创建UIImageView

Question

如何在代码中创建UIImageView，而不是在我的xib文件中创建它？

Answer 1

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

容易馅饼！ ：d

您可能要检查苹果文档太： http://developer.apple.com/library/ios/#documentation/uikit/reference/UIImageView_Class/Reference/Reference.html

Answer 2

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(100, 7, 190, 23]; 
tabNameBackGround.image = [UIImage imageNamed:@"a.png"]; 
[self.view addSubview:imageView]; 

Answer 3

可以seperately创建一个UIImage，并从您的UIImage创建您的UIImageView。

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

然后，设置您的UIImageView

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

做任何你想要与你的图像的大小，但不要忘了将其释放。

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

Answer 4

答案到目前为止比他们需要更复杂的：initWithImage：“调整接收器的框架以匹配指定的图像大小”因此，所有你需要的是

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