如何从iPhone中的nsstring评估中获取整数值？

Question

我有这样的NSString @"0,0,0,0,0,0,1,2012-03-08,2012-03-17"。我需要用逗号分隔的值。我需要逗号前的值并忽略逗号。

我是新来的iPhone，我知道如何在Java中做，但没有得到如何做在Objective-C。

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componentsSeparatedByString: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]; 
}
