您可以使用动画来执行此操作，但为此您应该将其作为单个图像，如第一张图像所示，并制作具有不同位置的蓝色图像在圆圈中的不同图像。

loadingImageView.animationImages = [[NSArray alloc]initWithObjects:[UIImage imageNamed:@"circle1.png"],[UIImage imageNamed:@"circle2.png"],[UIImage imageNamed:@"circle3.png"],[UIImage imageNamed:@"circle4.png"],[UIImage imageNamed:@"circle5.png"],[UIImage imageNamed:@"circle6.png"],[UIImage imageNamed:@"circle7.png"],[UIImage imageNamed:@"circle8.png"],[UIImage imageNamed:@"circle9.png"],[UIImage imageNamed:@"circle10.png"],[UIImage imageNamed:@"circle11.png"],[UIImage imageNamed:@"circle12.png"],[UIImage imageNamed:@"circle13.png"], nil];

if(![loadingImageView isAnimating])
{
    loadingImageView.animationDuration=4;
    [loadingImageView startAnimating];

}

circle1.png,circle2.png,circle3.png...等是包含蓝色和红色图像作为一个图像的图像，蓝色图像在圆圈中的不同位置。现在希望对您有所帮助。如果有任何问题，请告诉我。
