實(shí)現(xiàn)這樣的圓角效果

問題： leftview和rightView因?yàn)榍袌A角的原因 顯示不全。光標(biāo)也會顯示不全。

解決辦法 自定義UITextField 繼承UITextField

光標(biāo)顯示不全添加leftView

 UIView *view1 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 15 , 30 )];
  self.leftView = view1;
  self.leftViewMode = UITextFieldViewModeAlways;

leftview和rightview 向左邊或者右邊偏移

 -(CGRect)rightViewRectForBounds:(CGRect)bounds{
    CGRect iconRect = [super rightViewRectForBounds:bounds];
    iconRect.origin.x -= 15;
    return iconRect;
}

- (CGRect)leftViewRectForBounds:(CGRect)bounds{
    CGRect iconRect = [super leftViewRectForBounds:bounds];
    iconRect.origin.x += 15;
    return iconRect;
}
