https://*.com/questions/24050012/error-library-not-found-for

I had a similar "library not found" issue. However it was because I accidentally was using the .xcodeproj file instead of the .xcworkspace file.

推送问题

Cannot create a iOS App Development provisioning profile for "com.haoning.demo123121".
Your development team, "leaf french", does not support the Push Notifications capability.
把
NIMDev.entitlements
的
<dict>
<key>aps-environment</key>
<string>development</string>
</dict>
改成
<dict>
</dict>

Xcode 运行项目时候选择模拟器位置处显示"My Mac" 的处理

1、先关闭Xcode，找到该工程项目目录，找到该项目的***.xcodeproj 文件，然后右键点击选择“显示包内容”；
2、包内容中显示以下三项：project.pbxproj .project.xcworkspace .xcuserdata 接着选择“xcuserdata”这个文件夹，将其整个移到废纸篓，重新打开你的项目，则可使用Simulator；
3、如果上诉方法没有用, 那么找到target->built settings->Architectures->Base SDK.这里改成你需要的iOS版本即可。

#pragma mark - 消息发送时间截获
- (void)sendMessage:(NIMMessage *)message didCompleteWithError:(NSError *)error
{
    printf("sendMessage---->hello hit me!!\n");
   // NSString *message_temp = @"aaa";
    //message =  mytext.text;

//  printf("------->sendMessage--begin----->\n");
    NSLog(@"---NTESSessionViewController-->sendMessage----->>>>>>%@",message);
//  printf("------->sendMessage--end----->\n");

1。新建target framework & Library ,选Cocoa Touch Static Library 文字为SocketRocket
2。SRWebSocket.h 和.m覆盖过来
3.编译完SocketRocket的target
4.切换到im的target，爸libsocketrockt.a作为build Phrase的link binary with library引入进来
，还要引入foundtion.framework Security.framework CFNetwork.framework
3.ViewController引入
#import "SRWebSocket.h"
@interface ViewController () <SRWebSocketDelegate>

@end
@implementation ViewController {
    SRWebSocket *_webSocket;
    NSMutableArray *_messages;
}

报错引入各种接口

- (void)viewDidLoad {
    [super viewDidLoad];
    printf("haha begin--> \n");
    _webSocket = [[SRWebSocket alloc] initWithURLRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"ws://localhost:3001"]]];

    _webSocket.delegate = self;
    [_webSocket open];

    [NSThread sleepForTimeInterval:0.1f];
    printf("haha   open--> \n");
    NSString *message = @"aaa";
    [_webSocket send:message];



    [_webSocket close];
    printf("haha   close--> \n");
    printf("haha   end--> \n");
    // Do any additional setup after loading the view, typically from a nib.
}


4.
Installing (iOS)
----------------
There's a few options. Choose one, or just figure it out

- You can copy all the files in the SocketRocket group into your app.
- Include SocketRocket as a subproject and use libSocketRocket

  If you do this, you must add -ObjC to your "other linker flags" option

- For OS X you will have to repackage make a .framework target.  I will take
  contributions. Message me if you are interested.


Depending on how you configure your project you may need to ``#import`` either
``<SocketRocket/SRWebSocket.h>`` or ``"SRWebSocket.h"``

Framework Dependencies
``````````````````````
Your .app must be linked against the following frameworks/dylibs

- libicucore.dylib
- CFNetwork.framework
- Security.framework
- Foundation.framework

    var index = clients.push(connection) - 1;
