title: iphone simulator only shows the background images not the labels and text box, why is this?
body: <p>This is a simple iOS mobile app exercise. I have a image as a background, and then the labels and text box are added. I run the simulator and it shows correctly. but after a while I run the simulator again, the simulator only shows the background image, the text box and labels are not there anymore. I restart writing everything many time and the same thing happen at some point. This is driving me crazy. Did anyone know what is going on here??? Thank you so much in advance for your help!!!</p>
