实例方法
joined()
返回此序列序列的元素,串联。
声明
func joined() -> FlattenSequence<Self>
返回值
此序列序列的元素的平面视图。
详述
在此示例中,三个范围的数组被展平,以便每个范围的元素可以依次迭代。
let ranges = [0..<3, 8..<10, 15..<17]
// A for-in loop over 'ranges' accesses each range:
for range in ranges {
print(range)
}
// Prints "0..<3"
// Prints "8..<10"
// Prints "15..<17"
// Use 'joined()' to access each element of each range:
for index in ranges.joined() {
print(index, terminator: " ")
}
// Prints: "0 1 2 8 9 15 16"
