NSArray causes EXC_BAD_ACCESS - objective-c

Question

I declare an NSArray in one class like this:
.h
#interface HTTP : NSObject {
NSArray *listOfProfiles;
}
#property (nonatomic, retain) NSArray *listOfProfiles;
.m
-(id) init {
if ((self = [super init])) {
listOfProfiles = [[NSArray alloc] init];
}
return self;
}
-(void) someMethod {
...
case GET_LIST_OF_PROFILES:
listOfProfiles = [result componentsSeparatedByString:#"^-^"];
NSLog(#"first break: %#",[listOfProfiles objectAtIndex:0]);
break;
...
}
I can access it here just fine, then when I try to access it in another class after creating an object I receive the error EXC_BAD_ACCESS and the debugger goes to main.m:
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
http = [[HTTP alloc] init];
[http createProfileArray];
profileListDelay = [[NSTimer alloc] init];
profileListDelay = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:#selector(profileListSelector) userInfo:nil repeats:YES];
}
- (void) profileListSelector
{
if (http.activityDone)
{
// http.listofprofiles mem leak?
for (int i = 0; i < http.listOfProfiles.count; i++)
{
NSLog(#"%#",[http.listOfProfiles objectAtIndex:i]);
}
[profileListDelay invalidate];
profileListDelay = nil;
}
}
I'm thinking it's a memory issue maybe, but I could be completely wrong.

Answer 1

It is a memory issue
It is in someMethod
-(void) someMethod {
...
case GET_LIST_OF_PROFILES:
listOfProfiles = [result componentsSeparatedByString:#"^-^"];
NSLog(#"first break: %#",[listOfProfiles objectAtIndex:0]);
break;
...
}
componentsSeparatedByString: returns an autoreleased object
Since you declared the array as a retain property, you should update it like so:
self.listOfProfiles = [result componentsSeparatedByString:#"^-^"];
