you can perform a check to see whether that annotation has already an image or not
if(nil != self.annotation.image) {
// do something
} else {
// do something else
}
I create an modal View controller. And In I crate TableView And TextField
In vertical position all ok!
Verticlal
But in horizontal a can see all of this
How can I resize my view for it?
Here the code of call ModalView
-(IBAction)buttonTapped:(id)sender{
UYLModalViewController *modalVC = [[UYLModalViewController alloc] initWithNibName:#"UYLModalViewController" bundle:nil];
modalVC.delegate = self;
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:modalVC];
if (modalViewShowType==1)
{
nc.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentModalViewController:nc animated:YES];
}
else{
nc.modalPresentationStyle = UIModalPresentationFormSheet;
nc.view.bounds = CGRectMake(0, 0, 320, 480);
[self presentModalViewController:nc animated:YES];
//nc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
//nc.view.frame = CGRectMake(0, 0, 320, 480);//it's important to do this after presentModalViewController
//nc.view.center = self.view.center;
}
[modalVC release];
[nc release];
}
and here the declaration of controller for modalView
#protocol UYLModalViewControllerDelegate
-(void) buttonDonePassed :(NSArray *) variables;
#end
#interface UYLModalViewController : UIViewController <UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate>
{
id<UYLModalViewControllerDelegate> delegate;
//id<UITextFieldDelegate> textdelegate;
// id<UITextField> txt;
IBOutlet UITableView *tblView;
IBOutlet UITextField *textField;
NSMutableArray *cellsArray;
BOOL isAddedNewRow;
//UITextField *textField;
}
- (UITableViewCell *) getCellContentView:(NSString *)cellIdentifier :(NSInteger *)cellRow;
//-(void) clickToTextField:(id)sender;
#property (nonatomic, assign) id<UYLModalViewControllerDelegate> delegate;
#property (nonatomic, retain) IBOutlet UITableView *tblView;
#property (retain, nonatomic) IBOutlet UITextField *textField;
#end
As I can see in debug mode when the device in horizontal position it doesn't go to the tableview delegate methods =(
1) Where is defined the methode :
-(IBAction)buttonTapped:(id)sender;
I think that there is a problem with presenting modal a viewController over an
UISplitViewController...try to present it over an other ViewController to test
2) the UISplitViewController can create some problems if you use it not correctly
example: try to addSubView its view ( you can't push it )
3) Verify with the auoresizeMask of UYLModalViewController view
I tried to find an answer on the internet (this site too), but i cant find the correct answer.
Im trying to give a button an animation, so I used the QuartzCore Framework. But every time I want to play-test it, it gives me this annoying massage: no declaration of property 'newGameButton' found in the interface. I dont know what I did wrong or what I have to do now.
Here is my .h and .m file:
.h file:
#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>
#interface MainMenuViewController : UIViewController {
IBOutlet UIButton* newGameButton;
IBOutlet UIButton* statsButton;
IBOutlet UIButton* settingsButton;
CAKeyframeAnimation* popAnimation;
}
-(IBAction) newGame:(id)sender;
-(IBAction) showStats:(id)sender;
-(IBAction) showSettings:(id)sender;
#end
.m file:
#import "MainMenuViewController.h"
#import "TrafficAppDelegate.h"
#import "TrafficViewController.h"
#implementation MainMenuViewController
-(IBAction) newGame:(id)sender{
TrafficViewController* traffic = [[TrafficViewController alloc] initWithNibName:#"TrafficViewController" bundle:nil];
[self.navigationController pushViewController:traffic animated:NO];
}
-(IBAction) showStats:(id)sender{
}
-(IBAction) showSettings:(id)sender{
}
#synthesize newGameButton, statsButton, settingsButton; (This is the error causer!)
-(void)viewDidLoad{
[super viewDidLoad];
popAnimation = [CAKeyframeAnimation animationWithKeyPath:#"transform.scale"];
popAnimation.keyTimes = [NSArray arrayWithObjects:[NSNumber numberWithFloat:0.0], [NSNumber numberWithFloat:0.7], [NSNumber numberWithFloat:1.0], nil];
popAnimation.values = [NSArray arrayWithObjects: [NSNumber numberWithFloat:0.01], [NSNumber numberWithFloat:1.1], [NSNumber numberWithFloat:1.0], nil];
[popAnimation retain];
}
-(void)popView:(UIView*)view{
[view setHidden:NO];
[[view layer] addAnimation:popAnimation forKey:#"transform.scale"];
}
-(void)viewWillAppear:(BOOL)animated{
[popAnimation setDuration:0.3];
[newGameButton setHidden:YES];
[statsButton setHidden:YES];
[settingsButton setHidden:YES];
[self performSelector:#selector(popView:) withObject:newGameButton afterDelay:0.25];
[self performSelector:#selector(popView:) withObject:statsButton afterDelay:0.3];
[self performSelector:#selector(popView:) withObject:settingsButton afterDelay:0.35];
}
#end
I am totally clueless, so please help!
The error is self-descriptive - you need to declare properties you synthesize in class interface, e.g.:
#interface MainMenuViewController : UIViewController {
...
}
...
#property (nonatomic, retain) IBOutlet UIButton* settingsButton;
#end
I'd suggest (Re-)reading about properties in Objective-c reference docs
You're trying to access a property that simply does not exist.
Look at your #interface, do you see any #property declarations?
This will work:
#interface MainMenuViewController : UIViewController {
IBOutlet UIButton* newGameButton;
IBOutlet UIButton* statsButton;
IBOutlet UIButton* settingsButton;
CAKeyframeAnimation* popAnimation;
}
#property (nonatomic, retain) IBOutlet UIButton *newGameButton, *statsButton, *settingsButton;
