目标c:如何设置UIImageView图像

Question

海IAM新的objective c和iOS发展

设置UIImageview图像.尝试以下代码

arrowImgVw is UIImageView Class object

UIImage *image=[[UIImage alloc]init];
image=[UIImage imageNamed:@"return_journey_denoter.png"];
arrowImgVw.image = image;

Answer 1

嘿,你错了在某些方面使用这个代码将图像添加到UIImageView并在iPhone上显示它

UIImageView *myImage = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];

//分配imageView并设置其框架.

myImage.image = [UIImage imageNamed:@"return_journey_denoter.png"];

//将图像添加到imageview中

[self.view addSubview:myImage];

//将imageview添加到viewcontroller的视图中

Answer 2

只需将图像设置为imageView，只需一行代码

arrowImgVw.image = [UIImage imageNamed:@"return_journey_denoter.png"];
