iphone - Memory issues using ASIHTTPRequest or Image Resizing -


i can't tell i'm having memory issues uploading images server. after 10 or successful uploads memory warnings of level 1 next time quits due dateformatters or being out of memory. here code. uses asihttpdatarequest , image resize function. cant tell if request thats not being released or if image resizing function not releasing image. images huge photos taken phone @ normal high resolution resized print size , uploaded. somewhere along line i'm missing memory management somewhere , driving me mad!

i'm getting memory warnings after 10 or more uploads server using following code. there memory management specific asi i'm not using?

hi i'm using software i'm running huge memory issues. memory warnings , i'm not sure how clear them out without breaking upload. wondering if take @ code sample , maybe show me i'm doing wrong causes memory issue?

i think line

if(newimage == nil)      uigraphicsendimagecontext();

is not correct. uigraphicsendimagecontext() must invoked no condition.
