UItextField相关代码如下:

- (UITextField *)textField{    if (_textField == nil) {        _textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 10, 300, 40)];        _textField.layer.borderColor = [[UIColor lightGrayColor] CGColor];        _textField.layer.borderWidth = 0.5;        _textField.layer.cornerRadius = 3;        _textField.leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 30)];        _textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;        _textField.leftViewMode = UITextFieldViewModeAlways;        _textField.clearButtonMode = UITextFieldViewModeWhileEditing;        _textField.font = [UIFont systemFontOfSize:15.0];        _textField.backgroundColor = [UIColor whiteColor];        _textField.placeholder = @"hello word!";        _textField.returnKeyType = UIReturnKeyDone;        _textField.delegate = self;    }        return _textField;}
