How can I make this text using single UILabel or give any other solution to achieve this design.
You can use NSTextAttachment for that behaviour. I modify this for position of attachment.
All code :
#IBOutlet weak var lbl: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
let string = "Urban points users average montly saving is "
let normalNameString = NSMutableAttributedString.init(string: string)
let attachment = NSTextAttachment()
attachment.image = imageHelper.pgImage(textValue: "QAR 115 ", lbl: lbl)
attachment.bounds = CGRect(x: 0, y: (lbl.font.capHeight - attachment.image!.size.height).rounded() / 2, width: attachment.image!.size.width, height: attachment.image!.size.height)
normalNameString.append(NSAttributedString(attachment: attachment))
normalNameString.append(NSAttributedString(string: "You have saved "))
let attachment2 = NSTextAttachment()
attachment2.image = imageHelper.pgImage(textValue: "QAR 29",textColor: UIColor.yellow,backgroundColor: UIColor.black , lbl: lbl)
attachment2.bounds = CGRect(x: 0, y: (lbl.font.capHeight - attachment2.image!.size.height).rounded() / 2, width: attachment2.image!.size.width, height: attachment2.image!.size.height)
normalNameString.append(NSAttributedString(attachment: attachment2))
normalNameString.append(NSAttributedString(string: " this month"))
lbl.attributedText = normalNameString
}
}
class imageHelper{
static func pgImage(textValue:String,textColor : UIColor = UIColor.white , backgroundColor : UIColor = UIColor.red,lbl : UILabel) ->UIImage{
let label = UILabel(frame: CGRect(x: 0, y: 0, width: (textValue as NSString).size(withAttributes: [NSAttributedString.Key.font : lbl.font!]).width, height: lbl.frame.size.height))
label.font = lbl.font
label.textAlignment = .center
label.textColor = textColor
label.backgroundColor = backgroundColor
label.layer.borderColor = UIColor.darkGray.cgColor
label.layer.borderWidth = 1
label.layer.cornerRadius = label.frame.size.height/2
label.layer.masksToBounds = true
label.text = textValue
label.numberOfLines = 1
UIGraphicsBeginImageContextWithOptions(label.bounds.size, false,UIScreen.main.scale)
label.layer.render(in: UIGraphicsGetCurrentContext()!)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return image!
}
}
And the result is :
I need to set the rockwell-bold font in the navigation title, but it is cropped for me. how can I fix this problem or change the height of the navigation titleenter image description here
let customText = NSLocalizedString("your_title", comment: "")
let title:NSMutableAttributedString = NSMutableAttributedString(string: customText, attributes: [.font: UIFont(name: "font_name", size: 20.0) ])
let size = title.size()
let width = size.width
guard let height = navigationController?.navigationBar.frame.size.height else {return}
let titleLabel = UILabel(frame: CGRect(x: 0,y: 0, width: width, height: height))
titleLabel.attributedText = title
titleLabel.numberOfLines = 0
titleLabel.textAlignment = .center
navigationItem.titleView = titleLabel
I have the following code which shows an icon on the left side of a uilabel, my question is how can I put the icon on the right side of the uilabel:
let attachment = NSTextAttachment()
attachment.image = UIImage(named: "ic_person")
attachment.bounds = CGRect(x: 0, y: -3, width: 15, height: 15)
let attachmentStr = NSAttributedString(attachment: attachment)
let myString = NSMutableAttributedString(string: "")
myString.append(attachmentStr)
let myString1 = NSMutableAttributedString(string: item_empresa[indexPath.item].nombre_emp!)
myString.append(myString1)
cell.lbl_nombreEmpresa.attributedText = myString
Thanks in advance
You can put the image after the text by appending attachment after appending the text itself
let attachment = NSTextAttachment()
attachment.image = UIImage(named: "ic_person")
attachment.bounds = CGRect(x: 0, y: -3, width: 15, height: 15)
let attributedString = NSMutableAttributedString(string: item_empresa[indexPath.item].nombre_emp ?? "")
attributedString.append(NSAttributedString(attachment: attachment))
cell.lbl_nombreEmpresa.attributedText = attributedString
The Android API has a very convenient class for this, IconGenerator. Using the IconGenerator in my Android app, I can easily make a marker that:
is a simple rectangle with the color of my choosing.
resizes to hold text of any length.
is NOT an info window - I'd like the marker itself to contain the text as shown in the image below from the android version.
// Android - problem solved with IconGenerator
IconGenerator iconGenerator = new IconGenerator(context);
iconGenerator.setStyle(IconGenerator.STYLE_GREEN); // or any other color
Bitmap iconBitmap = iconGenerator.makeIcon(myString);
Marker m = new MarkerOptions().icon(BitmapDescriptorFactory.fromBitmap(iconBitmap))
.position(myLatLng);
map.addMarker(m); // map is a com.google.android.gms.maps.GoogleMap
Is there a way to do something as simple as this in iOS using Swift?
