UILabel and NSString and floats...

[starwarsdevwookie59]

I have an app that starts in a table view, then loads the same page no matter which cell you choose.

That window then loads different numbers from my appdelegate, based on which cell you selected. For a rough example...

In my delegate

float address1;
float personselect;

In my rootviewcontroller

mainDelegate.personselect = indexPath.row +1;

In profileviewcontroller (this is what I'm trying to do)

NSString *tempstring = [NSString stringWithFormat:@"mainDelegate.address%.f", mainDelegate.playerselect];

[adresslabel setText:[NSString stringWithFormat:@"%.f", tempstring]];

So basically, I'm displaying a float that depends on a float, and I absolutely can not write out all of the if/then statements for it.

I obviously haven't gotten this to work, if there's anybody that understands what I'm trying to do and can help, I would highly appreciate it. thanks.

I think part of the issue is that the placeholder for a float should have a decimal inside it relating to the number of digits before and after the decimal point. such as %.3f would print however many before the decimal, and 3 digits after.

I'm pretty sure this is how it goes. If I am wrong, I apologize. But this is how it works for me, so just passing it along.

The first thing that jumps out at me is this declaration:

float *address1;
float *personselect;

The float type is a C intrinsic type, and when you want a float member in your class, it isn't normally declared as a pointer. I suspect the issue is that your declaration should look like this:

float address1;
float personselect;

I didn't really look at the rest of your code, so I'm sure if changing this will completely fix your problem.

I apologize... this is just a rough mockup of what I'm trying to do, I didn't mean to make those errors.

The code that puts the floats in the labels is all I am worried about. I just provided the other codes to show what I was working with.

Sorry.

Basically, I want to make the UILabel's text the value of mainDelegate.address@"%.f", mainDelegate.personselect.
