问题 I have a button which when pressed makes calls that load information from a series of URLs (about 5 seconds loading time). Right before actually making those calls I want to add a "loading" alert. When I use a UIAlertView the screen dims like it's about to pop up, but it doesn't until the data is loaded - too late!

问题 A method is called when a return button on the keyboard is pressed. After calling another method which returns an integer a message is created based on that integer. The message is then passed into an UIAlterView and displayed to the user. The alert doesn't have any options (hence why I'm not calling a delegate), but simply notifies the user of what happened.
