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;
