ios - Add shade gradient to the bottom of a uitableviewcell / uiimageview -


does know how add gradient bottom of uitableviewcell or uiimageview image shown below does?

enter image description here

add class project (swift):

class uigradientimageview: uiimageview {  let mygradientlayer: cagradientlayer   override init?(frame: cgrect){     mygradientlayer = cagradientlayer()     super.init(frame: frame)     self.setup()     addgradientlayer()  }   func addgradientlayer(){     if mygradientlayer.superlayer == nil{         self.layer.addsublayer(mygradientlayer)     }  }   required init(coder adecoder: nscoder){     mygradientlayer = cagradientlayer()     super.init(coder: adecoder)     self.setup()     addgradientlayer()  }   func getcolors() -> [cgcolorref] {     return [uicolor.clearcolor().cgcolor, uicolor(red: 0, green: 0, blue: 0, alpha: 0.5).cgcolor]  }   func getlocations() -> [cgfloat]{     return [0.5,  0.9]  }   func setup() {      mygradientlayer.startpoint = cgpoint(x: 0.5, y: 0)      mygradientlayer.endpoint = cgpoint(x: 0.5, y: 1)       let colors = getcolors()      mygradientlayer.colors = colors      mygradientlayer.opaque = false      mygradientlayer.locations = getlocations()  }   override func layoutsubviews() {     super.layoutsubviews()     mygradientlayer.frame = self.layer.bounds  } }

update: objective-c translated solution. credits @sleepsonnewspapers.

 #import "uigradientimageview.h"   @interface uigradientimageview()    @property (nonatomic, strong) cagradientlayer *mygradientlayer;   @end   @implementation uigradientimageview   -(instancetype)initwithframe:(cgrect)frame{   if(self){   self = [super initwithframe:frame];   self.mygradientlayer = [[cagradientlayer alloc]init];   [self setup];   [self addgradientlayer];   }  return self;  }   -(instancetype)initwithcoder:(nscoder *)adecoder{   if(self){    self = [super initwithcoder:adecoder];    self.mygradientlayer = [[cagradientlayer alloc]init];    [self setup];    [self addgradientlayer];   }   return self;  }   -(void)addgradientlayer{  if (self.mygradientlayer.superlayer == nil) {   [self.layer addsublayer:self.mygradientlayer];  } }

make uiimageview class on storyboard 1 instead of default.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
