@property (weak, nonatomic) IBOutlet UITextField *myTextField;


UIImageView * myImageView = [[UIImageView alloc]initWithFrame:CGRectMake(0.0f, 0.0f, 15, 15)];
myImageView.image = [UIImage imageNamed:@"myImage"];
[myTextField addSubView:myImageView];

the CGRectMake(0.0f, 0.0f, 15, 15)part lets you specify the position and size of your image (xPos, yPos, width, height)

该CGRectMake(0.0f, 0.0f, 15, 15)部分可让您指定图像的位置和大小(xPos, yPos, width, height)
