animation - Two picture loops after each other objective-c -

im trying create animation pictures using code:

nsmutablearray *imagearray = [[nsmutablearray alloc] initwithcapacity:22]; int i; (i =1; < 22; i++) { [imagearray addobject:[uiimage imagenamed:[nsstring stringwithformat:@"fbanimation%d.png", i]]]; //make animate self.fblogin.animationimages = [nsarray arraywitharray:imagearray]; self.fblogin.animationduration =0.8; self.fblogin.animationrepeatcount = 5; [self.fblogin startanimating]; } int j; nsmutablearray *imageloading = [[nsmutablearray alloc] initwithcapacity:4]; (j = 1; j < 4; j++) { [imageloading addobject:[uiimage imagenamed:[nsstring stringwithformat:@"loading%d.png", j]]]; //make animate self.fblogin.animationimages = [nsarray arraywitharray:imageloading]; self.fblogin.animationduration = 1; self.fblogin.animationrepeatcount = 5; [self.fblogin startanimating]; }

}

the problem either way i've tried far 1 animation gets executed on screen. want first animation run , sec "loading..." until other info facebook ready.

firstly, calling [self.fblogin startanimating] , resetting animationimages array each time go round each for loop. should move them outside loops - need start each animation once. secondly, sec loop executed after first, result expect sec animation appear, , not first. 1 way of getting round problem set code sec animation in separate method, , arrange called after first has finished calling:

[self performselector:@selector(animation2) withobject:nil afterdelay:durationofpreviousanimation];

at end of first for loop. i'm assuming since animation code we're guaranteed on main thread.

objective-c animation loops
