objective c - Constant crop aspect ratio using PEPhotoCropEditor library in iOS -

i'm using pephotocropeditor library in 1 of ios project. able having constant aspect ratio (1:1) following code.

- (void)openeditor {      pecropviewcontroller *controller = [[pecropviewcontroller alloc] init];     controller.delegate = self;     controller.image = self.imageview.image;      uiimage *image = self.imageview.image;        cgfloat width = image.size.width;     cgfloat height = image.size.height;     cgfloat length = min(width, height);      cgrectmake(cgfloat x, cgfloat y, cgfloat width, cgfloat height)     controller.imagecroprect = cgrectmake((width - length) / 2,                                           (height - length) / 2,                                           length,                                           length);   //     restricted square aspect ratio     controller.keepingcropaspectratio = yes;     controller.cropaspectratio = 1.0;      uinavigationcontroller *navigationcontroller = [[uinavigationcontroller alloc] initwithrootviewcontroller:controller];     [self presentviewcontroller:navigationcontroller animated:yes completion:null]; } 

but needed have aspect ratio (height:width) of (1:3) instead of (1:1).

controller.cropaspectratio = 1.0f / 3.0f; 

i tried above , nothing happened. still having same aspect ratio. change below code too.

controller.imagecroprect = cgrectmake((width - length) / 2,                                       (height - length) / 2,                                       length * 3,                                       length); 

again nothing happened. after commenting above hard coded value below.

controller.imagecroprect = cgrectmake(0.0f, 0.0f, 300.0f, 100.0f); 

then cropping area displayed correctly when resizing aria lead destroy crop aspect ratio (1:3)

any idea how remain aspect ratio (1:3) till editing process complete?

set in viewdidappear in pecropviewcontroller.m

 self.cropaspectratio = 1.0f;   self.keepingcropaspectratio = yes; 

and pass value function setkeepingaspectratio in pecroprectview.m

- (void)setkeepingaspectratio:(bool)keepingaspectratio {    _keepingaspectratio = keepingaspectratio;    if (self.keepingaspectratio) {      cgfloat width = cgrectgetwidth(self.bounds);      cgfloat height = cgrectgetheight(self.bounds);      self.fixedaspectratio = your_fixed_aspect_ratio_value;//fminf(width / height, height / width);    } } 

you expected result.
