It has been designed with the iOS Photos app editor in mind, and as such, behaves in a way that should already feel familiar to users of iOS. Each framework is separate; you do not need to import both. Follow the remaining steps on Getting Started with Carthage to finish integrating the framework.

Simply create a new instance passing the UIImage object you wish to crop, and then present it modally on the screen. Optionally, TOCropViewController also supports a custom presentation animation where an already-visible copy of the image will zoom in to fill the screen.

While traditional cropping UI implementations will usually just have a dimming view with a square hole cut out of the middle, TOCropViewController goes about its implementation a little differently.

Since there are two views that are overlaid over the image A dimming view and a translucency viewtrying to cut a hole open in both of them would be rather complex. Instead, an image view is placed in a scroll view in the background, and a copy of the image view is placed on top, inside a container view that is clipped to the designated cropping size.

The size and position of the foreground image is then made to match the background view, creating the illusion that there is a hole in the dimming views, and minimising the number of views onscreen. Skip to content.

The choice of having the controller return the cropped image to a delegate, or immediately pass it to a UIActivityViewController.Posted on June 28, by Steven Lipton. Almost every iPhone and iPad now has a camera. Many people want to use a camera in their apps for various reasons. While you may not be building the next Instagram or Twitter, there are many places where photo documentation comes in handy.

There are two ways to use the camera. The more powerful and advanced method is using AVFoundationbut it is also a very complicated way to get a photo out of the camera. The simpler way is the UIImagePicker. It is also the best way to fetch photos from the photo album. We will be using a dab of auto layout as well.

If you want a brief introduction to auto layout go over and take a look at my book Practial Autolayout. Make a new project SwiftPizzaCam with a single view and using Swift. As already mentioned, make the device Universal. Xcode 8 come with a series of easily accessible preview modes in interface builder. Right-click and save the image below:. Click on Assets. Xcassets and drag the pizza file into the assets folder.

Go back to the story board and select the clip icon. You will find the pizza media there. Click the pin button. Click off Constrain to Margins.

Be sure to press tab after you type in any number in this popover. In the properties change the View Mode to AspectFit to properly size the photo. Change the text of the label to read Pizza Cam!!! Using the pin menuPin it to the bottom, left and right like this, again updating the frames:. Add a bar button item and a flexible space bar item to the toolbar. In one of the two bar buttons label it Photo and the other Library. Your tool bar and layout should look like this:. If you did everything correctly, you should have no auto layout warnings.

If you do, go to the resolver and click Update Frames on the bottom half of the menu that appears. If things get messier after doing this, clear the constraints on the bottom of the resolver, and pin everything again. Your next step is to wire up all the outlets and actions. Open the assistant editor.

This is important for stuff we will do later.In this swift tutorial, you are going to learn how to build a custom UITableView programmatically using Swift 4. Along the way, I am going to be showing you how to create a custom UITableViewCell programmatically from scratch as well.

If you are new to building programmatic UI in Xcode, take a look at this article which covers how to create a simple login screen programmatically. Then, choose a single view application and name it contactsapp and leave all other settings as is. Once the project is created, download the asset files in here and unzip it, then drag them into the Assets.

Xcassets file. Storyboard is not needed for this project. If you want to keep the Main. In that case, you can skip the next two sections and jump right into Step 4: Create a Data Model. At this stage, the Xcode does not have an entry point, meaning the project does not have a root view controller that it points to, which will normally appear first followed by the splash screen when you run the app.

However, doing it manually will help you to understand the steps involved in the same process. When adding the root view controller manually, Xcode will set its background colour to black by default. I am going to create two files as part of the model for our app, which are Contact. Go ahead and create the contact. This file contains a simple Contact Struct that will have a few properties in it based on the final table view cell image below.

I will be setting the profile image reference names to the same as names so that I do not have to create a property for the profile image. In real-world applications, all the API calls code would go there. Create a static method called getContacts inside the ContactAPI class which is responsible to get all of the contacts data. Create a property called contacts and assign the value, which would be an array of contact objects, by invoking getContacts method on ContactAPI, like the code below.

Note: As you can see, I use static keyword in front of the getContacts methods when declaring it so that I do not have to instantiate ContactAPI class to invoke getContacts method. Go to contactsViewController. The numberOfRowsInTableView method determines how many rows UITableViewCells it should create and display in the table view, which would be based on the length of the model array contacts.

Inside this method, declare a variable called cell by invoking the dequeReusableCell on the tableView passing identifier string and indexpath.

Choosing Images with UIImagePickerController in Swift

This identifier string will be used to register this cell for contactsTableView later. Get the name property from the contact object on each iteration using indexPath.

At this point, contactsTableView does not know about this cell. Note: If you change the identifier string insidecellForRowAtIndexPath, you should come back to the code above and change it there as well.

