we have agreement our customers support current version plus 1 back. cannot drop ios 6 until ios 8 released. is possible use ios 7 enhancements , still support 6. love deploy 2 version of app or have runtime conditionals, however, not see how possible. you could. mean not knowing if it's possible? have wrap bunch of code in if() statements or preprocessor macros determine api availability, , maybe include corresponding xibs each version if necessary. people have been supporting previous ios versions long time. also want add, devices support ios6 support ios7. there minimal reason not add support ios7 fear of losing ios6 customers. ios5 capable devices can run ios6 well. ipad1 stuck on ios5, know. commenter stated 3gs , 4th gen ipod don't ios7. so really, it's not big deal drop support ios6 when 7 comes out, if targeting 6 anyway. you'll piss off jailbreakers , other people have use ota updates on 7.

i'm attempting teach myself audio programming in c# through online tutorials. i'm using wave files (*.wav) soundplayer. what confuses me this: why tutorials bother reading in , chopping wave file if we're going blindly feed soundplayer anyway ? i feel i'm missing gigantic conspiracy. trouble soundplayer simple, , need take more advanced control ?? thank in advance! fyi - tutorials i'm using are: http://www.codeproject.com/articles/7906/a-simple-c-wave-editor-part-1-background-and-analy http://blogs.msdn.com/b/dawate/archive/2009/06/24/intro-to-audio-programming-part-3-synthesizing-simple-wave-audio-using-c.aspx i'm not familiar soundplayer or c#, read audio files in parts avoid exhausting memory. allows start playback faster, since first part of file available in less time entire file.

i'm trying use vc++ (from visual studio 2012) complile projects qt creator 2.8. try create non-qt project in qt creator see says "cmake build". after steps (name of project, version control...) shows message: i have kit detected: how can solve problem? have cmake 2.8.11.2 installed. know can use mingw, need both x32 , x64 compilers, c++11 support (, nullptr, auto , on). know, cmake can generate vs's project files me, if need compile them rather often? creating *.sln , opening in vs, , compilong needed platform seems bit irrational me. or maybe there compiler suits needs (x32, x64, c++11)? you can use vc's compiler cmake projects fine. use "nmake makefiles" generator , build project invoking nmake . further improvement (at least large projects) use jom , using generator "nmake makefiles jom".

i added uibutton each uitableview row when nedd reloaddata, uibutton 0x0000. can give me suggestions? much. used code: - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath { /*nsstring *cellidentifier = [nsstring stringwithformat:@"%d,%d",indexpath.section,indexpath.row]; // nsstring *cellidentifier = @"cell"; uitableviewcell *cell = [_tableview dequeuereusablecellwithidentifier:cellidentifier]; if (cell == nil) {*/ nsstring *cellidentifier = [nsstring stringwithformat:@"%d,%d",indexpath.section,indexpath.row]; uitableviewcell *cell = [_tableview dequeuereusablecellwithidentifier:cellidentifier]; if (cell == nil) { cell = [[[uitableviewcell alloc] initwithstyle:uitableviewcellstylesubtitle reuseidentifier:cellidentifier] autorelease]; uilabel *pricelabel = [[uilabel alloc] initwithframe:cgrectmake(80, 0, 80, 30)]; pricelabel.backgroundcolor = [...
