Introduction to IOS Simulator features

In the run effect shown in Figure 1.38, the phone-like model you see is iOS Simulator. When you don't have an iphone or ipad device, you can use iOS Simulator to test the program. This is selected from the Xamarin iOS development combat .

IOS Simulator can mimic the functionality of a real iphone or ipad device, as shown in table 1-3.

Table 1-3 IOS Simulator

In the features shown in table 1-3, it is important to note that IOS Simulator can only implement these features, and other features are not implemented, such as making calls, sending SMS messages, acquiring location data, photographing, microphones, etc.

1. Back to Home

What if you want to exit the application shown in Figure 1.38 (a program designed to perform a specific function for a user is called an application)? At this point you need to select the "hardware | Home" command in the menu bar, the effect after exiting the application, 1.41 shows this article selected from the Xamarin iOS development combat .

2. Set the application's icon

As you can see in figure 1.41, when you exit the application, the icon for the application is a grid-like white icon, which is the default icon for iOS and is not used by the general developer, but instead uses the icon that you set. The steps to change the default icon are as follows:

(1) Return to the HelloWorld project, double hit open info.plist file, 1.42 is shown.

(2) Find the iOS 7 @2x under app icons, have an empty area above iOS 7 @2x, select it, pop up the Select File dialog, select an image file, click the Open button, and the selected image is shown in this blank area, 1.43.

Note: In app icons, there are three blank areas. Each blank area is different for iOS, and the content size of the display is different. The displayed content must go to meet the requirements of the blank area. For example, an empty area corresponding to IOS 7 @2x requires the contents of 120x120 to be displayed, and the selected image must be 120x120.

Click the Run button, and after the run effect exits the application, you can see the changed icon, as shown in 1.44.
