IQKeyboardManager基本使用

最近项目中使用到了IQKeyboardManager
把使用的一些方法做一下简单的介绍，干货都在下面，开撸

1 AppDelegate里倒入头文件即可使用，

 #import <IQKeyboardManager/IQKeyboardManager.h>

2.某个界面不使用IQKeyboardManager

- (void)viewWillAppear:(BOOL)animated{

[super viewWillAppear:animated];

[IQKeyboardManager sharedManager].enable = NO;
}

- (void)viewWillDisappear:(BOOL)animated{

[super viewWillDisappear:animated];

[IQKeyboardManager sharedManager].enable = YES;

}

3.工具条消失

[IQKeyboardManager sharedManager].enableAutoToolbar = NO;

4 return键改为next ，最后一个textfield变为 return

#import <IQKeyboardReturnKeyHandler.h>
／／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.点击空白处 键盘隐藏

    [IQKeyboardManager sharedManager].shouldResignOnTouchOutside = YES;

6 键盘弹起，视图上移 UINavgationBar消失

1使用 storyboard 或者 xib

只需将view的Class 换成 UIScrollView

这时候你会发现，What is the Fuck？ 视图全他妈乱了，莫慌莫慌，
只需要给scrollview中的某一个view拉入一条相对scrollview的约束：Center Horizontally in Container

2 代码需要覆盖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;
