Question

I have a webservice and ios application. I use ASIHTTPRequest.h, ASIFormDataRequest.h headers to handle connection to my php scripts/mysql database

In one of the viewcontrollers I need to send multiple request to my web service and handle each response, and viewcontroller’s view and methods are needed to refresh after each request.

ASIHTTPRequest has only one (void)requestFinished:(ASIHTTPRequest *)request event so I need to handle my responses in blocks inside of (void)requestFinished:(ASIHTTPRequest *)request to handle the request I come up with idea that maybe I can use a string and when request finishes i can use this string in if statement I wrote following code , but my condition in my requestfinish method if ([checkRequest rangeOfString:@"like"].location != NSNotFound) doesnt work

VoteMe.h

@interface VoteMe : UIViewController<UITextFieldDelegate>{
 NSMutableString  *checkRequest;
}
@property (retain, nonatomic) NSMutableString  *checkRequest;

Vote.m

@synthesize checkRequest;
- (void)viewDidLoad
{
 [self showPicture];
}

-(void)showPicture
 {
     checkRequest =[NSMutableString stringWithString:@"showPicture"];

     //request a random picture url, from server
     NSURL *url = [NSURL URLWithString:showpicture];
     ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];

     [request setDelegate:self];
     [request startAsynchronous];
} 
-(IBAction)voteLike:(id)sender{

    checkRequest =[NSMutableString stringWithString:@"like"];

    NSURL *url = [NSURL URLWithString:voteup];
    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];

    [request setDelegate:self];
    [request startAsynchronous];

    [self showPicture];

}
- (void)requestFinished:(ASIHTTPRequest *)request
{    

    if ([checkRequest rangeOfString:@"like"].location != NSNotFound) {
     //do smth
     }

    if ([checkRequest rangeOfString:@"showPicture"].location != NSNotFound) {
    //do someth else
    }
}

The problem of above code when -(IBAction)voteLike:(id)sender is called it supposed to change string of checkRequest to “like” so when response of ASIFormDataRequest arrives if condition can work properly

In break points I see that checkRequest Variable is not a CFString

When I Use Nsstring instead of NSMutableString it is the same result

I know I need retain String then release afterwards but I Dont use alloc should I still need to retain/release

How can I achive my goal? Either a with better solution for checking if statement or fixing NSString and NSmutableString Issue above ?

Answer 1

When you define something as a property (checkRequest), use self.checkRequest when you refer to it in code unless you have a very good reason not to. Those attributes you put on the property statement get ignored if you access the variable directly.
