如何使用stringWithFormat方法追加字符串變量Objective-C

Question

我想使用stringWithFormat.I將字符串追加到單個變量中。我在使用stringByAppendingString時知道它。請幫我使用stringWithFormat附加下面的代碼。

NSString* curl = @"https://invoices?ticket="; 
curl = [curl stringByAppendingString:self.ticket]; 
curl = [curl stringByAppendingString:@"&apikey=bfc9c6ddeea9d75345cd"]; 
curl = [curl stringByReplacingOccurrencesOfString:@"\n" withString:@""]; 

謝謝， Madan Mohan。

可以構建使用-stringWithFormat:方法您curl字符串：

NSString *apiKey = @"bfc9c6ddeea9d75345cd"; 
NSString* curl = [NSString stringWithFormat:@"https://invoices?ticket=%@&apikey=%@", self.ticket, apiKey];
