将字符串转换为Float

Question

我正在尝试将字符串解析为数组，在索引1处获取数组的一部分并将该字符串转换为float。我在这里有我的代码，但是我收到了错误“Intializing'flora'，表达了不兼容的类型'NSString * _strong'。帮助！

NSString *csv = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://download.finance.yahoo.com/d/quotes.csv?s=AAPL&f=sl1d1t1c1ohgv&e=.csv"]];

NSArray *array = [csv componentsSeparatedByString: @","];

NSString *price = [array objectAtIndex:1];

[price floatValue];

float currentPrice = price;

Answer 1

尝试

float currentPrice = [price floatValue];

Answer 2

试试这个

float currentPrice = [price floatValue];

Answer 3

your_float = [your_string floatValue];

试试这个：

NSLog(@"float value is: %f", your_float);
