创建UIImageView

Question

如何创建UIImageView代码,而不是在我的xib文件中创建它？

Answer 1

你可以单独创建一个UIImage,并从你的UIImage创建你的UIImageView.

UIImage *myImage = [UIImage imageNamed:@"great_pic.png"];
UIImageView *myImageView = [[UIImageView alloc] initWithImage:myImage];

然后,设置UIImageView的大小

[myImageView setFrame:CGRectMake(0, 0, 100, 200)];

用你的形象做任何你想做的事,但不要忘记释放它.

[anotherView addSubview:myImageView];
[myImageView release];

Answer 2

UIImageView *someImageView = [[UIImageView alloc] initWithFrame:someRect];
someImageView.image = someImage;
[self.view addSubview:someImageView];

非常简单!:d

Answer 3

到目前为止，答案比所需的要复杂得多：initWithImage：“调整接收器的帧以匹配指定图像的大小。”因此，您所需要做的就是

UIImageView* v = [[UIImageView alloc] initWithImage: someImage];
