iphone - 将 NSString 转换为 Int

Question

我尝试将NSString转换为int，结果dpPoint:0，我想要dpPoint:2

dpPointStr = [NSString stringWithFormat:@"%@",[verifyRow valueForKey:@"default_point"]];
NSLog(@"dpPointStr:%@",dpPointStr); //Result dpPointStr:2

int dpPoint = [dpPointStr intValue];
NSLog(@"dpPoint:%i",dpPoint); //Result dpPoint:0

Answer 1

在您的情况下，如果值位于字符串的开头/结尾，您可以尝试以下操作:

int val = [[dpPointStr stringByTrimmingCharactersInSet:[[NSCharacterSet decimalDigitCharacterSet] invertedSet]] intValue];
