ios - How to reduce the memory size of the image saved in Document Directory? -


i have made iphone app in download images via ftp & saved in document directory. these images of high memory size (approx. 2-3 mb).

then display these images in uitableview many rows & due these images allocation memory big & that's why app crashes.

so, need reduce memory size of these images.

how can this?

thanks,

make thumbnail of images before add them uitableview. in way size of images reduce drastically. use following code on uiimages picking document directory . 

uiimage *originalimage = ...; cgsize destinationsize = ...; uigraphicsbeginimagecontext(destinationsize); [originalimage drawinrect:cgrectmake(0,0,destinationsize.width,destinationsize.height)]; uiimage *newimage = uigraphicsgetimagefromcurrentimagecontext(); uigraphicsendimagecontext();

also have @ following links :-

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
