How can i make clickable uiimage? - ios

I have one menubar as a uiimage. I want to make 5 menu on this menubar are clickable and link to another view. Can anyone tell me the way i can do that? I found people using uibutton on the uiimage, Is that fine for me and how can i separate the menu bar to 5 pieces.
Thanks for both rmaddy and Brent Royal-Gordon
I decided to use the uiimage as a menubar background and add the uibutton on it. i try some thing like this:
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"MOVIE" ofType:#"MP4"]];
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayer];
moviePlayer.controlStyle = MPMovieControlStyleNone;
moviePlayer.repeatMode = MPMovieRepeatModeOne;
moviePlayer.shouldAutoplay = YES;
moviePlayer.scalingMode = MPMovieScalingModeFill;
[moviePlayer.view setFrame:CGRectMake(0,0,1330,320)];
[scrollView setBackgroundColor:[UIColor blackColor]];
[scrollView setContentSize:CGSizeMake(1330,320)];
[scrollView setScrollEnabled: YES];
[scrollView setShowsHorizontalScrollIndicator:NO];
[scrollView setShowsVerticalScrollIndicator:NO];
[scrollView addSubview:moviePlayer.view];
[self.view addSubview:scrollView];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:image.frame];
UIImage *menubar = [UIImage imageNamed:#"BG.jpg"];
imageView = [[UIImageView alloc] initWithImage:menubar];
imageView.contentMode = UIViewContentModeScaleToFill;
imageView.frame = CGRectMake(0, 258, imageView.frame.size.width, 25);
[self.view addSubview:imageView];
[imageView setUserInteractionEnabled:YES];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0,258,30,25)];
[btn addTarget:self action:#selector(buttonPress:) forControlEvents:UIControlEventTouchUpInside];
[btn setTitle:#"HOME" forState:UIControlStateNormal];
[imageView addSubview:btn];
but the button is not visible on screen when i run on the simulator. What did i do wrong?

Using a gesture recognizer is a bad idea because:
It forces you to interpret the touch areas for each submenu yourself.
It's opaque to VoiceOver.
It doesn't show a highlight when the user touches a button. These sorts of highlights help the user understand what the user interface is doing, so they're very valuable.
What you should do is split the single image into five in a graphics tool like Photoshop, and make each of these slices the image of a UIButton. You'll need to design highlighted states for these images (shown when one of them is held down), but you should be doing that anyway.
If you must slice the image in code, you can do that by using UIGraphicsBeginImageContextWithOptions(size, NO, 0.0) and drawing your big image using drawAtPoint: with an appropriate offset to get the slice you want, but 99.99999% of the time, it'll make more sense to slice the images once on your big, beefy, wall-plug-powered Mac than every time your app runs on a tiny, slow, battery-powered iOS device.

Use a UITapGestureRecognizer with the UIImageView containing your image. You will need to set the userInteractionEnabled property to YES on the image view.
When you get the tap event, look at where in the view the tap occurred. Based on the location, perform one of the five menu actions.
If you want more control, you may be better off splitting the image into 5 and creating 5 UIButton instances instead.

Why you add it the buttons to image view ? Just adding it to the View. It will solve the problem(as i understand).
[imageView addSubview:btn];
Try like this
[self.view addSubview:btn];
Hope this helps

issue is with the Width of the button.Try
this
[btn setFrame:CGRectMake(0,258,100,50)]
(increase width to 100)
and you may need to change the title colour if your background is white
[btn setTitleColor:[UIColor blackColor] forState:
UIControlStateNormal];

you Can first add button view then add imageview on the button please see bellow code :
//Add first button
UIButton *btnImage = [UIButton buttonWithType:UIButtonTypeCustom];
btnImage.frame = CGRectMake(0, 4, 60, 56);
btnImage.backgroundColor = [UIColor colorWithRed:231.0f/255.0f green:232.0f/255.0f blue:234.0f/255.0f alpha:1.0];
btnImage.layer.borderColor = [UIColor colorWithRed:183.0f/255.0f green:184.0f/255.0f blue:186.0f/255.0f alpha:1.0].CGColor;
btnImage.layer.borderWidth = 1.0f;
// Add imageview on button
UIImageView *yourImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
[yourImageView setImage:[UIImage imageNamed:#"myimage.png"]];
yourImageView.center = CGPointMake(btnImage.frame.size.width/2, btnImage.frame.size.height/2);
[btnImage addSubview:yourImageView];
[self.view addSubview:btnImage];

