解决了iOS7上position对象总是不为nil造成判断不准的问题
- (void)nikeNameTFDidChange {
NSString *toBeString = self.nickName.text;
// 当前输入法 - 这个判断可以去掉其实
NSString *inputLanguage = [[self.nickName textInputMode] primaryLanguage];
if([inputLanguage isEqualToString:@"zh-Hans"]){ //简体中文输入，包括简体拼音，健体五笔，简体手写
//获取高亮部分
UITextRange *selectedRange = [self.nickName markedTextRange];
UITextPosition *position = [self.nickName positionFromPosition:selectedRange.start offset:0];
// 没有高亮选择的字，则对已输入的文字进行字数统计和限制
// DL修改 添加判断条件 || !selectedRange
if (!position || !selectedRange){
//非高亮
[self processNickNameText:toBeString];
}
}else{
//中文输入法以外
[self processNickNameText:toBeString];
}
}
- (void)processNickNameText:(NSString *)toBeString {
if (toBeString.length > 11) {
self.nickName.text = [toBeString substringToIndex:11];
[MBProgressHUD showMessage:@"您最多只能输入11个字" toView:self.view hudConfig:nil];
}else if (toBeString.length == 11 && [self.nickName.text isEqualToString:_loginname]) {
self.nickName.text = [self.nickName.text stringByReplacingCharactersInRange:NSMakeRange(3, 4) withString:@"****"];
[MBProgressHUD showMessage:@"您的昵称为手机号，将加密展示~" toView:self.view hudConfig:nil];
}
}
