Objective-C Tutorial - Lesson 23: Part 2: Coding the NSMutable Array

[BrazilianJ14]

You're a Christian??? That's so awesome so am I.

I'm following your tutorials along with the book as sometimes its nice to hear someone walk you through the exercises and point out little things and vice versa. for some reason my spendDollar method won't show up blue. When I delete and re-type it it gives me the (NSNumber*) suggestion and recognises euroTransaction as an NSNumber but then switches back to black . I also don't get any NSLogs when I save and run ..

[Wadoo925]

Can someone help me understand something? I am not copying the budget guide, but all I want to do is have an array and put it through a function. I have an array and successfully created that with two objects, but I need help creating the function.

Can anyone help?

Great videos by the way

Thanks, this has been great so far, but I must admit I am struggling to understand the 'why' on some of this one. I will watch it again, but for instance, you changed the type from NSNumber to double... can't figure out why you did that after telling us everything needed to be objects now. So I left it as is but can't get the program to compile. So either I just don't get the syntax or there was a reason for not using a NSNumber for spentDollars...

Congratulations, good job, continue like this :)

I just wanted to add, i have truly enjoyed the videos and I know how time consuming it can be. BIG THANK YOU!!! from someone who has little coding experience. Keep them coming.

I hope you can help....please

NSMutableArray *europeTransactions = [[NSMutableArray alloc] initWithCapacity:1];

[europeTransactions addObject:europeDollarTransact­ion];

[europeTransactions addObject:europeDollarTransact­ion2];

[europeBudget createBudget:1000.00 withExchangeRate:1.2500];

[europeBudget spendDollars:[europeTransactio­ns odjectAtIndex:0]]; [europeBudget spendDollars:[europeTransactio­ns objectAtIndex:1]]; warning: 'NSMutableArray' may not respond to '-odjectAtIndex:'

Thanks for taking the time to make all of these tutorials; they're AWESOME! I read the ObjC FD book and didn't have a strong understanding of some of the concepts. I ran across your tutorials a couple days afterwards and they have made all the difference; I have a much better understanding of ObjC now!

Looking forward to future tutorials! Thanks again!

i truly hope you make more videos, they truly dont get the views they deserve

[macandcomputerhelp]

@moldycode Don't worry I am going to continue them. I've just been busy with school and then my MacBook crashed on New Years Eve, and I didn't have it for most of January. A new one is coming very soon.

[moldycode]

@macandcomputerhelp Im truly thankful for the doors you have opened for me in objective c, but i must move on without you. lol. i will fall back on your tutorials when i need a hand =P

Just finished going through all 23 tutorials--thanks for doing that. I know that the views dwindled from 30,000 on the first lesson to only 733 on the 23rd due to weeding erbody out, but I wanted you to know that they were helpful and I think I am going to run through all of them again now (a lot of information--it often felt like I was drinking out of a firehose, but I enjoyed it).

I understand if making more ObjC tutorials isn't worth it for the views, but know that I'll watch them if you do.

[macandcomputerhelp]

@thelegume0oh Thanks for this comment! This isn't the last one at all. I have a couple in the making right now, and a new one is coming soon.

You found my favorite wallpaper lol!

[macandcomputerhelp]

@BRENNANSTECHBITE Yeah, I really like this wallpaper! It's one of my favorites too.
