How to create a dynamic UIImageView
提问by Jonathan
I want to create an UIImageView with, for example, "Trend.jgp" for a special case (if-condition). I tried various ways with CGRectMake but I am not able to create this picture dynamically to a special place. Furthermore, I can't use the function setimage like it's described in the Developer Documentation.
我想为特殊情况（if-condition）创建一个 UIImageView ，例如“Trend.jgp”。我用 CGRectMake 尝试了各种方法，但我无法将这张图片动态创建到一个特殊的地方。此外，我不能像开发人员文档中描述的那样使用 setimage 函数。
Has anyone got an idea how to realise my plan?
有没有人知道如何实现我的计划？

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Trend"]];
imageView.frame = CGRectMake(....) or imageView.center = CGPointMake(...)
Add this view to your container view, i.e. [myView addSubview:imageView];
将此视图添加到您的容器视图中，即 [myView addSubview:imageView];
回答by Jonathan
UIImageView *imageView = nil;
if (specialCase) {
imageView = [[UIImageView alloc] initWithImage: [UIImage imageNamed: @"Trend.jpg"]];
} else {
//whatever you want to do in the other case
}
