Big time Leaking in Objective-C Category
- by Daniel Amitay
I created a custom NSString Category which lets me find all strings between two other strings. I'm now running into the problem of finding that there are a lot of kBs leaking from my script. Please see code below:
#import "MyStringBetween.h"
@implementation NSString (MyStringBetween)
-(NSArray *)mystringBetween:(NSString *)aString and:(NSString *)bString;
{
NSAutoreleasePool *autoreleasepool = [[NSAutoreleasePool alloc] init];
NSArray *firstlist = [self componentsSeparatedByString:bString];
NSMutableArray *finalArray = [[NSMutableArray alloc] init];
for (int y = 0; y < firstlist.count - 1 ; y++) {
NSString *firstObject = [firstlist objectAtIndex:y];
NSMutableArray *secondlist = [firstObject componentsSeparatedByString:aString];
if(secondlist.count > 1){
[finalArray addObject:[secondlist objectAtIndex:secondlist.count - 1]];
}
}
[autoreleasepool release];
return finalArray;
}
@end
I admit that I'm not super good at releasing objects, but I had believed that the NSAutoreleasePool handled things for me.
The line that is leaking:
NSMutableArray *secondlist = [firstObject componentsSeparatedByString:aString];
Manually releasing secondlist raises an exception.
Thanks in advance!
