iOS 判断页面中的该填项是否填完整,改变按钮状态的方法

//判断是否有值,只要有NO，就为灰色，如果都为yes，那就直到最后一个都为yes时，即为yes+ (void)setButtonStatusBytextFeilds:(NSArray *)textFeildArr button:(UIButton *)button{ for (UITextField *textF in textFeildArr) { if (textF.text.length <= 0) {  [button setBackgroundColor:kLineColor];  button.enabled = NO;  return; }else{  if ([(UITextField *)textFeildArr[textFeildArr.count - 1] text] > 0) {  [button setBackgroundColor:kGreenColor];  button.enabled = YES;  } } }}

//给每个textFeild 添加监听self.textFArr = @[_passordF,_surePasswordF]; for (UITextField *textF in _textFArr) {  [textF addTarget:self action:@selector(setBtnStatus) forControlEvents:(UIControlEventEditingChanged)]; }

//调取判断方法- (void)setBtnStatus{ [ShowTool setButtonStatusBytextFeilds:_textFArr button:_registerBtn];}
