4 twitter 分享文档：
https://docs.fabric.io/apple/twitter/compose-tweets.html 分享参考：
- (void)showTwitterCompose{
TWTRComposer *composer = [[TWTRComposer alloc] init];
[composer setText:@"I am big big man"];
[composer setURL:[NSURL URLWithString:@"https//:www.baidu.com"]];
if (composer) {
NSLog(@"composer = %@",composer);
[composer showFromViewController:self completion:^(TWTRComposerResult result) {
if (result == TWTRComposerResultDone) {
NSLog(@"twitter share done");
}else if (result == TWTRComposerResultCancelled){
NSLog(@"twitter share cancell");
}
}];
}
}
- (void)showTwitterSessionShare{
// Objective-C
// Users must be logged-in to compose Tweets
TWTRSession *session = [Twitter sharedInstance].sessionStore.session;
// User generated image
UIImage *image = [UIImage imageNamed:@"XXXXX"];
// Create the card and composer
TWTRCardConfiguration *card = [TWTRCardConfiguration appCardConfigurationWithPromoImage:image iPhoneAppID:nil iPadAppID:nil googlePlayAppID:nil];
TWTRComposerViewController *composer = [[TWTRComposerViewController alloc] initWithUserID:session.userID cardConfiguration:card];
// Optionally set yourself as the delegate
composer.delegate = self;
// Show the view controller
[self presentViewController:composer animated:YES completion:nil];
}
5 问题：
在ios 9.2.1 上测试，如果用户没登录Twitter账号，点击Twitter分享会崩溃。 出现的错误日志如下：
```** Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘Application tried to present a nil modal view controller on target <ViewController: 0x14e43d60>.’ ** First throw call stack: (0x239ab91b 0x23146e17 0x28294ab1 0x28296d25 0x28296f91 0x2801ddb9 0x1928b5 0x906e5 0x9057b 0x27f5c755 0x27f5c6e1 0x27f446d3 0x27f5c005 0x27f5bc7f 0x27f5468f 0x27f25125 0x27f236d3 0x2396ddff 0x2396d9ed 0x2396bd5b 0x238bb229 0x238bb015 0x24eabac9 0x27f8d189 0x92def 0x23563873) libc++abi.dylib: terminating with uncaught exception of type NSException
暂时的解决方式：
1. 申请访问Account权限（ios 10，要添加到info.plist中）；
2. 访问Account的实现代码：
// ios 10 在info.plist添加访问权限 ACAccountStore *store = [[ACAccountStore alloc]init]; ACAccountType *twitterType = [store accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter]; [store requestAccessToAccountsWithType:twitterType options:nil completion:^(BOOL granted, NSError *error) { if (granted){ NSArray *array = [store accountsWithAccountType:twitterType]; NSLog(@”accounts = %@”,array); if (array.count > 0) {// 显示Twitter分享功能 [self showTwitterCompose]; }else{ // 提示用户添加账号信息 } }else{ NSLog(@”—-no—-“);
// 提示用户允许访问账号信息
}
}]; ```
