UITextField特殊处理

UITextField特殊处理

1. 输入框左侧留白 

_textField.leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 0)]; //距离左侧10像素

_textField.leftViewMode = UITextFieldViewModeAlways;

2. 编辑时, 修改输入框右侧清空按钮clearButton背景色(或自定义)

UIButton *clearBtn = [_investCopiesTextField valueForKey:@"_clearButton"];

[clearBtn setImage:[UIImage imageNamed:@“imageName”] forState:UIControlStateNormal];

[clearBtn setImage:[UIImage imageNamed:@"imageName"] forState:UIControlStateHighlighted];
