转换NSString到Int类型

Question

转换NSString到Int类型，得到dpPoint:0。而我需要的结果是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

如果值在字符串的开始或结尾处，可以这样试试：

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