Question

这太荒谬了，我看不出我的代码有什么问题。我希望有人能帮助我对的。问题是当resignfirstresponder触发时，似乎出现了另一个UIKeyboard，请注意完成按钮更改为键盘上的普通返回按钮。

我的testViewController.m文件

#import <QuartzCore/QuartzCore.h>
#import <UIKit/UIKit.h>
#import "testViewController.h"
#define kOFFSET_FOR_KEYBOARD 216.0
@interface testViewController ()
{
    float increase;
    int increases;
    UITextView *txt;
    UIView *vw;
    UIView *tvw;
    UITableView *tbl;
    UIButton *b;
}
@end

@implementation testViewController

- (void)viewDidLoad {
    vw =[[UITextView alloc]initWithFrame:CGRectMake(0, self.view.frame.size.height-34, 320, 1000)];
    vw.backgroundColor =[UIColor blackColor];
    tbl =[[UITableView alloc]initWithFrame:CGRectMake(0, 0, 320, self.view.frame.size.height-34)];
    txt =[UITextView new];
    txt.frame=CGRectMake(4, 4, 255, 25);
    [txt setScrollEnabled:NO];
    txt.contentInset = UIEdgeInsetsMake(4, 4, 0, 0);
    [tbl setDelegate:self];
    [tbl setDataSource:self];
    [txt setDelegate:self];
    [txt setReturnKeyType:UIReturnKeyDone];
    [self.view addSubview:tbl];
    [[txt layer] setCornerRadius:2.0f];
    [vw addSubview:txt];
    [self.view addSubview:vw];
    increases = 0;
    increase =23;
    txt.text =@"Give me text...";

你似乎有一个UITextView，你的意思是在初始化vw时有一个UIView，这导致你在UITextView中有一个UITextView。

为什么我的UIKeyboard不会在resignfirstresponder上消失