UIBarButtonItem Target Method is not working

Actually i want to place image and label on the toolbar as a UIBarButtonItem and provide a clickable effect to that Button.
So what i have done here is I have created one custom view and placed Image and Label on the same custom view and finally placed this custom view as UIBarButtonItem CustomView.
But when i set target and action for the same UIBarButtonItem, it is not calling the selector method.
The entire code is below.
Can anybody suggest me what's the mistake in my code ? and is there any other approach to achieve the same ????
Early suggestions would be much appreciated.
- (void)viewDidLoad
{
[super viewDidLoad];
[self.navigationController setToolbarHidden:NO];
UIView *customView = [[UIView alloc]
initWithFrame:CGRectMake(0,0,self.navigationController.toolbar.frame.size.width,self.navigationController.toolbar.frame.size.height)];
customView.backgroundColor = [UIColor colorWithRed:62.0/255.0 green:187.0/255.0 blue:150.0/255.0 alpha:1.0];
[self.navigationController.toolbar addSubview:customView];
UIImageView *imgView = [[UIImageView alloc]initWithFrame:CGRectMake(60,0,44,44)];
imgView.image = [UIImage imageNamed:#"documentImage.png"];
[customView addSubview:imgView];
UILabel *lbl = [[UILabel alloc]initWithFrame:CGRectMake(104,0,145,44)];
lbl.text = #"Scan Document";
lbl.textAlignment = NSTextAlignmentLeft;
[customView addSubview:lbl];
UIBarButtonItem *bar = [[UIBarButtonItem alloc]initWithCustomView:customView];
bar.target = self;
bar.action = #selector(scanDocument);
self.toolbarItems = [NSArray arrayWithObjects:bar, nil];
}
If you want to create button right hand side here is the code. i have already implemented it and working fine.
//Button Right side
UIImage *imgFavRest = [UIImage imageNamed:#"documentImage.png"];
UIButton *cart = [UIButton buttonWithType:UIButtonTypeCustom];
[cart setImage:imgFavRest forState:UIControlStateNormal];
cart.frame = CGRectMake(0, 0, imgFavRest.size.width, imgFavRest.size.height);
[cart addTarget:self action:#selector(showCart) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *rightBtn = [[UIBarButtonItem alloc] initWithCustomView:cart];
self.navigationItem.rightBarButtonItem = rightBtn;
Then use method like this . that's all
-(void)cartItemCount{
// Method
}
float textwidth = 50; // according to your text
UIImage *image = [UIImage imageNamed:#"logout"];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.bounds = CGRectMake( 10, 0, image.size.width+textwidth, image.size.height );
[btn addTarget:self action:#selector(scanDocument) forControlEvents:UIControlEventTouchUpInside];
[btn setImage:image forState:UIControlStateNormal];
[btn setTitle:#"test" forState:UIControlStateNormal];
[btn setTitleEdgeInsets:UIEdgeInsetsMake(0.0, 5.0, 0.0, 0.0)];
//Adjust the coordinates and size of your button as your requirement.This is a sample code to guide you.
//PS:Take a UIButton in the nib file>Make it a custom button>Connect the IBOutlet to your custom button in the nib file.Thats it.
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithCustomView:btn];
self.navigationItem.rightBarButtonItem = rightButton;
I see very complicated answers, all of them using code. However, if you are using Interface Builder, there is a very easy way to do this:
Select the button and set a title and an image. Note that if you set
the background instead of the image then the image will be resized if
it is smaller than the button.IB basic image and title
Set the position of both items by changing the edge and insets. You
could even control the alignment of both in the Control section.
IB position set IB Control set
You could even use the same approach by code, without creating UILabels and UIImages inside as other solutions proposed. Always Keep It Simple!
EDIT: Attached a small example having the 3 things set (title, image and background) with correct insets Button preview
Note:: UIBarButtonItem inherits from UIBarItem and NSObject so it doesn't know anything about touches. It would be nice if the docs mentioned that the action and target properties only apply if the custom view is a UIButton.

