我有一种情况,即从应用程序中的CSV文件读取的数据必须转换为整数,稍后必须绘制。目前它不能识别何时将数据保存为将NSArray组件转换为整数或十进制数
int i=[[rows objectAtIndex:0] componentsSeparatedByString:@","];
这是实施的代码。
-(void)connection :(NSURLConnection *) connection didReceiveData:(NSData *)data{
[self serverConnect];
response = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
//NSLog(response);
NSString *stripped1 = [response stringByReplacingOccurrencesOfString:@"\r" withString:@""];
NSArray *rows = [stripped1 componentsSeparatedByString:@"\n"];
NSArray *components;
for (int i=0;i<[rows count]; i++) {
if(i == 0 || [[rows objectAtIndex:i] isEqualToString:@""]){
continue;
}
components = [[rows objectAtIndex:i] componentsSeparatedByString:@","];
NSLog(@"data1:%@ data2:%@ data3:%@", [components objectAtIndex:0] ,[components objectAtIndex:1],[components objectAtIndex:2]);
}
data1
,data2
和data3
应该是整数。
非常感谢。
