问题一:
总共三个UITextField, originalPwd/inputedPwd 键盘显示next,confirmedPwd键盘显示Go:
@property (weak, nonatomic) IBOutlet UITextField *originalPwd; @property (weak, nonatomic) IBOutlet UITextField *inputedPwd; @property (weak, nonatomic) IBOutlet UITextField *confirmedPwd;
但是键盘上的next和go根本没有反应,在UITextFieldDelegate方法 textFieldShouldReturn加断点不进入。
解决:经检查,翻了一个低级错误,没有设置UITextField的delegate。。。。。。
问题二:
第一次点击UITextField时keyboard延迟大概3s,难以接受。
解决:在viewDidLoad中加入以下打码
UITextField *field = [UITextField new]; [[[[UIApplication sharedApplication] windows] lastObject] addSubview:field]; [field becomeFirstResponder]; [field resignFirstResponder]; [field removeFromSuperview];
ps:虽然keyboard不延迟了,但是整个View第一次加载延迟了, 改成如下:
// resolve keyboard delay dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 0.0), dispatch_get_main_queue(), ^{ UITextField *field = [UITextField new]; [[[[UIApplication sharedApplication] windows] lastObject] addSubview:field]; [field becomeFirstResponder]; [field resignFirstResponder]; [field removeFromSuperview]; });
