Xcode iOS: Convert int to NSString
提问by Giel
I'm trying to grab avalue from a UIPicker which is populated with round numbers, integers pulled from and NSMutableArray. I'm trying to convert the pulled values to an actual int.
我正在尝试从 UIPicker 中获取一个值，该 UIPicker 填充了整数、从 NSMutableArray 中提取的整数。我正在尝试将拉取的值转换为实际的整数。
I tried this in the .m:
我在 .m 中试过这个：
int pickednumber;
......
-(void) pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component{
NSString *numbers = [arrayNumbers objectAtIndex:[pickerView selectedRowInComponent:0]];
pickednumber = [NSString stringWithFormat:@"%d", numbers];
NSLog(@"Picked number %@ ", numbers);
}
I get the error in the pickednumber = line: Incompatible pointer to integer conversion assigning to 'int' from 'id'. What am i doing wrong?
我在 picknumber = 行中收到错误：Incompatible pointer to integer conversionassigning to 'int' from 'id'。我究竟做错了什么？

pickednumber = [numbers intValue];
NSLog(@"Picked number %d ", numbers); // not %@ ..%@ is for objects .. not int
