stringWithCString的内存泄漏

Question

嗨，我得到内存泄漏与以下代码行。如何解决....

const char *value = (const char *)sqlite3_column_text(statement, i);
[result setObject:[NSString stringWithCString:value encoding:NSUTF8StringEncoding] forKey:columnName];

或

const char *value = (const char*)sqlite3_column_text(statement, i);
NSString *str_Value = [[NSString alloc] initWithFormat:@"%@",[NSString stringWithUTF8String:value]] ;
[result setObject:str_Value forKey:columnName];
[str_Value release];

如何删除此泄漏。请帮助......

Answer 1

您需要null检查;

if (value != null)
{
   NSString *str_Value = [[NSString alloc] initWithFormat:@"%@",[NSString 
   stringWithUTF8String:value]] ;
  [result setObject:str_Value forKey:columnName];
}
