0119——UIImageView的一些属性 和 简单动画实现

1.contentMode

view.contentMode = UIViewContentModeScaleAspectFill;

2.是否实现触摸

3.简单实现动画 图片的名字为campFire01-campFire17

NSMutableArray * imagearray = [NSMutableArray array];

for (int i = 1; i<=17; i++) {

//拼接图片的名字

NSString *name = [NSString stringWithFormat:@"campFire%@%d",i<10?@"0":@"",i];

//NSString *name = [NSString stringWithFormat:@"campFire%02d",i];

UIImage * image = [UIImage imageNamed:name];

[imagearray addObject:image];

}

UIImageView * view = [[UIImageView alloc]initWithFrame:CGRectMake(40, 40, 320-80, 568-80)];

view.contentMode = UIViewContentModeScaleAspectFit;

view.animationImages = imagearray;//直接接受数组

view.animationDuration = 2;//时间

view.animationRepeatCount = 0;//重复多少次 0表示无数次

[view startAnimating];
