arrayWithObjects: Objects should be NSStrings
提问by Flocked
I used this code to file the rows in my UIPickerView:
我使用此代码在 UIPickerView 中归档行：
self.component1Data = [NSArray arrayWithObjects: @"Sample", @"Sample1", @"...", nil];
How can I get a NSString instead of the "sample"? I tried it with "%@" but it doesn't work:
如何获得 NSString 而不是“样本”？我用 "%@" 试过了，但它不起作用：
self.component1Data = [NSArray arrayWithObjects: @"%@",string, @"%@",string2, @"...", nil];
回答by bbum
self.component1Data = [NSArray arrayWithObjects: string, string2, nil];
Assuming string and string2 are of type NSString *.
假设 string 和 string2 的类型为NSString *。
