objective-c cocoa cocoa-touch nsstring
I have an NSString like so:@”200hello”or @”0 something”What I would like to be able to do is take the first occuring number in the NSString and convert it into an int. So that @”200hello” would become int = 200.and @”0 something” would become int = 0.

objective-c lambda objective-c-blocks continuations structured-programming
When using methods which return blocks they can be very convenient. However, when you have to string a few of them together it gets messy really quicklyfor instance, you have to call 4 URLs in succession:[remoteAPIWithURL:url1 success:^(int status){[remoteAPIWithURL:url2 success:^(int status){[remoteAPIWithURL:url3 success:^(int status){[remoteAPIWithURL:url2 success:^(int status){//succes!!!}];}];}]; }];So for every iteration I go one level deeper, and I don’t even handle errors in the nested

objective-c sockets bsd-sockets
Ok, I have a problem with building a socket using Objective-C. If you’ll take a look at my code below, through help with example code and other sources, I was able to build a complete socket I believe. The problem is that when I compile it, it builds fine (no syntax problems), but there are no sockets being created. As you’ll notice I’ve commented out a lot of things in Server2.m and have isolated the problem to the very beginning when I create the struct for the listeningSocket. By the way, if

Hi everyone! It is my first post here.I am quite new in objective-c so maybe my question is not so hard but It is a problem for me.

To do that i’m trying to subclass NSImageRep but I don’t know how to create a proper bitmap for this file and how to draw it. Below is my code so far:header:@interface CTPWTPGMImageRep :

iphone objective-c uiscrollview
How can I force a UIScrollView in which paging and scrolling are on to only move vertically or horizontally at a given moment?My understanding is that the directionalLockEnabled property should achieve this, but a diagonal swipe still causes the view to scroll diagonally instead of restricting motion to a single axis.Edit: to be clearer, I’d like to allow the user to scroll horizontally OR vertically, but not both simultaneously.

I am new to Objective C so this code is probably not written that well. When the app is launched, it calls the following code if it has not been saved into the phone yet. When it starts to loop through the while loop, the app crashes on any phone the is not the iphone 5s. I think this is due to the memory usage. I believe that inside the while loop, when the NSMutableString (movieTitle) is created, is where the memory spike is. I should also add that the amount of times the loop is iterated is a
