iOS How to resize image at table view cell Swift
0
I work with multi platform application, and i have issues, i want that when app is load in iPad for that i want to change image size at tableview cell.
Now i have auto-layout:
I detect at which device app run use this code:
public extension UIDevice {
static let modelName: String = {
var systemInfo = utsname()
uname(&systemInfo)
let machineMirror = Mirror(reflecting: systemInfo.machine)
let identifier = machineMirror.children.reduce("") { identifier, element in
guard let value = element.value as? Int8, value != 0 else { return identifier }
return identifier + String(UnicodeScalar(UInt8(value)))
}
func mapToDevice(identifier: String) -> String { // swiftlint:disable:this cyclomatic_complexity
#if os(iOS)
switch identifier {
case "iPod5,1": return "iPod Touch 5"

My idea is, at table view
if modelName.range(of:"iPad") != nil
i want to change image size, for example 200x200;

You can use Auto layout for the same. Just create IBOutlet for the height and width constraint of ImageView.
public func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
//check for iPad and set the constraint values to 200*200
if modelName.range(of:"iPad") != nil
{
cell.imageViewHeightConstraint.constant = 200
cell.imageViewWidthConstraint.constant = 200
}
else
{
cell.imageViewHeightConstraint.constant = 100
cell.imageViewWidthConstraint.constant = 100
}
}
You can even do the same from storyboard by just selecting the height or width constraint and add another constant for iPad.
----Please check the below screenshots on how to add constant for iPad in storyboard.
1. Select the constraint. Click on + icon from right properties menu.
2. Select Compact compact for all types of iPad and add variation.
3. Set the constant value for iPad.

@qunzor I have updated my answer, please check. Also you need to increase the size of cell (if required).

Resizing your image will not affect your constraints. So you may want to update them aswell. for now-- you can resize images by doing so:
import UIKit
extension UIImage {
/// Returns a image that fills in newSize
func resizedImage(newSize: CGSize) -> UIImage {
guard self.size != newSize else { return self }
UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0);
self.draw(in: CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height))
let newImage: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
UIGraphicsEndImageContext()
return newImage
}
/// Returns a resized image that fits in rectSize, keeping it's aspect ratio
/// Note that the new image size is not rectSize, but within it.
func resizedImageWithinRect(rectSize: CGSize) -> UIImage {
let widthFactor = size.width / rectSize.width
let heightFactor = size.height / rectSize.height
var resizeFactor = widthFactor
if size.height > size.width {
resizeFactor = heightFactor
}
let newSize = CGSize(width: size.width/resizeFactor, height: size.height/resizeFactor)
let resized = resizedImage(newSize)
return resized
}
}
I'm still using this code in my apps. So rest assured
// Tests
guard let url = NSURL(string: "http://placehold.it/300x150") else { fatalError("Bad URL") }
guard let data = NSData(contentsOfURL: url) else { fatalError("Bad data") }
guard let img = UIImage(data: data) else { fatalError("Bad data") }
let outImageFit = img.resizedImageWithinRect(CGSize(width: 200, height: 200))
let outImageFill = img.resizedImage(CGSize(width: 200, height: 200))

@qunzor I have updated my answer, please check. Also you need to increase the size of cell (if required).

You can use Auto layout for the same. Just create IBOutlet for the height and width constraint of ImageView.
public func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
//check for iPad and set the constraint values to 200*200
if modelName.range(of:"iPad") != nil
{
cell.imageViewHeightConstraint.constant = 200
cell.imageViewWidthConstraint.constant = 200
}
else
{
cell.imageViewHeightConstraint.constant = 100
cell.imageViewWidthConstraint.constant = 100
}
}
You can even do the same from storyboard by just selecting the height or width constraint and add another constant for iPad.
----Please check the below screenshots on how to add constant for iPad in storyboard.
1. Select the constraint. Click on + icon from right properties menu.
2. Select Compact compact for all types of iPad and add variation.
3. Set the constant value for iPad.

Resizing your image will not affect your constraints. So you may want to update them aswell. for now-- you can resize images by doing so:
import UIKit
extension UIImage {
/// Returns a image that fills in newSize
func resizedImage(newSize: CGSize) -> UIImage {
guard self.size != newSize else { return self }
UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0);
self.draw(in: CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height))
let newImage: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
UIGraphicsEndImageContext()
return newImage
}
/// Returns a resized image that fits in rectSize, keeping it's aspect ratio
/// Note that the new image size is not rectSize, but within it.
func resizedImageWithinRect(rectSize: CGSize) -> UIImage {
let widthFactor = size.width / rectSize.width
let heightFactor = size.height / rectSize.height
var resizeFactor = widthFactor
if size.height > size.width {
resizeFactor = heightFactor
}
let newSize = CGSize(width: size.width/resizeFactor, height: size.height/resizeFactor)
let resized = resizedImage(newSize)
return resized
}
}
I'm still using this code in my apps. So rest assured
// Tests
guard let url = NSURL(string: "http://placehold.it/300x150") else { fatalError("Bad URL") }
guard let data = NSData(contentsOfURL: url) else { fatalError("Bad data") }
guard let img = UIImage(data: data) else { fatalError("Bad data") }
let outImageFit = img.resizedImageWithinRect(CGSize(width: 200, height: 200))
let outImageFill = img.resizedImage(CGSize(width: 200, height: 200))
