Memory leak for NSDictionary loaded by plist file
- by Pask
I have a memory leak problem that just can not understand! Watch this initialization method:
- (id)initWithNomeCompositore:(NSString *)nomeCompositore nomeOpera:(NSString *)nomeOpera {
if (self = [super init]) {
NSString *pathOpere = [[NSBundle mainBundle] pathForResource:kNomeFilePlistOpere ofType:kTipoFilePlist];
NSDictionary *dicOpera = [NSDictionary dictionaryWithDictionary:
[[[NSDictionary dictionaryWithContentsOfFile:pathOpere]
objectForKey:nomeCompositore]
objectForKey:nomeOpera]];
self.nomeCompleto = [[NSString alloc] initWithString:nomeOpera];
self.compositore = [[NSString alloc] initWithString:nomeCompositore];
self.tipologia = [[NSString alloc] initWithString:[dicOpera objectForKey:kKeyTipologia]];
}
return self;}
Then this little variation (note self.tipologia):
- (id)initWithNomeCompositore:(NSString *)nomeCompositore nomeOpera:(NSString *)nomeOpera {
if (self = [super init]) {
NSString *pathOpere = [[NSBundle mainBundle] pathForResource:kNomeFilePlistOpere ofType:kTipoFilePlist];
NSDictionary *dicOpera = [NSDictionary dictionaryWithDictionary:
[[[NSDictionary dictionaryWithContentsOfFile:pathOpere]
objectForKey:nomeCompositore]
objectForKey:nomeOpera]];
self.nomeCompleto = [[NSString alloc] initWithString:nomeOpera];
self.compositore = [[NSString alloc] initWithString:nomeCompositore];
self.tipologia = [[NSString alloc] initWithString:@"Test"];
}
return self;}
In the first variant is generated a memory leak, the second is not! And I just can not understand why! The memory leak is evidenced by Instruments, highlighted the line:
[NSDictionary dictionaryWithContentsOfFile:pathOpere]
This is the dealloc method:
- (void)dealloc {
[tipologia release];
[compositore release];
[nomeCompleto release];
[super dealloc];}