But the content of tableview is overlapping with the status bar at the top and with the horizontal bar at the bottom which are outside of the safe area. Left and right are absolute to the screen, on the other hand, leading and training will be based on the reading direction of the text. Run it and you can see the content does not go beyond the non-safe areas which are highlighted with red like in the screenshot below. Go to AppDelegate. Create a method called setUpNavigation inside contactsViewController file and invoke it inside the viewDidLoad method.

Rather than using the default UITableViewCell, I am going to create a custom cell to match the final output design like the image below. This property is instantiated with UIImageView inside closure aka anonymous function. The main reason for containerView is to add both labels to it and to center them vertically against the content view of the cell. In the first line, profileImageView will be set vertically centered using centerYAnchor against its parent view self.

All the auto layout constraints are set. I could directly set all the labels and image view inside cellForAtIndexPath method, instead, passing the data to the view and letting it present it would be a clean approach in my opinion. As you can see, I have created a computed property with an observer called didSet. The code inside didSet observer will be executed every time contact property is set.We need to give it a few options before actually presenting it.

First, we need to set our view controller as the delegate for the UIImagePickerController, to handle a few events. So, make your viewDidLoad look like this:.

How to find an aspect fit image’s size inside an image view

We should set whether the imagePicker wants to allow editing, and we definitely need to set the sourceType property. SourceType, which gives 3 options:. What are the differences between photoLibrary and savedPhotosAlbum?

Basically, photoLibrary gives the user access to any of their photos available on the device, with albums, overall view, and camera roll. The savedPhotosAlbum is pretty much just that, the images saved locally to your device, but no access to albums or any of the other views.

The camera one is rather self explanatory. It lets you have the camera as the imageSource. Now, if you really want, you could run this app, and it will show the image picker as advertised.

We just want the image, so that is what we ask for. InfoKey are:. So, if we did allow editing, we could get to that image there. The next line is not strictly-speaking necessary, but without it, the picture will come in and fill as much of the UIImageView as it can, and ignore its normal aspect ratio. ScaleToFill, hence it filling the area as much as it can. This one is similar to a way to fit widescreen movies on a TV called Pan and Scan.

The next line of course just sets the image of the UIImageView to be the image we just got pack. This is analogous to setting the text property of a UILabel to the Swift String that you want to show. It will dismiss without this in iOS 8, it seems, but Apple encourages dismissing it yourself. Screenshots taken from Xcode 6.

You can also use your own page indicator by adopting the PageIndicatorView protocol. Position of the page indicator can be configured by assigning a PageIndicatorPosition value to the pageIndicatorPosition property on ImageSlideshow. You may specify the horizontal and vertical positioning separately. Horizontal positioning options are:. Vertical positioning options are:. By default activity indicator is not shown, but you can enable it by setting DefaultActivityIndicator instance to Image Slideshow:.

There's also an option to use your own activity indicator.

See ActivityIndicator. There is also a possibility to open full-screen image view using attached FullScreenSlideshowViewController. The simplest way is to call:.Image views let you efficiently draw any image that can be specified using a UIImage object. You can configure image views programmatically or in your storyboard file and change the images they display at runtime.

For animated images, you can also use the methods of this class to start and stop the animation and specify other animation parameters. An image view uses its content Mode property and the configuration of the image itself to determine how to display the image. It is best to specify images whose dimensions match the dimensions of the image view exactly, but image views can scale your images to fit all or some of the available space.

If the size of the image view itself changes, it automatically scales the image as needed. The UIView. Content Mode.

For a resizable image with cap insets, those insets affect the final appearance of the image. Specifically, cap insets define which parts of the image may be scaled and in which directions.

For more information on creating resizable images with cap insets, see UIImage. Similarly, any further transparency in the background of the image is dependent on the transparency of the image view and the transparency of the UIImage object it displays.

When the image view and its image both have transparency, the image view uses alpha blending to combine the two. If the image does not have an alpha channel, the alpha value of each pixel is assumed to be 1. An image view can store an animated image sequence and play all or part of that sequence.

You specify an image sequence as an array of UIImage objects and assign them to the animation Images property. Once assigned, you can use the methods and properties of this class to configure the animation timing and to start and stop the animation.

All images in the sequence should have the same size. When scaling is required, the image view scales each image in the sequence separately. If the images are different sizes, scaling may not yield the results you want.

All images in the sequence should use the same content scale factor. Make sure the scale property of each image contains the same value. Image views ignore user events by default. Normally, you use image views only to present visual content in your interface. If you want an image view to handle user interactions as well, change the value of its is User Interaction Enabled property to true. After doing that, you can attach gesture recognizers or use any other event handling techniques to respond to touch events or other user-initiated events.

To maximize performance of your image view code, consider the following tips:. Cache scaled versions of frequently used images.Post a Comment. Home About Contact. Post Top Ad. Swipe Gesture Recognizer is the one of the important gesture for the iOS users.
