iOS修改TextField占位符颜色大小

UITextField *addCtrolField = [[UITextField alloc]initWithFrame:CGRectMake(CGRectGetMaxX(rightTitleLableEND.frame) + 5, 5, FirstTwoView.width - rightTitleLableEND.width - 5, FirstTwoView.height - 10)];

addCtrolField.layer.borderColor = [UIColor blackColor].CGColor;

addCtrolField.layer.borderWidth = 0.5;

addCtrolField.textColor = [UIColor greenColor];

addCtrolField.textAlignment = NSTextAlignmentCenter;

addCtrolField.font = [UIFont fontWithName:boldgeshi size:22];

[FirstTwoView addSubview:rightTitleLableEND];

[FirstTwoView addSubview:addCtrolField];

//修改占位符内容

NSString *holderText = @"0.0000";

NSMutableAttributedString *placeholder = [[NSMutableAttributedString alloc]initWithString:holderText];

[placeholder addAttribute:NSForegroundColorAttributeName

value:[UIColor greenColor]

range:NSMakeRange(0, holderText.length)];

[placeholder addAttribute:NSFontAttributeName

value:[UIFont boldSystemFontOfSize:22]

range:NSMakeRange(0, holderText.length)];

addCtrolField.attributedPlaceholder = placeholder;
