主要用到NSOperation和NSOperationQueue实现动画队列

主要分三个类

animationManager :

\#import "YGPreGiftAnimationManager.h"

\#import "YGPreGiftAnimationOperation.h"

@interfaceYGPreGiftAnimationManager ()

@property (nonatomic,strong) NSCache \*operationCache;/// 操作缓存池

@property (nonatomic,  strong) NSOperationQueue \*serialQueue;//贵重礼物动画队列

@property (nonatomic,  copy)  YGPreGiftFinishBlock finishBlock;

@end

@implementation YGPreGiftAnimationManager

\- (void)showPreciousGiftAnimationWithGiftCount:(NSInteger)giftCount giftID:(NSInteger)giftID otherParamDict:(NSDictionary \*)otherParamDict bgImgView:(UIImageView \*)bgImgView animationView:(YGPreciousGiftAnimationView \*)animationView webpImgView:(YYAnimatedImageView \*)webpImgView finishBlock:(YGPreGiftFinishBlock)finishBlock \{

self.finishBlock = finishBlock;

WeakSelf(self);

for (int i = 0; i < giftCount; i ++) \{

NSString \*animatioKey = \[NSString stringWithFormat:@"%ld%@", (long)giftID, \[self getMsgId\]\];

YGPreGiftAnimationOperation \*animationOperation = \[\[YGPreGiftAnimationOperationalloc\] initWithAnimationView:animationView giftID:giftID otherParamDict:otherParamDict bgImgView:bgImgView webpImgView:webpImgView finishBlock:^\{

\[weakSelf.operationCache removeObjectForKey:animatioKey\];

if (weakSelf.finishBlock) \{

weakSelf.finishBlock();

\}\];

\[self.operationCache setObject:animationOperation forKey:animatioKey\];

\[self.serialQueue addOperation:animationOperation\];

//获取随机msgId

\- (NSString \*)getMsgId \{

NSDateFormatter \*formatter = \[\[NSDateFormatteralloc\] init\];

formatter.dateFormat       = @"yyyyMMddHHmmss";

NSString \*str              = \[formatter stringFromDate:\[NSDate date\]\];

NSInteger index            = (arc4random() % 900)  + 100;

return \[NSStringstringWithFormat:@"%@%@%ld", str, \[UserWrappershareUserWrapper\].UID, (long)index\];

//取消所有操作

\- (void)cancelAllAnimationOperation \{

\[self.serialQueuesetSuspended:YES\];

\[self.serialQueuecancelAllOperations\];

//贵重礼物动画队列

\- (NSOperationQueue \*)serialQueue \{

if (!\_serialQueue) \{

\_serialQueue = \[\[NSOperationQueuealloc\] init\];

\_serialQueue.maxConcurrentOperationCount = 1;

return\_serialQueue;

//操作缓存池

\- (NSCache \*)operationCache \{

if (\_operationCache==nil) \{

\_operationCache = \[\[NSCache alloc\] init\];

return\_operationCache;

@end

animationOperation :

\#import "YGPreGiftAnimationOperation.h"

@interfaceYGPreGiftAnimationOperation ()

@property (nonatomic, getter = isFinished)  BOOL finished;

@property (nonatomic, getter = isExecuting) BOOL executing;

@property (nonatomic, copy) YGPreciousGiftAnimationFinishBlock finishBlock;

@end

@implementation YGPreGiftAnimationOperation

@synthesize finished = \_finished;

@synthesize executing = \_executing;

\- (instancetype)initWithAnimationView:(YGPreciousGiftAnimationView \*)view giftID:(NSInteger)giftID otherParamDict:(NSDictionary \*)otherParamDict bgImgView:(UIImageView \*)bgImgView webpImgView:(YYAnimatedImageView \*)webpImgView finishBlock:(YGPreciousGiftAnimationFinishBlock)finishBlock \{

self = \[super init\];

if (self) \{

\_executing =  NO;

\_finished  = NO;

\_view = view;

\_giftID = giftID;

\_otherParamDict = otherParamDict;

\_bgImgView = bgImgView;

\_webpImgView = webpImgView;

\_finishBlock = finishBlock;

returnself;

\- (void)start
