Changing cursor color on UISearchBar without changing tintColor

Set your tint color to the color you want the cancel button to be and then use the UIAppearance Protocol to change the tint color on the text field to be the color you wish the cursor to be. Ex:

[self.searchBar setTintColor:[UIColor whiteColor]];                
[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setTintColor:[UIColor darkGrayColor]];
