ios - UIImageView分配后未更改

Question

@property (weak, nonatomic) IBOutlet UIImageView *itemImage;

分配:

self.itemImage.image=[UIImage imageNamed:[item imageURL]];
NSLog(@"%@",[item imageURL]);
NSLog(@"%@",[UIImage imageNamed:[item imageURL]]);
NSLog(@"%@",self.itemImage.image);

结果:

2016-08-29 19:17:10.491 Calibration[7349:2878944] /var/mobile/Containers/Data/Application/C855E6A6-4787-4E96-9960-DA7BE37572BE/Documents/Q2ER004.png
2016-08-29 19:17:10.491 Calibration[7349:2878944] <UIImage: 0x150069d00> size {750, 560} orientation 0 scale 1.000000
2016-08-29 19:17:10.491 Calibration[7349:2878944] <UIImage: 0x150416c80> size {750, 560} orientation 0 scale 1.000000 

分配后，图像不会改变。
