Trouble with UIImage Touch tutorial

[drake]

I'm having a bit of trouble with the UIImage/Touch tutorial. I can't seem to get the image to show up on the iphone emulator. The tutorial creates the view programmatically, but I could not figure out how to get it to show up without the interface builder.

I can't even figure out how to stop the program from looking at MainWindow.xib. My code is exactly the same as in the tutorial yet I can't get an image to show up on my screen. it's pretty frustrating.

How do I stop the program from looking for MainWindow.xib?

Go into info.plist and delete MainWindow.nib at the bottom.

If you use a nib, add your views to the existing window.

if you don't use the nib then make sure to create a window and add subviews to it.

Thanks for such a prompt response! So now the program isn't looking for a MainWindow.xib, but the image still doesn't show up. I'm going to toy with it some more, but if you have any other suggestions, I am all ears. Thanks, again!

Also, when I'm at the UIImage/Touch tutorial page, the information bar on the right says that it has 22 comments, yet I could only see 5. Is there an extra comment page that I don't know about?

Hey, I am the creator of that tutorial, you could have just posted about this in the comments but whatever. All the videos have screwed up comment sections with large numbers so no, there is no extra page of comments . Unfortunately, that tutorial was made with SDK 3 or 4 where the MainWindow.xib was not really forced, just an option. Now in Beta 5 (if that's what you have) its more strict about calling the xib file. You should watch one of the newer tutorials I have made such as the Trash app in the intermediate section which sets up the imageViews in interface builder and can still handle touches. If you don't want to use interface builder then you should take a look at Spike099's tutorial in the intermediate section, called Custom Drawing. He goes over how to delete your MainWindow.xib from you project, if it still works in Beta 5. If all else fails just try to learn it with interface builder as thats what its gonna be in the final version of the iPhone SDK. Hope you enjoy all my tutorials and your welcome to ask more question by sending me an e-mail at Nitrex88@gmail.com

Hi Nitrex88! Thanks so much for your reply. I will definitely check out your other tutorials that work with the beta 5 release. Also, I could not figure out how to comment on your tutorial..which is why I used the forum. Sorry about that.

Also, this might already be common knowledge, but if there are any beginners out there, I found that if you don't want to use the MainWindow.xib file (and want to use one called "DifferentView.xib" for example), you can specify it in the appdelegate.m like so:

#import "YourAppDelegate.h"
#import "Controller.h"

@implementation YourAppDelegate

@synthesize window;
@synthesize YourController;

- (void)applicationDidFinishLaunchingUIApplication *)application {

//Specify the nib file to use
Controller *aController = [[Controller alloc] initWithNibName:@"DifferentView" bundle:[NSBundle mainBundle]];
self.YourController = aController;
[aViewController release];

UIView *controllersView = [YourController view]; //get view from view controller
[window addSubview:controllersView];
}

And make SURE that the View you create in Interface Builder is connected to the File Owner object. I spent awhile digging through everything before I realized my view wasn't connected to the right NIB. (yea, i'm sure you can tell that i'm new to this stuff.)

I got it to work in Beta5 by deleting MainWindow in Info.plist from the last line.

Also change your main.m main() to look something like this - replace the last 'nil' with the name of your app delegate.

int retVal = UIApplicationMain(argc, argv, nil, @"TouchesImageAppDelegate");
