如果您能帮助我解决问题，我将不胜感激，那么您
提前致谢 ！
我的问题1
然后，如果我不知道我是否能够更改UIativity
我还有其他错误。 。
我的错误是：“ AcceptView”没有可见的@interface声明选择器presentViewController:animated:completion:
我的问题2
我不知道如何更改连接按钮下方的代码
我想使用此代码连接按钮
该做的？
// partager button
self.buttonshera = [[UIButton alloc] init];
[self.buttonshera setBackgroundImage:[UIImage imageNamed:@"buttonorange.png"] forState:UIControlStateNormal];
[self.buttonshera setAlpha:0.9];
[self.buttonshera.titleLabel setTextColor:[UIColor whiteColor]];
[self.buttonshera setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[self.buttonshera.titleLabel setFont:[UIFont systemFontOfSize:11]];
[self.buttonshera setTitle:[NSLocalizedString(@"buttonshera", nil) uppercaseString] forState:UIControlStateNormal];
[self.buttonshera setFrame:CGRectMake(global.xmargin, ypositionstart + 60, global.bodywidth, 32)];
[self addSubview:self.buttonshera];
[buttonshera addTarget:self
action:@selector(didSelectShare)
forControlEvents:UIControlEventTouchUpInside];
我想连接这个

NSMutableArray *activityItems = [NSMutableArray array];
NSString *htmlBody = @"<html><body><h1>Customized body</h1></body></html>";
// For Mail
[activityItems addObject:[WHMailActivityItem mailActivityItemWithSelectionHandler:^(MFMailComposeViewController *mailController) {
[mailController setSubject:@"Hey it's a subject!"];
[mailController setMessageBody:htmlBody isHTML:YES];
[mailController addAttachmentData:[htmlBody dataUsingEncoding:NSUTF8StringEncoding]
mimeType:@"text/html"
fileName:@"Awesome Attachment.html"];
mailController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
}]];
// For texting
[activityItems addObject:[WHTextActivityItem textActivityItemWithSelectionHandler:^(MFMessageComposeViewController *messageController) {
[messageController setBody:@"My super awesome message for texting only!"];
messageController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
}]];
// For everything else

最佳答案
presentViewController:animated:completion:是仅用于ViewControllers的方法，您正在将它用于不是控制器的ScrollView（AcceptView）类，因此会出现错误，如果要使用AcceptView，则必须将其作为CustomClass加载到ScrollView中无法显示或取消。
关于ios - 'AcceptView'的可见@interface没有声明选择器'presentViewController:animated:completion:'，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/24952803/