in landscape no showing image and button

I have added one imageview, 2 button in one view controller in code. In portrait mode its working well. But in landscape mode not able to see the image and button.
#implementation ViewController {
UIImageView* imgView; // your UIImageView
}
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[[self navigationController] setNavigationBarHidden:YES animated:YES];
UIImage* img1 = [UIImage imageNamed:#"11.jpg"];
UIImage* img2 = [UIImage imageNamed:#"s2.jpg"];
imgView = [[UIImageView alloc] initWithFrame:self.view.frame]; // create a UIImageView with the same size as the view.
imgView.animationImages = #[img1, img2]; // use a nice NSArray literal to pass in your images.
imgView.animationDuration = 2.0*2.0; // 2 seconds for each image (x3 images)
[self.view addSubview:imgView]; // add UIImageView to view
[imgView startAnimating]; // start animating
// button one
UIButton* button = [[UIButton alloc] initWithFrame:CGRectMake(0.0, self.view.frame.size.height-50, self.view.frame.size.width/2 , 50.0)];
[button setBackgroundColor:[UIColor colorWithRed:188/255.0f green:155/255.0f blue:211/255.0f alpha:0.6f]];
[button setTitle:#"Sign Up" forState:UIControlStateNormal];
[button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal]; // title color
[button addTarget:self action:#selector(method:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
// Button Two
UIButton* button1 = [[UIButton alloc] initWithFrame:CGRectMake(self.view.frame.size.width/2, self.view.frame.size.height-50, self.view.frame.size.width/2 , 50.0)];
[button1 setBackgroundColor:[UIColor colorWithRed:188/255.0f green:155/255.0f blue:211/255.0f alpha:0.6f]];
[button1 setTitle:#"Sign In" forState:UIControlStateNormal];
[button1 addTarget:self action:#selector(method:) forControlEvents:UIControlEventTouchUpInside];
[button1 setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal]; // title color
[self.view addSubview:button1];
// Border color for one button
UIView *leftBorder = [[UIView alloc] initWithFrame:CGRectMake(0, 1, 1, button.frame.size.height)];
leftBorder.backgroundColor = [UIColor colorWithRed:237/255.0f green:211/255.0f blue:246/255.0f alpha:0.6f];
[button1 addSubview:leftBorder];
}
Why its not working well for landscape. Please help me, for portrait its working well. For landscape its not working ..
It's not working in landscape because when we rotate to landscape the button and image view, as you have positioned them in your code, are located below the bottom of the screen.
You will have to implement Auto Layout. It will fix the problem. Please avoid hard coding the positions as will create problems in UI. If you want to hard code the points then make your app in either portrait mode or landscape mode.
In auto layout constraints can be set programmatically as well. Just check which is feasible for you and implement it.

How to place a button on animation image in iOS?

In my app, I have an array of image, which is getting animated for every second.
I used the following code,
animateArrayImages = [NSArray arrayWithObjects:
[UIImage imageNamed:#"gallery-img-1.png"],
[UIImage imageNamed:#"gallery-img-2.png"],nil];
animateImageView.animationImages = animateArrayImages;
animateImageView.animationDuration = 1.0f;
animateImageView.animationRepeatCount = 0;
[animateImageView startAnimating];
UIButton *button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(20, 20, 20, 20)];
[self.view addSubview:button];
But I am getting an output like this
The button is getting displayed in the background of the image.
But I want to display it befor the image
If you want to bring the button on top of the image, you can call the following method after addSubview:
[self.view bringSubviewToFront:button];

