iOS Window

问题：
使用了YYText 后会存在输入框显示不出 copy，paste等 menu。

代码接口逻辑：
在VC添加一个 自定义alertView。alertView是添加在自定义window上面点。

核心代码如下

#import "AlertViewController.h"
#import <YYText.h>

@interface AlertViewController ()

@property (nonatomic, strong) UIWindow *window;
@property (nonatomic, copy) void (^showCompletionBlock)(void);
@property (nonatomic, strong) YYTextView *View11;



@end

@implementation AlertViewController

- (void)viewDidLoad {
    [super viewDidLoad];
 
    self.View11 = [[YYTextView alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
    [self.view addSubview:self.View11];
    self.View11.backgroundColor = UIColor.redColor;
    
    
    UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(100, 210, 50, 50)];
    btn.backgroundColor = [UIColor grayColor];
    [btn addTarget:self action:@selector(clickBtn) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn];
    
    
    UITextView *bt22n = [[UITextView alloc] initWithFrame:CGRectMake(300, 210, 100, 0100)];
    bt22n.backgroundColor = [UIColor blueColor];
     [self.view addSubview:bt22n];
    
}

- (void)clickBtn
{
    [self dismissInWindowAnimateCompletion:nil];
}

- (UIWindow *)window
{
    if (!_window) {
        _window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
        _window.windowLevel = UIWindowLevelAlert;
        _window.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
        _window.opaque = NO;
    }
    return _window;
}

- (void)showAnimated:(NSInteger)level completion:(void (^)(void))completion
{
     self.showCompletionBlock = completion;
    
    self.window.windowLevel = level;
    
    if (level == 1000) {
        self.window.backgroundColor = UIColor.yellowColor;
        self.window.frame = CGRectMake(100, 100, 100, 100);
    }
    
    [self.window setRootViewController:self];
    [self.window makeKeyAndVisible];
    // 1.也可以直接使用window.hidden 这样就可以不使用 makeKeyAndVisible。
    // 2， 如果视图添加了 UITextField 或者 UITextView，当成为第一响应者的时候，系统会将 UITextField 或者 UITextView 所在的window 设置为keyWindow。
    // 3.添加了YYText（其他的第三方也存在可能性）后，如果存在 YYTextEffectWindow 那么该第二点将被打破。不会将 UITextField 或者 UITextView 所在的window 设置为keyWindow。
//    self.window.hidden = NO;
}

- (void)dismissInWindowAnimateCompletion:(void (^)(void))completion
{
    [UIView animateWithDuration:0.3 animations:^{
        self.view.alpha = 0.0;
    } completion:^(BOOL finished) {
        [self removeWindow];
        dispatch_async(dispatch_get_main_queue(), ^{
            self.view.alpha = 1.0;
            if (completion) {
                completion();
            }
        });
    }];
}

- (void)removeWindow
{
    self.window.rootViewController = nil;
    self.window = nil;
    
//    if (![[UIApplication sharedApplication].windows.firstObject isKindOfClass:[self class]]) {
//        [[UIApplication sharedApplication].windows.firstObject makeKeyAndVisible];
//    }
}

添加了YYText结果如下：

可以看出keyWindow 会变成 YYTextEffectWindow，

不添加 YYText 结果如下：

- (void)viewDidLoad {
    [super viewDidLoad];
 
//    self.View11 = [[YYTextView alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
//    [self.view addSubview:self.View11];
//    self.View11.backgroundColor = UIColor.redColor;
    
    
    UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(100, 210, 50, 50)];
    btn.backgroundColor = [UIColor grayColor];
    [btn addTarget:self action:@selector(clickBtn) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn];
    
    
    UITextView *bt22n = [[UITextView alloc] initWithFrame:CGRectMake(300, 210, 100, 0100)];
    bt22n.backgroundColor = [UIColor blueColor];
     [self.view addSubview:bt22n];
    
}

解决思路：

1. self.window = nil; 之后使用
   // if (![[UIApplication sharedApplication].windows.firstObject isKindOfClass:[self class]]) {
   // [[UIApplication sharedApplication].windows.firstObject makeKeyAndVisible];
   // }
   将keyWindo修改

2. 修改库

在becomeKeyWindow 内加上 异步。
