return a static const [] - iphone

Question

So in my model I have the following code... I am successfully able to return each individual value. I want to know how am I able to return the entire speakerTable []... Maybe some advice. Thanks!
typedef struct {
NSUInteger speakerID;
NSString * speakerName;
NSString * speakerPosition;
NSString * speakerCompany;
} SpeakerEntry;
static const SpeakerEntry speakerTable [] =
{
{0, #"name", #"position", #"company"},
{1, #"name", #"position", #"company"},
{-1, nil, nil, nil}
};
This works correctly...
-(NSString *) stringSpeakerCompanyForId:(NSUInteger) identifier{
NSString * returnString = nil;
if ([self helpCount] > identifier) {
returnString = speakerTable[identifier].speakerCompany;
}
return returnString;
}
This does not work at all..
-(id) getSpeaker{
//if ([speakerTable[0].speakerName isKindOfClass:[NSString class]])
// NSLog(#"YES");
NSArray * myArray3 = [NSArray arrayWithArray:speakerTable];
return myArray3;
}

Answer 1

arrayWithArray expects an NSArray, not a C array.
The first one works because you are using it like a C array.
Alternatively - don't use a struct, use an object instead:
Create a class called Speaker.
In Speaker.h
#interface Speaker : NSObject {}
#property (nonatomic, assign) NSUinteger id;
#property (nonatomic, copy) NSString name;
#property (nonatomic, copy) NSString position;
#property (nonatomic, copy) NSString company;
- (void)initWithId:(NSUInteger)anId name:(NSString *)aName position:(NSString *)aPosition company:(NSString *)aCompany;
#end
in Speaker.m
#import "Speaker.h"
#implementation Speaker
#synthesize id, name, position, company;
- (void)initWithId:(NSUInteger)anId name:(NSString *)aName position:(NSString *)aPosition company:(NSString *)aCompany {
if (!([super init])) {
return nil;
}
id = anId;
NSString name = [[NSString alloc] initWithString:aName];
NSString position = [[NSString alloc] initWithString:aPosition];
NSString company = [[NSString alloc] initWithString:aCompany];
return self;
}
- (void)dealloc {
[name release];
[position release];
[company release];
[super dealloc];
}
#end
And now in your calling code you can create an immutable array of speakers with:
Speaker *speaker0 = [[Speaker alloc] initWithId:0 name:#"name0" position:#"position0" company:#"company0"];
Speaker *speaker1 = [[Speaker alloc] initWithId:1 name:#"name1" position:#"position1" company:#"company1"];
Speaker *speakerNull = [[Speaker alloc] initWithId:-1 name:nil position:nil company:nil];
NSArray *speakerArray [[NSArray arrayWithObjects: speaker0, speaker1, speakerNull] retain]
[speaker0 release];
[speaker1 release];
[speakerNull release];
note: this is typed straight in, so feel free to mention/correct typos or errors

The method arrayWithArray takes in an NSArray as an argument, not a C array.
