Safe operation
NSArray *list = @[@"1", @"2", @"3", @"4", @"5"];
NSMutableArray *mList = [NSMutableArray arrayWithObject:list];
[mList check_objectAtIndex:10];
[mList check_addObject:@"10"];
[mList check_insertObject:@"item" atIndex:10];
[mList check_replaceObjectAtIndex:10 withObject:@"item"];
[mList check_removeObjectAtIndex:10];
Find
The find() method returns the value of the first element in the provided array that satisfies the provided testing function. If no values satisfy the testing function, nil is returned.
NSString *findItem = [list find:^BOOL(NSString * _Nonnull item) {
return [item isEqualToString:@"3"];
}];
Some
The some() method tests whether at least one element in the array passes the test implemented by the provided function. It returns true if, in the array, it finds an element for which the provided function returns true; otherwise it returns false. It doesn't modify the array.
BOOL isVerifySome = [list some:^BOOL(NSString * _Nonnull item) {
return item.integerValue > 3;
}];
Every
The every() method tests whether all elements in the array pass the test implemented by the provided function. It returns a Boolean value.
BOOL isVerifyEvery = [list every:^BOOL(NSString * _Nonnull item) {
return item.integerValue > 3;
}];
Filter
The filter() method creates a new array with all elements that pass the test implemented by the provided function.
NSArray *filterList = [list filter:^BOOL(NSString * _Nonnull item) {
return item.integerValue > 3;
}];
Map
The map() method creates a new array populated with the results of calling a provided function on every element in the calling array.
NSArray *mapList = [list map:^id(NSString * _Nonnull item) {
NSNumber *obj = [NSNumber numberWithInteger:item.integerValue];
return obj;
}];
Debounce
If the function is called all the time, the block will not be executed immediately, but it will only be executed once when there is no new call to the function after a period of time.
fnBlock test = [NSObject debounceWithBlock:^{
NSLog(@"***********debounce*************");
} waitTime:3.0];
test();
Throttle
If the function is called all the time, the block will be executed once in a certain period of time.
fnBlock test = [NSObject throttleWithBlock:^{
NSLog(@"***********Throttle*************");
} executeBeforeCycle:NO waitTime:3.0];
test();
