DataCalculation: How to use User Defined Runtime Attributes in Xcode Interface Builder

Aug 05,  · This is useful in cases where one or many custom attributes are required by the application at runtime (e.g: the assembly attribute). While not ideal, disabling this single step is much better than disabling linking for the whole application. kitchencabin.cf uses a customized runtime and base class libraries (BCL) from Mono Commit e6f This sample demonstrates how to edit attributes of feature in a feature layer. Features in the map represent houses. Tap on a house to display the callout that contains information about the type of damage on that property. In order to change the type of damage, you tap on the information button in . May 30,  · The iOS runtime will set the value based on what you have defined in the runtime attributes. Sample UI. Here is a test UI that I put together to test our new runtime attributes. The gray rectangle is a UIView that we will add a border and shadow to. I also have a couple UISegmentedControls that we will customize later in this post.


Expanding User-Defined Runtime Attributes in Xcode


I am a Senior Software consultant at Atomic Object. Lately, I've been working on iOS projects. When building a user interface, I appreciate an IDE that allows me to easily change ios runtime attributes elements without having to write code.

Writing code for simple things like colors, borders, fonts, or shadows clutters my project. Fortunately, I work with talented designers at Atomic Object who can already use Xcode to make some of these aesthetic changes in the UI without needing to write extra code. However, while these designers can currently make selective changes to some controls, ios runtime attributes, not all of what they want to do is possible in the IDE. You tell it the name of the property you want to change then specify the type of the property and finally the value, ios runtime attributes.

If the property you want to change has a different type, then you have to write code to modify the property, ios runtime attributes. This is the problem, for example, when setting ios runtime attributes color on a border. With the help of an Objective-C category, you can get around this limitation and modify properties of different types.

The first example I will show you is how to change the border and shadow color of any UIView. You can extend classes in Objective-C using ios runtime attributes category. The IB stands for interface builder. I have to give these properties a unique name to avoid name conflicts with the original properties called borderColor and shadowColor that are of the type CGColor. The iOS runtime will set the value based on what you have defined in the runtime attributes.

Here is a test UI that I put together to test our new runtime attributes. The gray rectangle is a UIView that we will add a border and shadow to.

I also have a couple UISegmentedControls that we will customize later in this post. You can set these to any color value you want. I used black for the shadow and red for the border. I also set the borderWidthshadowOpacityshadowOffsetand cornerRadius to give you an example of what other properties you can modify using the runtime attributes feature. Please note that you will not see any changes to the UI in interface builder when you change the value of a property in the runtime attributes.

Your view will still look like a plain gray rectangle. These properties are set at runtime, so you have to run the simulator to see your changes at runtime. Next we will configure the font of a UISegmentedControl. The title font is more complicated to set because you can ios runtime attributes different text based on the selected state. We can use the same technique, using a category to extend UISegmented control, and change the font family and size with the runtime attributes and assume we are setting the title font for the normal state.

Now select one of the segmented controls and add the following runtime ios runtime attributes. You can select any color you want. My example is a bit ugly, but you get the point. You can now change all of these properties without having to modify code. If you would like to try this code out yourself to see it in action, I have the entire project on GitHub.

Using the same technique, can you think of other customizations to change at runtime for other controls?

Is there a way to make the segmented control look like 3d? If there is how? Is QuartzCore necessary for this to work? We're Hiring!

Active 7 years, 1 month ago. and very useful. and it does allow the use of user defined runtime attributes now in iOS. share | improve this answer. edited May 23 '17 at Oct 03,  · What is the mean by “User Defined Runtime Attributes”? “User Defined Runtime Attributes” are featured from Xcode 4 and iOS 5, great feature supported in interface builder. But bad thing is that most of the intermediate developers are not aware about it. Where can I found in Interface builder? take a look under Identity Inspector tab.
