database in objective c november 19 2012 txcom2003 1 comment today i will show you how to access sqlite3 database with objective c i use xcode 4 4 1 first thing todo is to add sqlite3 library libsqlite3 dylib to framework directory in your project then write the interface file viewcontroller h import uikit uikit h import sqlite3 h interface viewcontroller uiviewcontroller sqlite3 db

november 3 2011 txcom2003 1 comment things need to be prepared tiny umbrella 5 00 12 greenpois0n 1 0 rc6 1 fixrecovery osx for 4 2 1 ios 4 2 1 ipsw follow this step make sure that you have backup shshs before open tinyumbrella and start tss server make sure that you see shshs for ios 4 2 1 in list all saved shshs enter dfu mode start itunes 10 1 restore ios 4 2 1 by pressing alt button and click restore button find and select ios 4 2 1 ipsw wait until itunes finish the process maybe there will be an error enter dfu mode run fixrecovery wait until iphone successfully reboot run greenpois0n done good luck categories iphone mac os iphone app dev tutorial 1 simple interaction with button and text august 21 2011 txcom2003 2 comments this tutorial show simple interaction with button and text i used xcode 4 1 create new project view based application 2 type product name here i typed buttonandtext 3 click file buttonandtextviewcontroller xib 4 drag and drop uibutton from object library to view and type button title for example ok 5 open header file buttonandtextviewcontroller h and add following code just add the bold text import uikit uikit h interface buttonandtextviewcontroller uiviewcontroller ibaction btnclicked id sender end 6 open implementation file buttonandtextviewcontroller m and type following code after implementation buttonandtextviewcontroller ibaction btnclicked id sender nsstring str nsstring alloc initwithformat welcome mr textname text uialertview alert uialertview alloc initwithtitle welcome message welcome mr tonny delegate self cancelbuttontitle ok otherbuttontitles nil alert show alert release 7 click file buttonandtextviewcontroller xib 8 while pressing control key click on the ok button and drag to the file s owner then select btnclicked 9 then try running the program the output should like this 10 let s add label and text field to view by drag and drop them from objects library then add import uikit uikit h interface buttonandtextviewcontroller uiviewcontroller iboutlet uitextfield textname property nonatomic retain uitextfield textname ibaction btnclicked id sender end 11 open implementation file buttonandtextviewcontroller m and type following code after implementation buttonandtextviewcontroller synthesize textname 12 change code for function ibaction btnclicked id sender ibaction btnclicked id sender nsstring str nsstring alloc initwithformat welcome mr textname text uialertview alert uialertview alloc initwithtitle welcome message str delegate self cancelbuttontitle ok otherbuttontitles nil alert show alert release str release 13 while pressing control key click on the file s owner and drag to the uitextfield then select textname 14 run the program try to type something in uitextfield then click ok button to test the output should like this note property nonatomic retain uitextfield textname means that you want the textname outlet to be expose as a property ibaction identifier is used to synchronize action methods synthesize keyword indicate that compiler will create getter and setter for the specific property the nonatomic keyword indicate that there is no need to ensure that the property is used in a thread safe manner because it is not used in multiple threads i also include the video how to do this in my facebook categories iphone mac os programming objective c basic knowledge may 30 2011 txcom2003 leave a comment this is small thing that i learned today while riding the train to buy some instant noodle in other town from the object oriented programming perspective there is some difference between objective c and and other languages such as that derived from simula like c java and c for non object operations objective c are identical with c in objective c we don t invoke a method but instead send a message invoking a method implies that you know something about that method while sending message leaves it up to the message to figure out what to do with it this make objective c loosely coupled that make it much more dynamic at runtime than simula derived languages in simula derived language you must know the type of an object before you can call the method while in objective c you simply send object with a message then the receiving object try to interpret that message in this case there is no guaranty of response if object doesn t understand the message it will return nil the other difference is in the way memory is managed in java there is garbage collection to handle memory management garbage collection frees the developer from manually managing the memory but it routine consume additional computing resource objective c using reference counting this is a form of garbage collection which count the number of reference to an object and frees the associate memory when the number of reference reach zero the main advantages of reference counting over classic garbage collection is that memory is freed as soon as it no longer in use almost objective c applications iphone apps uses model view controller mvc pattern rather than encouraging us to create subclass mvc make use of delegate classes mvc divide application into 3 functional pieces model manage the application state and associate data it s entirely decoupled from the ui or presentation of application state to the user view is what user sees and it displays the model for the user it allow user to manipulate it and respond and generate events controller coordinates update of the view and the model when user interaction make changes to the model and vice versa basic objective c syntax variable declaration look much same as other languages method call are surrounded by square bracket for example anobject somemethod the somemethod message is send to the anobject object anobject somemethod anotherobject the somemethode message is sent to the anobject object and passes anotherobject as an argument categories iphone
