Problem with isEqualToString: method and NSInteger - iphone

Question

This is my code:
for (int i=0; i<countingArray.count; i++) {
NSDictionary *element=[countingArray objectAtIndex:i];
NSString *source=[element objectForKey:#"id"];
NSInteger count= [[element objectForKey:#"count"] integerValue];
NSLog("source: %#",source); //Works
NSLog("count %d",count); //Don't Work! Error at this line
for(int c=0; c<subscriptions.count; c++) {
SubscriptionArray * element =[subscriptions objectAtIndex:c];
NSLog(#"sorgente sub %#",element.source);
NSLog(#"sorgente counting %#",source);
if([source isEqualToString:element.source]) {
element.count=count;
[subscriptions replaceObjectAtIndex:c withObject:element];
NSLog(#"equal");
//this part of code is never been executed but I'm sure that
//the if condition in some cases returns true
}
}
}
When I try to NSLog("count %d",count); my app crash without any information about.
I've also another problem with if([source isEqualToString:element.source]) I'm sure that some times the condition return true... How can I remove blank space? Like the trim function in php? thanks

Answer 1

Change:
NSString *source=[element objectForKey:#"id"];
NSInteger count= [[element objectForKey:#"count"] integerValue];
to:
NSString *source=[element valueForKey:#"id"];
NSInteger count= [[element valueForKey:#"count"] integerValue];
For removing blank spaces you can try:
NSString *trimmedString = [yourString stringByReplacingOccurrencesOfString:#" " withString:#""];

I didn't notice the first two NSLog statements. They're both of the form NSLog("something: %#", something). That is a C string literal, whereas NSLog takes an NSString for its format. This will lead to a crash. You want NSLog(#"source: %#", source).
