摘要
I added a custom PNG icon for the Refresh button to the project, setting the UIButton type to Custom and the image to point at my refresh icon (you will need to drag your icon into your Xcode project before it will be available as a custom image). I resized the Refresh button to be the same size as the Info button provided by the template, setting the View Mode to "Scale to Fill" in the Attributes tab of the Inspector window. When connecting the UIButtons to the received actions——for example, when dragging the refresh View: action to the Refresh button——choose Touch Up Inside from the drop-down menu of events that Interface Builder will present to you when you make the connection. With this number of UI elements to play with, it's going to be easy to get confused. What's more, we are not going to connect all of the labels to our code, as some of them aren't going to be updated (e.g., section headers and the “Temp:”, “Humidity:”, and “Wind:” labels). So, for the elements you will connect to an IB0utlet, use the Identity Inspector's Interface Builder Identity section to change the Name attribute of the element to be the same as the variable in the Main View Controller interface file. Figure 7-11 shows the assignments. While this doesn't make it easier to connect the outlets to the UI elements, it does make it easier to check whether we've made an incorrect connection. If you click on File's Owner and switch to the Connections tab of the Inspector window, as Figure 7-12 shows, you can quickly check that each outlet is connected to the correct UI element since the name on each side of the connection should be the same. Although we've written the interface for the view controller and built and connected our view to the interface, we haven't implemented it yet. Let's hold off on that until we've built our data model. ……
