私はUIPickerViewを持っています。私は、行を選択すると、この処理が行われます。SIGABRTの致命的なエラー
- (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
switch ([defaults integerForKey:@"randomIndex"]) {
case 1:

case 0:
[defaults setInteger:row forKey:@"randomIndex"];
[defaults synchronize];
[colourPicker reloadAllComponents];

、私は、get最初に戻って、その後UIPickerビュー上に行くと二行に1列を変更したときa SIGABRT致命的なエラーです。ログは次のとおりです。
