1,pickerView 永远是第一响应
之前项目中要加入pickerView来选择年份和月份,自己封装的时候本来想在pickerView上加响应视图,无果,pickerView永远都是第一响应。
2,应用内跳转
//iCloud设置界面
NSURL *url = [NSURL URLWithString:@"prefs:root=CASTLE"]; if ([[UIApplication sharedApplication] canOpenURL:url] { [[UIApplication sharedApplication] openURL:url]; }

3,收起键盘的方法
以前做这个需求的时候是,让指定的textField取消第一响应
[self.textField resignFirstResponder];
后来的做法是可以直接让视图变成不可编辑状态
[self.view endEditing:YES];
