Design Code Execute

Below is the code to call a number within a function.

I've tested this call function on both the iphone and ipod. The iphone opens a UIAlert and prompts the user to call or cancel. The ipod ignores the call without causing a crash (same as the simulator)

To have a UILabel print out a price float with 2 decimal places you'll want to cast a string with to except a float with 2 decimal places.

A Frequent Problem with ie6: The bottom of the text (e.g. g y p) get cut off and make text illegible. This mostly happens with two line breaks and can be fixed by using a larger line-height in css.

To fix the problem we are going to create a class using the internet explorer 6 box hack.

We need to locate the exact area that we are having the problem with. For me the text was being cut off at .description h4 a

To fix the text cut off issue without the box hack just simply created a css class and adjsut the line-height

After updating the iPhone in iTunes to Software OS 3.0.1 I was unable to access it through the xcode organizer. After reinstalling the newest xocde (failed) and some digging I found a line of code you need to copy and paste into your terminal once, restart xcode, and you have access to pushing onto the iphone again.

Open up Terminal, copy below, paste and enter into terminal, restart xcode.

One of my CoreData applications started acting buggy, and was spitting out a huge error dump on app close in the debug console. The errors spitting out didn't tell me anything but CoreData Error 1560 and 1570. Upon inspection I found on google that another layer of errors is stored in the CoreData foundation. On Stack OverFlow found a very useful function but re-wrote it because

was causing an error.

Add this into you applicationWillTerminate function in your Application Delegate

The cause of Error in my CoreData Application was an Attribute in my xcdatamodel file. An optional field was checked as indexed and not optional. The simple action of unchecking indexed and checking optional fixed a whole mass of errors.

A quite useful button for a navigation controller with a deep stack would be a home button. It is simple to add.

In your RootViewController viewDidLoad Function

That will add a home button in to top right of your navigation controller

Create a function called go home in your rootViewController

This function will pop your view controller to its root view

An iPhone Application we recently produced had a order form on it. We needed to create a function that would run through all our UItextFields, extract their values, loop through, alert the user if a UITextField wasn't completed, and execute a function (our ajax request) if all checks out.

What 's involved in this function

• alertview - a pop up that lets the user know they missed a required field
• array - a list of all the UITextField values
• int - a variable that increment everytime time a UITextField Checks out
• for loop - Loops through the Array
• if statement - Check the array count to the increment count

This function assumes you know a bit about the iphone, have declared and linked your IBOutlet UITextFields, and have linked your submit button in the Interface Builder to  -(void)textFieldCheck:(id) sender; (which would be declared in your header file).
