前言：之前聽說過微信支付有很多坑，其實沒有想象的那么坑，整體感覺很容易上手，按照它的流程來不會有錯！PS:官方的流程看的TMD煩，好啦，廢話有點多，進(jìn)入開發(fā)。（ps:每個微信的版本一直都在更新，這是2015/12/1給你們做的標(biāo)記下QQ:1055167383,歡迎隨便騷擾，女士優(yōu)先！大神也優(yōu)先！咦…）
1.? ? 導(dǎo)入微信支付庫
微信開放平臺新增了微信模塊用戶統(tǒng)計功能，便于開發(fā)者統(tǒng)計微信功能模塊的用戶使用和活躍情況。開發(fā)者需要在工程中鏈接上:SystemConfiguration.framework,libz.dylib,libsqlite3.0.dylib。
最重要的時這個庫：libc++.dylib《ps:官方的文檔沒說，艸！》
2.在AppDelegate中導(dǎo)入：
（1）#import "WXApi.h"
#import "WXApiObject.h"
遵守WXApiDelegate
在這個方法里注冊
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[WXApi registerApp:WXAppId withDescription:@"yishuPayDes"];
}
（2）跳轉(zhuǎn)處理
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation
{
NSLog(@"跳轉(zhuǎn)到URL schema中配置的地址-->%@",url);//跳轉(zhuǎn)到URL schema中配置的地址
if ([UMSocialSnsService handleOpenURL:url]) {
return??[UMSocialSnsService handleOpenURL:url];
}else{
return [WXApi handleOpenURL:url delegate:self];
}
}
（3）回調(diào)方法
-(void) onResp:(BaseResp*)resp
{
NSString *strMsg = [NSString stringWithFormat:@"errcode:%d", resp.errCode];
NSString *strTitle;
if([resp isKindOfClass:[SendMessageToWXResp class]])
{
strTitle = [NSString stringWithFormat:@"發(fā)送媒體消息結(jié)果"];
}
if([resp isKindOfClass:[PayResp class]]){
//支付返回結(jié)果，實際支付結(jié)果需要去微信服務(wù)器端查詢
strTitle = [NSString stringWithFormat:@"支付結(jié)果"];
switch (resp.errCode) {
case WXSuccess:{
strMsg = @"支付結(jié)果：成功！";
NSLog(@"支付成功－PaySuccess，retcode = %d", resp.errCode);
NSNotification *notification = [NSNotification notificationWithName:ORDER_PAY_NOTIFICATION object:@"success"];
[[NSNotificationCenter defaultCenter] postNotification:notification];
break;
}
default:{
strMsg = [NSString stringWithFormat:@"支付結(jié)果：失敗！retcode = %d, retstr = %@", resp.errCode,resp.errStr];
NSLog(@"錯誤，retcode = %d, retstr = %@", resp.errCode,resp.errStr);
NSNotification *notification = [NSNotification notificationWithName:ORDER_PAY_NOTIFICATION object:@"fail"];
[[NSNotificationCenter defaultCenter] postNotification:notification];
break;
}
}
}
//????UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
//????[alert show];
}
（4）.接下來在需要支付的界面做這些事：
//監(jiān)聽通知
- (void)viewWillAppear:(BOOL)animated{
[self requestDownloadData];
if([WXApi isWXAppInstalled]) // 判斷 用戶是否安裝微信
{
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(getOrderPayResult:) name:ORDER_PAY_NOTIFICATION object:nil];//監(jiān)聽一個通知
}
[super viewWillAppear:animated];
}
/*ORDER_PAY_NOTIFICATION*/這個寫個宏，全局里寫，怎么寫？建.h文件！
//移除通知
- (void)viewWillDisappear:(BOOL)animated{
[[NSNotificationCenter defaultCenter]removeObserver:self];
}
開始支付-----→終于等到你，還好沒放棄！
1.????預(yù)備工作，(1)我這里封裝了下載類AF(自己感覺比較方便，親們自己寫下載就好了，因為我們公司的網(wǎng)絡(luò)數(shù)據(jù)就那么幾種)主要用于請求后臺服務(wù)器已經(jīng)做好的數(shù)據(jù)，請求下來的參數(shù)給微信，用于支付！(2)獲取每臺設(shè)備的IP地址,(3)HUD是啥，大家都用過，不說了（ps:HUD特效，自己定義看看那種效果好!）(4)后臺做了什么：http://wxpay.weixin.qq.com/pub_v2/app/app_pay.php這個地址給后臺參考下，需要的參數(shù)都在上面移動端不需要寫，如果你要寫，我不攔你…哈哈，當(dāng)練手吧!
