Objective-C was invented by Brad Cox and Tom Love in the early 1980s. The company was called Stepstone. In 1988, Steve Jobs left Apple and formed company NeXT. NeXT licensed objective-c from Stepstone. After the acquisition of NeXT by Apple in 1996, objective-c has since become the programming language on Mac. Objective-C and Other Languages Objective-C is an strict superset of C, meaning any C programs can be compiled by a objective-c compiler. On the other hand, most recent gcc compilers has support for objective-C and should be able to compile objective-C code. Both being OO extension of C, C++ and objective-c are se...[more] 2 iPhone How to unlock IPhone How do I use tethering with an IPhone?

For example, if you have this in a /usr/local/sandbox/demo.sb (version 1) (allow default) (deny file-write*) (deny network*) and run sandbox-exec -f /usr/local/sandbox/demo.sb your-app-name, this means that the app can do anything but file-write and network communications 20 iPhoto Library size is huge, I removed all my pictures, but /User/MyName/Pictures/IPhoto Library is still 2 Gigabytes! First check your Trash folder in IPhoto, make sure it's empty. If it's empty and "iPhoto Library" file is still huge, make sure you don't have any pictures left, and then remove "iPhoto Library" file.

Right click (two-finger click) to enter setup interface, or (2) start your application, press fn+F8, then drag and drop your application into a specific space. To go into different spaces, (1) Fn+F8, go to different spaces, or (2) start application from any space, trigger task list (four finger swing), click specific application to go to that space This is specifically useful for virtual machines. For example, you could put VMware Fusion in a separate space, and put your VM into full screen mode, then you could have a full screen windows in one space, and a full screen OSX in another space. To switch, you could 4-finger swing, and click VMware Fusion icon, which will take you to that specific Space. 22 How do I use XCode auto completion? The default key stroke to bring out auto completion list is Option+Esx. I have yet to figure out how to pop up auto completion list automatically. 23 How do I bring up inspector windows in interface builder? Tools->inspector 24 How do snap a screenshop? Command+shift+3. [TC] 25 How do I enable hibernate on Mac OS? Use pmset command. Run the following to see if current setup "pmset -g", look for hibernationmode, it should be one of the following: hibernatemode takes a bitfield argument defining SafeSleep behavior. Passing 0 disables SafeSleep alto- gether, forcing the computer into a regular sleep. 1 (or 0001 bit 0) enables hibernation; causes OS X to write memory state to hibernation image at sleep time. On wake (without bit 1 set) OS X will resume from the hibernation image. Bit 0 set (without bit 1 set) causes OS X to write memory state and immediately hibernate at sleep time. 2 (or 0010 bit 1), in conjunction with bit 0, causes OS X to maintain system state in memory and leave sys- tem power on until battery level drops below a near empty threshold (This enables quicker wakeup from memory while battery power is available). Upon nearly emptying the battery, OS X shuts off all system power and hibernates; on wake the system will resume from hibernation image, not from memory. hibernatemode is set to 3 (binary 0011) by default on supported portables. hibernatemode is set to 0 (binary 0000) by default on supported desktops. Please note that hibernatefile may only point to a file located on the root volume. For newer Mac systems, there's also the following options[MS]: 5 (0101) - Behaves as 1 but applicable only for modern Mac that uses "Secure virtual memory". 7 (0111) - Behaves as 3 but applicable only for modern Mac that uses "Secure virtual memory". For example, "sudo pmset -a hibernatemode 5" or "sudo pmset -a hibernatemode 1" forces a windows-like hibernate every time you close your lid. Takes more time, but saves battery power. If you want to reset hibernate state, use "sudo pmset -a hibernatemode 3" 26 What is secure virtual memory? Secure virtual memory encrypts virtual memory swap files. By default, this feature is disabled. To enable it, go to System Pref->Personal->Security. 27 How do I put eclipse in my dock? Go to your eclipse diretory, drag and drop eclipse to the dock 28 VNC servers? Try vine server. 29 iTunes chinese character problem? Use 千千静听, select all songs, right click, and change tags to UTF16. 30 How do I update my system? Click system icon (the apple on our top left corner), select check update. 31 How do I print in black-and-white only? Click print..., then click preview, select "Quality and media", then click "gray scale printing". 32 How do I batch resize image? Use automator. Applications->Automator, on the left column, choose File and Finders, then pick Find Finder Items, drag it to right pane. Then drag Photos->Scale Photos to right side, run. 33 I cannot seem to access the hotel wifi with my Mac? This might have been caused by the hotel wifi server asking for a confirmation for agreement or payment. This usually shows up on windows when you first connect to network, but not always so on Mac. This is usually only a problem with DHCP server refusing to allocate you an IP address. To confirm if it is the issue, run "ifconfig" and check your ip address. If it is 169.254.x.x, then your are not getting a valid IP from the DHCP server. To work around this problem, run "tcpdump" from termical, look for broadcast packages, this usually contains your DHCP server address, for example, "192.168.2.1", "192.168.1.1", or "10.17.0.1", etc. Then open "Settings->Network->Airport", or click airport icon on Mac top bar, then click network properties, then select Airport->Advanced. Set a static IP in your network. Use google public DNS (8.8.8.8, and 8.8.4.4) as your primary and secondary DNS servers, try to connect again. 34 My macbook cann't seem to get dhcp IP address properly. I kept getting 169.254 addresses When macbook prompts you about accepting incoming traffic for configd and mDhcpd, answer yes 35 After upgrading to snow leopard, no sound? Check your bluetooth settings, try disable it and see if that helps. 36 How do I verify sha1 hash? /usr/bin/openssl sha1 /Users/test/Documents/1024SecUpd2003-03-03.dmg[APC] Comments References [APC]
