[英]iOS: How to dynamically add image to a parent view?
I've got a main image on the screen, and have an "overlay" UIView placed on top of it with the background color set to Clear Color. 我在屏幕上有一个主图像,并在其顶部放置了一个“覆盖” UIView,并将背景色设置为“清除颜色”。 I want to dynamically place other images inside the overlay view as follows:
我想动态地将其他图像放置在叠加视图内,如下所示:
UIImage* m_icon = [[UIImage alloc]initWithContentsOfFile:@"icon.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:m_icon];
[m_OverlayView addSubview:imageView];
But the icon image isn't showing up. 但是没有显示图标图像。 What am I missing?
我想念什么?
You may try: 您可以尝试:
NSString *icon_path = [[NSBundle mainBundle] pathForResource:@"icon" ofType:@"png"];
UIImage* m_icon = [[UIImage alloc]initWithContentsOfFile:icon_path];
UIImageView *imageView = [[UIImageView alloc] initWithImage:m_icon];
[m_OverlayView addSubview:imageView];
