IOS 整合第三方登入，ios整合第三方

     我使用的是友盟上整合的第三方登入功能，一共使用了三個應用的登入授權，QQ、、新浪微博。由於第三方登入授權成功後，需要跳轉到一個新的介面，所以這裡需要在項目裡設定第三方登入的SSO授權。就是必須安裝了相關的手機用戶端後，才能使用第三方登入，在使用第三方登入時，我們需要先判斷一下使用者手機上是否已經安裝了對應的應用。

一、整合SSO授權

    這裡整合SSO授權的方法我就不詳細講解了，因為還涉及到註冊第三方平台帳號這些瑣屑的事。下面我給一個友盟上整合SSO授權的地址，文檔說明都是很詳細的

二、對應控制項的布局代碼

 1   NSArray *imageArray=[[NSArray alloc]initWithObjects:@"btn_3_weixin",@"btn_3_qq",@"btn_3_weibo", nil]; 2                     UIImageView  *shareButton; 3                     CGFloat firstButtonWdith=0; 4                     CGFloat  axisY=functionButton.frame.origin.y+functionButton.frame.size.height+40; 5                     CGFloat thisWidht=DEVICE_Width-76; 6                      7                     UILabel *thisShareLabel; 8                     for (int sh=0;sh<3;sh++) { 9                         shareButton=[[UIImageView alloc]init];10                         if (sh==0) {11                             thisShareLabel=[[UILabel alloc]initWithFrame:CGRectMake(38, axisY+7, thisWidht*0.25, 1)];12                             thisShareLabel.backgroundColor=[UIColor whiteColor];13                             shareButton.frame = CGRectMake(  thisShareLabel.frame.origin.x+thisShareLabel.frame.size.width*0.18 , thisShareLabel.frame.origin.y+20,thisShareLabel.frame.size.width*0.64 , thisShareLabel.frame.size.width*0.64);14                             15                             firstButtonWdith=shareButton.frame.size.width;16                             17                         }18                         else if(sh==1)19                         {20                             thisShareLabel=[[UILabel alloc]initWithFrame:CGRectMake(thisShareLabel.frame.size.width+thisShareLabel.frame.origin.x, axisY, thisWidht*0.5, 14)];21                             thisShareLabel.text=@"第三方賬戶登入";22                             23                             shareButton.frame = CGRectMake(  thisShareLabel.frame.origin.x+thisShareLabel.frame.size.width/2-(firstButtonWdith/2) , thisShareLabel.frame.origin.y+26,firstButtonWdith, firstButtonWdith);24                            25                         }26                         else27                         {28                             thisShareLabel=[[UILabel alloc]initWithFrame:CGRectMake(thisShareLabel.frame.size.width+thisShareLabel.frame.origin.x, axisY+7, thisWidht*0.25, 1)];29                             thisShareLabel.backgroundColor=[UIColor whiteColor];30                             31                             shareButton.frame = CGRectMake(  thisShareLabel.frame.origin.x+thisShareLabel.frame.size.width*0.18 , thisShareLabel.frame.origin.y+20,thisShareLabel.frame.size.width*0.64 , thisShareLabel.frame.size.width*0.64);32                         }33                         thisShareLabel.font=[UIFont systemFontOfSize:14];34                         thisShareLabel.textAlignment=NSTextAlignmentCenter;35                         thisShareLabel.textColor=[UIColor whiteColor];36                         [self addSubview:thisShareLabel];37                       38                         [shareButton setImage:[UIImage imageNamed:[imageArray objectAtIndex:sh]]];39                         shareButton.userInteractionEnabled=YES;40                         UIGestureRecognizer *thirdSDKLoginUIGestureRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(thirdSDKLogin:)];41                         [shareButton addGestureRecognizer:thirdSDKLoginUIGestureRecognizer];42                          shareButton.tag=123456+sh;43                         [self addSubview:shareButton];44                         if (sh==2) {45                             self.backScrollView .scrollEnabled=YES;46                             if (DEVICE_Height<500) {47                                 [self.backScrollView  setContentSize:CGSizeMake(DEVICE_Width, self.backScrollView.contentSize.height+50)];48                             }49                         }50                       51                         52                     }

 

 

上面當然只是登入介面中第三方登入塊的部分代碼，是相對於上一個控制項 functionButton來布局的，下面是布局效果

三、第三方登入實現代碼

這裡首先需要實現功能的ViewController中引入對應的庫

#import "UMSocial.h"

#import "WXApi.h" 

#import <TencentOpenApi/QQApiInterface.h> 

#import "WeiboSDK.h"

下面的方法就是就是上面代碼中UIImageView  *shareButton綁定的手勢，這裡為什麼要使用UIImageView,

因為我代碼布局中 shareButton的寬度和高度沒有固定，是根據螢幕的寬度來計算的，如果使用UIButton就會出現

貼的圖片的大小不會隨著動態計算出的高寬而縮放，如果寫代碼放大縮小又會出現模糊狀態。
