IQKeyboardManager基本使用

IQKeyboardManager是iOS中专门管理UITextField/UITextView控件被遮挡的第三方库工具，并且简单易用

1.只要导入 #import "IQKeyboardManager.h"就可以使用，并且每个界面都有效

---

2.如果想让某个界面无效可以设置

- (void)viewWillAppear:(BOOL)animated{

    [super viewWillAppear:animated];

    [IQKeyboardManager sharedManager].enable = NO;

}

- (void)viewWillDisappear:(BOOL)animated{

    [super viewWillDisappear:animated];

    [IQKeyboardManager sharedManager].enable = YES;

}

---

3.当我们导入IQKeyboardManager后默认会在键盘上出现一个工具条

如果不想使用可以设置 [IQKeyboardManager sharedManager].enableAutoToolbar = NO;这样工具条就会消失。

4.如果想要更改键盘上的return键

//声明一个变量
@interface ViewController ()
{
    IQKeyboardReturnKeyHandler *returnKeyHandler;
}
@end

//在viewDidLoad中写入
returnKeyHandler = [[IQKeyboardReturnKeyHandler alloc] initWithViewController:self];
//这样键盘return会变成Next，只有当时最后一个时会变成return

---

5.点击背景键盘下去

- (void)viewDidLoad {
    [super viewDidLoad];

    [IQKeyboardManager sharedManager].shouldResignOnTouchOutside = YES;
}

---

6.如果视图有导航栏，上移View不想让UINavgationBar消失

1.如果你使用的是storyboard or xib，只需将当前视图视图控制器中的UIView class变为UIScrollView。

2.如果你使用的是代码，你就需要覆盖UIViewController中的-(void)loadView方法：

-(void)loadView
{
    UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.view = scrollView;
}

---

7.修改工具条上右侧的Done按钮

//设置为文字
[IQKeyboardManager sharedManager].toolbarDoneBarButtonItemText = @"完成";

//设置为图片
[IQKeyboardManager sharedManager].toolbarDoneBarButtonItemImage = [UIImage imageNamed:@"imageName"];

---

8.修改工具条上字体的颜色

[IQKeyboardManager sharedManager].shouldToolbarUsesTextFieldTintColor = NO;
    [IQKeyboardManager sharedManager].toolbarTintColor = [UIColor brownColor];

---

9.设置输入框与工具条的间距，默认为10.0f

[IQKeyboardManager sharedManager].keyboardDistanceFromTextField = 0.0f;

---

10防止IQKeyboardManager让rootview上滑过度,默认是YES

[IQKeyboardManager sharedManager].preventShowingBottomBlankSpace = NO;
