如何更改textField的placeholder的左边距以及颜色字号等

 

UITextField *tfPhone           = [[UITextField alloc] init];

tfPhone.leftView               = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 15, 40)];

tfPhone.leftViewMode           = UITextFieldViewModeAlways;

self.tfPhone                   = tfPhone;

tfPhone.delegate               = self;

tfPhone.backgroundColor        = UIColorFromRGBWithAlpha(0xd5d5d5, 1.0);

        

NSMutableParagraphStyle *style = [tfPhone.defaultTextAttributes[NSParagraphStyleAttributeName] mutableCopy];

        

style.minimumLineHeight        = tfPhone.font.lineHeight - (tfPhone.font.lineHeight - [UIFont systemFontOfSize:14].lineHeight) / 2.0;

        

tfPhone.attributedPlaceholder  = [[NSAttributedString alloc] initWithString:@"请输入您的手机号" attributes:@{NSParagraphStyleAttributeName : style, NSFontAttributeName : [UIFont systemFontOfSize:14], NSForegroundColorAttributeName: UIColorFromRGBWithAlpha(0x878787, 1.0)}];

        

tfPhone.textColor              = UIColorFromRGBWithAlpha(0x878787, 1.0);

[self addSubview:tfPhone];

tfPhone.layer.cornerRadius     = 5;

tfPhone.layer.masksToBounds    = YES;
