iphone - How to obtain UITextFields from a singleton -

In order to calculate in three view controllers, I need only four parameters. The parameters come in four scenes before UITextFields. I am not using global variables, but have developed a singleton class to enable the available parameters for each controller. I can reference the fine variable in the controllers, but I do not know how to start them. I have received the variable from the first view controller through a window developed with IB but there can be no way to get it in the earliest manner in singleton.

Thankfully appreciate the guidance and guidance.

There are several things that I'll change first, I'm a "globals Second, if I did, I would not collect UIView objects in the class designed to be "model" anytime. Thirdly, if I need to implement a singleton, then I will follow cocoa.

I need only four parameters to calculate in three view controllers.

And at the time, I suggest that you throw this class completely and think again about your design problem. Is it only you to store four NSString parameters (or NSNumber s or NSInteger s or float s) Need or ...)? If so, it is a full overkill to store the parameters inside a visual square. Simply create a simple class to store the parameters, whose title will look something like this:

@interface MyParameters: NSObject {NSString * someString; Nsnm * few numbers; NSInteger someInteger; Float some floats; } @property (nontomic, write) NSString * someString; @property (nontomic, rETAIN) nsnm * few numbers; @property (nanatomic, assign) NSINTEGER some integer; @protecti (nonatomic, assigned) float float; @end

I would like to migrate any object of this class to my application representative or my root view controller, and then I will pass it along with other view controllers which it has access to Required. Finally, I will use each visual controller, which will automatically get updates for any changes in the parameters if needed.
