在以下情况下,我有内存泄漏。我每 30 秒读取一次数据,使用 SBJSONParser 将其转换为字典,添加通知,然后使用数据将其绑定到 tableview:
// Read data and send notification
-(void)onSocket:(AsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag
{
NSString *content = [[NSString alloc] initWithData:[data subDataWithRange:NSMakeRange(0, [data length] - 2)] encoding: NSUTF8StringEncoding];
// Line where leaks appear
NSMutableDictionary* dict = [[NSMutableDictionary alloc] initWithDictionary:[content JSONValue]];
[content release];
// Post notification
[[NSNotificationCenter defaultCenter] postNotificationName:@"BindData" object:nil userInfo:dict];
[dict release];
}
在 CustomViewController 我有观察者:
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(bindData) name:@"BindData" object:nil];
和 bindData 方法:
-(void)bindData:(NSNotification*)notification
{
NSAutoreleasePool* pool = [[NSAutoReleasePool alloc] init];
NSMutableArray* customers = [notification.userInfo objectForKey:@"Customers"];
for (NSDictionary* customer in customers)
{
Company* company = [[Company alloc] init];
company.name = [customer objectForKey:@"CompanyName"];
NSLog(@"Company name = %@", company.name);
[company release];
}
[pool drain];
}
问题是:当我设置 company.name = 该字典中的某些内容时,我在线上出现内存泄漏: NSMutableDictionary* dict = [[NSMutableDictionary alloc] initWithDictionary:[content JSONValue]]; 自从我每 30 秒阅读一次以来,它一直在增加。
感谢您提供的任何帮助。谢谢。
