Ios 如何使用函数最小化重复代码？

（无效）重复 { NSNumberFormatter*tFormatter=[[NSNumberFormatter alloc]init]

[tFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]

[t格式设置MaximumFractionDigits:0]

NSString*formattedt=[tTaxFormatter stringFromNumber:[NSNumber numberWithFloat:？？]]

self.tLabel.text=[NSString stringWithFormat:@“%@”，formattedt]； }

---

只创建一个

NSNumberFormatter

对象，并在所有三个位置使用它。这将缩短您的代码，使其看起来更干净。

而且效率更高。谢谢，删除了3000行代码。我认为1个对象的NSNumberFormatter是1

float qwer4 = 0;

NSNumberFormatter *eFormatter = [[NSNumberFormatter alloc] init];

[eFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];

[eFormatter setMaximumFractionDigits:0];

NSString *formattede = [eFormatter stringFromNumber:[NSNumber numberWithFloat:qwer4]];

self.eLabel.text = [NSString stringWithFormat:@"%@",formattede];//





float qwer6 = qwer4*6/100; 

NSNumberFormatter *pFormatter = [[NSNumberFormatter alloc] init];

[pFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];

[pFormatter setMaximumFractionDigits:0];

NSString *formattedpTax = [pFormatter stringFromNumber:[NSNumber numberWithFloat:qwer6]];

self.pLabel.text = [NSString stringWithFormat:@"%@",formattedp];




NSNumberFormatter *tFormatter = [[NSNumberFormatter alloc] init];

[tFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];

[tFormatter setMaximumFractionDigits:0];

NSString *formattedtTax = [tTaxFormatter stringFromNumber:[NSNumber numberWithFloat:qwer4 + qwer6]];

self.tLabel.text = [NSString stringWithFormat:@"%@",formattedt];
