取消某个页面的侧滑返回页面
直接自定义设置返回按钮就好了，不要用默认的返回按钮。
//btn_back
self.navigationItem.leftBarButtonItem= [[UIBarButtonItemalloc]initWithImage:[UIImageimageNamed:@"btn_back"]style:UIBarButtonItemStylePlaintarget:selfaction:@selector(showMessage)];
//返回提示信息
-(void)showMessage{
[UIAlertViewalertWithCallBackBlock:^(NSIntegerbuttonIndex) {
if(buttonIndex ==1) {
[self.navigationControllerpopViewControllerAnimated:YES];
}
}title:@"提示"message:@"确定要放弃本次发布吗"cancelButtonName:@"取消"otherButtonTitles:@"确定",nil];
}
