UITextField 搜索框满足你的需求,使用如下

参考源码

CoustomTextField \*textfieid = [[CoustomTextField alloc] initWithFrame:CGRectMake(0, 64, kScreenWidth, 28) leftViewMargin:10 textColor:[UIColor redColor] bgColor:[UIColor yellowColor] pholderText:@"请输入您要搜索的内容" leftViewImage:@"" rightViewImage:@""];

改变TextField LeftView,RightView间距

• (CGRect)borderRectForBounds:(CGRect)bounds;
• (CGRect)textRectForBounds:(CGRect)bounds;
• (CGRect)placeholderRectForBounds:(CGRect)bounds;
• (CGRect)editingRectForBounds:(CGRect)bounds;
• (CGRect)clearButtonRectForBounds:(CGRect)bounds;
• (CGRect)leftViewRectForBounds:(CGRect)bounds;
• (CGRect)rightViewRectForBounds:(CGRect)bounds;

实现方式

// 设置光标颜色

define TINTCOLOR [UIColor redColor]

@interface CoustomTextField ()
/** 左边间距 */
@property (nonatomic,assign) CGFloat leftMargin;
@end
@implementation CoustomTextField

// 左边view的 frame

• (CGRect)leftViewRectForBounds:(CGRect)bounds
  {
  CGRect iconRect = [super leftViewRectForBounds:bounds];
  iconRect.origin.x += self.leftMargin;
  return iconRect;
  }

• (CGRect)editingRectForBounds:(CGRect)bounds{
  CGRect editingRect = [super editingRectForBounds:bounds];
  editingRect.origin.x += 10;
  editingRect.size.width -= 2 * self.leftMargin;
  return editingRect;
  }

• (CGRect)textRectForBounds:(CGRect)bounds{
  CGRect textRect = [super textRectForBounds:bounds];
  textRect.origin.x += 10;
  return textRect;
  }

• (CGRect)rightViewRectForBounds:(CGRect)bounds{
  CGRect iconRect = [super rightViewRectForBounds:bounds];
  iconRect.origin.x -= self.leftMargin;
  return iconRect;
  }

• (CGRect)placeholderRectForBounds:(CGRect)bounds{
