IOS判断某参数是否为int或者float

- (BOOL)isPureFloat:(NSString *)string

{

    NSScanner* scan = [NSScanner scannerWithString:string]; 

    float val; 

    return [scan scanFloat:&val] && [scan isAtEnd];

}

 

- (BOOL)isPureInt:(NSString *)string

{

    NSScanner* scan = [NSScanner scannerWithString:string]; 

    int val; 

    return [scan scanInt:&val] && [scan isAtEnd];

}
