NSArray *ary = @[@"我",@"是",@"張",@"小",@"倍",@"er"];
for (int i = 0; i < ary.count; i ++) {
NSLog(@"%@",[ary objectAtIndex:i]);
}
2.使用for in 進行遍歷
NSArray *ary = @[@"我",@"是",@"張",@"小",@"倍",@"er"];
for (NSString *str in ary) {
NSLog(@"%@",str);
}
3.使用do while
NSArray *ary = @[@"我",@"是",@"張",@"小",@"倍",@"er"];
int i = 0;
do {
NSLog(@"%@",[ary objectAtIndex:i]);
i ++;
} while (i < ary.count);
}
4.使用while do?
NSArray *ary = @[@"我",@"是",@"張",@"小",@"倍",@"er"];
int i = 0;
while (i < ary.count) {
NSLog(@"%@",[ary objectAtIndex:i]);
i ++;
}
5.使用快速枚舉
NSArray *ary = @[@"我",@"是",@"張",@"小",@"倍",@"er"];
[ary enumerateObjectsUsingBlock:^(id? _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
NSLog(@"%ld,%@,%@",idx ,[ary objectAtIndex:idx],obj);
}];
6.
NSArray *ary = @[@"我",@"是",@"張",@"小",@"倍",@"er"];
dispatch_queue_t queue = dispatch_queue_create("queue", DISPATCH_QUEUE_CONCURRENT);
dispatch_apply([ary count],queue, ^(size_t index){
NSLog(@"%ld,%@",index,[ary objectAtIndex:index]);
});
