i want in image uiactivity indicator

you can create custom alert follow (ps: had developed custom alert after 3 hours of working, compatible iphone4, iphone5 , ipad ):

-(void)showalert{   alertviewview = [[uiview alloc]initwithframe:self.window.frame];  uiimageview *alertbackground = [[uiimageview alloc]initwithframe:cgrectmake(-200, -200, self.window.frame.size.width*2, self.window.frame.size.height*2)]; //   alertbackground.image = [uiimage imagenamed:@"alertbackground.png"]; [alertviewview addsubview:alertbackground];  alertbackground.backgroundcolor = [uicolor blackcolor]; alertbackground.alpha = 0.5; uiimageview *alertimage = [[uiimageview alloc]initwithframe:cgrectmake(self.window.frame.size.width/2-310/2, self.window.frame.size.height/2-179/2, 310, 248)]; alertimage.image = [uiimage imagenamed:@"rommanalertbig.png"]; [alertviewview addsubview:alertimage];[alertbackground release];[alertimage release];           uibutton *lbutton = [uibutton buttonwithtype:uibuttontypecustom];         lbutton.frame = cgrectmake(self.view.frame.size.width/2-150+40-15, self.view.frame.size.height/2-179/2+118 , 120, 41);          [lbutton settitle:@"cancel" forstate:uicontrolstatenormal];         [lbutton addtarget:self action:@selector(removealert) forcontrolevents:uicontroleventtouchupinside];         [alertviewview addsubview:lbutton];           uibutton *rbutton = [uibutton buttonwithtype:uibuttontypecustom];         rbutton.frame = cgrectmake(self.view.frame.size.width/2-150+170-15, self.view.frame.size.height/2-179/2+118 , 120, 41);          [rbutton settitle:@"ok" forstate:uicontrolstatenormal];         [rbutton addtarget:self action:@selector(yesaction) forcontrolevents:uicontroleventtouchupinside];         [alertviewview addsubview:rbutton];      uilabel *lbl = [[uilabel alloc]initwithframe:cgrectmake(self.window.frame.size.width/2-310/2+30, self.window.frame.size.height/2-179/2+75, 260, 40+69)]; lbl.text = @"description"; lbl.textcolor = [uicolor whitecolor]; lbl.textalignment  =uitextalignmentcenter; lbl.numberoflines = 0; lbl.font = [uifont systemfontofsize:17.0]; lbl.backgroundcolor = [uicolor clearcolor]; [alertviewview addsubview:lbl];[lbl release];  [self.window addsubview:alertviewview]; alertviewview.alpha = 0; [uiview animatewithduration:0.1 animations:^{alertviewview.alpha = 1.0;}];  alertviewview.layer.transform = catransform3dmakescale(0.5, 0.5, 1.0);  cakeyframeanimation *bounceanimation = [cakeyframeanimation animationwithkeypath:@"transform.scale"]; bounceanimation.values = [nsarray arraywithobjects:                           [nsnumber numberwithfloat:0.5],                           [nsnumber numberwithfloat:1.1],                           [nsnumber numberwithfloat:0.8],                           [nsnumber numberwithfloat:1.0], nil]; bounceanimation.duration = 0.3; bounceanimation.removedoncompletion = no; [alertviewview.layer addanimation:bounceanimation forkey:@"bounce"];  alertviewview.layer.transform = catransform3didentity;   }   -(void)removealert{ (uiview *v in [alertviewview subviews]) {     [v removefromsuperview]; } [alertviewview removefromsuperview]; [alertviewview release];   }  -(void)yesaction  { [self removealert]; // code here  }
