iOS Need Help switching views...

[EducationApp]

I'm stuck on how to make it so the user has to click one button, and then a second for switching views. I'm trying to make it so the user can change the difficulty of the game, Easy, Medium, or Hard, and then press start to begin. How to I go about doing this. Is it an "if" statement. I've named the buttons btnButton1, btnButton2, btnButton3, btnButton4. Can you supply the code for me to switch views with just the easy option and then start?
The other views are imported as: easyview, mediumview, hardview.
Thanks

I know how to change views by clicking one button and then having it change but I'm stuck on how to have it so the Easy button + Ok goes to the Easy page and the medium button + ok goes to the medium button.
I have no idea where to go...

-(IBAction)switchviewid)sender {
easyview *easy = [[easyview alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:easy animated:YES];
}


-(IBAction)btnButton1id)sender
{
infoText.text = @"EASY: You have 10 rounds to complete and you are"
" given 60 seconds per round."
" Deal when ready...";
if (infoText.text == @"EASY: You have 10 rounds to complete and you are"
" given 60 seconds per round."
" Deal when ready...") {
-(IBAction)btnButton4 = switchview;
}
}
-(IBAction)btnButton4 = switchview doesn't work...

Please surround your code with

 tags so that we can read it, and post the entire code for the class you are having trouble with.

Didn't complete the if statement because when I put "-(IBAction)btnButton4 = switchview;" in, there is an error with the IBAction.

Which of your IBAction methods are actually hooked up to the button presses?

 

[EducationApp]

#import <UIKit/UIKit.h>

@interface thirdview : UIViewController {
    
    UILabel *infoText;
    IBOutlet UILabel *label;


}
-(IBAction)switchback:(id)sender;
-(IBAction)switchview:(id)sender;
-(IBAction)switchview1:(id)sender;

@property (nonatomic, retain) IBOutlet UILabel *infoText;

-(IBAction)btnButton1:(id)sender;
-(IBAction)btnButton2:(id)sender;
-(IBAction)btnButton3:(id)sender;
-(IBAction)btnButton4:(id)sender;

@end

 

[admanimal]

That code doesn't answer my question. I want to know which of those IBAction methods you have wired to the button presses in Interface Builder.

I'm going to assume that it's the btnButton1-4 ones that are wired to your four buttons. It looks like you want the code in the switchview method to execute after the code in btnButton1- so why not just put the code that is currently in the switchview method in btnButton1, or call the switchview method at the end of btnButton1?

P.S. You need to learn proper Objective-C naming conventions.

 

[EducationApp]

It is because the text shows up and they need to first press Easy, read the infoText, if they want to play that difficulty, "Deal" takes them there, if they want it harder, they go to Medium or Hard

 

[admanimal]

OK, I think I understand now. What IBAction is the Deal button wired to?

 

[EducationApp]

I'd like to start off with thanking you for helping me. The Deal button is btnButton4 which can be seen on the thirdview.m but I have not put it in the thirdview.h. All the switchviews go through it though.

 

[admanimal]

Well the concise answer to your question is that you should probably have an instance variable that stores the user's current difficulty selection, and when Deal is pressed, you will look at that variable and decide what view to load with an if or switch statement. This means you will only need 4 IBAction methods.
