9.17.1. An important method ¶
- (id)initWithImage:(UIImage *)image
- (id)initWithImage:(UIImage *)image highlightedImage:
(UIImage *)highlightedImage
- (void)startAnimating
- (void)stopAnimating
9.17.2. Add a custom method addImageView ¶
-(void)addImageView{
UIImageView *imgview = [[UIImageView alloc]
initWithFrame:CGRectMake(10, 10, 300, 400)];
[imgview setImage:[UIImage imageNamed:@"AppleUSA1.jpg"]];
[imgview setContentMode:UIViewContentModeScaleAspectFit];
[self.view addSubview:imgview];
}
Add another custom method addImageViewWithAnimation ¶
This method explains how to animate images in imageView.
-(void)addImageViewWithAnimation{
UIImageView *imgview = [[UIImageView alloc]
initWithFrame:CGRectMake(10, 10, 300, 400)];
// set an animation
imgview.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:@"AppleUSA1.jpg"],
[UIImage imageNamed:@"AppleUSA2.jpg"], nil];
imgview.animationDuration = 4.0;
imgview.contentMode = UIViewContentModeCenter;
[imgview startAnimating];
[self.view addSubview:imgview];
}
注意: 我们必须添加命名为”AppleUSA1.jpg”和”AppleUSA2.jpg”到我们的项目,可以通过将图像拖到我们导航区域,其中列出了我们的项目文件所做的图像。
Update viewDidLoad in ViewController.m, as shown below
(void)viewDidLoad
{
[super viewDidLoad];
[self addImageView];
}
