following simple code resizing or crop image, need pass height or width image want:

for croped image:

uiimage *croppedimg = nil; cgrect croprect = cgrectmake(as need); croppedimg = [self croppingimagebyimagename:self.imageview.image torect:croprect]; 

use following method return uiimage (as want size of image)

- (uiimage *)croppingimagebyimagename:(uiimage *)imagetocrop torect:(cgrect)rect     {         //cgrect croprect = cgrectmake(rect.origin.x, rect.origin.y, rect.size.width, rect.size.height+15);          cgimageref imageref = cgimagecreatewithimageinrect([imagetocrop cgimage], rect);         uiimage *cropped = [uiimage imagewithcgimage:imageref];         cgimagerelease(imageref);          return cropped;     } 

here croped image return above method;

or resizing

and use following method specific hight , width image resizing uiimage:

+ (uiimage*)resizeimage:(uiimage*)image withwidth:(int)width withheight:(int)height {     cgsize newsize = cgsizemake(width, height);     float widthratio = newsize.width/image.size.width;     float heightratio = newsize.height/image.size.height;      if(widthratio > heightratio)     {         newsize=cgsizemake(image.size.width*heightratio,image.size.height*heightratio);     }     else     {         newsize=cgsizemake(image.size.width*widthratio,image.size.height*widthratio);     }       uigraphicsbeginimagecontextwithoptions(newsize, no, 0.0);     [image drawinrect:cgrectmake(0,0,newsize.width,newsize.height)];     uiimage* newimage = uigraphicsgetimagefromcurrentimagecontext();     uigraphicsendimagecontext();      return newimage; }