Scrolling an Image with ImageView iOS

I'm trying to make an app for a restaurant and the to display the food menu as a scrollable image. The image is pulled form a config file.
- (void)viewDidLoad
{
[super viewDidLoad];
// back button
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:#"btn-back.png"] forState:UIControlStateNormal];
button.frame = CGRectMake(0.0f, 0.0f, 46.0f, 28.0f);
[button addTarget:self action:#selector(back) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.leftBarButtonItem = customBarItem;
[customBarItem release];
[self setTitle:[menu objectForKey:#"title"]];
[scrollView2 setScrollEnabled:YES];
NSString *imageName = [menu objectForKey:#"imageName"];
if (![imageName isEqualToString:#""]) {
UIImage *image = [UIImage imageNamed:imageName];
[imageView setImage:image];
[scrollView2 addSubview:imageView];
[imageView release];
}
[textView setText:[menu objectForKey:#"description"]];
}
As of now the image doesn't scroll, but appears as a static image. Could anyone please help me modify this code so the user can vertically scroll the image.
Thanks a lot.
You should use a UIScrollViewand add the UIImageView as subview of the contentView.
And then set the contentsize of the scrollview as the imageviews size.
[imageView setImage:image];
[scrollView2.contentView addSubview:imageView];
[scrollView2 setContentSize:image.frame.size];
[imageView release];
have no Mac to test at the moment but that should work.
I agree mostly with what Seega wrote. Your imageView must be subview of a scrollView. Then, don't forget to set the scrollView's contentSize & the minimum&maximumZoomScale & and the imageView's frame:
self.scrollView.contentSize = self.imageView.image.size;
self.imageView.frame = CGRectMake(0, 0, self.imageView.image.size.width, self.imageView.image.size.height);
self.scrollView.minimumZoomScale = // some number between 0 and 1, default is 1, so no zoom
self.scrollView.maximumZoomScale = // some number larger than 1, default is 1, so no zoom
self.scrollView.zoomScale = 1 // starting zoom scale
A nice place to put this code is in
-(void)viewWillLayoutSubviews{}
Thus it will be executed everytime the view appears & also whenever the device is rotated.

UIButton Image + Text IOS

I need a UIButton with image & text. Image should be in the top & text comes under the image both should be clickable.
I see very complicated answers, all of them using code. However, if you are using Interface Builder, there is a very easy way to do this:
Select the button and set a title and an image. Note that if you set the background instead of the image then the image will be resized if it is smaller than the button.