There has been a recent release of the iOS api that allows "marker customization", but I don't see how to apply it to this use case.
// iOS (Swift) - I don't know how to create the icon as in code above
let marker = GMSMarker(position: myLatLng)
marker.icon = // How can I set to a rectangle with color/text of my choosing?
marker.map = map // map is a GMSMapView
Here is what I have done
let marker = GMSMarker()
// I have taken a pin image which is a custom image
let markerImage = UIImage(named: "mapMarker")!.withRenderingMode(.alwaysTemplate)
//creating a marker view
let markerView = UIImageView(image: markerImage)
//changing the tint color of the image
markerView.tintColor = UIColor.red
marker.position = CLLocationCoordinate2D(latitude: 28.7041, longitude: 77.1025)
marker.iconView = markerView
marker.title = "New Delhi"
marker.snippet = "India"
marker.map = mapView
//comment this line if you don't wish to put a callout bubble
mapView.selectedMarker = marker
The output is
And my marker image was
You can change your color as per your need. Also if you want something in rectange, you can just create a simple small rectangular image and use it like I did above and change the color of your need.
Or if you want a rectangle with text within it, you can just create a small UIView with some label and then convert that UIView in UIImage and can do the same thing.
//function to convert the given UIView into a UIImage
func imageWithView(view:UIView) -> UIImage {
UIGraphicsBeginImageContextWithOptions(view.bounds.size, false, 0.0)
view.layer.render(in: UIGraphicsGetCurrentContext()!)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return image!
}
Hope it helps!!
Here is what i have done for solving the same issue, that you are facing.
I have added below image in my image assets,
Now i added below method in my code:
-(UIImage*)drawText:(NSString*)text inImage:(UIImage*)image
{
UIFont *font = [UIFont boldSystemFontOfSize:11];
CGSize size = image.size;
UIGraphicsBeginImageContextWithOptions(size, NO, 0.0f);
[image drawInRect:CGRectMake(0, 0, size.width, size.height)];
CGRect rect = CGRectMake(0, 0, image.size.width, image.size.height);
NSMutableParagraphStyle *paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
paragraphStyle.alignment = NSTextAlignmentCenter;
NSDictionary *attributes = #{
NSFontAttributeName : font,
NSParagraphStyleAttributeName : paragraphStyle,
NSForegroundColorAttributeName : [UIColor redColor]
};
CGSize textSize = [text sizeWithAttributes:attributes];
CGRect textRect = CGRectMake((rect.size.width-textSize.width)/2, (rect.size.height-textSize.height)/2 - 2, textSize.width, textSize.height);
[text drawInRect:CGRectIntegral(textRect) withAttributes:attributes];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
Now, I called this method, while assigning icon to GMSMarker, like this:
marker.icon = [self drawText:#"$33.6" inImage:[UIImage imageNamed:#"icon-marker"]];
It will generate the image icon like below:
Here, I kept the background Image size fixed, as i needed. You can still customize it to adjust it according to text size, as well as multiple lines.
UPDATE
Updated code in Swift:
func drawText(text:NSString, inImage:UIImage) -> UIImage? {
let font = UIFont.systemFont(ofSize: 11)
let size = inImage.size
//UIGraphicsBeginImageContext(size)
let scale = UIScreen.main.scale
UIGraphicsBeginImageContextWithOptions(inImage.size, false, scale)
inImage.draw(in: CGRect(x: 0, y: 0, width: size.width, height: size.height))
let style : NSMutableParagraphStyle = NSMutableParagraphStyle.default.mutableCopy() as! NSMutableParagraphStyle
style.alignment = .center
let attributes:NSDictionary = [ NSAttributedString.Key.font : font, NSAttributedString.Key.paragraphStyle : style, NSAttributedString.Key.foregroundColor : UIColor.black ]
let textSize = text.size(withAttributes: attributes as? [NSAttributedString.Key : Any])
let rect = CGRect(x: 0, y: 0, width: inImage.size.width, height: inImage.size.height)
let textRect = CGRect(x: (rect.size.width - textSize.width)/2, y: (rect.size.height - textSize.height)/2 - 2, width: textSize.width, height: textSize.height)
text.draw(in: textRect.integral, withAttributes: attributes as? [NSAttributedString.Key : Any])
let resultImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return resultImage
}
You can simply add a custom view as marker in Google Map.
let marker = GMSMarker(position: coordinate)
marker.iconView = view // Your Custom view here
You can use imageView (for containing that orange color box) and label (for text) above it
I tried to rewrite Mehul Thakkar answer to Swift 3. Hope it will work for you. But it really easier to make custom view as Dari said.
