Implicit Conversion from NSInteger to NSString not allowed in ARC.. what workaround should be used to deal with Integers
提问by Pang Zi Yang
This is my code in my viewcontroller.m file
这是我在 viewcontroller.m 文件中的代码
- (void)viewDidLoad{
[super viewDidLoad];
[self.abilitygeneration setText:((TestAbility *)[self.testabilities objectAtIndex:0]).abilitygeneration]; }
It gives me an error implicit conversion of NSInteger aka int to NSString is disallowed with ARC. How do I enable ARC and have a workaround for this.Instead of setText what can I use?
它给了我一个错误，ARC 不允许将 NSInteger aka int 隐式转换为 NSString。我如何启用 ARC 并对此有一个解决方法。我可以使用什么来代替 setText？
abilitygeneration is set as NSInteger in TestAbility.h file.. thanks
能力生成在 TestAbility.h 文件中设置为 NSInteger ..谢谢

So if I've understood correctly, setText:takes an NSStringand you have an NSInteger? If that's correct you can explicitly convert them as follows:
所以，如果我理解正确的话，setText:取 anNSString并且你有一个NSInteger? 如果这是正确的，您可以按如下方式显式转换它们：
[self.abilitygeneration setText:[NSString stringWithFormat:@"%d",((TestAbility *)[self.testabilities objectAtIndex:0]).abilitygeneration]];
