如果字符串以 @ 开头，则删除对象"type(music)"

Question

如果有一个包含许多字符串的NSMutableArray。是否可以删除所有以"类型（音乐）"开头的对象？数组如下所示：

[0] = type(movie),name...
[1] = type(music),name...
[2] = type(movie),name...
[3] = type(movie),name...
[4] = type(music),name...

Answer 1

您可以使用循环删除以"type（music）"开头的对象。

NSMutableArray *array = ...;
for (NSString *string in array) {
    if ([string hasPrefix:@"type(music)"]) {
        [array removeObject:string];
    }
}
