Question

property type UIModalTransitionStyle is incompatible with type UIModalTransitionStyle inherited from UIViewController

Getting the above warning message after setting the property of UIModalTransitionStyle

@property (nonatomic, assign) UIModalTransitionStyle *modalTransitionStyle;
@synthesize modalTransitionStyle; 

This is simple property declaration

Have any ideas why getting this message

Answer 1

This is not the way you are supposed to use UIModalTransitionStyle.

Take a look at this property of UIViewController here:
http://developer.apple.com/library/ios/#documentation/uikit/reference/UIViewController_Class/Reference/Reference.html

Your code should be something like:

UIViewController *viewController = [[MyClass alloc] init];
viewController.modalTransitionStyle = UIModalTransitionStylePartialCurl;

According to UIViewController class reference UIModalTransitionStyle can be:

UIModalTransitionStyleCoverVertical
UIModalTransitionStyleFlipHorizontal
UIModalTransitionStyleCrossDissolve
UIModalTransitionStylePartialCurl
