Indent the text in a UITextField

This is the quickest way I’ve found without doing any subclasses:

UIView *spacerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 10)];
[textfield setLeftViewMode:UITextFieldViewModeAlways];
[textfield setLeftView:spacerView];

In Swift:

let spacerView = UIView(frame:CGRect(x:0, y:0, width:10, height:10))
textField.leftViewMode = UITextFieldViewMode.Always
textField.leftView = spacerView

Swift 5:

let spacerView = UIView(frame:CGRect(x:0, y:0, width:10, height:10))
textField.leftViewMode = .always
textField.leftView = spacerView
