ibus输入法故障

sudo yum remove ibus －－会将所有的输入法删除
安装ibus,ibus-table
sudo yum install ibus ibus-table –这样只会安装ibus的输入框架
sudo yum install ibus-table-wubi
yum install “@Chinese Support”

解决 CentOS 6.x 升级 Python2.7 后 Ibus 输入法无法使用问题
/usr/libexec/ibus-ui-gtk
/usr/ bin/ibus-setup
/usr/libexec/ibus-engine-table

将以上三个文件中的 “exec python” 修改为 “exec python26”

Qt与Object-C混合编程

1.添加proxy_ios.h文件，内容如下：
#ifndef PROXY_IOS_H
#define PROXY_IOS_H

QString systemProxy();

#endif // PROXY_IOS_H
2.添加proxy_ios.mm文件，内容如下：

#import
#import
#include

QString systemProxy(){
NSDictionary *proxySettings = NSMakeCollectable([(NSDictionary *)CFNetworkCopySystemProxySettings() autorelease]);
NSArray *proxies = NSMakeCollectable([(NSArray *)CFNetworkCopyProxiesForURL((CFURLRef)[NSURL URLWithString:@"http://www.baidu.com"], (CFDictionaryRef)proxySettings) autorelease]);
NSDictionary *settings = [proxies objectAtIndex:0];

QString host = QString::fromNSString([NSString stringWithFormat:@"%@", [settings objectForKey:(NSString *)kCFProxyHostNameKey]]);
QString port = QString::fromNSString([NSString stringWithFormat:@"%@", [settings objectForKey:(NSString *)kCFProxyPortNumberKey]]);
// QString type = QString::fromNSString([NSString stringWithFormat:@"%@", [settings objectForKey:(NSString *)kCFProxyTypeKey]]);
return host+":"+port;
}
3.在.pro工程文件中添加：
ios {
QMAKE_LFLAGS += -framework OpenGLES
QMAKE_LFLAGS += -framework GLKit
QMAKE_LFLAGS += -framework QuartzCore
QMAKE_LFLAGS += -framework CoreVideo
QMAKE_LFLAGS += -framework CoreAudio
QMAKE_LFLAGS += -framework CoreImage
QMAKE_LFLAGS += -framework CoreMedia
QMAKE_LFLAGS += -framework AVFoundation
QMAKE_LFLAGS += -framework AudioToolbox
QMAKE_LFLAGS += -framework CoreGraphics
QMAKE_LFLAGS += -framework UIKit
QMAKE_LFLAGS += -framework CFNetwork
}
4.使用Qt添加proxy_ios.h和proxy_ios.mm文件。
5.在main.cpp文件中调用如下：
#include "proxy_ios.h"
void setDefaultProxy(){
QString hostport = systemProxy();
qDebug() <<"had find proxy address:" << hostport; if(!hostport.isEmpty()){ QStringList ip_port = hostport.split(':'); if(ip_port.length() != 2){ return; } QString host = ip_port.at(0); QString port = ip_port.at(1); if(host.contains("null") || port.contains("null")){ return; } bool ok = false; int iport = port.toInt(&ok); if(!ok || iport <= 0){ return; } QNetworkProxy proxy; proxy.setType(QNetworkProxy::HttpProxy);//设置类型 proxy.setHostName(host);//设置代理服务器地址 proxy.setPort(iport);//设置端口 QNetworkProxy::setApplicationProxy(proxy); qDebug() <<"+++had set proxy address:" << hostport; } }
6.编译即可。
