Question

我的XIB中有一个名为“txt”的文本框和一个名为“next”的按钮。现在点击下一步按钮我想打印myArray的值。

NSArray *myArray
 myArray = [NSArray arrayWithObjects:@"1",@"3",@"5",@"45",@"67",nil];

任何人都可以帮助我。

Answer 1

这样做

NSLog(@"%@", myArray);

Answer 2

NSArray *myArray  = [NSArray arrayWithObjects:@"1",@"3",@"5",@"45",@"67",nil];
-(IBAction)nextAction:(id)sender{

NSString *currentObj = txt.text;
int index = -1;

if(currentObj != nil&&[myArray containsObject:currentObj]){
index = [myArray indexOfObject:currentObj];
} 

index++;
if(index<myArray.count)
   txt.text = [myArray objectAtIndex:index];

}

Answer 3

button.title = [myArray objectatindex:index];

Answer 4

NSArray *myArray myArray = [NSArray arrayWithObjects:@"1",@"3",@"5",@"45",@"67",nil];

将其更改为

NSArray *myArray = [NSArray arrayWithObjects:@"1",@"3",@"5",@"45",@"67",nil];

否则你注定要失败：D
