UITextField 背景图像在 iOS 中不起作用

Question

I need to add background image in UITextField with left view mode also showing image. I have added both of them and its working. However my text content is stick to UITextField bottom. I need to give space between textfield and content.

Below is my code with image.

UITextField *textField = [UITextField new];
textField.borderStyle = UITextBorderStyleNone;
textField.background = [UIImage imageNamed:@"form-control.png"];
textField.translatesAutoresizingMaskIntoConstraints = NO;
textField.placeholder = @"Email/Phone no";
textField.font = [UIFont fontWithName:@"HelveticaNeue-Medium" size:16];

UIImageView *phoneImageView =[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 18, 21)];
phoneImageView.frame = CGRectInset(phoneImageView.frame, -5, 0);
[phoneImageView setImage:[UIImage imageNamed:@"phone.png"]];
[phoneImageView setContentMode:UIViewContentModeScaleAspectFit];
textField.leftView = phoneImageView;
textField.leftViewMode = UITextFieldViewModeAlways;

[self.view addSubview:textField];

Answer 1

you must set your textfield border-style square for keep image in your text-field as a background like this :

For Square:-

    [textfield setBorderStyle:UITextBorderStyleLine];

For set background image

  [textField setBackground:[UIImage imageNamed:@"imagename.jpg"]];

Answer 2

In my projects I've solved this by using a UIImageView for the background of the textfield, and using auto-layout to attach the UIImageView frame to match the frame of the UITextField. Once that's done, you can customize the margins between the textfield and the UIImageView by updating the constraints.
