Question

海IAM新的objective c和iOS發展

設置UIImageview圖像。試試下面的代碼

arrowImgVw is UIImageView Class object

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

Answer 1

你有written是OK的setting image的代碼，只是檢查name對於給定的圖像或者你可以嘗試下面的代碼...

UIIImageView *arrowImgVw = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,200,200)]; //just example change the frame as per your need  
arrowImgVw.image = [UIImage imageNamed:@"return_journey_denoter"]; 

Answer 2

嘿，你是錯在某些時候使用這個代碼在iPhone上添加圖片到的UIImageView並將其顯示devide

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

//清分ImageView的並設置其幀。

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

//添加圖片到imageview的

[self.view addSubview:myImage]; 

//添加ImageView的到你的ViewController的看法

在Swift3.0
