To display image from complete file path on device
在设备上显示来自完整文件路径的图像
NSString *path = @"<your file path>;
NSURL *url = [NSURL fileURLWithPath:path];
NSData *data = [NSData dataWithContentsOfURL:url];
imageView.image = [UIImage imageWithData:data];
*The key is using fileURLWithPathinstead of URLWithStringwhen converting to NSURL
*密钥正在使用fileURLWithPath而不是URLWithString转换为NSURL