EDIT: Attached a small example having the 3 things set (title, image and background) with correct insets
I think you are looking for this solution for your problem:
UIButton *_button = [UIButton buttonWithType:UIButtonTypeCustom];
[_button setFrame:CGRectMake(0.f, 0.f, 128.f, 128.f)]; // SET the values for your wishes
[_button setCenter:CGPointMake(128.f, 128.f)]; // SET the values for your wishes
[_button setClipsToBounds:false];
[_button setBackgroundImage:[UIImage imageNamed:#"jquery-mobile-icon.png"] forState:UIControlStateNormal]; // SET the image name for your wishes
[_button setTitle:#"Button" forState:UIControlStateNormal];
[_button.titleLabel setFont:[UIFont systemFontOfSize:24.f]];
[_button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; // SET the colour for your wishes
[_button setTitleColor:[UIColor redColor] forState:UIControlStateHighlighted]; // SET the colour for your wishes
[_button setTitleEdgeInsets:UIEdgeInsetsMake(0.f, 0.f, -110.f, 0.f)]; // SET the values for your wishes
[_button addTarget:self action:#selector(buttonTouchedUpInside:) forControlEvents:UIControlEventTouchUpInside]; // you can ADD the action to the button as well like
...the rest of the customisation of the button is your duty now, and don't forget to add the button to your view.
UPDATE #1 and UPDATE #2
or, if you don't need a dynamic button you could add your button to your view in the Interface Builder and you could set the same values at there as well. it is pretty same, but here is this version as well in one simple picture.
you can also see the final result in the Interface Builder as it is on the screenshot.
Xcode-9 and Xcode-10 Apple done few changes regarding Edge Inset now, you can change it under size-inspector.
Please follow below steps:
Step-1:
Input text and select image which you want to show:
Step-2:
Select button control as per your requirement as shown in below image:
Step-3:
Now go-to size inspector and add value as per your requirement:
swift version:
var button = UIButton()
newGameButton.setTitle("Новая игра", for: .normal)
newGameButton.setImage(UIImage(named: "energi"), for: .normal)
newGameButton.backgroundColor = .blue
newGameButton.imageEdgeInsets.left = -50
In my case, I wanted to add UIImage to the right and UILabel to the left. Maybe I can achieve that by writing code (like the above mentioned), but I prefer not to write code and get it done by using the storyboard as much as possible. So this is how did it:
First, write down something in your label box and select an image that you want to show:
And that will create a button looking like this:
Next, look for Semantic and select Force Right-to-Left (If you don't specify anything, then it will show the image to the left and label to the right like the above image):
Finally, you'll see UIImage to the right and UILabel to the left:
To add space between a label and an image, go to the Size inspector and change those values depending on your requirement:
That's it!
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.imageView.image = [UIImage imageNamed:#"your image name here"];
button.titleLabel.text = #"your text here";
but following code will show label above and image in background
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.background.image = [UIImage imageNamed:#"your image name here"];
button.titleLabel.text = #"your text here";
There is no need to use label and button in same control because UIButton has UILabel and UIimageview properties.
Use this code:
UIButton *sampleButton = [UIButton buttonWithType:UIButtonTypeCustom];
[sampleButton setFrame:CGRectMake(0, 10, 200, 52)];
[sampleButton setTitle:#"Button Title" forState:UIControlStateNormal];
[sampleButton setFont:[UIFont boldSystemFontOfSize:20]];
[sampleButton setBackgroundImage:[[UIImage imageNamed:#"redButton.png"]
stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal];
[sampleButton addTarget:self action:#selector(buttonPressed)
forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:sampleButton]
You should create custom imageview for image and custom label for text and you add to your button as subviews. That's it.
UIButton *yourButton = [UIButton buttonWithType:UIButtonTypeCustom];
yourButton.backgroundColor = [UIColor greenColor];
yourButton.frame = CGRectMake(140, 40, 175, 30);
[yourButton addTarget:self action:#selector(yourButtonSelected:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:yourButton];
UIImageView *imageView1 = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, yourButton.frame.size.width, yourButton.frame.size.height/2)];
imageView1.image =[UIImage imageNamed:#"images.jpg"];
[yourButton addSubview:imageView1];
UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(0, yourButton.frame.size.height/2, yourButton.frame.size.width, yourButton.frame.size.height/2)];
label.backgroundColor = [UIColor greenColor];
label.textAlignment= UITextAlignmentCenter;
label.text = #"ButtonTitle";
[yourButton addSubview:label];
For testing purpose, use yourButtonSelected: method
-(void)yourButtonSelected:(id)sender{
NSLog(#"Your Button Selected");
}
I think it will be helpful to you.
Use this code:
UIButton *button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
button.imageView.frame=CGRectMake(0.0f, 0.0f, 50.0f, 44.0f);///You can replace it with your own dimensions.
UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(0.0f, 35.0f, 50.0f, 44.0f)];///You can replace it with your own dimensions.
[button addSubview:label];
I encountered the same problem, and I fix it by creating a new subclass of UIButton and overriding the layoutSubviews: method as below :
-(void)layoutSubviews {
[super layoutSubviews];
// Center image
CGPoint center = self.imageView.center;
center.x = self.frame.size.width/2;
center.y = self.imageView.frame.size.height/2;
self.imageView.center = center;
//Center text
CGRect newFrame = [self titleLabel].frame;
newFrame.origin.x = 0;
newFrame.origin.y = self.imageView.frame.size.height + 5;
newFrame.size.width = self.frame.size.width;
self.titleLabel.frame = newFrame;
self.titleLabel.textAlignment = UITextAlignmentCenter;
}
I think that the Angel García Olloqui's answer is another good solution, if you place all of them manually with interface builder but I'll keep my solution since I don't have to modify the content insets for each of my button.
Make UIImageView and UILabel, and set image and text to both of this....then Place a custom button over imageView and Label....
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"search.png"]];
imageView.frame = CGRectMake(x, y, imageView.frame.size.width, imageView.frame.size.height);
[self.view addSubview:imageView];
UILabel *yourLabel = [[UILabel alloc] initWithFrame:CGRectMake(x, y,a,b)];
yourLabel.text = #"raj";
[self.view addSubview:yourLabel];
UIButton * yourBtn=[UIButton buttonWithType:UIButtonTypeCustom];
[yourBtn setFrame:CGRectMake(x, y,c,d)];
[yourBtn addTarget:self action:#selector(#"Your Action") forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:yourBtn];
It's really simple,just add image to background of you button and give text to titlelabel of button for uicontrolstatenormal.
That's it.
[btn setBackgroundImage:[UIImage imageNamed:#"img.png"] forState:UIControlStateNormal];
[btn setContentVerticalAlignment:UIControlContentVerticalAlignmentBottom];
[btn setTitle:#"Click Me" forState:UIControlStateNormal];
