ios - UIView animations canceling each other -

i have problem when playing multiple uiview animation blocks.

what have game lot of buttons, when press button spawns uilabel animates top of screen gets "added" total point amount, done using 3 nested blocks. works lets me spawn many point labels possible animations on them.

    //setup label     uilabel *pointindicator = [[uilabel alloc]initwithframe:cgrectmake(button.button.frame.origin.x, button.button.frame.origin.y, 60, 30)];     pointindicator.backgroundcolor = [uicolor clearcolor];     pointindicator.font = [uifont boldsystemfontofsize:25];     pointindicator.alpha = 0;     pointindicator.layer.shadowoffset = cgsizemake(1.0f, 1.0f);     pointindicator.layer.shadowopacity = 0.6;     pointindicator.layer.shadowradius = 1;      [pointindicators addobject:pointindicator];     [self.view addsubview:pointindicator];       cgpoint scorelabelposition = [self.view convertpoint:self.totalscorelabel.frame.origin fromview:self.totalscorelabel.superview];     cgsize scorelabelsize = [self.totalscorelabel.text sizewithfont:self.totalscorelabel.font];      [uilabel animatewithduration:0.3 delay:0 options:uiviewanimationcurveeasein animations:^{          //make label appear , move above button         cgrect frame = pointindicator.frame;         frame.origin.y -= 30;         pointindicator.frame = frame;         pointindicator.alpha = 1;      }completion:^(bool finished){           [uilabel animatewithduration:0.4 delay:0 options:uiviewanimationcurveeaseinout animations:^{              //move label next score label             nsinteger yposition = 0;             if ([uidevice currentdevice].userinterfaceidiom == uiuserinterfaceidiompad){                  yposition = 15;              }else{                  yposition = 2;             }             cgrect frame = pointindicator.frame;             frame.origin.x = scorelabelposition.x + self.totalscorelabel.frame.size.width/2 + scorelabelsize.width/2 + 5;             frame.origin.y = scorelabelposition.y - self.totalscorelabel.frame.size.height/2 + yposition;             pointindicator.frame = frame;          }completion:^(bool finished){              [uilabel animatewithduration:0.5 animations:^{                  pointindicator.alpha = 0;              }completion:^(bool finished){                  //animate point label increase bit in size                 cabasicanimation *pointanim = [cabasicanimation animationwithkeypath:@"transform"];                 pointanim.timingfunction = [camediatimingfunction functionwithname:kcamediatimingfunctioneaseineaseout];                 pointanim.duration = 0.1;                 pointanim.repeatcount = 1;                 pointanim.autoreverses = yes;                 pointanim.removedoncompletion = yes;                 pointanim.tovalue = [nsvalue valuewithcatransform3d:catransform3dmakescale(1.5, 1.5, 1.0)];                 [self.totalscorelabel.layer addanimation:pointanim forkey:nil];                  [pointindicator removefromsuperview];                 [pointindicators removeobject:pointindicator];             }];           }];      }]; 

however, when game ended buttons animate out of screen , image view grows in size out of middle, each using 1 animation block.

the problem if uilabel animating across screen @ same time game ends cancels button animation , growing image animation. if no uilabels spawned plays should. tried cancel , remove point labels before playing other animations, no luck. seems work if previous animations have been completed in advance. how remove them:

for(uiview *pointview in pointindicators){      [pointview.layer removeallanimations];     [pointview removefromsuperview]; } [pointindicators removeallobjects]; [self.totalscorelabel.layer removeallanimations]; 

all views animated subviews of same uiview. noticed if make point labels subviews of buttons animations can play @ same time.

i cant seem figure out behavior, there sort of conflict between animations?
