给UItextFiled左侧设置小图片

给UItextFiled左侧设置小图片
创建类方法

+(void)setTextFiledLeftImage:(UITextField*)textFiled image:(NSString*)image{
    textFiled.leftViewMode=UITextFieldViewModeAlways;
    UIView * view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 30, 30)];
    UIImageView *imageview = [[UIImageView alloc]initWithFrame:CGRectMake(10, 5, 20, 20)];
    imageview.image = [UIImage imageNamed:image];
    [view addSubview:imageview];
    // 在文本框左侧预留一些空隙
    UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 5, 10, 20)];
    paddingView.backgroundColor = [UIColor clearColor];
    [view addSubview:paddingView];
    textFiled.leftView = view;
    textFiled.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;

    
}

直接类方法 调用即可
