Question

NSString *title = [myWebView 
                   stringByEvaluatingJavaScriptFromString:@"document.title"];
NSMutableArray *array = [[NSMutableArray alloc] initWithCapacity:8];  
int j = 0;
int i=0;
int count=0;   
int len;
len = [title length];

for(i=0;i<len;i++){
    NSString *c = [title substringWithRange:NSMakeRange(i, 1)];

    if([c isEqualToString:@","])
    {
        //array[count]= [title substringWithRange:NSMakeRange(j, 2)];
        NSString *xxx = [title substringWithRange:NSMakeRange(j,(i-j))];
        NSLog(xxx);

        //insert the string into array
        [array insertObject:xxx atIndex:count];
        j=i;
        count = count + 1;
    }

}

My app always crashes at the line

[c isEqualToString:@","]

and gives the error – Thread1 : Program received signal: “SIGBART”.

I know for sure that the problem is occurring while comparing strings since the app runs if I remove that one line of code.

Can someone please help? Thanks

Consider using:

- (NSArray *)componentsSeparatedByString:(NSString *)separator

Example:

NSString *title = [myWebView stringByEvaluatingJavaScriptFromString:@"document.title"];
NSMutableArray *array = [title componentsSeparatedByString:@","];
