如何从iPhone中的字符串评估中获取整数值？

Question

我有像这样@"0,0,0,0,0,0,1,2012-03-08,2012-03-17"的NSString。我想要用逗号分隔的值。我想要逗号之前的值，而忽略逗号。

我是iPhone新手，我知道如何用Java做，但没有在Objective-C中做怎么做。

Answer 1

NSString *string = @"0,0,0,0,0,0,1,2012-03-08,2012-03-17";

NSArray *componentArray = [string componentSeperatedByString:@","];

Answer 2

使用NSString的{​​{3}}方法。

NSString *str = @"0,0,0,0,0,0,1,2012-03-08,2012-03-17";
NSArray *components = [str componentsSeparatedByString:@","];

for (NSString *comp in components)
{
    NSLog(@"%@", comp);
}

Answer 3

for (NSString *s in [yourstring componentsSeparatedByString:@","])
{
    int thisval = [s intValue];
}
