Answer 3

试试我的自定义编码：您可以根据需要更改图像。

.h 文件

        //ProgressBar
            NSTimer *splashtimer;
            UIImage *ProgressBarBackgroundImage;
            UIImageView *ProgressBarLeft;
            UIImageView *ProgressBarRight;
            UIImageView *ProgressBarMiddle;
            UIImageView *LoadingBackground;

            NSInteger totalSizeOfProgressBarAnimation;
            NSInteger totalCountOfProgressBarAnimation;
            NSInteger NoOfPercentage;
            NSInteger startingvalue;
            int progressValue;


        //ProgressBar
        @property (nonatomic,retain) UIImageView *ProgressBarLeft;
        @property (nonatomic,retain) UIImageView *ProgressBarRight;
        @property (nonatomic,retain) UIImageView *ProgressBarMiddle;
        @property (nonatomic,retain) UIImageView *LoadingBackground;

        - (void) ProgressBarSizeCheck:(NSInteger)starting:(NSInteger)ending;

.m 文件

        @synthesize ProgressBarLeft,ProgressBarRight,ProgressBarMiddle,LoadingBackground;
        - (void)viewDidLoad {
            [super viewDidLoad]

            splashtimer = [NSTimer scheduledTimerWithTimeInterval: 0.75 target: self selector: @selector(startMoveProgress) userInfo: nil repeats: NO];

            ProgressBarLeft = [[UIImageView alloc] init];
            ProgressBarMiddle = [[UIImageView alloc] init];
            ProgressBarRight = [[UIImageView alloc] init];
            LoadingBackground = [[UIImageView alloc] init];
            ProgressBarBackgroundImage = [UIImage imageNamed: @"loaderbg.png"];
           [self.view addSubview: LoadingBackground];
        }

语用标记 -

        -(void)ProgressBarSizeCheck:(NSInteger)starting:(NSInteger)ending {
            startingvalue = starting;
            endingValue = ending;
            NoOfPercentage = ending - starting;

            if (startingvalue==0) {
                //ProgressBarLeft Image
                ProgressBarLeft.frame = CGRectMake(23,410,10,20);

                //ProgressBarMiddleImage
                ProgressBarMiddle.frame = CGRectMake(33,410,0,20);
                UIImage *ProgressBarImageMiddle = [UIImage imageNamed: @"loadercenterpart.png"];

            }

                [self moveDown:Duration:totalSizeOfProgressBarAnimation];
            }

        }
