Tool: Encrypting/Decrypting a password manually

Tuesday

Password Encryption/Decryption Tool:

This is the simple tool to encrypt or decrypt a password. By using this tool you just enter the input string(base64 strings) and click Encrypt/Decrypt button and you will get the corresponding output. Simply said this  a very useful tool for encrypt/decrypt base64 strings.

iPhone - Memory leak issues and solution

Saturday

Incorrect decrement of the reference count of an object that is not owned at this point by the caller:
                                                                                                               If you're try releasing an object returned from a property getter method, which in many cases would be the indication of a possible bug. To resolve this problem you can "release" the following way,
    
            [date release];
            date= nil;

               (OR)

   [date release], date= nil;

Argument in message expression is an uninitialized value:
              If you declare any variable without default value this error could be occur. To resolve this issue just you add a default value for your variable.
You can declared like...

       NSString *name = nil;
       NSString *date = nil;

Instead of

      NSString *name;
      NSString *date;

Receiver in message expression is an uninitialized value:
                                                                     You should initialize the value to nil when declaring it.

       personDetails *personInfo = nil;
Instead of
      personDetails *personInfo;


Logic error “Undefined or garbage value returned to caller:

                                                                 Assign default value of your string to nil; where you declared it.

NSString *title; should be changed as  NSString *title = nil;
