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

在becomeKeyWindow 内加上 异步。
