objective c - Gif animation from 383 .gif's -


i've created gif animation in adobe flash, wanna import in xcode put app. have 383 gif images (frames), , have written code create smoothly flow animation:

#import "viewcontroller.h" #define image_count       383     @interface viewcontroller ()  @end  @implementation viewcontroller     - (void)viewdidload {              [super viewdidload];      //////////////////       // build array of images, cycling through image names     (int = 0; < image_count; i++)      imageview.animationimages = [[nsarray alloc]initwithobjects:[uiimage imagenamed:                                [nsstring stringwithformat:@"picollage00%d.gif", i]],nil];       imageview.animationrepeatcount = 5;     [imageview startanimating];       // additional setup after loading view, typically nib. } 

the images , images counting picollage0383.gif

enter image description here

in code semantic error: start image picollage000.gif should picollage0001.gif, shouldn't it?
changed using if-clauses , condition in for-loop.

#import "viewcontroller.h" #define image_count 383  @interface viewcontroller () @end  @implementation viewcontroller  - (void)viewdidload {     [super viewdidload];     nsmutablearray *imagearray = [[nsmutablearray alloc] initwithcapacity:0];     // start image picollage0001.gif     (int = 1; <= image_count; i++)         if (i < 100)             if (i < 10)                 [imagearray addobject:[uiimage imagenamed:[nsstring stringwithformat:@"picollage000%d.gif", i]]];             else [imagearray addobject:[uiimage imagenamed:[nsstring stringwithformat:@"picollage00%d.gif", i]]];         else [imagearray addobject:[uiimage imagenamed:[nsstring stringwithformat:@"picollage0%d.gif", i]]];      // assuming `animationimages` nsarray     imageview.animationimages = [imagearray copy];     imageview.animationrepeatcount = 5;     [imageview startanimating]; } 

above tested code (the loop) , generates correct filenames , stores initialized uiimages in nsmutablearray.

note: depending on how large gifs might bad idea (huge memory allocations) put images in array. if slow animation should load images before need them , dealloc them after using them immediately.
