iOS判断手机上是否安装微信或qq等应用

1。基于ShareSDK

#import <ShareSDK/ShareSDK.h>
#import "WXApi.h"
#import <TencentOpenAPI/QQApi.h>

if ([WXApi isWXAppInstalled]) {
//判断是否有微信
}

if ([QQApi isQQInstalled]) {
//判断是否有qq
}

2.基于系统

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"Sinaweibo://"]])
{

//新浪微博

}

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"Whatapp://"]])
{

//微信

}

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"weixin://"]])
{

//微信

}

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"Facebook://"]])
{

//facebook

}

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"Twitter://"]])
{

//推特

}
