iphone-sdk-3.0

So, I read this post , and it's pretty much exactly what I was looking for. However... it doesn't work. I guess I'm not going to go with the singleton object, but rather making the array in either a Global.h file, or insert it into the _Prefix file. Both times I do that though, I get the error: Expected specifier-qualifier-list before 'static' and it doesn't work. So... I'm not sure how to get it to work, I can remove extern and it works, but I feel like I need that to make it a constant. The end goal is to have this Mutable Array be accessible from any object or any file in my project. Help

The problem of limiting strings that are directly entered into a UITextView or UITextField has been addressed on SO before: iPhone SDK: Set Max Character length TextField iPhone sdk 3.0 issue However now with OS 3.0 copy-and-paste becomes an issue, as the solutions in the above SO questions don’t prevent pasting additional characters (i.e. you cannot type more than 10 characters into a field that is configured with the above solutions but you can easily paste 100 characters into the same field).

So, changer your code to: @interface Routine : NSManagedObject { } @property (nonatomic) NSNumber * active; @implementation Routine

I want to show the UIView in full screen, but show the status bar, other things, like the navigation bar need to cover by the UIView . How can I do that ? dannywartnaby Struggling a little to fully understand the question, but I think you're asking how you can display a UIView above another view (so that the view with the navigation controls is completely hidden by the second view)? UIViewController has: - (void)presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated It would be wise to have your second view managed by a UIViewController , too. For the sake

When we resizing the image (after downloading and before storing that in document directory), by the following code: -(UIImage *)resizeImage:(UIImage *)image withSize:(CGSize)newSize { float actualHeight = image.size.height; float actualWidth = image.size.width; float imgRatio = actualWidth/actualHeight; float maxRatio = newSize.width/newSize.height; if(imgRatio!=maxRatio){ if(imgRatio < maxRatio){ imgRatio = newSize.width / actualHeight; actualWidth = imgRatio * actualWidth; actualHeight = newSize.width; } else{ imgRatio = newSize.height / actualWidth; actualHeight = imgRatio * actualHeight;
