Я пытаюсь создать изображение слайдера для просмотра 3 изображений в качестве слайдера. Но каждый раз он создает только одну картинку с тремя слайдами. Так, пожалуйста, где моя проблема?Проблема с печатью слайдера изображений?

Должен ли он печатать изображение в каждом слайде страницы?

Вы устанавливаете тот же кадр на три ImageView Изменение кадра, как указано ниже, вы получите три изображения в SlideView

UIImageView*iv_ = [[UIImageView alloc] initWithFrame:svrect_]; 
iv_.contentMode = UIViewContentModeScaleAspectFit; 
iv_.clipsToBounds = true; 
iv_.image = [UIImage imageNamed:@"images-1.jpg"]; 

svrect_.origin.x += iv_.frame.size.width; 

UIImageView*iv1_ = [[UIImageView alloc] initWithFrame:svrect_]; 
iv1_.contentMode = UIViewContentModeScaleAspectFit; 
iv1_.clipsToBounds = true; 
iv1_.image = [UIImage imageNamed:@"images-2.jpg"]; 

svrect_.origin.x += iv1_.frame.size.width; 

UIImageView*iv2_ = [[UIImageView alloc] initWithFrame:svrect_]; 
iv2_.contentMode = UIViewContentModeScaleAspectFit; 
iv2_.clipsToBounds = true; 
iv2_.image = [UIImage imageNamed:@"images-3.jpg"]; 

[_scrollview addSubview:iv_]; 
[_scrollview addSubview:iv1_]; 
[_scrollview addSubview:iv2_];
