Question

NSArray有3个值

@[@"addd:etyrhetwrwr", @"fdfdd:jjjjhhhh", @"fsuy:jjhwgggggg"]

我想用自动换行将这个数组放入UILabel。因此，当我跑步时，它应该在标签中显示。

addd:etyrhetwrwr
fdfdd:jjjjhhhh
fsuy:jjhwgggggg

但我不能将这个NSArray分开。我怎么能这样做？

Answer 1

NSArray *myArray = @[@"addd:etyrhetwrwr", @"fdfdd:jjjjhhhh", @"fsuy:jjhwgggggg"];
NSString *labelString = [myArray componentsJoinedByString:@"\n"];

然后使用labelString设置标签text属性。

Answer 2

试试这个

NSArray *yourArray = @[@"addd:etyrhetwrwr", @"fdfdd:jjjjhhhh", @"fsuy:jjhwgggggg"];
NSString *string = [myArray componentsJoinedByString:@"\n"];
[yourLabel setText:string];

Answer 3

您可以通过

分隔UILabel中的NSArray

NSArray myArr = @[@"addd:etyrhetwrwr", @"fdfdd:jjjjhhhh", @"fsuy:jjhwgggggg"];
NSString strLabel = [myArr string:@"\n"];

Answer 4

试试这段代码

    NSArray *array = [[NSArray alloc] initWithObjects:@"adad",@"fgfdgdfg",@"sddgfs", nil];
    NSMutableString *strFinalData = [[NSMutableString alloc] init];

    for (int i=0; i<[array count]; i++)
    {
        [strFinalData appendFormat:@"%@ ",[array objectAtIndex:i]];
    }

    NSLog(@"Final String: %@",strFinalData);

现在设置yourLabel.text = strFinalData;

如何分离NSArray值？