func drawText(text:NSString, inImage:UIImage) -> UIImage? {
let font = UIFont.systemFont(ofSize: 11)
let size = inImage.size
UIGraphicsBeginImageContext(size)
inImage.draw(in: CGRect(x: 0, y: 0, width: size.width, height: size.height))
let style : NSMutableParagraphStyle = NSMutableParagraphStyle.default.mutableCopy() as! NSMutableParagraphStyle
style.alignment = .center
let attributes:NSDictionary = [ NSFontAttributeName : font, NSParagraphStyleAttributeName : style, NSForegroundColorAttributeName : UIColor.red ]
let textSize = text.size(attributes: attributes as? [String : Any])
let rect = CGRect(x: 0, y: 0, width: inImage.size.width, height: inImage.size.height)
let textRect = CGRect(x: (rect.size.width - textSize.width)/2, y: (rect.size.height - textSize.height)/2 - 2, width: textSize.width, height: textSize.height)
text.draw(in: textRect.integral, withAttributes: attributes as? [String : Any])
let resultImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return resultImage
}
Here a Swift 5 version of Eridana's Swift conversion of Mehul Thakkar's answer.
func drawTextT(text:NSString, inImage:UIImage) -> UIImage? {
let font = UIFont.systemFont(ofSize: 11)
let size = inImage.size
UIGraphicsBeginImageContext(size)
inImage.draw(in: CGRect(x: 0, y: 0, width: size.width, height: size.height))
let style : NSMutableParagraphStyle = NSMutableParagraphStyle.default.mutableCopy() as! NSMutableParagraphStyle
style.alignment = .center
let attributes:NSDictionary = [ NSAttributedString.Key.font : font, NSAttributedString.Key.paragraphStyle : style, NSAttributedString.Key.foregroundColor : UIColor.red ]
//let textSize = text.size(attributes: attributes as? [String : Any])
let textSize = text.size(withAttributes: attributes as? [NSAttributedString.Key : Any] )
let rect = CGRect(x: 0, y: 0, width: inImage.size.width, height: inImage.size.height)
let textRect = CGRect(x: (rect.size.width - textSize.width)/2, y: (rect.size.height - textSize.height)/2 - 2, width: textSize.width, height: textSize.height)
text.draw(in: textRect.integral, withAttributes: attributes as? [NSAttributedString.Key : Any] )
let resultImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return resultImage
}
Simplest way to achieve if you have just 1 image :
marker.icon = #imageLiteral(resourceName: "fault_marker")
1) In latest XCode write marker.icon = "imageLiteral".
2) Double click the dummy image icon appeared just now.
3) select desired image.
//func to get Image view
// Url String :- Your image coming from server
//image :- Background image
func drawImageWithProfilePic(urlString:String, image: UIImage) -> UIImageView {
let imgView = UIImageView(image: image)
imgView.frame = CGRect(x: 0, y: 0, width: 90, height: 90)
let picImgView = UIImageView()
picImgView.sd_setImage(with:URL(string: urlString))
picImgView.frame = CGRect(x: 0, y: 0, width: 40, height: 40)
imgView.addSubview(picImgView)
picImgView.center.x = imgView.center.x
picImgView.center.y = imgView.center.y-10
picImgView.layer.cornerRadius = picImgView.frame.width/2
picImgView.clipsToBounds = true
imgView.setNeedsLayout()
picImgView.setNeedsLayout()
// let newImage = imageWithView(view: imgView)
// return newImage
return imgView
}
//SHOW ON MAP
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: Double(lat)!, longitude: Double(long)!)
marker.iconView = self.drawImageWithProfilePic(urlString:getProviderImage,image: UIImage.init(named: "red")!)
Simple and easiest way to change icon. just replace these 3 icon (default marker.png) to your icon (1x,2x,3x).
In Google Cluster there was a problem with marker (icon) change.
This is the result I need to accomplish:
I need the icons with basic image: basket and additionally I need to put there UILabel with some text: once it is just a number, and once it is an amount to pay. Any ideas?
This is my example:
var image = UIImage(named: "cart")!
let text = "1 PLN"
UIGraphicsBeginImageContext(CGSizeMake(80, 50))
let context = UIGraphicsGetCurrentContext()
let label = UILabel(frame: CGRectZero)
label.text = text
label.font = UIFont.systemFontOfSize(10)
label.sizeToFit()
let width = max(label.frame.size.width + 10, 15)
let height = CGFloat(15)
CGContextSetFillColorWithColor(context, UIColor.greenColor().CGColor)
CGContextFillRect(context, CGRectMake(0, 0, image.size.width, image.size.height))
image.drawInRect(CGRectMake(80/2-50/2, 0, 50, 50))
let path = UIBezierPath(roundedRect: CGRectMake(75-width, 45-height, width, height), cornerRadius: 5)
path.lineWidth = 2
UIColor.redColor().setStroke()
UIColor.yellowColor().setFill()
path.stroke()
path.fill()
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = NSTextAlignment.Center
let attributes = [NSFontAttributeName: UIFont.systemFontOfSize(10.0), NSParagraphStyleAttributeName: paragraphStyle]
(text as NSString).drawInRect(CGRectMake(75-width, 45-height, width, height), withAttributes: attributes)
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
The result is following:
Some examples for different text:
