Passing Varibales Error

[Alexj17]

Hey All

Im getting this annoying error and tried every i know but in this case it hasnt helped.

I have in my delegate....

vid_name = [push objectForKey:@"vid"];

(in the console .... vid = "video" )

now in my normal page i have

NSString *videoName = [(MissileAppDelegate *)[[UIApplication sharedApplication] delegate] vid_name];
			
NSString *path = [[NSBundle mainBundle] pathForResource:videoName ofType:@"mp4"];

when i run this and it comes to play the video, i get an error that doesnt even relate to the video, it happens with all variables i try and pass over using the [push objectForKey:@"vid"];. if i just vid_name =@"video" it works fine.

Any Ideas?

Ok things to try:

1) Just before your line "NSString *path = [[NSBundle mainBundle] pathForResource:videoName ofType:@"mp4"];", debug and actually check the contents of "path". Does it look correct? Can you paste the path in your reply

2) Instead of passing "videoName" in the above line, hardcode it @"video". If this works then you definitely know it is a path issue (which is what the errors are suggesting)

3) I know its a stupid question but is the video.mp4 file actually in the bundle and does it match what you are passing in for its name i.e. case sensitivity etc.

1) If i put the debug arrow before this line then it doesnt run and cant see what value path is ??

2) This works

3) This works.

NSString *videoName = [(MissileAppDelegate *)[[UIApplication sharedApplication] delegate] vid_name];

****Variable is not a CFString at this time.

OK I've had a thought. Have you imported your appdelegate into your class.

i.e. #import "MissileAppDelegate.h"

[Alexj17]

Yeah, i have many other variables that work fine. they are just defined in the delegate by var = @"yeah"

its when i use the [push object....] thing it brakes.

its got to be something do with the wrong type of variable getting passed, CFString and NSString i dont know.

Ok, step over this line with the debugger and then hold your mouse over videoName and from the little pop up choose to print.

Also if you can print vid_name

The values will appear in the console. If they are black there's your problem.

Then what is being returned from your appdelegate is not a string and definitely can't be used as a path to your video.

What exactly does your "Push" dictionary store.

Basically all you want to do is to store the name of the video as a NSString in vid_name and use this to generate a path in order to load the video.

You definitely need to check out what is return from the push dictionary.

vid_name = [push objectForKey:@"vid"];
test356985 = vid_name;

Tell you what...send me a PM with details of where I can get your code and I'll take a look if you like. The forum isn't the best place for debugging :-)
