本文實例為大家分享了iOS全局跑馬燈制作方法，供大家參考，具體內容如下
思路：
1.創建一個單例
+ (instancetype)shareManager { static CCPaomaView *pModel = nil; static dispatch_once_t once; dispatch_once(&once, ^{ pModel = [[CCPaomaView alloc]initWithFrame:CGRectMake(0, 0, KScreenWidth, 0.0468 *KScreenHeight)]; }); return pModel;}2.把接收的數據存在本地的 plist，不適用于大量數據，每次讀取第一個數據，讀取完成刪除整個 plist，再把剩下的重新存進 plist
3.根據動畫代理，監聽動畫執行結束，將動畫實例置為 nil
- (void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag{ NSLog(@"%@",[self.paomaLabel.layer animationForKey:@"paoMaDeng"]); if ([self.paomaLabel.layer animationForKey:@"paoMaDeng"] == anim) { //移除第一組數據 [_array removeObjectAtIndex:0]; //移除整個 plist [CCPaomaModel removePaomaPlist]; //重新寫入 [_array writeToFile:[CCPaomaModel filename] atomically:YES]; //動畫停止之后，將實例置為 nil _pmAniamtion = nil; //數組為空之后移除跑馬燈 if (_array.count > 0) { [self showPaomaView:self.superview]; }else{ self.hidden = YES; [self removeFromSuperview]; } NSLog(@"%@",self.array); }}4.判斷動畫實例是否為空，使得切換界面，跑馬燈繼續，而不是重新開始
- (void)paomaAniamtion:(CGFloat)count{ //判斷動畫實例存不存在，存在繼續，不存在即創建 if (_pmAniamtion == nil) { _pmAniamtion = [CABasicAnimation animation]; _pmAniamtion.keyPath = @"transform.translation.x"; CGFloat W = CGRectGetWidth(_paomaLabel.bounds); _pmAniamtion.fromValue = @(W); _pmAniamtion.toValue = @(-W); _pmAniamtion.duration = _aniTime; _pmAniamtion.repeatCount = count; _pmAniamtion.removedOnCompletion = NO; //動畫結束不移除 _pmAniamtion.fillMode = kCAFillModeForwards; //動畫結束會保持結束的狀態 _pmAniamtion.delegate = self; //設置代理 [_paomaLabel.layer addAnimation:_pmAniamtion forKey:@"paoMaDeng"]; }else{ _pmAniamtion.repeatCount = count; }}5.切換界面，暫停、恢復動畫
#pragma mark -- 界面出現、消失，創建、恢復、暫停動畫- (void)viewWillAppear:(BOOL)animated { [_paomaView showPaomaView:self.view]; [_paomaView resumeAnimation];}- (void)viewWillDisappear:(BOOL)animated { [_paomaView pauseAniamtion];}話不多說，github 見代碼
