我在Objective C中遇到崩溃未捕获异常'NSRangeException'，原因：'*** __boundsFail：索引3超出范围[0 .. 2]'
这一行的 crashlytics 问题“label.text = [_addressTypeArray objectAtIndex:row];”
如果可能，请参阅下面的代码和帮助
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 1;
}
**- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
if (isStateButtonClicked == YES) {
return _stateTypeArray.count;
} else
return _addressTypeArray.count;
}

}
else {
