直接調用下方代碼中的方法判斷即可
#pragma mark 判斷字符串是否為浮點數
- (BOOL)isPureFloat:(NSString*)string{
NSScanner* scan = [NSScanner scannerWithString:string];
float val;
return[scan scanFloat:&val] && [scan isAtEnd];
}
#pragma mark 判斷是否為整形
- (BOOL)isPureInt:(NSString*)string{
NSScanner* scan = [NSScanner scannerWithString:string];
int val;
return [scan scanInt:&val] && [scan isAtEnd];
}
