Apple如何在短信中完成動畫GIF？

Question

我剛剛瞭解到，自iOS 5.0以後，您可以通過短信發送動畫GIF。

有誰知道Apple如何實現它，因爲UIImage和UIImageView不提供處理動畫GIF的開箱即用解決方案？

Answer 1

動畫UIImageView？

self.imgview_animation.animationImages = [NSArray arrayWithObjects: 
               [UIImage imageNamed:@"animation_1.jpg"], 
               [UIImage imageNamed:@"animation_2.jpg"], 
               [UIImage imageNamed:@"animation_3.jpg"], 
               [UIImage imageNamed:@"animation_4.jpg"], 
               [UIImage imageNamed:@"animation_5.jpg"], 
               [UIImage imageNamed:@"animation_6.jpg"], 
               [UIImage imageNamed:@"animation_7.jpg"], 
               [UIImage imageNamed:@"animation_8.jpg"], 
               [UIImage imageNamed:@"animation_9.jpg"], 
               [UIImage imageNamed:@"animation_10.jpg"],nil]; 

self.imgview_animation.animationDuration = 4; // seconds 
self.imgview_animation.animationRepeatCount = 1; // 0 = loops forever 
[self.imgview_animation startAnimating];
