IQKeyboardManager基本使用

IQKeyboardManager是iOS中專門管理UITextField/UITextView控件被遮擋的第三方庫工具，並且簡單易用

1.只要導入#import "IQKeyboardManager.h"就可以使用，並且每個界面都有效

---

2.如果想讓某個界面無效可以設置

- (void)viewWillAppear:(BOOL)animated{

    [super viewWillAppear:animated];

    [IQKeyboardManager sharedManager].enable = NO;

}

- (void)viewWillDisappear:(BOOL)animated{

    [super viewWillDisappear:animated];

    [IQKeyboardManager sharedManager].enable = YES;

}

---

3.當我們導入IQKeyboardManager後默認會在鍵盤上出現一個工具條

如果不想使用可以設置[IQKeyboardManager sharedManager].enableAutoToolbar = NO;這樣工具條就會消失。

4.如果想要更改鍵盤上的return鍵

//聲明一個變量
@interface ViewController ()
{
    IQKeyboardReturnKeyHandler *returnKeyHandler;
}
@end

//在viewDidLoad中寫入
returnKeyHandler = [[IQKeyboardReturnKeyHandler alloc] initWithViewController:self];
//這樣鍵盤return會變成Next，只有當時最後一個時會變成return

---

5.點擊背景鍵盤下去

- (void)viewDidLoad {
    [super viewDidLoad];

    [IQKeyboardManager sharedManager].shouldResignOnTouchOutside = YES;
}

---

6.如果視圖有導航欄，上移View不想讓UINavgationBar消失

1.如果你使用的是storyboard or xib，只需將當前視圖視圖控制器中的UIView class變爲UIScrollView。

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

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

---

7.修改工具條上右側的Done按鈕

//設置爲文字
[IQKeyboardManager sharedManager].toolbarDoneBarButtonItemText = @"完成";

//設置爲圖片
[IQKeyboardManager sharedManager].toolbarDoneBarButtonItemImage = [UIImage imageNamed:@"imageName"];

---

8.修改工具條上字體的顏色

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

---

9.設置輸入框與工具條的間距，默認爲10.0f

[IQKeyboardManager sharedManager].keyboardDistanceFromTextField = 0.0f;

---

10防止IQKeyboardManager讓rootview上滑過度,默認是YES

[IQKeyboardManager sharedManager].preventShowingBottomBlankSpace = NO;
